title: Yii search from function
body: <p>I have a CGridView and I want to search in it. The thing is that I have a column that is modified by a function in my model. Everything start in the search.php view that contains a cgridview that looks like this:</p>
  
  <pre><code>$this-&gt;widget('zii.widgets.grid.CGridView', array(
  'id'=&gt;'grid-demande',
  'summaryText'=&gt;'',
  'dataProvider'=&gt;$model-&gt;search(),
  //'filter'=&gt;$model,
  'cssFile'=&gt;Yii::app()-&gt;request-&gt;baseUrl."/css/my_gridview.css",
  'columns'=&gt;array
  (
  array(            
          'name'=&gt;'id_post',
          'htmlOptions'=&gt;array('width'=&gt;'16%'),
      ),
  array(            
          'name'=&gt;'fk_authorid',
          'htmlOptions'=&gt;array('width'=&gt;'16%'),
          'value'=&gt;array($this,'renderNameDmd'),
      ),
  )
  </code></pre>
  
  <p>As you can see the function renderNameDmd is called to render the name of the author. This function is in my model but is called from the controller:</p>
  
  <pre><code>protected function renderNameDmd($data,$row)
  {
  $model=$this-&gt;loadModelDmd($data-&gt;id_post);
  return $model-&gt;getChAuthor();   
  }
  </code></pre>
  
  <p>And in the model class I call:</p>
  
  <pre><code>public function getChAuthor(){ 
      $modelUsr=TUsers::model()-&gt;findByPk($this-&gt;fk_authorid);
  return $this-&gt;fk_authorid.', '.$modelUsr-&gt;ch_completeName;
  }
  </code></pre>
  
  <p>Everything works fine for displaying. My main problem is that I want to search through this cgridview and I can't search with the values that are displayed. Here is my search function that is contained in my model:</p>
  
  <pre><code>public function search()
  {
      // Warning: Please modify the following code to remove attributes that
      // should not be searched.
  
      $criteria=new CDbCriteria;
  
              //more criterias
  
      $criteria-&gt;compare('fk_cip',$this-&gt;fk_cip,true);
  
      return new CActiveDataProvider($this, array(
          'criteria'=&gt;$criteria,
      ));
  }
  </code></pre>
  
  <p>For the moment, I have tried a couple of things but nothing worked so I reseted the code to what it was initialy. For now, if I search through my cgridview I can only filter with the <em>authorid</em> and not the full column format I wrote. Exemple:</p>
  
  <p>For a row that looks like this:</p>
  
  <blockquote>
    <p>3231, John Doe</p>
  </blockquote>
  
  <p>I can only search through the:</p>
  
  <blockquote>
    <p>3231</p>
  </blockquote>
  
  <hr>
  
  <p>I want to search through the row I created from the function. 
  Thank you for your help!</p>
