之所以发生这种情况，是因为它不是发布请求. CHtml::link提供了一种使用post方法而不是get的方法.这要求您在clientChange 的submit属性>.

This is happening because it's not a post request. CHtml::link has a way by which you can use post method, instead of get. This requires you to use submit attribute of clientChange, in your htmlOptions.

有点像:

echo CHtml::link(CHtml::encode('Delete image'), array('image/delete', 'id'=>$image->id),
  array(
    'submit'=>array('image/delete', 'id'=>$image->id),
    'class' => 'delete','confirm'=>'This will remove the image. Are you sure?'
  )
);
