Validation messages are not showing in cakephp 2.4.x

本文关键字：显示验证消息 cakephp | 更新日期: 2023-09-27

下面是我在User.php中的验证规则

public $validate = array(
    'username' => array(
        'required' => array(
            'rule' => array('notEmpty'),
            'message' => 'User name is required'
        ),
        'alphaNumeric'=>array(
            'rule' => 'alphaNumeric',
            'required' => true,
            'message' => 'Alphabets and numbers only'
        )
    ))

这是我的视图页面代码

<?php
      echo $this->Form->create('User');
      echo $this->Form->input('username', array('label' => 'Username'));
      echo $this->Form->input('email', array('label' => 'Email'));
      echo $this->Form->input('password', array('label' => 'Password'));
      echo $this->Form->submit('Sign Up');
      echo $this->Form->end();
?>

这是我的控制器代码

public function register() {
$this->layout = 'starter';
//debug($this->validationErrors);
if ($this->request->is('post')) {
    if ($this->User->validates()) {
        $this->User->save($this->request->data);
        $this->Session->setFlash(__('Please login your account'));
        $this->redirect('/users/login');
      } else {
        $this->Session->setFlash(__('The user could not be saved. Please, try again.'));
      }
 }
}

但是没有显示验证消息。

你的代码是错误的。

if ($this->request->is('post')) {
    if ($this->User->validates()) {
        $this->User->save($this->request->data);

这是不可能的，因为数据在验证之前没有传递。

您需要首先传递数据，然后验证，然后可选地保存(或保存和验证一起):

if ($this->request->is('post')) {
    if ($this->User->save($this->request->data)) {}

或，注意不要再次触发验证:

if ($this->request->is('post')) {
    $this->User->set($this->request->data);
    if ($this->User->validates()) {
        $success = $this->User->save(null, array('validate' => false));

但这是有记录的。

后一种方法只有在需要分两步完成时才有意义。

在你的评论中你写了你已经改变了布局页面。你可能会错过

<?php echo $this->Session->flash(); ?>

这条线。在view/layouts/yourlayout中添加这一行。ctp文件。

在视图页面代码中禁用HTML5 required

<?php
  echo $this->Form->create('User');
  echo $this->Form->input('username', array('label' => 'Username','required'=>'false'));
  echo $this->Form->input('email', array('label' => 'Email','required'=>'false'));
  echo $this->Form->input('password', array('label' => 'Password','required'=>'false'));
  echo $this->Form->submit('Sign Up');
  echo $this->Form->end();
?>
