Question

我们如何在cakephp中扩展一个模型数据以检查条件到另一个控制器？

例如：

   class UsersController extends AppController
{
public function beforeFilter()
{
    $this->loadModel('Apages');
    $usr=$this->Apages->find('all');
    $this->loadModel('Pagepermissions');
    $pre=$this->Pagepermissions->find('all',array('conditions'=>array('user_id'=>'1')));

if($pre->request->data['Pagepermissions']['_add']==1)
    {
        $this->redirect(array('controller'=>'users','action'=>'add'));
    }
    else
    {
        throw new NotFoundException(__("Don't have access this Page"));
    }
}

}

在此代码中

$pre->request->data['Pagepermissions']['_add']显示错误。 请建议我怎么做

先谢谢

$ pre是数组，执行类似

的操作

$pre=$this->Pagepermissions->find('all',array('conditions'=>array('user_id'=>'1')));
 if(!empty($pre)){
    foreach($pre as $v){
        if($v['Pagepermissions']['_add']==1){
            $this->redirect(array('controller'=>'users','action'=>'add'));
            return;
        }else{
           throw new NotFoundException(__("Don't have access this Page"));
        }
    }
}else{
   throw new NotFoundException(__("user not find"));
}
