README
Define snippet controllers in a similar way to how page controllers work.
How to use it
By default the plugin will try to find controllers in your snippets
directory.
Lets have a look at a example header
snippet.
📁 snippets ├─ 📄 header.controller.php └─ 📄 header.php
// header.controller.php // The return value can be a callback return function ($site) { return [ 'title' => $site->title(), ]; }; // Or you can simply return an array. return [ 'title' => site()->title(), ];
You can also define snippet controllers in a plugin.
Kirby::plugin('superwoman/superplugin', [ 'snippets' => [ // Refer to a file 'header.controller' => __DIR__ . '/snippets/header.controller.php', // Return an array 'header.controller' => [ 'title' => site()->title(), ], // Return a callback 'header.controller' => function ($site) { return [ 'title' => $site->title(), ]; }, ], ]);
Available callback arguments in your controllers
You have access to all variables that are also accessible in the snippet. If you pass additional data to the snippet, you can access it in the controller as well.
Note Since version
2.0.0
and Kirby3.9.6
you can also use variadic arguments.
snippet('header', data: ['title' => 'My Title']) // header.controller.php return function (string $title = 'Default Title', ...$args) { return [ 'title' => $title, ]; };
Note Since version
2.1.0
you can override variables when using a controller callback.
snippet('header', data: ['size' => $page->size()]) // header.controller.php return function (Field|string $size = null) { if ($size instanceof Field) { $size = $size->value(); } $size = match ($size) { 'small' => 'height: 50vh', 'medium' => 'height: 80vh', default => 'height: 100vh', }; return [ 'size' => $size, ]; };
Note Since version
2.2.0
you can prevent a snippet from rendering in a controller callback.
snippet('header', data: ['size' => $page->size()]) // header.controller.php return function (Field|string $size = null) { if (is_null($size)) { snippet_prevent(); } return [ 'size' => $size, ]; };
Naming convention
By default, the plugin searches for controllers by appending .controller
to the snippet name.
You can change the name resolver in the options. Changing the name also affects plugin-defined controllers.
// config.php return [ 'lukaskleinschmidt.snippet-controller' => [ // The default resolver 'name' => fn (string $name) => $name . '.controller', // You might want to store controllers in a separate folder 'name' => fn (string $name) => 'controllers/' . $name, ], ];
