如何检查控制器中的特定字段值

Question

我有评论功能，评论表中有“状态”字段 ..我想检查这个特定字段值是否等于 0 或者不在控制器中......请有人帮助我更正此代码

   function admin_publish ($id = null){
                  if (!$id) {
                        // set flash message
                        $this->Session->setFlash('Invalid id for Location','default',
array('class' => 'flash_bad'));
                        // redirect
                        $this->redirect(array('action'=>'admin_index'));
                }else{
               // if comment status field 0
        if($comments['Comment']['status']== null){
                // change status from 0 to 1
             $this->Comment->saveField('status',1);
                        // set flash message
                        $this->Session->setFlash('The Comment was successfully
Published.');
                } else {
                     $this->Comment->saveField('status', 0);
                        // set flash message
                        $this->Session->setFlash('The Comment could not be NotPublished.');
                }

                // redirect
                $this->redirect(array('action'=>'admin_index'));
        }
        }

尝试：

$commentData = $this->Comment->findById($commentId, "Comment.status");
$commentStatus = $commentData["Comment"]["Status"];
if(empty($commentStatus)) {
   //its zero
}
else {
  //its not zero
}
