cakephp中扩展自定义验证规则
在CAKEPHP中,有多达26条验证规则可以用,详细的见这里:
http://book.cakephp.org/view/1181/Adding-your-own-Validation-Methods#!/view/1152/Core-Validation-Rules
但如何扩展自定义呢?比如一个例子中,只对管理员用户要校验输入用户名,普通用户不用
(一个很极端的例子),可以这样做:
class User extends AppModel {
var $name = 'User';
var $validate = array(
'name' => array('notempty' =>
array('rule' => array('notempty'),
'message' => 'Please enter first name',
......
.......
'username' => array('custom' =>
array('rule' => array('validateDependentFields'),
'message' => 'Please enter height',
这里对username使用自定义的方法,定义一个方法validateDependentFields去校验
方法为:
function validateDependentFields($field){ $passed=true; switch(true){ case array_key_exists('username',$field): if( $this->data['User']['user_type_id']==1 and (!isset($this->data['User']['username']) or empty($this->data['User']['username'])) ){ $passed=false; }else{ $passed=true; } break; case array_key_exists('class_of',$field): if( $this->data['User']['user_type_id']==1 and (!isset($this->data['User']['class_of']) or empty($this->data['User']['class_of'])) ){ $passed=false; }else{ $passed=true; } break; } return $passed; }
