使用Yii2进行网址管理

Question

I have a problem with Yii2's urlManager. I have an action with url category/index, where I pass ?par=test as param.

I want to create an alias for my url so that when par is not specified the url will be /test, but when it is specified the url should be /test/some-value. Here is my config for now:

       'rules' => [
            [
                'pattern' => 'test',
                'route'   => 'category/index',
            ],
            '<subcats: (val|some-value)>' => 'test/<subcats>',

Answer 1

If you need url like category/index/test/some-value. Use that

'category/index/test/<val:\w+>' => 'category/index'

In controller in method index use that:

public function actionIndex($val){

Yii2 automatically provide parameter $val in action.
