Below is the code which i used for ajax request
echo CHtml::ajaxLink(CHtml::image(Yii::app()->baseUrl.'/images/document.png'), Yii::app()->createUrl( 'user/region' ),
array( // ajaxOptions
'type' => 'POST',
'data' => array('blogs_id'=>$model->id),
'url'=>Yii::app()->createAbsoluteUrl('companies/blog'),
'update'=>'#city_name',
),array('title'=>'Discussion')
);
But when i click on it, it calls another url like users/region instead of companies/blog.
please help me.
