我的验证代码是这样的:
public $validate = array(
'name' => array(
'rule' =>array(
'rule'=>'notEmpty',
'required' => true ,
'allowEmpty' => false ,
'on'=>'create',
'message' => 'This field cannot be left empty'
)
),
'email' => array(
'rule1' => array(
'rule' => 'isUnique',
'required' => true,
'allowEmpty' => false,
'on'=>'create',
'message' => 'This email has already been taken.'
),
'rule2' => array(
'rule' => array('email'),
'required' => true,
'on'=>'create',
'message' => 'Please supply a valid email address.'
),
),
'password' => array(
'Not Empty' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Password must not be empty.'
),
'password_contains' => array(
'rule'=>'alphaNumeric',
'message' => 'Password must contain letters and numbers'
),
'password_length' => array(
'rule' => array('lengthBetween', 5, 15),
'required' => true,
'message' => 'Passwords must be between 5 and 15 characters long.'
),
'passwords match' => array(
'rule' => 'matchPasswords',
'message' => 'Your passwords do not match'
)
),
'password_again' => array(
'Not Empty' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Password must not be empty.'
),
)
);
public function matchPasswords($data)
{
if ($data['password'] == $this->data['User']['password_again']) {
return true;
} else {
$this->invalidate('password_again', 'Your passwords do not match');
return false;
}
}
但是每次我运行代码，我得到这些错误:
通知(8):未定义偏移量:0 [CORE'Cake'Model'Validator'CakeValidationRule.php，行342]警告(512):无法找到名称的验证处理程序[CORE'Cake'Model'Validator'CakeValidationRule.php, line 281]
我不明白是什么问题。任何帮助都将不胜感激。谢谢! !
问题在这里
'name' => array(
'rule' => array(
'rule'=> 'notEmpty',
//...
)
)
把第一个rule键改成别的
'name' => array(
'validName' => array(
'rule' => array('notEmpty'),
//...
)
)
这些错误的原因如下。当找到rule键时，Cake尝试从其值解析验证处理程序的名称。在第二个例子中，它试图从array('notEmpty')中获取索引0处的值，该值被解析为notEmpty方法，一切正常。回到原来的name规则，Cake试图从array('rule'=>'notEmpty',...)获得索引0的值，没有这样的索引(偏移量)，无法找到验证处理程序并触发错误。
