Hey folks!

I'm happy to finally introduce a project I've been working on for quite a while now: it's called Wireframe, and it is an output framework for ProcessWire.

Note that I'm posting this in the module development area, maily because this project is still in rather early stage. I've built a couple of sites with it myself, and parts of the codebase have been powering some pretty big and complex sites for many years now, but this should still be considered a soft launch 🙂

--

Long story short, Wireframe is a module that provides the "backbone" for building sites (and apps) with ProcessWire using an MVC (or perhaps MVVM – one of those three or four letter abbreviations anyway) inspired methodology. You could say that it's an output strategy, but I prefer the term "output framework" since in my mind the word "strategy" means something less tangible. A way of doing things, rather than a tool that actually does things.

Wireframe (the module) provides a basic implementation for some familiar MVC concepts, such as Controllers and a View layer – the latter of which consists of layouts, partials, and template-specific views. There's no "model" layer, since in this context ProcessWire is the model. As a module Wireframe is actually quite simple – not even nearly the biggest one I've built – but there's still quite a bit of stuff to "get", so I've put together a demo & documentation site for it at https://wireframe-framework.com/.

In addition to the core module, I'm also working on a couple of site profiles based on it. My current idea is actually to keep the module very light-weight, and implement most of the "opinionated" stuff in site profiles and/or companion modules. For an example MarkupMenu (which I released a while ago) was developed as one of those "companion modules" when I needed a menu module to use on the site profiles.

Currently there are two public site profiles based on Wireframe:

  • site-wireframe-docs is the demo&docs site mentioned above, just with placeholder content replaced with placeholder content. It's not a particularly complex site, but I believe it's still a pretty nice way to dig into the Wireframe module.
  • site-wireframe-boilerplate is a boilerplate (or starter) site profile based on the docs site. This is still very much a work in progress, but essentially I'm trying to build a flexible yet full-featured starter profile you can just grab and start building upon. There will be a proper build process for resources, it will include most of the basic features one tends to need from site to site, etc.

--

Requirements and getting started:

  • Wireframe can be installed just like any ProcessWire module. Just clone or download it to your site/modules/ directory and install. It doesn't, though, do a whole lot of stuff on itself – please check out the documentation site for a step-by-step guide on setting up the directory structure, adding the "bootstrap file", etc.
    • You may find it easier to install one of the site profiles mentioned above, but note that this process involves the use of Composer. In the case of the site profiles you can install ProcessWire as usual and download or clone the site profile directory into your setup, but after that you should run "composer install" to get all the dependencies – including the Wireframe module – in place.
  • Hard requirements for Wireframe are ProcessWire 3.0.112 and PHP 7.1+. The codebase is authored with current PHP versions in mind, and while running it on 7.0 may be possible, anything below that definitely won't work.

A feature I added just today to the Wireframe module is that in case ProcessWire has write access to your site/templates/ directory, you can use the module settings screen to create the expected directories automatically. Currently that's all, and the module won't – for an example – create Controllers or layouts for you, so you should check out the site profiles for examples on these. (I'm probably going to include some additional helper features in the near future.)

--

This project is loosely based on an earlier project called pw-mvc, i.e. the main concepts (such as Controllers and the View layer) are very similar. That being said, Wireframe is a major upgrade in terms of both functionality and architecture: namespaces and autoloader support are now baked in, the codebase requires PHP 7, Controllers are classes extending \Wireframe\Controller (instead of regular "flat" PHP files), implementation based on a module instead of a collection of drop-in files, etc.

While Wireframe is indeed still in a relatively early stage (0.3.0 was launched today, in case version numbers matter) for the most part I'm happy with the way it works, and likely won't change it too drastically anytime soon – so feel free to give it a try, and if you do, please let me know how it went. I will continue building upon this project, and I am also constantly working on various side projects, such as the site profiles and a few unannounced helper modules.

I should probably add that while Wireframe is not hard to use, it is more geared towards those interested in "software development" type methodology. With future updates to the module, the site profiles, and the docs I hope to lower the learning curve, but certain level of "developer focus" will remain. Although of course the optimal outcome would be if I could use this project to lure more folks towards that end of the spectrum... 🙂

Please let me know what you think – and thanks in advance!

I discovered Wireframe on Sunday after exploring the GitHub repo for the ProcessWire Composer Installer project that you mentioned in the latest PW Weekly. The documentation you've written for Wireframe is just awesome 👍 - engaging, comprehensive and clear.

I have a short question and a long question...

Does it make sense to use Wireframe together with Markup Regions in any way, or would a developer choose Wireframe or Markup Regions but not both?

 

The long question relates to what you said here:

I take this to be a reference to the superiority of a MVC approach versus the "default" approach of mixing business logic and UI logic together in a PW template file. I'd like to hear more of your views on this because you didn't talk about it much in the documentation, probably because MVC and the separation of concerns is discussed in plenty of other places around the web. But I was wondering if you think a MVC approach is always the way to go, or if is something you would weigh up the pros and cons of taking into account the parameters of each specific project, e.g. the scale and complexity of the project, if a team will be working on the project, etc.

Personally I use Markup Regions and don't use any separation of business logic and UI logic into different files or folders. From time to time I think about changing to an MVC approach because so many people seem to recommend it, but when I weigh it up I don't see enough advantage versus disadvantage for the kinds of projects I work on. But maybe I'm overlooking something so I'd appreciate your comments.

The main benefits of MVC as I understand it are...

1. If you have a team of people working on a project, maybe with different skill sets (e.g. a front-end dev and a back-end dev), then it lets each person focus on the parts that matter to them. For example the front-end person can focus on the view file without having to see any business logic which might distract or even be unintelligible to them. This totally makes sense to me and if I worked as part of a team this by itself would make an MVC approach worthwhile. But in my case I do everything alone from start to finish - design, front-end, back-end.

2. The business logic doesn't "belong" in the same file as the markup - it's better to keep it separate and it makes it easier to update a site. This seems more contentious to me, and perhaps depends on how much business logic there is. If I have some variable that I'm using within the markup I find it very handy to have the definition/construction of that variable present alongside its usage in output. So I'm not left wondering "what was it that I put into $related_products?" and needing to navigate to some other file to find out.

Now if there were heaps of business logic it might start to feel like clutter within the markup, but when I look at the template files for my projects in most cases there's actually very little business logic present. Maybe that's partly because PW is quite elegant in that you can do a lot with a few lines of code, and partly because most of my projects are not very complex. But even if I do have a lot of business logic I find that placing it at the top of the template file is no problem at all. If I need to work on it I'd rather just scroll up than open another file, and I can use my IDE to collapse any blocks of code that I don't need to focus on. Would you say that MVC is an approach that is more suited to complex projects rather than simple ones?

Things like layouts and partials that are offered through Wireframe are cool, but those are also possible with Markup Regions (layout = _main.php) and built-in PW methods (partials = $files->render).

I have no doubt that Wireframe is a powerful tool, but do you see it as being the right solution for all projects or just some projects?

Hey @Robin S. First of all thanks for your thoughtful message! I'll have to get back to some of your points later, but just wanted to share a few initial thoughts 🙂

About using Markup Regions and Wirerame together: I honestly don't know. I'm aware on a basic level of how Markup Regions work, but I've never used it. I will definitely dig into the specifics, though – this is an interesting area. On a more general note I've intentionally kept to the "alternate template file" strategy (instead of hooking into Page rendering or something similar) so that Wireframe can be used for some parts of the site (some templates), while other parts use whatever other approach makes sense.

So yeah, you can use them together, I'm just not yet sure to what extent that would make sense... if that makes sense to you? 😉

I don't really want to preach the superiority of MVC (or any other three or four letter architecture), but apart from some of the simplest sites I've built – isit.pw has one file with one form, so it for an example doesn't benefit from a whole lot of structure – I do generally prefer to separate "code" from "markup". This is a topic I'd love to cover in more detail later, but your two points summarise very well what it is all about. Project scope (and complexity) and working with or without a team are definitely key factors there. After that it comes down to personal preference.

TL;DR: I wouldn't use Wireframe for everything, but I do think that it fits nicely just about any project.

I often end up with multiple "views" for the same data – not sure if this is really a common need, but it has been in my projects, which is another reason to keep the views as basic (and as markup-y) as possible, and instead move all the business logic, data structuring, etc. somewhere else. Overall I've found that this sort of structure helps me keep things neat so that when things eventually grow and scale it doesn't become a mess, and allows me to make changes and additions with little extra overhead once they are due.

That being said, there's a good reason why Controllers – for an example – are actually optional components in Wireframe. Some of my templates make use of the whole package – Controller, layout, view file(s), and partials – yet others have just a single view file, and that's all. I like that I don't have to use more than I really need, but if I do need more later, I can just bolt it in without a whole lot of refactoring 🙂

It's true that you can use ProcessWire's built-in features to do everything that Wireframe does. That's exactly what Wireframe itself does: I've tried not to reinvent the wheel where possible, so the View (for an example) is a light-weight wrapper for TemplateFile, etc. Originally the predecessor of this project (pw-mvc) was all about standardising some best practices so that as we (as a team) build a project after project there's some common ground there. In a perfect world you could jump into a new project you've never touched before and instantly see what's going on in there.

It's a bit more than that now, though.

... and this is the point where I realise that my "few initial thoughts" are already getting quite long-winded 😅

Thanks @teppo. I'm going to spend some time exploring Wireframe to see how it feels compared to my existing approach - I may yet become a convert 🙂.

Thanks again for creating this tool and doing such a great job on the documentation website.

I am currently building first site using Wireframe. I really like it so far. I have almost done with the site (pretty simple one) and I didn't use any controllers... until now when I noticed that homepage shows feed that mixes news and events. Usually nothing too complex (just add both templates to selector), but in this case events are from separate system, pulled from REST API. So this was perfect case where I use controller for:

  • pulling data from external API
  • caching that data, so that we fetch only once in hour
  • merging and sorting it to one PageArray with local news items
  • passing that final PageArray to view file for easy rendering

Without Wireframe I would probably build much of that logic into functions, but I really like that there is "documented place where this kind of stuff should live". 

In future if I (or some other lucky fellow) need to make changes to layout - it is simple and one doesn't have to think about that "wow, all kinds of stuff is happening here", maybe remove that events stuff or add even more sources - I can do it easily without messing with layout. Also this model usually helps to produce clearer code: instead of many ifs (showing little bit different data for events vs. news) while rendering, I have that kind of logic separate from actual markup.

One downside is of course that one have to "understand" the mvc-framework and it's logic. You have to know that there might be controller involved and where it lives for example.

Sounds nice, we built some similar (but highly customised on some special internal needs...). But found many very similar things in it. 🙂

Nice! Would be interesting to hear if you can think of anything particularly cool that your version did and Wireframe doesn't do. Always looking for new ideas 🙂

Small update to the docs site: added a page for patterns and practices. Currently only one page there (utility classes), but will be adding more as I figure out what should be there. Doesn't make sense to bundle everything with the module or even the site profiles, so needed some place to stash this sort of stuff.

This time you came prepared, @teppo! Great intro post and a cool documentation site. Congratulations!

I did not have time to dig into it (yet). The 1st question that comes to mind is can twig or some other templating language be plugged in for the views?

Two more)

  1. How is it possible to separate logic for partials from their presentation? I often find the need to prepare content for partials same way as for the views.
  2. Do you have experience of using Wireframe with RepeaterMatrix based content?

Thanks, Ivan! 🙂

I haven't figured out the details yet, but at some point I'm going to look into adding templating language support. For the time being all options are open, so don't really have anything else to share at this point than "I will look into it eventually".

1. Currently partials are intended as simple drop-in (include) files with very little logic. I do have some ideas in my backlog that come pretty close to this topic, but I'll have to give them a bit more thought before implementing. Wouldn't want to put something in now, and then regret it right away... 😅

I've often preferred render functions, i.e. functions that generate markup, in case I need to bake some logic into smaller bits and pieces of the site. A "RenderUtils" class with multiple render methods would be one solution, and of course you can already use ProcessWire's own features to render a partial: $page->renderValue(), $files->render(), TemplateFile::render(), etc. In the long term perhaps we could add some kind of a helper class to the framework for handling these situations – just not quite sure yet how to approach this.

If you could give me an example or two of what sort of situations you tend to run into, I'd be grateful – would be good to know that I'm actually solving the right problem 🙂

2. Not Wireframe specifically, but I did build a few rather large sites with pw-mvc and RepeaterMatrix. In those cases I ended up using field templates (/site/templates/fields/) for the bulk of the RepeaterMatrix stuff. Worked quite nicely, really. I'll add a note to write a bit about this to the "Patterns and practices" page.

This is just a rough idea, not sure if it's going to go anywhere but I'm actually wondering if I should extend the $partials object a bit?

Currently it's actually a bit silly – basically an "object oriented" way to replace <?php include 'partials/menu/top.php' ?> with <?php include $partials->menu->top ?>. If each property could be used as a function, this would allow us to pass the partial arguments: <?= $partials->menu->meta([ 'description' => 'some text' ]) ?>, etc. Or we could pass in a string, in which case a Controller method would be used to pass the data to the partial.

Again, just thinking out loud here. Not sure if this makes any sense, but I'm kind of liking the idea 🙂

Another idea I've been toying with would be subcontrollers (or child controllers, or partial controllers, or whatever terminology makes most sense). These could solve situations where you end up needing the same stuff from template to template. You can always create custom base controllers and extend them, but this might allow for easier composition.

As MVC is about separation of concerns, as you said a number of times yourself, @teppo, I think render functions are not so good here. Because a html/css is mixed too much with php. Logic and presentation together again)

I was talking about something like described here, with dedicated controller and view.

I looked through recent projects for examples of those partials. These are common ones:

  • menus;
  • breadcrumbs;
  • sidebar;
  • repeating forms (any repeating elements really, anything like wordpress widgets / joomla modules).

I get your point, and agree – to a point. When I first came across the idea of render functions (with that specific name it was some bit of code from Ryan I believe), this was exactly what I thought 🙂

Since then I've used render-functions in numerous projects, and while in some cases it still feels a bit "dirty", in real world it can be a tremendously helpful strategy and hasn't really caused me any notable headaches so far – quite the opposite. These days I don't have a major issue with code that generates markup as long as it's clearly separated into its own container, i.e. "siloed" properly. While I don't encourage mixing business logic with presentation, this is one of those cases where the line is a bit blurry.

Also, as a minor note I don't think that we should separate logic and presentation based on the language alone. PHP can be used to create "presentational" content, so overall it's more about what you do than how you do it. Something like Twig is supposed to be "purely presentational", but you wouldn't believe the complexity of some of the logic I've seen implemented in/with it. (But this is a topic for another discussion – templating languages vs. using PHP as a templating language, and so on and so forth.)

1 hour ago, Ivan Gretsky said:

Awesome! As far as I can tell this is actually really close to this rough idea I mentioned earlier – or, more precisely, it would be one possible use case for (or variation of) it:

Another idea I've been toying with would be subcontrollers (or child controllers, or partial controllers, or whatever terminology makes most sense)

I'm not entirely sure if it actually needs to be a separate concept ("chunks", or whatever that would be called), but that's not necessarily a bad idea, if it makes the concept easier to grasp. Technically it should already be possible to instantiate a new Controller, provide it with a View file, and then render the output within, say, another Controller. That's what Wireframe itself does for the page, though it all happens automatically.

Another thing that might not be obvious yet (I'll have to check the docs relating to this) is that there are two use cases for views:

  1. They provide alternative ways to render a Page. For an example the default view might render markup (HTML) for the entire page, and another might render an RSS feed for a list of news items.
  2. They can be used to populate View Placeholders: if you request <?= $placeholders->aside ?> in a layout file used for the "home" template and add a view file at views/home/aside.php, Wireframe will automatically populate the "aside" placeholder with the content of current page rendered with that view file.

Anyway, I'll definitely dig into this topic a bit more and come back with some sort of solution, hopefully – thanks for linking to the TemplateEngineFactory example 🙂

  • menus;
  • breadcrumbs;
  • sidebar;
  • repeating forms (any repeating elements really, anything like wordpress widgets / joomla modules).

Thanks – this list was quite helpful. For the record, here's how I've handled these examples in my past projects:

  • For menus I've used MarkupSimpleNavigation, and later MarkupMenu. In the boilerplate profile I do have partials for these, but they just call the render function of a markup module.
  • Breadcrumbs is in my case usually a simple list of parents, thus I've used a "dumb" partial file with a foreach loop. Here's an example.
  • Sidebar, again, tends to be either a single RTE field (something like sidebar, aside, or perhaps right_column or left_column), or sometimes a predefined list of multiple fields. Again a valid use case for so-called dumb partial files, but this is actually exactly the use case for which I originally added the ability to use View files as View Placeholders.
  • Repeating elements covers a wide area of different content, but in my projects these have usually meant one of two things:
    • A news list or something similar, with predefined header, list of items, and often some sort of "footer" area as well. These use cases I've usually solved with render functions.
    • Repeater, RepeaterMatrix, or some other repeatable fieldtype. "Dumb" partials with some foreach rules, or native field rendering (particularly useful for RepeaterMatrix).

Note that I'm not saying that your use cases are invalid, or that the list above would be the "correct" way to handle these. It's just that I can see why this hasn't been a notable issue for me – but this also helps me understand the kind of use cases you've run into, and thus figure out how to continue from here on 🙂

I can relate to that. But the thing is I often do not do my html/css/js myself and pretty often people with very little knowledge of php are to make minor changes to view code. That's why I try to have my markup as close to raw html as possible. And render functions are clearly the opposite.

A am with you here. Entities should not be multiplied without necessity)) And that's why I do not quite like the placeholder thing. I think it should be that generic call for controller and view. And in this specific case sidebar usually is not tied to a particular template. So this thing seems "too opinionated" for me) I even think that the whole layout thing can be moved to view folder. I now think it is more clear to keep all the view related stuff in one place (though i did use dedicated layout folder in the past - now it is inside the view folder in my recent projects).

That changes things quite a bit. Personally I've never been a part of this kind of team – as strange as it may sound, I've worked in teams where there are backend developers and so-called full-stack developers, but never a "pure" front-end developer 😅

You've definitely given me something to think about here!

I now think it is more clear to keep all the view related stuff in one place (though i did use dedicated layout folder in the past - now it is inside the view folder in my recent projects).

Features that are not tied to a specific template have in my use cases usually been partials with very little "logic" behind them, but this would actually be a nice use case for shared (sub)controllers as well, which is something I'll likely dive into soon. Basically the idea is to have a controller that isn't tied to a single template, but rather can be used by multiple templates. Also controllers that inherit other controllers – "base controllers", or whatever they might be called – is another way to achieve shared features.

Overall there's a lot you can do with current codebase, but since there are different use cases, it's very much about finding a balance between "not opinionated enough" and "too opinionated" 🙂

As for layouts, I've found the concept really useful, and since I use them in pretty much all projects I work on, this is something I wanted to have built-in and ready-to-use within Wireframe. Placeholders are a key part of this, as they provide an easy way to embed views (of which there may be one or more for each specific template) within commonly shared layouts –aAnd because layouts serve a different purpose from view files (individual views for templates) and partials (smaller pieces of content intended to be embedded within layouts or view files), I've opted to store them separately.

This is again one of those cases where it's all about finding the right balance and figuring out what should be available out of the box and what to leave for individual developers to figure out on their own, and I feel that current split between layouts/views/partials is a reasonable one – but because I know there are different opinions, much of this is actually already configurable. Also, since layouts are optional, one can always opt out from using them 🙂

Thanks for your answers and for you generously shared work, @teppo!

I really like your Wireframe idea - a well-established and documented way to structure code in ProcessWire MVC way. So one could follow rules that are thought out and described. I understand quite well that in order for this to work one should give up some of his own preferences) Will be looking forward to next additions to the project we've been talking about here.

Hey folks – a quick update: Wireframe 0.5.0 was released couple of days ago. Compared to 0.4.x this version mainly fixes bugs and improves performance – nothing particularly major, but if you're using Wireframe, it's a recommended update.

On a loosely related note, Tracy Debugger has been really helpful in figuring things out, identifying bottlenecks, etc. Brilliant module 🙂

      I wanted to let you know that I am currently working on a new ProcessWire module that fully integrates the Snipcart Shopping Cart System into ProcessWire. (this is a customer project, so I had to postpone the development of my other module GroupMailer).
      The new module SnipWire offers full integration of the Snipcart Shopping Cart System into ProcessWire.
      Here are some highlights:
      simple setup with (optional) pre-installed templates, product fields, sample products (quasi a complete shop system to get started immediately) store dashboard with all data from the snipcart system (no change to the snipcart dashboard itself required) Integrated REST API for controlling and querying snipcart data webhooks to trigger events from Snipcart (new order, new customer, etc.) multi currency support self-defined/configurable tax rates etc. Development is already well advanced and I plan to release the module in the next 2-3 months.
      I'm not sure yet if this will be a "Pro" module or if it will be made available for free.
      I would be grateful for suggestions and hints!
      (please have a look at the screenshots to get an idea what I'm talking about)

      Update 31.7.2019: AdminBar is now maintained by @teppo. Modules directory entry has been updated, as well as the "grab the code" link below.
      ***
      Latest screencast: http://www.screencas...73-ab3ba1fea30c
      Grab the code: https://github.com/teppokoivula/AdminBar
      ***
      I put this Adminbar thingy (from here: http://processwire.c...topic,50.0.html) to modules section and to it's own topic.
      I recorded quick and messy screencast (really, my first screencast ever) to show what I have made so far. You can see it from here: http://www.screencas...18-1bc0d49841b4
      When the modal goes off, I click on the "dark side". I make it so fast on screencast, so it might seem a little bit confusing. Current way is, that you can edit, go back to see the site (without saving anything), continue editing and save. After that you still have the edit window, but if you click "dark side" after saving, then the whole page will be reloaded and you see new edits live.
      I am not sure if that is best way: there are some strengths in this thinking, but it is probably better that after saving there shouldn't be a possibility to continue editing. It might confuse because then if you make edits, click on dark side -> *page refresh* -> You lose your edits.
      ***
      When I get my "starting module" from Ryan, I will turn this into real module. Now I had to make some little tweaks to ProcessPageEdit.module (to keep modal after form submits). These probably won't hurt anything:
      if($this->redirectUrl) $this->session->redirect($this->redirectUrl); if(!empty($_GET['modal'])) $this->session->redirect("./?id={$this->page->id}&modal=true"); // NEW LINE else $this->session->redirect("./?id={$this->page->id}");   and...
      if(!empty($_GET['modal'])) { $form->attr('action', './?id=' . $this->id . '&modal=true'); } else { $form->attr('action', './?id=' . $this->id); // OLD LINE }

      Jumplinks for ProcessWire
      Release: 1.5.54
      Composer: rockett/jumplinks
      Jumplinks is an enhanced version of the original ProcessRedirects by Antti Peisa.
      The Process module manages your permanent and temporary redirects (we'll call these "jumplinks" from now on, unless in reference to redirects from another module), useful for when you're migrating over to ProcessWire from another system/platform. Each jumplink supports wildcards, shortening the time needed to create them.
      Unlike similar modules for other platforms, wildcards in Jumplinks are much easier to work with, as Regular Expressions are not fully exposed. Instead, parameters wrapped in curly braces are used - these are described in the documentation.
      Under Development: 2.0, to be powered by FastRoute
      As of version 1.5.0, Jumplinks requires at least ProcessWire 2.6.1 to run.
      View on GitLab
      Download via the Modules Directory
      Read the docs
      Features
      The most prominent features include:
      Basic jumplinks (from one fixed route to another) Parameter-based wildcards with "Smart" equivalents Mapping Collections (for converting ID-based routes to their named-equivalents without the need to create multiple jumplinks) Destination Selectors (for finding and redirecting to pages containing legacy location information) Timed Activation (activate and/or deactivate jumplinks at specific times) 404-Monitor (for creating jumplinks based on 404 hits) Additionally, the following features may come in handy:
      Stale jumplink management Legacy domain support for slow migrations An importer (from CSV or ProcessRedirects) Feedback & Feature Requests
      I’d love to know what you think of this module. Please provide some feedback on the module as a whole, or even regarding smaller things that make it whole. Also, please feel free to submit feature requests and their use-cases.
      Note: Features requested so far have been added to the to-do list, and will be added to 2.0, and not the current dev/master branches.
      Open Source

      Jumplinks is an open-source project, and is free to use. In fact, Jumplinks will always be open-source, and will always remain free to use. Forever. If you would like to support the development of Jumplinks, please consider making a small donation via PayPal.
      Enjoy! :)

      I've spent the last while experimenting with srcset implementation - and PageimageSrcset is the result:
      PageimageSrcset
      Provides configurable srcset and sizes properties/methods for Pageimage.
      Overview
      The main purpose of this module is to make srcset implementation as simple as possible in your template code. It does not handle images rendered in CKEditor or similar fields.
      For an introduction to srcset and sizes, please read this Mozilla article about responsive images.
      Pageimage::srcset()
      // The property, which uses the set rules in the module configuration $srcset = $image->srcset; // A method call, using a set rules string // Delimiting with a newline (\n) would also work, but not as readable $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x"); // The same as above but using an indexed/sequential array $srcset = $image->srcset([ "320", "480", "640x480 768w", "1240", "2048 2x", ]); // The same as above but using an associative array // No rule checking is performed $srcset = $image->srcset([ "320w" => [320], "480w" => [480], "768w" => [640, 480], "1240w" => [1240], "2x" => [2048], ]); // Use the default set rules with portrait images generated for mobile/tablet devices $srcset = $image->srcset(true); // Return the srcset using all arguments $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x", [ "portrait" => "320, 640", ]); // The set rules above are a demonstration, not a recommendation! Image variations are only created for set rules which require a smaller image than the Pageimage itself. On large sites this may still result in a lot of images being generated. If you have limited storage, please use this module wisely.
      Portrait Mode
      In many situations, the ratio of the image does not need to change at different screen sizes. However, images that cover the entire viewport are an exception to this and are often the ones that benefit most from srcset implementation.
      The main problem with cover images is that they need to display landscape on desktop devices and portrait when this orientation is used on mobile and tablet devices.
      You can automatically generate portrait images by enabling portrait mode. It is recommended that you use this in combination with Pageimage::focus() so that the portrait variations retain the correct subject.
      The generated variations are HiDPI/Retina versions. Their height is determined by the portrait ratio (e.g. 9:16). Variations are always generated, regardless of whether the original image is smaller. Upscaling is disabled though, so you may find that some variations are actually smaller than they say they are in their filename.
      The sizes attribute should be used when portrait mode is enabled. Pageimage::sizes will return (orientation: portrait) and (max-width: {maxWidth}px) 50vw by default, which handles the use of these images for retina devices. The maximum width used in this rule is the largest set width.
      Pageimage::sizes()
      There is no option to configure default sizes because in most cases 100vw is all you need, and you do not need to output this anyway as it is inferred when using the srcset attribute. You can use the method for custom sizes though:
      // The property $sizes = $image->sizes; // Returns 100vw in most cases // Returns '(orientation: portrait) and (max-width: {maxWidth}px)50vw' if portrait mode enabled // A method call, using a mixture of integer widths and media query rules // Integer widths are treated as a min-width media query rule $sizes = $image->sizes([ 480 => 50, "(orientation: portrait) and (max-width: 640px)" => 100, 960 => 25, ]); // (min-width: 480px) 50vw, (orientation: portrait) and (max-width: 640px) 100vw, (min-width: 960px) 25vw // Determine widths by UIkit 'child-width' classes $sizes = $image->sizes([ "uk-child-width-1-2@s", "uk-child-width-1-3@l", ]); // (min-width: 640px) 50vw, (min-width: 1200px) 33.33vw // Determine widths by UIkit 'width' classes $sizes = $image->sizes([ "uk-width-1-2@m", "uk-width-1-3@xl", ]); // (min-width: 960px) 50vw, (min-width: 1600px) 33.33vw // Return the portrait size rule $sizes = $image->sizes(true); // (orientation: portrait) and (max-width: {maxWidth}px) 50vw // The arguments above are a demonstration, not a recommendation! Pageimage::render()
      This module extends the options available to this method with:
      srcset: When the module is installed, this will always be added, unless set to false. Any values in the formats described above can be passed. sizes: Only used if specified. Any values in the formats described above can be passed. uk-img: If passed, as either true or as a valid uk-img value, then this attribute will be added. The srcset attribute will also become data-srcset. Please refer to the API Reference for more information about this method.
      // Render an image using the default set rules echo $image->render(); // <img src='image.jpg' alt='' srcset='{default set rules}'> // Render an image using custom set rules echo $image->render(["srcset" => "480, 1240x640"]); // <img src='image.jpg' alt='' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w'> // Render an image using custom set rules and sizes // Also use the `markup` argument echo $image->render("<img class='image' src='{url}' alt='Image'>", [ "srcset" => "480, 1240", "sizes" => [1240 => 50], ]); // <img class='image' src='image.jpg' alt='Image' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 1240px) 50vw'> // Render an image using custom set rules and sizes // Enable uk-img echo $image->render([ "srcset" => "480, 1240", "sizes" => ["uk-child-width-1-2@m"], "uk-img" => true, ]); // <img src='image.jpg' alt='' data-uk-img data-srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 960px) 50vw'> // Render an image using portrait mode // Default rule sets used: 320, 640, 768, 1024, 1366, 1600 // Portrait widths used: 320, 640, 768 // Original image is 1000px wide // Not possible to use portrait mode and custom sets or portrait widths in render() // Sizes attribute automatically added echo $image->render(["srcset" => true]); // <img src='image.jpg' alt='' srcset='image.320x569-srcset-hidpi.jpg 320w, image.640x1138-srcset-hidpi.jpg 640w, image.768x1365-srcset-hidpi.jpg 768w, image.jpg 1024w' sizes='(orientation: portrait) and (max-width: 768px) 50vw'> Configuration
      To configure this module, go to Modules > Configure > PageimageSrcset.
      Set Rules
      These are the default set rules that will be used when none are specified, e.g. when calling the property: $image->srcset.
      Each set rule should be entered on a new line, in the format {width}x{height} {inherentwidth}w|{resolution}x.
      Not all arguments are required - you will probably find that specifying the width is sufficient for most cases. Here's a few examples of valid set rules and the sets they generate:
      Set Rule Set Generated Arguments Used 320 image.320x0-srcset.jpg 320w {width} 480x540 image.480x540-srcset.jpg 480w {width}x{height} 640x480 768w image.640x480-srcset.jpg 768w {width}x{height} {inherentwidth}w 2048 2x image.2048x0-srcset.jpg 2x {width} {resolution}x How you configure your rules is dependent on the needs of the site you are developing; there are no prescriptive rules that will meet the needs of most situations. This article gives a good overview of some of the things to consider.
      When you save your rules, a preview of the sets generated and an equivalent method call will be displayed to the right. Invalid rules will not be used, and you will be notified of this.
      Portrait Mode
      Set Widths
      A comma limited list of widths to create HiDPI/Retina portrait variations for.
      Crop Ratio
      The portrait ratio that should be used to crop the image. The default of 9:16 should be fine for most circumstances as this is the standard portrait ratio of most devices. However, you can specify something different if you want. If you add a landscape ratio, it will be switched to portrait when used.
      Any crops in the set rules ({width}x{height}) are ignored for portrait mode variations as this ratio is used instead.
      UIkit Widths
      If your website theme uses UIkit, you can pass an array of UIkit width classes to Pageimage::sizes to be converted to sizes. The values stored here are used to do this. If you have customised the breakpoints on your theme, you should also customise them here.
      Please note that only 1- widths are evaluated by Pageimage::sizes, e.g. uk-width-2-3 will not work.
      Remove Variations
      If checked, the image variations generated by this module are cleared on Submit. On large sites, this may take a while. It makes sense to run this after you have made changes to the set rules.
      Image Suffix
      You will see this field when Remove Variations is checked. The value is appended to the name of the images generated by this module and is used to identify variations. You should not encounter any issues with the default suffix, but if you find that it conflicts with any other functionality on your site, you can set a custom suffix instead.
      Debug Mode
      When this is enabled, a range of information is logged to pageimage-srcset.
      PageimageSrcsetDebug.js is also added to the <head> of your HTML pages. This will console.log a range of information about the images and nodes using srcset on your page after a window.onresize event is triggered. This can assist you in debugging your implementation.
      The browser will always use the highest resolution image it has loaded or has cached. You may need to disable browser caching to determine whether your set rules are working, and it makes sense to work from a small screen size and up. If you do it the other way, the browser is going to continue to use the higher resolution image it loaded first.
      UIkit Features
      This module implements some additional features that are tailored towards UIkit being used as the front-end theme framework, but this is not required to use the module.
      Installation
      Download the zip file at Github or clone the repo into your site/modules directory. If you downloaded the zip file, extract it in your sites/modules directory. In your admin, go to Modules > Refresh, then Modules > New, then click on the Install button for this module. ProcessWire >= 3.0.123 is required to use this module.
