yii2 url rule with named parameter of type array

Question

how can i create an url rule, with a named parameter of type array?

now i have this, working:

    'urlManager' => [
        'rules' => [
            'page/<id:\w+>' => 'cms/page/view',
        ],
    ],

to map 'page/welcome' to module=cms, controller=page, action=view, param $id=welcome

now i would like to have the url like this, with a variable number of folder-name parts: /page/folder1/folder2/.../folderN/pagefile

for an action:

function actionPage(array $folders, string $id) {
    // expecting:
    //   $folders == [ 'folder1', 'folder2', ..., 'folderN']
    //   $id      == 'pagefile'
}

don't know how to write the rule. i couldn't find any documentation for the rule-syntax.

workarounds are welcome, too!

Can you try to rephrase the question, maybe break it up and concentrate on the first case you want to solve? — dataskills

As far as I know the arguments passed to a controller action must be string or int because the controller action parameters work on simple GET parameters.

If you really want to pass an array of folders in a GET request it should be after the route, like: controller/action/id?folder[]=folder1name&folder[]=folder2name

So $id would be in scope in the controller action but you would have to "manually" go through $_GET['folder'] to fetch the variable number of folders that are in the query string.

i saw some custom implementations of "urlRule" and was hoping to get one working with arrays. can you point me to the documentation of the urlRule syntax?

Sure, the URL Rule syntax is here: yiiframework.com/doc-2.0/guide-runtime-routing.html#url-rules
