Yii Parsing Urlmanager Link Back To Array

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.

array elements are always accessed by using key. you have done in it your code. by using $_GET['filter'] you are accessing the value of key "filter" in your get array. — Rafay Zia Mir
Have you checked before using $_GET in createUrl that it is not empty? — Rafay Zia Mir
As soon as UrlManager rules appliet the "old" urls like aaa.com/show?brand=BMW become to new SEO friendly: aaa.com/BMW Due this reason $_GET always emty and "parsed" variables are stored somewhere else. Now I trying to findout where it's stored and how I can access it. — Val KH

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);
