我在进行自定义验证,但在无效时不显示错误消息。你知道问题出在哪里吗?我认为问题可能出在无效函数中。你知道如何为像这样的嵌套验证设置它吗?
var $validate = array(
'receiver' => array(
'maxMsg' => array(
'rule' => array('maxMsgSend'),
//'message' => ''
),
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'field must not be left empty'
))......
模型中的自定义验证方法:
function maxMsgSend ( $data )
{
$id = User::$auth['User']['id'];
$count_contacts = (int)$this->Contact->find( 'count', array( 'conditions' =>array( 'and' =>array( 'Contact.contact_status_id' => '2',
'Contact.user_id' => $id))));
$current_credit = (int)$this->field( '3_credit_counter', array( 'id' => $id));
$max_allowed_messages = ($count_contacts >= $current_credit)? $current_credit: $count_contacts ;
if ($data>$max_allowed_messages)
{
$this->invalidate('maxMsg', "you can send maximum of {$max_allowed_messages} text messages.");
}
}
更新:如何解决它。我将函数的内容移到模型中的 beforeValidate() 中。
function beforeValidate($data) {
if (isset($this->data['User']['receiver']))
{
$id = User::$auth['User']['id'];
$count_contacts = (int)$this->Contact->find( 'count', array( 'conditions' =>array( 'and' =>array( 'Contact.contact_status_id' => '2',
'Contact.user_id' => $id))));
$current_credit = (int)$this->field( '3_credit_counter', array( 'id' => $id));
$max_allowed_messages = ($count_contacts >= $current_credit)? $current_credit: $count_contacts ;
if ($data>$max_allowed_messages)
{
$this->invalidate('receiver', "you can send maximum of {$max_allowed_messages} text messages.");
return false;
}
}
return true;
}
