Yii CGridView搜索“＆”包含属性

I am using Yii 1.1.15 framework.

I can't search & as a symbol in a attribute (ex. brand_name) in the query string. If I enter & symbol the URL looks like this:

localhost/doctors/brand/?brand[brand_name]=&&brand[brand_status]=

Here the case is brand[brand_name]=&. It does not consider the & and is taken as the next parameter termination, if i just encode that character, it becomes: %26 so the url becomes localhost/doctors/brand/?brand[brand_name]=%26&brand[brand_status]= and it gives the correct result.

But how to encode the yii CGridView filter text data?

Thanks in advance.

CGridView uses GET as the default ajax type and & is the delimiter for http request's GET parameters, so you can't use this character as part of your search string. I think the solution is using POST instead of GET for ajax requests. For changing CGridView ajax parameter from GET to POST, add 'ajaxType' => "POST" to your cgridview options:

 <?php $this->widget('zii.widgets.grid.CGridView', array(
      'id'=>'...',
      'ajaxType' => "POST",
      'dataProvider'=>$model->search(),
      'filter'=>$model,
      'columns'=>array(
         ...
       ),
 )); ?>
