Question

有没有办法验证数据（使用CakePHP的模型验证），以确保至少“a”或“b”有数据（两者都不必有数据）。

Answer 1

在你的模型中，做这样的事情。执行保存操作时将调用该函数。

public $validate = array(
    'a' => array(
        'customCheck' => array(
            'rule' => 'abCheck',
            'message' => 'You must enter data in a or b.'
        )
    ),
    'b' => array(
        'customCheck' => array(
            'rule' => 'abCheck',
            'message' => 'You must enter data in a or b.'
        )
    )
);

//Function must be public for Validator to work
//Checks to see if either a or b properties are set and not empty
public function abCheck(){
    if((isset($this->data['Model']['a']) && !empty($this->data['Model']['a'])) || (isset($this->data['Model']['b']) && !empty($this->data['Model']['b']))){
         return true;
    }
    return false;
}

Answer 2

您可以通过“自定义验证”验证这些条件。

Answer 3

请改为尝试：

public $validate = array(
     'a' => array(
         'customCheck' => array(
             'rule' => array('abCheck', 1),
             'message' => 'You must enter data in a or b.'
         )
     ),
     'b' => array(
         'customCheck' => array(
             'rule' => array('abCheck', 1),
             'message' => 'You must enter data in a or b.'
         )
     )
 );

 //Function must be public for Validator to work
 //Checks to see if either a or b properties are set and not empty
 public function abCheck(){
     if((isset($this->data['Model']['a']) && !empty($this->data['Model']['a'])) > || (isset($this->data['Model']['b']) && !empty($this->data['Model']['b']))){
          return 1;
     }
     return -1;
 }

CakePHP中的模型验证检查至少设置了一个或另一个
