如何从CakePHP中的单个位置验证多个字段？

Question

我想在一个地方验证多个字段。因此，我在一个表格中包含了4个字段 如下

1. facebook_link
2. twitter_link
3. GOOGLE_PLUS_LINK
4. linked_in_link

用户至少键入上述任何一个字段。请帮助我获得解决方案，用户键入表单中的任何链接。

Answer 1

您可以添加自己的验证方法。

public $validate = array(
    'facebook_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
    'twitter_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
    'google_plus_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
    'linked_in_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
);

public function validateLink($link) {
    $allFieldsAreEmpty = (
        empty($this->data[$this->alias]['facebook_link']) &&
        empty($this->data[$this->alias]['twitter_link']) &&
        empty($this->data[$this->alias]['google_plus_link']) &&
        empty($this->data[$this->alias]['linked_in_link'])
    );

    return !$allFieldsAreEmpty;
}

希望这对你有用。

var windowObjectReference = null; // global variable

function showAsReservation(url){    
   if(windowObjectReference == null || windowObjectReference.closed){
        windowObjectReference = window.open(url,
            "_blank","toolbar=no,scrollbars=no, resizable=yes,top=500, left=500, width=400, height=400");
      }
      else
      {
        windowObjectReference.focus();
      };
    windowObjectReference.focus();
}
