模型上的 cakephp 数据验证问题

Question

我正在处理cakephp v2.3。虽然我是 $this->User->validates 的验证数据，但即使存在值，它也将始终返回 false。

这是我的验证规则

public $validate = array(
        'first_name' => array(
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'message' => 'This field cannot be left blank.',
                'last' => true,
                'required' => true,
            ),
            'size' => array(
                'rule' => array('maxLength', 50),
                'message' => 'This field must be no larger than 50 characters long.'
            ),
        ),
        'last_name' => array(
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'message' => 'This field cannot be left blank.',
                'last' => true,
                'required' => true,
            ),
            'size' => array(
                'rule' => array('maxLength', 50),
                'message' => 'This field must be no larger than 50 characters long.',
                'allowEmpty' => true,
            ),
        ),

        'email' => array(
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'message' => 'This field cannot be left blank.',
                'last' => true,
                 'required' => true,
            ),

            'checkMail' => array(
                'rule' => 'checkMail',
                'message' => 'Please provide a valid email address.',
                'last' => true,
            ),
            'isUnique' => array(
                'rule' => 'isUnique',
                'message' => 'Email address already in use.',
                'last' => true,
            ),
        ),
        'password' => array(
            'rule1' => array(
                'rule' => array('minLength', 6),
                'message' => 'Passwords must be at least 6 characters long.',
                 'required' => true,
            ),

        ),
        'verify_password' => array(
            'rule' => 'validIdentical',
        ),
        'current_pass' => array(
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'message' => 'This field cannot be left blank.',
                'last' => true,
            ),
            'match' => array(
                'rule' => 'validICurrent',
            )
        ),
        'gender' => array(
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'message' => 'This field cannot be left blank.',
                'last' => true,
            ),
        ),
        'mobile' => array(
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'message' => 'This field cannot be left blank.',
                'last' => true,
                 'required' => true,
            ),
            'numeric' => array(
                'rule' => 'numeric',
                'message' => 'Please enter valid phone numbers.',
            )
        ),
        'image' => array(
            'SizeLimit' => array(
                'rule' => array('isUnderPhpSizeLimit', false),
                'message' => 'File exceeds upload filesize limit',
            ),
            'FormSizeLimit' => array(
                'rule' => array('isUnderFormSizeLimit', false),
                'allowEmpty' => true,
                'message' => 'File exceeds form upload filesize limit'
            ),
            'CompletedUpload' => array(
                'rule' => array('isCompletedUpload', false),
                'message' => 'File was not successfully uploaded'
            ),
            'ValidExtension' => array(
                'allowEmpty' => true,
                'rule' => array('isValidExtension', array('gif', 'png', 'jpg', 'jpeg'), false),
                'message' => 'File does not have a gif, png, ,jpg and  jpeg extension'
            )
        ),
    );

这就是我验证的方式

    if ($this->request->is("post")) {
        if (!empty($this->request->data)) {

            if (!$this->User->validates($this->request->data)) {
                $this->Session->setFlash(__('The Information could not be saved. Please, try again.'), 'message', array('class' => 'danger'));
                $this->redirect(Router::url('/', true) . 'sign-up/');
            }
        }

当我尝试时

die(debug($this->User->invalidFields()));

它会返回

array(
    'password' => '*****',
    'last_name' => array(
        (int) 0 => 'This field cannot be left blank.',
        (int) 1 => 'This field cannot be left blank.'
    ),
    'email' => array(
        (int) 0 => 'This field cannot be left blank.',
        (int) 1 => 'This field cannot be left blank.'
    ),
    'mobile' => array(
        (int) 0 => 'This field cannot be left blank.',
        (int) 1 => 'This field cannot be left blank.'
    )
)

这是我传递的数据

Array
(
    [User] => Array
        (
            [role_id] => 2
            [first_name] => kapil
            [last_name] => sharma
            [email] => kapiltest@mailinator.com
            [password] => abc@123
            [verify_password] => abc@123
            [mobile] => 1234567890
            [gender] => Male
            [image] => Array
                (
                    [name] => Screenshot_61.png
                    [type] => image/png
                    [tmp_name] => /tmp/phppYBJQF
                    [error] => 0
                    [size] => 50611
                )
        )
)

Answer 1

你的验证对我来说似乎很好但是如果我们不在模型中设置数据一段时间就会导致这种问题。

在验证之前添加以下行。

$this->User->set($this->request->data);

所以代码应该是这样的

$this->User->set($this->request->data); //set data in model

if (!$this->User->validates()) {
    $this->Session->setFlash(__('The Information could not be saved. Please, try again.'), 'message', array('class' => 'danger'));
    $this->redirect(Router::url('/', true) . 'sign-up/');
}
