I have recently started to integrate Twig in my ProcessWire projects to have a better separation between logic and views as well as have cleaner, smaller template files as opposed to large multi-purpose PHP-templates. Though there is a Twig module, I have opted to initialize twig manually to have more control over the structure and settings of the twig environment. This is certainly not required to get started, but I find that having no "secret sauce" gives the me as a developer more agency over my code structure, and better insights into how the internals of the libraries I'm using work. Framework like Drupal or Craft have their own Twig integration, which comes with some opinionated standards on how to organize your templates. Since Twig is not native to ProcessWire, integrating Twig requires one to build a solid template structure to be able to keep adding pages and partials without repeating oneself or having templates grow to unwieldy proportions. This will be an (opinionated) guide on how to organize your own flexible, extensible template system with ProcessWire and Twig, based on the system I developed for some projects at work. Somehow this post got way too long, so I'm splitting it in two parts. I will cover the following topics: Part 1: Extendible template structures How to initialize a custom twig environment and integrate it into ProcessWire How to build an extendible base template for pages, and overwrite it for different ProcessWire templates with custom layouts and logic How to build custom section templates based on layout regions and Repeater Matrix content sections Part 2: Custom functionality and integrations How to customize and add functionality to the twig environment How to bundle your custom functionality into a reusable library Thoughts on handling translations A drop-in template & functions for responsive images as a bonus However, I will not include a general introduction to the Twig language. If you are unfamiliar with Twig, read the Twig guide for Template Designers and Twig for Developers and then come back to this tutorial. That's a lot of stuff, so let's get started ? Initializing the Twig environment First, we need to install Twig. If you set up your site as described in my tutorial on setting up Composer, you can simply install it as a dependency: composer require "twig/twig:^2.0" I'll initialize the twig environment inside a prependTemplateFile and call the main render function inside the appendTemplateFile. You can use this in your config.php: $config->prependTemplateFile = '_init.php'; $config->appendTemplateFile = '_main.php'; Twig needs two things: A FilesystemLoader to load the templates and an Environment to render them. The FilesystemLoader needs the path to the twig template folder. I'll put my templates inside site/twig: $twig_main_dir = $config->paths->site . 'twig'; $twig_loader = new \Twig\Loader\FilesystemLoader($twig_main_dir); As for the environment, there are a few options to consider: $twig_env = new \Twig\Environment( $twig_loader, [ 'cache' => $config->paths->cache . 'twig', 'debug' => $config->debug, 'auto_reload' => $config->debug, 'strict_variables' => false, 'autoescape' => true, ] ); if ($config->debug) { $twig_env->addExtension(new \Twig\Extension\DebugExtension()); } Make sure to include a cache directory, or twig can't cache the compiled templates. The development settings (debug, auto_reload) will be dependent on the ProcessWire debug mode. I turned strict_variables off, since it's easier to check for non-existing and non-empty fields with some parts of the ProcessWire API. You need to decide on an escaping strategy. You can either use the autoescape function of twig, or use textformatters to filter out HTML tags (you can't use both, as it will double escape entities, which will result in a broken frontend). I'm using twig's inbuilt autoescaping, as it's more secure and I don't have to add the HTML entities filter for every single field. This means pretty much no field should use any entity encoding textformatter. I also added the Debug Extension when $config->debug is active. This way, you can use the dump function, which makes debugging templates much easier. Now, all that's left is to add a few handy global variables that all templates will have access to, and initialize an empty array to hold additional variables defined by the individual ProcessWire templates. // add the most important fuel variables to the environment foreach (['page', 'pages', 'config', 'user', 'languages', 'sanitizer'] as $variable) { $twig_env->addGlobal($variable, wire($variable)); }; $twig_env->addGlobal('homepage', $pages->get('/')); $twig_env->addGlobal('settings', $pages->get('/site-settings/')); // each template can add custom variables to this, it // will be passed down to the page template $variables = []; This includes most common fuel variables from ProcessWire, but not all of them. You could also just iterate over all fuel variables and add them all, but I prefer to include only those I will actually need in my templates. The "settings" variable I'm including is simply one page that holds a couple of common settings specific to the site, such as the site logo and site name. Page templates By default, ProcessWire loads a PHP file in the site/templates folder with the same name of the template of the current page; so for a project template/page, that would be site/templates/project.php. In this setup, those files will only include logic and preprocessing that is required for the current page, while the Twig templates will be responsible for actually rendering the markup. We'll get back to the PHP template file later, but for the moment, it can be empty (it just needs to exist, otherwise ProcessWire won't load the page at all). For our main template, we want to have a base html skeleton that all sites inherit, as well as multiple default regions (header, navigation, content, footer, ...) that each template can overwrite as needed. I'll make heavy use of block inheritance for this, so make sure you understand how that works in twig. For example, here's a simplified version of the html skeleton I used for a recent project: {# site/twig/pages/page.twig #} <!doctype html> <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>{% block title %}{{ '%s | %s'|format(page.get('title'), homepage.title) }}{% endblock %}</title> <link rel="stylesheet" type="text/css" href="{{ config.urls.site }}css/main.css"> </head> <body class="{{ page.template }}"> {% block navigation %}{{ include("components/navigation.twig") }}{% endblock %} {% block header %}{{ include("components/header.twig") }}{% endblock %} {% block before_content %}{% endblock %} {% block content %} {# Default content #} {% endblock %} {% block after_content %}{% endblock %} {% block footer %}{{ include("components/footer.twig") }}{% endblock %} </body> </html> All layout regions are defined as twig blocks, so each page template can override them individually, without having to touch those it doesn't need. I'll fill the content block with default content soon, but for now this will do. Now, templates for our content types can just extend this base. This is the template for the homepage: {# site/twig/templates/pages/page--home.twig #} {% extends "pages/page.twig" %} {# No pipe-seperated site name on the homepage #} {% block title page.get('title') %} {# The default header isn't used on the homepage #} {% block header %}{% endblock %} {# The homepage has a custom slider instead of the normal header #} {% block before_content %} {{ include('sections/section--homepage-slider.twig', { classes: ['section--homepage-slider'] }) }} {% endblock %} Note that I don't do most of the actual html markup in the page templates, but in individual section templates (e.g. section--homepage-slider.twig) that can be reused across content types. More on this in the next section. We still need to actually render the template. The page template (which will be the entry point for twig) will be loaded in our _main.php, which we defined as the appendTemplateFile earlier, so it will always be included after the template specific PHP file. $template_file = 'pages/page--' . $page->template->name . '.twig'; $twig_template = file_exists($twig_main_dir . '/' . $template_file) ? $template_file : 'pages/page.twig'; echo $twig_env->render($twig_template, $variables); This function checks if a specific template for the current content type exists (e.g. pages/page--home.twig) and falls back to the default page template if it doesn't (e.g. pages/page.twig). This way, if you want a blank slate for a specific content type, you can just write a twig template that doesn't extend page.twig, and you will get a blank page ready to be filled with whatever you want. Note that it passes the $variables we initialized in the _init.php. This way, if you need to do any preprocessing or data crunching for this request, you can do it inside the PHP template and include the results in the $variables array. At this point, you can start building your default components (header, footer, navigation, et c.) and they will be included on every site that extends the base page template. Custom sections Now we've done a great deal of setup but haven't actually written much markup yet. But now that we have a solid foundation, we can add layout components very easily. For most of my projects, I use the brilliant Repeater Matrix module to set up dynamic content sections / blocks (this is not the focus of this tutorial, here's a detailed explanation). The module does have it's own built-in template file structure to render it's blocks, but since it won't work with my Twig setup, I'll create some custom twig templates for this. The approach will be the same as with the page template itself: create a "base" section template that includes some boilerplate HTML for recurring markup (such as a container element to wrap the section content in) and defines sections that can be overwritted by section-specific templates. First, let's create a template that will iterate over our the Repeater Matrix field (here it's called sections) and include the relevant template for each repeater matrix type: {# components/sections.twig #} {% for section in page.sections %} {% set template = 'sections/section--' ~ section.type ~ '.twig' %} {{ include( [template, 'sections/section.twig'], { section: section }, with_context = false ) }} {% endfor %} Note that the array syntax in the include function tells Twig to render the first template that exists. So for a section called downloads, it will look look for the template sections/section--downloads.twig and fallback to the generic sections/section.twig. The generic section template will only include the fields that are common to all sections. In my case, each section will have a headline (section_headline) and a select field to choose a background colour (section_background) : {# sections/section.twig #} {% set section_classes = [ 'section', section.type ? 'section--' ~ section.type, section.section_background.first.value ? 'section--' ~ section.section_background.first.value ] %} <div class="{{ section_classes|join(' ')|trim }}"> <section class="container"> {% block section_headline %} {% if section.section_headline %} <h2 class="section__headline">{{ section.section_headline }}</h2> {% endif %} {% endblock %} {% block section_content %} {{ section.type }} {% endblock %} </section> </div> This section template generates classes based on the section type and background colour (for example: section section--downloads section--green) so that I can add corresponding styling with CSS / SASS. The specific templates for each section will extend this base template and fill the block section_content with their custom markup. For example, for our downloads section (assuming it contains a multivalue files field download_files): {# sections/section--download.twig #} {% extends "sections/section.twig" %} {% block section_content %} <ul class="downloads"> {% for download in section.download_files %} <li class="downloads__row"> <a href="{{ download.file.url }}" download class="downloads__link"> {{ download.description ?: download.basename }} </a> </li> {% endfor %} </ul> {% endblock %} It took some setup, but now every section needs only care about their own unique fields and markup without having to include repetitive boilerplate markup. And it's still completely extensible: If you need, for example, a full-width block, you can just not extend the base section template and get a clean slate. Also, you can always go back to the base template and add more blocks as needed, without having to touch all the other sections. By the way, you can also extend the base section template from everywhere you want, not only from repeater matrix types. Now we only need to include the sections component inside the page template {# pages/page.twig #} {% block content %} {% if page.hasField('sections') and page.sections.count %} {{ include('components/sections.twig' }} {% endif %} {% endblock %} Conclusion This first part was mostly about a clean environment setup and template structure. By now you've probably got a good grasp on how I organize my twig templates into folders, depending on their role and importance: blocks: This contains reusable blocks that will be included many times, such as a responsive image block or a link block. components: This contains special regions such as the header and footer that will probably be only used once per page. sections: This will contain reusable, self-contained sections mostly based on the Repeater Matrix types. They may be used multiple times on one page. pages: High-level templates corresponding to ProcessWire templates. Those contain very little markup, but mostly include the appropriate components and sections. Depending on the size of the project, you could increase or decrease the granularity of this as needed, for example by grouping the sections into different subfolders. But it's a solid start for most medium-sized projects I tackle. Anyway, thanks for reading! I'll post the next part in a couple of days, where I will go over how to add more functionality into your environment in a scalable and reusable way. In the meantime, let me know how you would improve this setup!4 points

Thanks for testing. And yes, this is right. But for me personally, (and for most of my clients), the main goal is to present pages with text and images on the screen, and not to let the visitors save images for later use. I think, if a visitor need a visual copy of a page, he still can save the complete page with his browser, or he can do screenshots. On photographer sites, the use of images independend from viewing the site / page are often prohibited. There it even should not be recognized that images with filetype jpeg in real are weppys. But that is my personal opinion, and maybe thats not a sufficient reason to include this into the PW htaccess. But it also could be done the other way round: send .webp in markup and let the htaccess directives change this to (png|jpg) if a) the browser doesn't support this, or b) if there is no webp file available. This way round, in a 100% perfect site, all newer browsers would get 100% webp with correct file type. Only older browsers would get jpegs or pngs with file type webp. ?4 points

you may use the new debug info for images. and / or skip the rewrite: /site/assets/files/1/basename.jpg?skiprewrite And: nobody is forced to use it this way. You always can create conditional markup. My goal is to collect different solutions, and with the .htaccess only, to show and discuss a solution that would not need a rewrite for existing sites, or at least, makes the rewrite as small as possible. (change all image variations in markup from .jpg to .webp). EDIT: I think maintainers should know about the fact if they have implemented a webp solution and if so, wich one. If, for what ever reason, someone don't like this solution in a site, he shouldn't use it.3 points

Just a brief update today. I’m going to give it another week before bumping the core version, as I don’t think there’s enough changes yet to warrant a version bump. For whatever reason, several of my clients have needed integration with Stripe (payments) over the last few weeks. I’d not worked with it before the last month or so, but now all of the sudden am working with it a lot, because that's what my clients have asked for. I’ve found myself working on four different Stripe integrations on existing PW sites, both Stripe Elements and Stripe Checkout. None of these are for sites that have an actual “store” where they would need a cart, but rather just “pay for your reservation”, “buy this book”, “buy this song”, and “make a donation of $10”, “make a recurring donation”, type things. After doing a few of these, I thought it would make a lot of sense to have this built into FormBuilder, which would save us time on this stuff. So this week I built Stripe support into FormBuilder (using the Stripe Elements API). It’s already fully functional, so I will be releasing a new version of FormBuilder with this capability quite soon. To add a Stripe payment input to your form you just add a new field of type “Stripe payment for FormBuilder”, and then it asks you for some info about it (like amount to charge) and then your form works as a payment processor. Stripe has a clever way of making this all work, so that the user never leaves your site, but your site (and FormBuilder) never sees credit card numbers or anything like that, so it’s secure and you don’t have to consider things like PCI compliance. I've also got some other unrelated updates for FormBuilder that I'll be covering soon as well. Have a great weekend!2 points

This module (github) does with site/assets/files what Ryan's DatabaseBackups module does with the database: Backup site/assets Download ZIP archive Upload ZIP archive Restore site/assets Motivation: This module can be the missing part for projects with content backup responsibility on the client's side: The client will be able to download DB and assets/files snapshots through the backend without filesystem access, thus backing up all content themselves. Release state alpha – do not use in production environments. Credits for the nice UI go to @ryan – I reused most of it and some other code from the DatabaseBackups module.2 points

Because of this, is it worth also confusing the maintainers of the site? When debugging issues, it is easy to trip over files named in misleading ways.2 points

Module method name create() was the problem... Changed to add() to have the same naming than permissions page-* and it works fine!2 points

Hi everybody ? Just realized that redirecting to HTTPS does not work when ProCache is enabled (of course it does not work, but I didn't think of it...). The problem with redirecting via the default .htaccess rule is that it will also redirect to https on your dev environment. But you can easily exclude any domains from this redirect rule like this: # ----------------------------------------------------------------------------------------------- # 9. If you only want to allow HTTPS, uncomment the RewriteCond and RewriteRule lines below. # ----------------------------------------------------------------------------------------------- RewriteCond %{HTTPS} off RewriteCond %{HTTP_HOST} !.*\.test$ [NC] RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] Maybe that helps someone else as well.2 points

Another update to the PageImage class, comes in handy during the webp work. But it is not only useful for WebP copies, but for everything in regards of experimenting and debugging with images. I added a new method: ->getDebugInfo($options). See examples here: https://biriba.de/pw_pop3/pw_pageimage_getdebuginfo/2 points

I've been working with ProcessWire for a while now, and I've noticed that using Composer to manage dependencies and autoload external libraries isn't as prevalent in ProcessWire development as in other areas of PHP programming. I started out by using the default setup recommend in this blogpost. However, one major problem I have with this approach is that all external dependencies live in the webroot (the directory the server points to), which is unfavourable from a security standpoint and, in my opinion, just feels a bit messy. In this tutorial, I want to go through a quick setup of Composer and ProcessWire that keeps the dependencies, all custom-written code and other source material outside of the webroot, and makes full usage of the Composer autoloader. This setup is pretty basic, so this tutorial is probably more useful to beginners (this is why I'll also include some general information on Composer), but hopefully everyone can take something away from this for their personal workflow. Site structure after setup This is what the directory structure can look like after the setup: . ├── composer.json ├── composer.lock ├── node_modules │ └── ... ├── public │ ├── index.php │ ├── site │ ├── wire │ └── ... ├── packacke-lock.json ├── package.json ├── sass │ ├── main.scss │ ├── _variables.scss │ └── ... ├── src │ ├── ContentBag.php │ └── ... └── vendor ├── autoload.php ├── composer ├── league ├── symfony └── ... As mentioned, the main point of this setup is to keep all external libraries, all other custom source code and resources out of the webroot. That includes Composer's vendor folder, your node_modules and JavaScript source folder if you are compiling JavaScript with webpack or something similar and including external scripts via NPM, or your CSS preprocessor files if you are using SASS or LESS. In this setup, the public directory acts as the webroot (the directory that is used as the entry point by the server, DocumentRoot in the Apache configuration). So all other files and directories in the mysite folder aren't accessible over the web, even if something goes wrong. One caveat of this setup is that it's not possible to install ProcessWire modules through Composer using the PW Module Installer (see Blogpost above), but that's just a minor inconvenience in my experience. Installation You'll need to have composer installed on your system for this. Installation guides can be found on getcomposer.org. First, open up your shell and navigate to the mysite folder. $ cd /path/to/mysite/ Now, we'll initialize a new Composer project: $ composer init The CLI will ask some questions about your projects. Some hints if you are unsure how to answer the prompts: Package names are in the format <vendor>/<project>, where vendor is your developer handle. I use my Github account, so I'll put moritzlost/mysite (all lowercase). Project type is project if you are creating a website. Author should be in the format Name <email>. Minimum Stability: I prefer stable, this way you only get stable versions of dependencies. License will be proprietary unless you plan on sharing your code under a FOSS license. Answer no to the interactive dependencies prompts. This creates the composer.json file, which will be used to keep track of your dependencies. For now, you only need to run the composer install command to initialize the vendor directory and the autoloader: $ composer install Now it's time to download and install ProcessWire into the public directory: $ git clone https://github.com/processwire/processwire public If you don't use git, you can also download ProcessWire manually. I like to clean up the directory after that: $ cd public $ rm -r .git .gitattributes .gitignore CONTRIBUTING.md LICENSE.TXT README.md Now, setup your development server to point to the /path/to/mysite/public/ directory (mind the public/ at the end!) and install ProcessWire normally. Including & using the autoloader With ProcessWire installed, we need to include the composer autoloader. If you check ProcessWire's index.php file, you'll see that it tries to include the autoloader if present. However, this assumes the vendor folder is inside the webroot, so it won't work in our case. One good place to include the autoloader is using a site hook file. We need the autoloader as early as possible, so we'll use init.php: EDIT: As @horst pointed out, it's much better to put this code inside the config.php file instead, as the autoloader will be included much earlier: // public/site/config.php <?php namespace Processwire; require '../../vendor/autoload.php'; The following also doesn't apply when including the autoloader in the config-file. This has one caveat: Since this file is executed by ProcessWire after all modules had their init methods called, the autoloader will not be available in those. I haven't come across a case where I needed it this early so far; however, if you really need to include the autoloader earlier than that, you could just edit the lines in the index.php file linked above to include the correct autoloader path. In this case, make sure not to overwrite this when you update the core! Now we can finally include external libraries and use them in our code without hassle! I'll give you an example. For one project, I needed to parse URLs and check some properties of the path, host et c. I could use parse_url, however that has a couple of downsides (specifically, it doesn't throw exceptions, but just fails silently). Since I didn't want to write a huge error-prone regex myself, I looked for a package that would help me out. I decided to use this URI parser, since it's included in the PHP League directory, which generally stands for high quality. First, install the dependency (from the project root, the folder your composer.json file lives in): $ composer require league/uri-parser This will download the package into your vendor directory and refresh the autoloader. Now you can just use the package in your own code, and composer will autoload the required class files: // public/site/templates/basic-page.php <?php namespace Processwire; use \League\Uri\Parser; // ... if ($url = $page->get('url')) { $parser = new Parser(); $parsed_url = $parser->parse($url); // do stuff with $parsed_url ... } Wiring up custom classes and code Another topic that I find really useful but often gets overlooked in Composer tutorials is the ability to wire up your own namespace to a folder. So if you want to write some object-oriented code outside of your template files, this gives you an easy way to autoload those using Composer as well. If you look at the tree above, you'll see there's a src/ directory inside the project root, and a ContentBag.php file inside. I want to connect classes in this directory with a custom namespace to be able to have them autoloaded when I use them in my templates. To do this, you need to edit your composer.json file: { "name": "moritzlost/mysite", "type": "project", "license": "proprietary", "authors": [ { "name": "Moritz L'Hoest", "email": "info@herebedragons.world" } ], "minimum-stability": "stable", "require": {}, "autoload": { "psr-4": { "MoritzLost\\MySite\\": "src/" } } } Most of this stuff was added during initialization, for now take note of the autoload information. The syntax is a bit tricky, since you have to escape the namespace seperator (backslash) with another backslash (see the documentation for more information). Also note the PSR-4 key, since that's the standard I use to namespace my classes. The line "MoritzLost\\MySite\\": "src/" tells Composer to look for classes under the namespace \MoritzLost\MySite\ in the src/ directory in my project root. After adding the autoload information, you have to tell composer to refresh the autoloader information: $ composer dump-autoload Now I'm ready to use my classes in my templates. So, if I have this file: // src/ContentBag.php <?php namespace MoritzLost\MySite; class ContentBag { // class stuff } I can now use the ContentBag class freely in my templates without having to include those files manually: // public/site/templates/home.php <?php namespace Processwire; use MoritzLost\MySite\ContentBag; $contentbag = new ContentBag(); // do stuff with contentbag ... Awesome! By the way, in PSR-4, sub-namespaces correspond to folders, so I can put the class MoritzLost\MySite\Stuff\SomeStuff in src/Stuff/SomeStuff.php and it will get autoloaded as well. If you have a lot of classes, you can group them this way. Conclusion With this setup, you are following secure practices and have much flexibility over what you want to include in your project. For example, you can just as well initialize a JavaScript project by typing npm init in the project root. You can also start tracking the source code of your project inside your src/ directory independently of the ProcessWire installation. All in all, you have good seperation of concerns between ProcessWire, external dependencies, your templates and your OOP-code, as well as another level of security should your Server or CGI-handler ever go AWOL. You can also build upon this approach. For example, it's good practice to keep credentials for your database outside the webroot. So you could modify the public/site/config.php file to include a config or .env file in your project root and read the database credentials from there. Anyway, that's the setup I came up with. I'm sure it's not perfect yet; also this tutorial is probably missing some information or isn't detailed enough in some areas depending on your level of experience. Feel free to ask for clarification, and to point out the things I got wrong. I like to learn as well ? Thanks for making it all the way to the bottom. Cheers!1 point

@Robin S Thanks for your clarification. I was afraid you would say so, but was just thinking if it would be possible for me to modify the dialogue files and have an extra option added like the other attribute options - something like: attribute__options=Option1|Option2 but with some extra logic: attribute__requirements=required or similar. My idea is that from the dropdown menu, the user is provided a choice of multiple blocks and once one is selected, the dialogue opens up and can intercept an eventual requirement set thorugh the module. Once the user has finished and press OK, if he double clicks on the HC he is still seeing the same code so technically it would be difficult for the user to change the text etc. and is presented a nice "reminder" of an empty attribute or else. On the other thought, the present functionality might be a better option for me as I am allowing a user to choose a news tab category (1 out of 10) so he can leave 1 empty, 2 empty and then add 3, 4 etc. Will see how it would be completted to fit the requirements and avoid any errors as presently I am grouping all the attributes to an array, then have to clean the empty values, then to reorder and then to apply it. But hey, it works and it was super easy for my 8 years old boy I've tested with to add the block, pick categories, limit the number of pages shown etc. GREAT THANK YOU FOR THE EFFORTS AND MODULE!1 point

@MilenKo, it's not possible to have a required field in the dialog because the dialog form is not submitted anywhere for ProcessWire validation - the field values are just captured via Javascript when the dialog is closed. You should check for empty field values in the code for your Hanna tag. Incidentally, this is true for any "required" field anywhere in PW because nothing is ever really required - the user can simply abandon the edit process if they want and leave unfilled required fields, so you always need to check that fields are actually populated before doing anything with their value.1 point

Another possibility is to use different names for htaccess files for local development and for live servers. In your local httpd.conf you can set for AccessFilename something like AccessFileName .htaccess.test or AccessFileName .htaccess.local where you can define different settings for local development by keeping the .htaccess file untouched for online server settings.1 point

Thank you very much for this starting tutorial! I love to work with Twig. I am switching over from OctoberCMS to Processwire and it is hard to get over from Twig template files to a plain PHP. So I am happy to have a starting point to start working with Twig in my Processwire Projects. Greetings from Austria to Germany1 point

@teppo no problem. That is usually what I do but maybe I've over drank the coffee and got too much coding that day ? P.S. I kind of completted my task by adding some checks in the code but it would be useful to know if I can add some checks before submitting the values of parameters to Hanna Code. Maybe I should check with @Robin S as he is the developer of HC Dialogues and it seems like the module addition could be easier to manupulate.1 point

I have a Digital Ocean CentOS cloud server that only exposes the web server and SSH to the outside world, and SSH only with passwordless key-based logins. Linux has a program sshfs (ssh file system) which allows you to mount a remote directory tree via ssh, and then the mounted files act just like they were local files on your workstation, and you can run vscode on your workstation using the sshfs mounted filesystem as the workspace. sshfs has a user/group map file you can use to properly map the user account from your workstation to the user/group account on the server, so files you edit/create end up with the proper file ownership on the server. The hitch in the gitalong is that I've never found a satisfactory sshfs implementation for windows. I've read there is some sshfs extension for vscode but haven't ever tried it. For myself, since I have a full-time linux server here that I use as a file server for my windows machines, I also have samba running on the linux machine to expose directory trees to windows, I can sshfs mount the cloud server files to a mount point on my local linux server, then I can expose the sshfs mount point through a samba share to my windows 10 workstaiton, fire up vscode in windows 10, navigate using windows file explorer to the mount point where the remote cloud server is mounted, and voila! Plus I can open a putty connection to the cloud server and have command-line access to the remote files. Works for me, ymmv.1 point

I think the Github acquisition all ties back to selling Cloud and other services to the Developer community. MS is now a services company as Nadella likes to state. I guess future iterations of Github where it integrates with Azure and other MS Products will be the telltale sign1 point

Glad to hear that. Removed your projectname already.1 point

It's working here in Laragon, Windows. But won't this have the effect that if a visitor saves the image from their browser they will be saving a WEBP image with a JPG (PNG, GIF, etc) file extension? Might cause some confusion.1 point

Please can someone test the .htaccess solution for WebP support in other environments? It is not much work, you don't have to install test branches or anything else. You only need to copy some lines into your .htaccess file and create a single webp image with the tool of your choice. Or if you don't have a converter tool for webp, simply make a copy of a jpeg and rename it with type .webp instead of .jpg. Steps to proceed: Copy the rewrite directives into the top of your .htaccess file Grab any image variation you already have embedded into a PW site, create a webp variation of and save it into the same assets/files/{ID}/ folder. (Maybe you want to invert the colors of the webp copy for better detection!) Create or go to a page where this image should be rendered as jpeg in a regular img tag, and look if the webp copy is served and displayed. (Don't forget to flush browser caches) The .htaccess code: My matched.php for debugging: Examples in Opera with opened Network-Tab, requesting one image that has a webp copy, and requesting the second image that do not have a webp copy: Same page in Opera and old IE11: If we have a wider test case, the chance that this can be embedded into the PW .htaccess file for optional usage (commented by default) would be helpful for many users to support webp with less effort on their sites!1 point

I think you should go ahead and file it as a bug report because superusers shoud be able to trash/delete.1 point

Hi @Tom. the new code is online in my test branch. And following is a test with also the .htaccess solution installed. My template code: <?php $image1 = $page->images->first->size(100, 100, $options); ?> <img src="<?=$image1->url?>" alt="<?=$image1->alt?>" /> <img src="<?=$image1->url?>?skiprewrite" alt="<?=$image1->alt?>" /> <?php $image2 = $page->images->first->size(100, 100, $options); ?> <img src="<?=$image2->url?>" alt="<?=$image2->alt?>" /> <img src="<?=$image2->url?>?skiprewrite" alt="<?=$image2->alt?>" /> The quality settings for the regular variation is set to 10, it is created first in the image engines. The webpQuality was set to 100, and it is created after the regular variation. The following screen first shows the webp copy and due to the "?skiprewrite" GET varname, it shows the (distorted) jpegs at second place. Once with GD and once with IMagick: I really love the .htaccess only solution! With this, you simply can update any existing site by upgrade to the new PW core that include the webp support and running a maintenance script over all image variations to create the webp copies. After that you are done! ?1 point

I have played with a .htaccess only solution to serve WEBP instead of JPEGs or PNGs. This way you can - leave your existing template markup untouched, and the apache_rewrite will - detect if the browser supports WEBP - if a WEBP copy is available for a JPEG or PNG image. Locally it's working out nicely! ? This markup automatically serves a WEBP copy to all browsers that support it: $options = ['webpAdd'=>true, 'webpQuality'=>90]; $image = $page->images->first()->size(300, 300, $options); // this will create a 300x300 Thumb for JPEGs and PNGs with an additional WEBP copy ?> <img src="<?=$image->src?>" alt="<?=$image->alt?>" /> <!-- this will serve the WEBP image to all Browsers that supports it, and the JPEG/PNG to other browsers --> AddType image/webp .webp <IfModule mod_rewrite.c> RewriteEngine On AddDefaultCharset UTF-8 ### Redirect regular PW JPEGs and PNGs to their WEBP image copies, ### if available and if the Browser supports WEBP: ## Does Browser accept WEBP images? RewriteCond %{HTTP_ACCEPT} image/webp ## Is it an existing file? RewriteCond %{REQUEST_FILENAME} -f ## Does a WEBP copy exist for it? RewriteCond %{DOCUMENT_ROOT}/$1$2$3/$4.webp -f ## With an added GET var or GET value of skiprewrite we do send the original JPEG or PNG RewriteCond expr "! %{QUERY_STRING} -strmatch '*skiprewrite*'" ## With an added GET var or GET value from the PW Page Editor, we do send the original JPEG or PNG RewriteCond expr "! %{QUERY_STRING} -strmatch 'nc=*'" ## Is it a regular PW JPEG or PNG image, stored under site/assets/files? RewriteRule ^(.*?)(site/assets/files/)([0-9]+)/(.*)\.(jpe?g|png)(.*)$ /$1$2$3/$4.webp [L] </IfModule> Adding a GET var or GET value with the string "skiprewrite" added to an image bypasses serving the WEBP copy in favour for the original variation. (Maybe useful for debug purposes!)1 point

@horst Thank you so much, I'm playing with this now - I'll let you know if I come across anything. Appreciate the hard work. Edit: Looking good! Edit: One thing I've noticed is let's say you set the quality of the jpeg to 50 on resize, WebP will use the resized jpeg at 50 quality. Does this mean that using also webpQuality 50 would compress it twice? @horst1 point

I have sent a pull request on github for webP support in the core: https://github.com/processwire/processwire/pull/141 Explanation of its usage: I implemented two new options for the imagesizer that can be set globally in the site/config.php or can be passed within an individual options array to any size-method: $options = [ "webpAdd" => true, // boolean, if true, an additional webp variation will be created "webpQuality" => 80 // integer range 0 - 100, 100 is best ]; This creates an additional webp variation file besides the regular JPEG, PNG or GIF variations. In the template files you have two new image properties to work with the webp variation: $image->hasWebp; // boolean, true indicates that a webp variation is available for that image variation ?> <img src="<?= $image->srcWebp ?>" alt="" /> So we can create conditional markup like in this example: $image = $page->images->first()->size(300, 300); ?> <picture> <?php if($image->hasWebp) { ?> <source srcset="<?=$image->srcWebp?>" type="image/webp" /> <?php } ?> <source srcset="<?=$image->src?>" type="image/jpeg" /> <img src="<?=$image->url?>" alt="Alt Text!" /> </picture> The pull request and my test branch are based on this weeks pw dev branch. So if someone want to test it, please grab a copy, play with it and report back here. I don't know what timeline @ryan has and what parts need to be modified / rearanged, etc. Maybe the property names or the option names will be changed, but I think the main functionality will be close to that in the current test branch. ----- And here are a filesize comparision with different quality settings and with both engines, GD-Lib and IMagick: EDIT: An approach without conditional markup for webp comes from @arjen see lazyload. ...1 point

What I've done so far, is a small implementation of webp-convert. Currently without a ProcessWire specific module or something, but that's planned. Just added a file called webp-on-demand.php in the ProcessWire root directory with following content: <?php // docs https://github.com/rosell-dk/webp-convert require 'webp/webp-on-demand-1.inc'; use WebPConvert\WebPConvert; $docRoot = rtrim($_SERVER["DOCUMENT_ROOT"], '/'); $requestUriNoQS = explode('?', $_SERVER['REQUEST_URI'])[0]; $source = $docRoot . urldecode($requestUriNoQS); $destination = $source . '.webp'; // Store the converted images besides the original images (other options are available!) $options = [ // Tell where to find the webp-convert-and-serve library, which will // be dynamically loaded, if need be. //'reconvert' => true, 'require-for-conversion' => 'webp/webp-on-demand-2.inc', 'quality' => 'auto', 'max-quality' => 75, 'fail' => 'serve-original' // see https://github.com/rosell-dk/webp-on-demand/blob/master/docs/api.md for more info ]; WebPConvert::convertAndServe($source, $destination, $options); Then in the folder webp the two on-demand files from here. After that I added following to the .htaccess: <IfModule mod_rewrite.c> RewriteEngine On # Redirect images to webp-on-demand.php (if browser supports webp) RewriteCond %{HTTP_ACCEPT} image/webp RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^(.*)\.(jpe?g|png)$ webp-on-demand.php [NC,L] </IfModule> AddType image/webp .webp And that's it. If the browser supports webp, all requests of .jpg and .png are redirectet to the webp-on-demand.php which desides if it needs to convert the image or serve the already converted one. A small caveat: the standard installation of Plesk has no webp support included, so on webservers with Plesk you either need to wait for their implementation or compile it yourself.1 point

@jens.martsch This is the example: https://www.dropbox.com/sh/ayqubd4b5o78i41/AAAm8eNmgBizOqfcG2YdT0Qta?dl=0 This is using quality 100, maxSize so no upscaling and sharpening none.1 point

Any news on WebP? There is a lot of convocation in the studio currently on image quality. The general thing is the built in resizing of images (Imagick) leaves images soft, however adding any sort of sharpening and it over sharpens around text leaving it with halos. Some people in the studio have been talking about changing CMS due to how ProcessWire manipulates images leaving them soft or over sharpened losing detail. It's a big discussion at the moment and generally we have found Statamic & CraftCMS much better at resizing images and keeping quality (Statamic uses Glide - https://glide.thephpleague.com/) But WebP will be massively important also.1 point

Can we make the api a bit more flexible like: $options = [ 'additionalFormats': ['webp'], 'webp' => [ 'quality' => 80 ] ]; This way we can easily add any other formats, which might emerge and have the possibility to not only have a single additional format generated. And as soon as we might generate multiple formats / images per sizing operation I feel like namespacing options like quality might prevent an explosion of possible root level options.1 point

Probably not news to anyone familiar with webp, but I just tried it and the reduction in file size is impressive indeed. WEBP image on the left generated from variation with 100% quality, JPG on the right with default PW quality setting. Interesting that there is a slight but perceptible difference in colour though.1 point

I don't understand them either. Was just working based of the sample's. I googled and it does not seem to matter if you use one block or more. I did quick and dirty fix... looking like this. Note I always have atleast 2 schemes and therefor kinda hardcoded the brackets. There is also a ',' between 2 schemes. <?php $jsonld = $modules->get('MarkupJsonLDSchema'); ?> <script type="application/ld+json">[ <?php switch ($page->template) { case 'product': $options = array( 'logo' => $pages->get(1)->logo->size(200, 200), 'image' => $page->images->first()->size(200, 200) ); echo $jsonld->render('Product', $options) . ","; echo $jsonld->render('BreadcrumbList'); break; case 'categorieen': $options_c = array( 'logo' => $pages->get(1)->logo->size(200, 200), 'description' => $page->summary, 'image' => $pages->get(1092)->images->first()->size(200, 200) ); echo $jsonld->render('Product', $options_c) . ","; echo $jsonld->render('BreadcrumbList'); break; default: $options = array( 'logo' => $pages->get(1)->logo->size(200, 200), 'image' => $page->images->first()->size(200, 200) ); echo $jsonld->render('WebPage', $options) . ","; echo $jsonld->render('LocalBusiness') . ","; echo $jsonld->render('BreadcrumbList'); break; } ?> ]</script>1 point

Try this in /site/ready.php $wire->addHookAfter('ProcessPageAdd::getAllowedTemplates', function(HookEvent $event) { // Get keys (IDs) of returned templates array $template_ids = array_keys($event->return); // Implode for use in a selector string $template_ids_str = implode('|', $template_ids); // Get TemplatesArray of those templates, sorted by label $templates = $this->templates->find("id=$template_ids_str, sort=label"); // Convert to plain array and return $event->return = $templates->getArray(); });1 point

It should be added, that this only works as long as the PageArray for the foreach is sorted by editorial, otherwise it would be needed to search the whole $editorials array for duplicates and not only the last item.1 point
