我创建了一个CommentManager插件,用于在我的帖子中添加评论。在Posts/view.ctp
文件和评论表单操作中添加评论表单会重定向到CommentManager/Comments/add
。
评论正确保存,但在保存空表单时,没有显示我在CommentsTable
中写入的验证错误消息,并且输入的数据也已从表单中删除。
CommentManager / SRC /控制器/ CommentsController /添加
public function add()
{
$ccomment = $this->Comments->newEntity($this->request->data);
if ($this->request->is('post')) {
$newData = ['post_id' => $this->request->params['pass'][0]];
$ccomment = $this->Comments->patchEntity($ccomment, $newData);
if ($this->Comments->save($ccomment)) {
$this->Flash->success('The comment has been saved.');
return $this->redirect($_SERVER['HTTP_REFERER']);
} else {
$this->Flash->error('The comment could not be saved. Please, try again.');
}
}
$this->set(compact('ccomment'));
return $this->redirect($_SERVER['HTTP_REFERER']);
}
CommentManager / SRC /型号/表/ CommentsTable
public function validationDefault(Validator $validator) {
return $validator
->notEmpty('body', 'Body contents required.')
->notEmpty('email', 'An email is required.')
->add('email', [

],
'message' => 'Enter a valid email.'
]
]);
}

请勿使用空数组调用newEntity()
。而不是
$ccomment = $this->Comments->newEntity($this->request->data);
执行:
$ccomment = $this->Comments->newEntity();
在致patchEntity()
的电话中传递$this->request->data
