validation之CakePHP之使用相同规则验证多个字段

假设我有十几个单选按钮字段，我想根据两个通用规则对其进行验证。

   'valid'=> array( 
        'rule' => array('inList', array('yes','no')), 
        'message' => 'Illegal Choice Detected' 
 
   ), 
   'required'=> array( 
       'rule' => array('notEmpty'), 
       'message' => 'Field is required.' 
   ), 

如何在不必将每个验证规则分配给每个字段的情况下执行此操作？

对于那些像我自己有时喜欢用勺子喂食的人，这是我根据 Burzum 的回答做的!

   public function beforeValidate($options = []) { 
        $fields = ['field_1','field_2','field_3','etc']; 
        foreach ($fields as $field) {             
            $this->validate[$field]['required'] = array( 
                    'rule' => array('notEmpty'), 
                    'message' => 'Field is required.' 
            ); 
            $this->validate[$field]['legal'] = array( 
                    'rule' => array('inList', array('yes', 'no')), 
                    'message' => 'An illegal choice has been detected, please contact the website administrator.' 
            ); 
        } 
        return true; 
    } 

请您参考如下方法:

将它们添加到 beforeValidate() 的 foreach 循环中

public function beforeValidate($options = []) { 
    $fields = ['field1', '...']; 
    foreach ($fields as $field) { 
        // Add your rule(s) here to the field 
        $this->validate[$field]['myRule'] = ['...']; 
    } 
    return true; 
}
