Yii解析Urlmanager链接返回数组

Question

How I can access to array of params, passed to controller Action in View? Basicaly before SEO links was applied there was rules in my View (simplified):

foreach(....){
$_GET['filter']=$value;
$link=$this->createUrl('models/showModels',$_GET);
echo CHtml::link(Yii::t('main',$value),$link);
}

But after applying urlManager $_GET variable become to empty, and for sure such rules set stop to work.

I just discover that with some "magic" method it's done in CLinkPager module, but can't understand how.

In Yii you can get param with the following method:

Yii::app()->request->getParam('param_name');
// for example getParam('filter')
// OR Yii::app()->request->getQuery('$_GET KEY');

In order to merge params to $_GET request:

CMap::mergeArray($_GET, array('filter' => 'value'))

In order to get all params:

Yii::app()->request->getQueryString();

Also, Yii has a powerful method to get Dump that I suggest you to use it:

CVarDumper::dump($_GET,34567,true);
