Get a named parameter value from request

Question

Yii's named parameters are available in the template. For example, for the following route configuration:

'post/<post_id:\d+>' => ['template' => 'post-entry'],

The value of post_id in my template for the request post/3 will be 3.

But how can I access it from PHP, for example from the Craft::app -> getRequest() ?

Note: I don't mean queryString parameters. QueryString parameters can be accessed using getParam('paramName').

Answer 1

If you want to explicitly grab them from PHP, this should also work:

$result = Craft::$app->getRequest()->resolve();

From there, you could grab $result[1], which should be an array:

array(
    'variables' => array(
        'post_id' => 3,
    ,
    'template' => 'post-entry',
    'p' => 'post/3',
)

Answer 2

It is passed as a parameter to your function

public function actionView($post_id){
    Craft::dd($post_id);
}

Note: your parameter must have the same name like defined in your route. You can't access it with public function actionView($postId)
