我无法捕获验证错误并将其显示到CakePHP控制器类中。 我有这个模型:

public $validate = array(
    'username' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
            'message' => 'Your custom message here',
            'allowEmpty' => false,
            'required' => true,
            //'last' => false, // Stop validation after this rule
            //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'alphaNumeric' => array(
            'rule' => array('alphaNumeric'),
            'message' => 'Your custom message here',
            //'allowEmpty' => false,
            //'required' => false,
            //'last' => false, // Stop validation after this rule
            //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'maxLength' => array(
            'rule' => array('maxLength', 50),
            'message' => 'Your custom message here',
            //'allowEmpty' => false,
            //'required' => false,
            //'last' => false, // Stop validation after this rule
            //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),

    ));
这就是我在将新元素保存到数组中时,如何将验证消息捕获到控制器中的方法:

public function add() {

    if ($this->request->is('post')) {
        $this->Admin->set($this->request->data);
        //$this->Admin->create();
        if ($this->Admin->validates()) {
            // it validated logic
            if ($this->Admin->save($this->request->data)) {
                $this->Session->setFlash(__('The admin has been saved.'));
                return $this->redirect(array('action' => 'index'));
            } else {
                $this->Session->setFlash(__('The admin could not be saved. Please, try again.'));
            }
        } else {
            // didn't validate logic
            $errors = $this->Admin->validationErrors;
            debug($errors);
        }
    }
}
但它不起作用。如果我传递了一个空字段,则带有默认消息的警报将显示在add.ctp页面中。如果插入副本,则不会显示任何消息。

您不需要

$this->Admin->set($this->request->data);
$this->Admin->validates(){}
因为如果你用的是“保存”

正在验证。这应该可以完成任务。

我添加了$this->Admin->set($this->request->data);我的回答是。如果使用“保存”,则不需要->设置()和->验证()。
$this->Admin->save($this->request->data)
