Yii URL Manger create a route with multi optional parameters

I have a URL rule with multiple optional parameters and it was working but it stopped after I upgraded from Yii 1.1.15 to 1.1.19.

const OPTIONAL_PARAMS = '(/<featured:featured>)?'
. '(/subType/<subType:.*?>)?'
. '(/type/<type:\d+>)?'
. '(/category/<category:.*>)?';


'<lang:(en|fr)>/reports'. OPTIONAL_PARAMS => 'reports',

Any one can provide me some ideas or someone faced similar issues?

P.S. The other URL manager rules are working fine, only this one with (SOME_CODE)? for optional params is not working. I'm using PHP 5.6 and Apache.

Solution

You may be interested in by this issue. But in short: this syntax (regexp outside of named params) was never officially supported and it was removed as a bugfix in Yii 1.1.17.

The last version which supports this is 1.1.16, but it is really old and I would not recommend using it. You should probably create custom UrlRule and use it instead of CUrlRule for this particular case.

You may also try to add /* at the end of the pattern, like this:

'<lang:(en|fr)>/reports/*' => 'reports',

This will allow to append GET params to URL as /key/value. So this:

$this->createUrl('reports', [
    'type' => 'sometype', 
    'category' => 'somecategory',
    'lang' => 'en',
]);

will create URL like:

/en/reports/type/sometype/category/somecategory
