php - CakePHP 为什么会出现此错误？

Question

这是错误信息:

Warning (2): preg_match() [http://php.net/function.preg-match]: Delimiter must not be alphanumeric or backslash [CORE/cake/libs/model/model.php, line 2611]

当我从 Controller 调用以下代码时会发生这种情况:

$this->Account->save($this->data)

模型看起来像这样:

class Account extends AppModel 
{       
    var $validate = array(        
        'first_name' => array(
            'rule' => array('minLength', 1),
            'required' => true   
        ),
        'last_name' => array(
            'rule' => array('minLength', 1),
            'required' => true   
        ),
        'password' => array(
            'rule' => array('minLength', 8),
            'required' => true    
        ),        
        'email' => array(
            'emailRule1' => array(
                'rule' => 'email',
                'required' => true,
                'message' => 'You must specify a valid email address' 
            ),
            'emailRule2' => array(
                'rule' => 'unique',
                'message' => 'That email address is already in our system'     
            )
        )   
    );
}

我发现了类似的问题explained here

他通过将 required' => true 更改为 required' => array(true) 解决了这个问题问题。

Answer 1

问题是我将规则命名为unique，它应该是isUn​​ique。

如果有更好的错误消息，我会更快地解决这个问题。
