Routing

← Back to the “Kernel” section

App\Common\Router - lightweight HTTP router: matches the path and method of the request with handler. In the control panel, module routes are declared in their routes.php.

Announcing routes

use App\Common\Router;
use App\Adminx\Notes\Controller;

Router::get('/notes',            array(Controller::class, 'index'));
Router::post('/notes',           array(Controller::class, 'store'));
Router::post('/notes/{id}',      array(Controller::class, 'update'));
Router::post('/notes/{id}/pin',  array(Controller::class, 'togglePin'));
Router::delete('/notes/{id}',    array(Controller::class, 'delete'));

Methods: get, post, put, delete, any - all accept ($pattern, $handler).

Path parameters `{name}`

The fragments in curly braces become named parameters and come to the handler with the first argument - the array $params.

Router::get('/documents/{id}/edit', array(Controller::class, 'edit'));

public function edit(array $params = array())
{
    $id = isset($params['id']) ? (int) $params['id'] : 0;
    // ...
}

Types of handlers

Type	Example
`[class, method]`	`array(Controller::class, 'index')` - most common
`Closure`	`function (array $params) { ... }`
`string`	path to the PHP file (include executes the calling code)

Router::get('/ping', function () { return 'pong'; });

Route groups

group($prefix, callable $fn) is a common prefix for a set of routes.

Router::group('/catalog', function () {
    Router::get('/products',        array(Ctrl::class, 'products'));
    Router::get('/products/{id}',   array(Ctrl::class, 'product'));
});
// → /catalog/products, /catalog/products/{id}

Mapping and override method

Router::match($path = null, $method = null) returns ['handler' => ..., 'params' => [...]] or null. By default takes the path and method from $_SERVER.

_method-override supported: HTML form can send PUT/DELETE/PATCH via POST with hidden field _method.

<form method="post" action="/documents/5">
  <input type="hidden" name="_method" value="DELETE">
</form>

Debugging

Router::routes();   // все зарегистрированные маршруты
Router::reset();    // очистить (в тестах)

In the control panel, the mapping and calling the handler does App\Common\Dispatcher on top Router - the module only needs to declare routes in routes.php.
