Cakephp “编辑注释vai模式”对话框不'；我不能正常工作

您正在尝试在if的条件语句部分赋值

如果（$this->Comment->id=$id）

：这是错误的，因为该部分用于检查条件

您的问题的解决方案是：

public function edit($id = null) {
        $user_id=$this->Auth->user('id');
        $comment_fields=$this->Comment->findById($id);
        $comment_id=$comment_fields['Comment']['id'];
        $comment = $this->Comment->findById($id);
        if (!($user_id == $comment_fields['Comment']['user_id'])) {
            $this->Flash->error(__('Unable to edit your post.'));
            return $this->redirect(array('action'=>'../posts/view',$comment_fields['Comment']['foreign_id']));
        }

        if (!$comment) 
        {

            $this->redirect(array('action'=>'../posts/view',$comment_fields['Comment']['foreign_id']));
        }
        if ($this->request->is(array('post', 'put'))) {

            if($this->Comment->id = $id)
            {
                if ($this->Comment->save($this->request->data)) {
                    $this->Flash->success(__('Your Comment has been updated.'));
                    $this->redirect(array('action'=>'../posts/view',$comment_fields['Comment']['foreign_id']));
                }
            }else{
                $this->Flash->error(__('Unable to update your Comment.'));
            }


        }
        if (!$this->request->data) {
            $this->request->data = $comment;
        }
    }

更新时尝试使用

$this->request->data['array_index']['id']=$id

问题是，当我在帖子链接中使用onclick方法时，控制器中的编辑功能不起作用，但当我在编辑页面中使用edit ctp时，该功能立即起作用。我只想通过我的模式对话框编辑我的评论。但编辑后链接不适用于编辑功能。我认为，因此，您应该使用模式形式的操作，如下所示：

 <div id="overlay" onClick="hideDialog()"></div>
 <div id="dialog">
 <h2>Edit Comment <span onClick="hideDialog()">&times;</span></h2>

   <?php echo $this->Form->create('Comment',array('enctype'=>'multipart/form-data'));?>
 <?php echo $this->Form->input('Comment.comment',array('class'=>'form-control'));
  echo $this->Form->end('Save');
  ?>

 </div>
 <script>
 function showDialog() {
 document.getElementById("overlay").style.display = "block";
 document.getElementById("dialog").style.display = "block";
 }
 function hideDialog() {
 document.getElementById("overlay").style.display = "none";
 document.getElementById("dialog").style.display = "none";
 }
 </script>

public function edit($id = null) {
        $user_id=$this->Auth->user('id');
        $comment_fields=$this->Comment->findById($id);
        $comment_id=$comment_fields['Comment']['id'];
        $comment = $this->Comment->findById($id);
        if (!($user_id == $comment_fields['Comment']['user_id'])) {
            $this->Flash->error(__('Unable to edit your post.'));
            return $this->redirect(array('action'=>'../posts/view',$comment_fields['Comment']['foreign_id']));
        }

        if (!$comment) 
        {

            $this->redirect(array('action'=>'../posts/view',$comment_fields['Comment']['foreign_id']));
        }
        if ($this->request->is(array('post', 'put'))) {

            if($this->Comment->id = $id)
            {
                if ($this->Comment->save($this->request->data)) {
                    $this->Flash->success(__('Your Comment has been updated.'));
                    $this->redirect(array('action'=>'../posts/view',$comment_fields['Comment']['foreign_id']));
                }
            }else{
                $this->Flash->error(__('Unable to update your Comment.'));
            }


        }
        if (!$this->request->data) {
            $this->request->data = $comment;
        }
    }

$this->Comment->id = $id;
if ($this->Comment->exists()) {
    if ($this->Comment->save($this->request->data)) {
        $this->Flash->success(__('Your Comment has been updated.'));
        $this>redirect(array('action'=>'../posts/view',$comment_fields['Comment']['foreign_id']));
    }
}
else {
    $this->Flash->error(__('Unable to update your Comment.'));
}
