Question

我一直在学习如何使用CakePHP使用视频教程系列，而且我在表单上验证方面存在问题。我已经尝试了几个我在CakePHP书上找到的不同的东西，它似乎也没有用。这是非常简单的验证，只是确保标题不为空或重复，并且帖子不为空，但表单仍在提交，无论它是空白还是重复。

这是我的模特：

class Post extends AppModel {

    var $name = 'Post';
    var $validate = array(
        'title'=>array(
            'title_must_not_be_blank'=>array(
                'rule'=>'notEmpty',
                'message'=>'This post is missing a title!'
            ),
            'title_must_be_unique'=>array(
                'rule'=>'isUnique',
                'message'=>'A post with this title already exists!'
            )
        ),
        'body'=>array(
            'body_must_not_be_blank'=>array(
                'rule'=>'notEmpty',
                'message'=>'This post is missing its body!'
            )
        )
    );
}

这是控制器：

class PostsController extends AppController {

    var $name = 'Posts';

    function index() {
        $this->set('posts', $this->Post->find('all'));
    }

    function view($id = NULL) {
        $this->set('post', $this->Post->read(NULL, $id));
    }

    function add() {
        if (!empty($this->request->data)) {
            if($this->Post->save($this->request->data)) {
                $this->Session->setFlash('The post was successfully added!');
                $this->redirect(array('action'=>'index'));
            } else {
                $this->Session->setFlash('The post was not saved... Please try again!');

            }
        }
    }

    function edit($id = NULL) {
        if(empty($this->data)) {
            $this->data = $this->Post->read(NULL, $id);
        } else {
            if($this->Post->save($this->data)) {
                $this->Session->setFlash('The post has been updated');
                $this->redirect(array('action'=>'view', $id));
            }
        }
    }

    function delete($id = NULL) {
        $this->Post->delete($id);
        $this->Session->setFlash('The post has been deleted!');
        $this->redirect(array('action'=>'index'));
    }

}

以下是观点：

<h2>Add a Post</h2>
<?php
echo $this->Form->create('Post', array('action'=>'add'));
echo $this->Form->input('title');
echo $this->Form->input('body');
echo $this->Form->end('Create Post');
?>

<p><?php echo $this->Html->link('Cancel', array('action'=>'index')); ?></p>

提前致谢！

问题是您尝试使用的规则未在CakePHP框架中定义。如果你想要一些东西并确保该字段不是空的，你应该试试这个：

 'title' => array(
            'required' => array(
                'rule' => array('minLength', 1),
                'allowEmpty' => false,
                'message' => 'Please enter a title.'
            )          
       ),

'required'键告诉Cake该字段是必需的，而'allowEmpty' => false告诉Cake该字段需要包含某些内容而不能只是一个空字符串。

CakePHP表单验证不起作用
