Controllers

• Read the guide

Controllers are registered with the controllers extension.

Callback definition

The controllers extension accepts an array of controllers where the key is the name of the associated template and the value a callback function that returns an array of variables for your template.

/site/plugins/your-plugin/index.php

Kirby::plugin('your/plugin', [
    'controllers' => [
        'blog' => function ($page) {
            return [
                'articles' => $page->children()->listed()
            ];
        }
    ]
]);

You can now use the $articles variable in your blog template.

File definition

Alternatively, you can require a file. The required file would be a controller with a function that returns an array of variables for your template.

Kirby::plugin('your/plugin', [
    'controllers' => [
        'blog' => require 'some/file.php'
    ]
]);

Usage in templates

You can directly use the defined variables in the related template.

/site/templates/blog.php

Number of articles: <?= $articles->count() ?>
