如何显示cakehp2.5.3模型验证消息.默认情况下，它显示html 5验证消息

Question

如何显示CakePHP模型中定义的验证消息。当我提交表单时，CakePHP模型验证工作正常。但不会显示输入字段的验证消息。它显示HTML 5验证消息。我想显示CakePHP模型验证消息。我使用的是CakePHP 2.5.3

以下是我的代码块：

控制器：

$this->User->set($this->request->data);
    if ($this->User->validates()) {
        if ($this->User->save($this->request->data)) {
            $Email->send();
            $this->Session->setFlash(__('The user has been created'));
            if ($this->Auth->login()) {
                $this->Session->setFlash(__('Welcome, ' . $this->Auth->user('username')));
                $this->redirect($this->Auth->redirectUrl());
            }
        } else {
            $this->Session->setFlash(__('The user could not be created. Please, try again.'));
        }
    }

型号：

public $validate = array(
    'username' => array(
        'nonEmpty' => array(
            'rule' => array('notEmpty'),
            'message' => 'A username is required',
            'allowEmpty' => false
        ),
        'unique' => array(
            'rule' => array('isUniqueUsername'),
            'message' => 'This username is already in use'
        ),
        'alphaNumericDashUnderscore' => array(
            'rule' => array('alphaNumericDashUnderscore'),
            'message' => 'Username can only be letters, numbers and underscores'
        ),
    )

视图：

<div id="divfirstname" class="input text required">
                    <label for="UserFirstname">First Name <span style="color:#FF0000">*</span></label>
                     <?php echo $this->Form->text('firstname');?>
                </div>
                <div id="divlastname"  class="input text required">
                    <label for="UserLastname">Last Name <span style="color:#FF0000">*</span></label>
                    <?php echo $this->Form->text('lastname');?>
                </div>
                <div class="input text required">
                    <label for="UserUsername">Username <span style="color:#FF0000">*</span></label>
                    <?php echo $this->Form->text('username');?>
                </div>

Answer 1

您不需要将验证块封装在保存调用中。

所以这就足够了：

    if ($this->User->save($this->request->data)) {
        $Email->send();
        $this->Session->setFlash(__('The user has been created'));
        if ($this->Auth->login()) {
            $this->Session->setFlash(__('Welcome, ' . $this->Auth->user('username')));
            $this->redirect($this->Auth->redirectUrl());
        }
    } else {
        $this->Session->setFlash(__('The user could not be created. Please, try again.'));
    }

CakePHP在调用Model->save()时自动处理验证，并在输入字段下显示错误。因此，如果$this->save由于验证错误而失败，cakepp会在右侧输入字段下添加<div class="error-message">Message Text from your model validation array</div>。

您只剩下两个选项：

1. 要么不要在cakeHP中使用验证规则，后者在客户端进行验证。

2. 在DOM就绪时，像一样调用$("#formId").removeAttr('novalidate');

   $(document).ready(function(){ $("#formId").removeAttr('novalidate'); });
