    I maybe be wrong but it seems, you want to render a certain info based on the data provided, ideally most Table give options to enable you have power over the rendering process. Does this satisfy your feat, and also it's like a plugin too https://www.ag-grid.com/javascript-grid-cell-rendering-components/

    Twig doesn't know what a field is, all it expects are variables which are passed to the twig templates from the processwire php files based on the Twig module. Let's take for example the side template in twig, I can have an array of posts which will render the post in a list manner. All I simply need to do is get a list of post and set it with a variable name for that template and the twig template simply renders it based on the variable passed. Besides at the end of the day Twig is basically still compiles to php so it's nothing unique just another layer.

    I just looked at Latte and it's very clean to read, it looks so similar to Twig, I was using Smarty before but Twig is 100% OOP and extending it is cleaner compared to Smarty, I will give Natte Latte a shot later on.

    "delayed output strategy" to me is the same as concatenation, it easily gets messy, hard and difficult to follow, not exactly easy to inherit templates or layouts. It might work but it comes at the cost of readability and how easy it is in making mistakes. Twig Template makes it easier to read ,the only disadvantage I can bring up is that, you cannot instantiate a class inside the template, you must pass a reference of an object to it, then again, your template must not be tied to a code, it should simply take a value it expects and evaluate from that. It makes things really easy to read. As for performance it compiles down to php templates, it only compiles when the source has been changed.

    I understand what you mean, I had the opportunity to rewrite an existing application to Processwire, that was going to be alot of work plus the site works fine already, as I know my way around WordPress Development, sometimes some decisions are not technical just business sense.

    Hi, So today I will writing a small tutorial on developing templates in Processwire using Twig Template, Processwire is a highly flexible CMS which gives developers/designers/users options and allows easy extension of the platform. So here goes the tutorial What is Twig Template ? Simply put in my own words, Twig is a modern templating engine that compiles down to PHP code, unlike PHP, Twig is clean on the eyes , flexible and also quite *easy* to have dynamic layout site with ease ,without pulling your hair out. Twig is trusted by various platforms. It was created by the guys behind Symfony. Take this code as an example {% for user in users %} <h1>* {{ user }}</h1> {% endfor %} This will simply be the equivalent in PHP World <?php $userArray = ["Nigeria","Russia"]; foreach($userArray as $user): ?> <h1><?= $user ?></h1> <?php endforeach; The PHP code though looks simple enough however, you start to notice that you have to be concerned about the PHP tags by ensuring they are closed properly , most times projects gets bigger and comes complex and harder to read/grasp, and also in PHP you can explicitly create variables in the template making it very hard to read as it grows and prone to getting messy WordPress is a major culprit when it comes to that regard. Have you ever wanted to created separate layouts for different pages and break your sites into different parts e.g Sidebar, Comment Section, Header Section ? the regular approach would be to create individual pages for each section and simply add them as templates for the pages and with time, you can end up having tons of templates, however Twig allows you to easily inherit templates and also override the templates where you can inject content into the block easily. Don't worry if you don't understand the concept, the following parts will explain with an example of how to easily inherit layouts and templates. Layout <!DOCTYPE html> <html lang="en"> <head> {{include("layout/elements/header.twig")}} </head> <body> <div class="container-fluid" id="minimal"> <header id="pageIntro"> <div class="bio_panel"> <div class="bio_section col-md-6"> <h1>Okeowo Aderemi</h1> <h2>{{ page.body }}</h2> </div> </div> <div class="clearfix"></div> </header> <section id="page-body"> <div class="container"> <div id="intro" class="col-md-7 col-lg-7"> <h1>About me</h1> <h2> {{ page.summary }} </h2> </div> {block name="content"}{/block} <a style="font-size:1.799783em; font-style:italic;color:#d29c23" href="{{pages.get('/notes').url }}">Read more articles</a> </div> <div class="clearfix"></div> </div> </section> </div> <footer> <div class="header-container headroom headroom--not-top headroom--pinned" id="header-container"> {{include("layout/elements/footer.twig")}} </div> </footer> </body> </html> This is basically a layout where we specify blocks and include other templates for the page, don't panic if you don't understand what is going on, I will simply break down the weird part as follows: Include This basically is similar to native PHP 'include', as it's name suggests it simply includes the templates and injects the content into the layout , nothing out of the ordinary here if you are already familiar with php's include function. {{ output }} This simply evaluates the expression and prints the value, this evaluate expressions, functions that return contents , in my own short words it's basically the same as <?= output ?> except for the fact that it's cleaner to read. {% expression %} unlike the previous this executes statements such as for loops and other Twig statements. {% for characters in attack_on_titans %} <h1> {{characters}} </h1> {% endfor %} This executes a for loop and within the for loop, it creates a context to which variables in that context can be referenced and evaluated, unlike dealing with the opening and closing PHP tags, Twig simply blends in with markup and makes it really quick to read. I will simply post the contents of both the header and footer so you can see the content of what is included in the layout header.php <meta charset="utf-8"/> <meta content="IE=edge" http-equiv="X-UA-Compatible"/> <meta content="width=device-width, initial-scale=1" name="viewport"/> <title> {{ page.title }} </title> <link href=" {{config.urls.templates }}assets/css/bootstrap.min.css" rel="stylesheet"/> <link href="{{config.urls.templates }}assets/css/main.min.css" rel="stylesheet"/> <link rel='stylesheet' type='text/css' href='{{config.urls.FieldtypeComments}}comments.css' /> <link rel="stylesheet" href="{{config.urls.siteModules}}InputfieldCKEditor/plugins/codesnippet/lib/highlight/styles/vs.css"> <script type="text/javascript" src="{{config.urls.siteModules}}InputfieldCKEditor/plugins/codesnippet/lib/highlight/highlight.pack.js"></script> <script src="{{config.urls.templates }}assets/js/vendors/jquery-1.11.3.min.js"> </script> <script src="{{config.urls.templates }}assets/js/vendors/bootstrap.min.js"> </script> <script src="{{config.urls.FieldtypeComments}}comments.js"></script> <link rel="stylesheet" type='text/css' href="{{config.urls.templates}}js/jquery.fancybox.min.css"> <script src="{{config.urls.templates}}js/jquery.fancybox.min.js"></script> {block name="javascriptcodes"}{/block} footer.php <nav class="site-nav pull-right"> <div class="trigger"> <a class="page-link" href="{{pages.get('/about').url}}"> <span>{</span> About <span>}</span> </a> <a class="page-link" href="{{pages.get('/notes').url}}"> <span>{</span> Journals <span>}</span> </a> <a class="page-link" target="_blank" href="https://ng.linkedin.com/in/okeowo-aderemi-82b75730"> <span>{</span> Linkedin <span>}</span> </a> <a class="twitter page-link" target="_blank" href="https://twitter.com/qtguru"> <span>{</span> Twitter <span>}</span> </a> </div> </nav> There's nothing special here, other than twig simply injecting these fragments into the main layout , the next part is the most interesting and important concept and benefit that Twig has to offer {% block content %}{% endblock %} This tag simply creates a placeholder in which the content would be provided by the template inheriting this layout, in lay terms it simply means child templates will provide content for that block, the 'content' simply uses the name 'content' to refer to that specific block, so assuming we were to inherit this template it would simply look like this. Inheriting Template Layout {% extends 'layout/blog.twig' %} {% block content %} <div class="container blog-container"> <section class="blog"> <header class="blog-header"> <h1> {{page.title}} </h1> <h5 class="blog_date"> {{page.published|date("F d, Y")}} </h5> <br> </br> </header> <div class="blog_content"> <hr class="small" /> {{page.body}} <hr class="small" /> </div> </section> </div> {% endblock %} {% block nav %} <div class="col-md-4 col-xs-4 col-sm-4 prev-nav"> <a href="{{page.prev.url}}"> ← Prev </a> </div> <div class="col-md-4 col-xs-4 col-sm-4 home-nav"> <a href="{{homepage.url}}"> Home </a> </div> <div class="col-md-4 col-xs-4 col-sm-4 next-nav"> <a href="{{page.next.url}}"> Next → </a> </div> {% endblock %} In this snippet you can easily notice how each blocks previously created in the header and layout are simply referenced by their names, by now you will notice that twig doesn't care how you arrange the order of each block, all Twig does is to get the contents for each blocks in the child templates and inject them in the layout theme, this allows flexible templating and also extending other layouts with ease. Twig in Processwire Thanks to @Wanze we have a Twig Module for Processwire and it's currently what i use to build PW solutions to clients https://modules.processwire.com/modules/template-engine-twig/ The Modules makes it easy to not only use Twig in PW but also specify folders to which it reads the twig templates, and also injects Processwire objects into it, which is why i can easily make reference to the Pages object, another useful feature in this module is that you can use your existing template files to serve as the data provider which will supply the data to be used for twig template. take for example, assuming I wanted the homepage to display the top six blog posts on it, TemplateEngineTwig will simply load the home.php ( Depending on what you set as the template), it is also important that your twig file bears the same name as your template name e.g home.php will render into home.twig here is an example to further explain my point. home.php <?php //Get the Top 6 Blog Posts $found=$pages->find("limit=6,include=hidden,template=blog-post,sort=-blog_date"); $view->set("posts",$found); The $view variable is the TemplateEngine which in this case would be Twig, the set method simply creates a variables posts which holds the data of the blog posts, the method allows our template 'blog.twig' to simply reference the 'posts' variable in Twig Context. Here is the content of the 'blog.twig' template blog.tpl {% extends 'layout/blog.twig' %} {% block content %} <div class="block_articles col-md-5 col-lg-5"> {% for post in posts %} <div class="article_listing"> <span class="article_date"> {{post.published}}</span> <h2 class="article_title"> <a href="{{post.url}}">{{post.title}}</a> </h2> </div> {% endfor %} {% endblock %} So home.php sets the data to be used in home.tpl once Twig processes the templates and generates the output, twig takes the output from the block and injects it in the appriopriate block in the layout, this makes Processwire templating more flexible and fun to work with. The major advantage this has; is that you can easily inherit layouts and provide contents for them with ease, without the need of running into confusions when handling complex layout issues,an example could be providing an administrator dashboard for users on the template side without allowing users into the Processwire back-end. You can also come up with several layouts and reusable templates. Feel free to ask questions and any concerns in this approach or any errors I might have made or overlooked. Thanks

    The correct word is all times, I haven't come across any site builder that allows 100% control over content without creating a mess or even without the need for code, the closest so far I can think of is October CMS which generates a templates from the frontend and allows you to tweak them, but it requires knowledge of Twig or blade (not sure), really this is an important topic you raised, I have a client i tried convincing to try Processwire, but the client wasn't interested in coding and wanted to builder to achieve all their needs. The only thing i can think of is a Builder 100% built around Processwire API(s) meaning, when they create a Page and add content and use modules from builder, at the backend it should replicate the same process like creating a template, downloading the modules but that will be a very difficult task to achieve. However I would be happy to hear what ideas you have and we can research further upon that. so far Processwire is the best CMS platform that's minimal and straight forward but for developers more. ImpressPages comes close to what you have in mind, I will keep an eye on this thread and contribute should i have more information. If this can be achieved I think we can further push PW to clients and have them replace WordPress, at the same time we should be careful we don't create another WordPress in this ecosystem. what do you think ?
  9. qtguru
    I can't comment about the first because I don't fancy that pattern but the second think about it as a stack by prepending, you're pushing the items from the top when adding compared than from the bottom.
  10. qtguru
    More than enough , thanks alot this is what i needed.

    Net2FTP logs me out everytime, I feel it must be network related haven't tried monsta FTP but i like the having to just edit the file from the same application however it should only edit the modules and templates and not core code.
  12. qtguru
    Am looking at that too, I will fork your project over the weekend and see how I can contribute, am really interested in this, though I have a feeling Monaco feels like overkill, but i will evaluate it and see.
  13. qtguru
    This would be the most useful module for me, because I tend to do my sidejobs at the office after work (I know, it's not proper, commuting issues that's why ) and we have a strong Firewall that blocks FTP and CPanel pages, so this will come real handy, am assuming it has a code-editor in it. thanks a bunch.
  14. qtguru
    Yeah alot of manual work, sometimes it's hard because you need to know which file isn't wordpress specific as it's massive and populated.
  15. qtguru
    It's more expensive and time consuming to rewrite a Project from those to Processwire, and if there's no financial justification no one would, and another point is availability of modules and plugins too.

    The Benefit of Framework is standardized way of working take for example we use Processwire I know if i need to make a DB call i'd use the Processwire DB Class, that already saves us the stress of trying to understand each other's code since there's already a standard and way, now imagine you were to manage a non-framework project you'd find yourself trying to understand the way it works and also how it works. That's way framework come in, and also best practices also

    Hi regardless remember I come from a Third world country,small customers cannot simply afford employing developer of other languages and PHP is quite affordable so far PHP has a market, PHP is still viable and in demand, I was just approaching it on the basis that other compiled language would outperform PHP doesn't mean PHP is irrelevant also I don't have any preference for any language I pick whatever works but i must admit PHP is the only platform that's faster for me to bootstrap and come up with something within a short time. To be frank most companies as long as you know PHP to a certain level and you are willing to learn, companies would employ you, there was a time I wasn't familiar with frameworks till I worked for a company and was given a project, I was given a PHP Book on Advanced PHP Development, However the fastest way to pick up PHP is to look up PHP the Right Way. I would have loved to recommend Symfony Framework, I work for an enterprise organization and we mostly develop in almost any language except PHP but mostly Java Spring Framework and Symfony feels closer to that, Symfony gives so much flexibility and freedom and uses best practice, unlike Laravel, I have issues with the abuse of Static class and some Classes suffer from what I call "God Object", The Eloquent ORM irks me out it has too much logic compared to Doctrine way's of handling data. Here is another good resource for PHP knpuniversity.com, Just take it one day at a time. Exactly
  19. qtguru
    Exactly you've hit the nail with the shortcoming of PHP, it's interpreted every time it needs to be parsed and fed to the Zend Engine meanwhile compiled languages would run much more faster and scale better than PHP, I read the benchmark of a Golang application and I was blown apart normally i'd stick to Spring but the memory consumption is excess, but I haven't come across elixir, might give it a shot
  20. qtguru
    If you are doing Web PHP is still awesome, however if it reaches the point where you are really taking shit load of request, that's when you will branch to faster languages like Golang, For me am still deciding which to commit to still deciding between .NET Core, Spring MVC or Golang Web frameworks but still be using PHP for simple sites.
  21. qtguru
    I have done something like this but this was in Spring Framework and not Processwire, you don't really need fields to do this ( This is my issue with using PW,it's easier for me to translate logic to classes than fields and pages). What i did was to create different Object in Java and created an interface to make things easier so you have your MultiChoice Class, True or False Class, Open End Question class , all i needed to do was return a JSON that had enough meta-data to inform the UI what to render on the frontend and based on the question type it would generate the control to display the question and save the answer to a QuizManager which stores the question id and the answer for each quiz.

    I have heard alot about Django from a mentor, from what I hear it's actually quite a robust solution, so to be honest am a fan of use what's right , I don't subscribe to using Processwire for every type of application most times, I might find myself using Symfony for certain projects because of the flexibility and proper architecture that requires me to handle things and remove certain bundles , but I mostly use Processwire to build sites I want clients to manage, the moment an application has so many custom and specific needs, I would use an application framework, now if I were in Python world, because I don't really like Python i'd use Django for Site management but would prefer to use something light and flexible. Also I think you should state views without insulting, calling people "Fanboy" is not the right approach all the best

    Had no choice than to settle for modifying the TemplateEngineTwig, feels so hackish. If anyone can guide me on how you can hook to the TemplateEngine::initTwig from a template i'd be appreciative, a feature in the future could be a user-defined folder where extensions can be placed and used easily.
  24. qtguru
    I think this is limiting if I can't extend modules from templates and only from modules.
  25. qtguru
    This is strange I can't find myself to hooking TemplateEngineTwig:init no matter what i do nothing happens and in Symfony this is not a problem for me, am I missing anything wire()->addHookAfter("TemplateEngineTwig::initTwig", function($event) { $twig = $event->arguments('twig'); $instanceOfFunction = new Twig_Function('instanceof', function ($object,$evaluatedClass) { return ($object instanceof $evaluatedClass); }); $twig->addFunction($instanceOfFunction); });
