Yii2 - UrlManager and params with hypens

Question

I have the following URLs:

http://test.local/index.php?r=site%2Findex&slug=blog-detail
http://test.local/index.php?r=site%2Findex&slug=blog
http://test.local/

I want to get:

http://test.local/blog
http://test.local/blog-detail
http://test.local/ 

I am sending all requests to SiteController::actionIndex($slug), I am using Basic Application Template.

So far, I have been able to hide index.php and site/index.

'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
    'rules' => [
       '<slug\w+>' => 'site/index',
    ],
]

But it seems \w+ does not match strings with -. Also if slug is empty it should show: http://test.local/.

Answer 1

\w does not match -. You need to use [\w\-] instead. And + requires at least one char in your case. You should use * instead:

'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
    'rules' => [
       '<slug:[\w\-]*>' => 'site/index',
    ],
]

Answer 2

What you are trying to make is make specific url based on GET param. With the following example if the user enters url test.local/Some-nice-article then the SiteController::actionIndex($slug) function will get the param.

'urlManager' => [
            'pattern' => '<slug>',
            'route' =>'site/index',
            'ecnodeParams' => false,
            //class => any\custom\UrlRuleClass,
            //defaults => [] 
        ]

Or you want another url to specify whether it is detailed view? You can do it this way:

  'urlManager' => [
                'pattern' => '<slug>-detail',
                'route' =>'site/detail',
                'ecnodeParams' => false,
                //class => any\custom\UrlRuleClass,
                //defaults => [] 
            ]

In this example, if the users puts the string '-detail' at the of the slug, then it will parse the route SiteController::actionDetail($slug) to the request.

Please note that if you did not yet, enable prettyUrls in the config file
