Download the PHP package itcig/sagecontroller without Composer

Controller

WordPress package to enable a controller when using Timber/Twig with Sage 9. This also requires heavy modification of Sage 9 to use.

Installation

Composer:

Please note that Controller is no longer an mu-plugin and is now a Composer theme depedency.

Browse into the Sage theme directory and run;

Requirements:

• PHP >= 7.0

Setup

By default, create folder app/Controllers/ within your theme directory.

Alternatively, you can define a custom path using the filter below within your themes resources/functions.php file;

The controller will autoload PHP files within the above path and its subdirectories.

Usage

Creating a basic Controller:

• Controller files follow the same hierarchy as WordPress.
• Extend the Controller Class— it is recommended that the class name matches the filename.
• Create methods within the Controller Class;
  • Use public function to expose the returned values to the Twig views/s.
  • Use public static function to use the function within your Twig view/s.
  • Use protected function for internal controller methods as only public methods are exposed to the view. You can run them within __construct.
• Return a value from the public methods which will be passed onto the Twig view.
  • Important: The method name is converted to snake case and becomes the variable name in the Twig view.
  • Important: If the same method name is declared twice, the latest instance will override the previous.

Examples:

The following example will expose $images to resources/views/single.twig

app/controllers/Single.php

resources/views/single.twig

Creating Components;

You can also create reusable components and include them in a view using PHP traits.

app/controllers/partials/Images.php

You can now include the Images trait into any view to pass on variable $images;

app/controllers/Single.php

Using Static Methods;

You can use static methods as a pass-thru method that returns content from your controller.

This is useful if you are within the loop and want to return data for each post item individually by passing in a $post_id.

app/controllers/Archive.php

resources/views/archive.php

Inheriting the Tree/Heirarchy;

By default, each Controller overrides its template heirarchy depending on the specificity of the Controller (the same way WordPress templates work).

You can inherit the data from less specific Controllers in the heirarchy by implementing the Tree.

For example, the following app/controllers/Single.php example will inherit methods from app/controllers/Singular.php;

app/controllers/Single.php

If you prefer you can also do this;

You can override a app/Controllers/Singular.php method by declaring the same method name in app/Controllers/Single.php;

Creating Global Properties;

Methods created in app/Controllers/App.php will be inherited by all views and can not be disabled as resources/views/layouts/app.php extends all views.

app/Controllers/App.php

Disable Option;
