【问题描述】：

以下函数通过将横幅表中的状态字段设置为 0 来检查横幅是否足够老以使其处于非活动状态。

/** * * 检查天气横幅是否足够老，可以转回非高级 * 并将状态更改为 0 ，以防非高级 * * @return 无效 */

   protected function check_status()
     $non_premium_expire = 5*24*60*60;
     $premium_expire = 14*24*60*60;
     $data = $this->Banner->find('all');
     foreach ($data as $Banners) 
            if ($Banners['Banner']['is_premium'] == 0) 
                if ((time() - strtotime($Banners['Banner']['created'])) > $premium_expire) 
                     $this->Banner->id = $Banners['Banner']['id'];
                     $this->Banner->saveField('status',0);
                
            else if ($Banners['Banner']['is_premium'] == 1) 
                if ((time() - strtotime($Banners['Banner']['created'])) > $non_) 
                    $this->Banner->id = $Banners['Banner']['id'];
                    $this->Banner->saveField('status',0);
                
            
     
   

来自 mybanners() 函数。即用户打开时应调用 check_status() 函数 /站点名称/我的横幅

我已经从下面显示的 mybanners() 函数中调用了 check_status() 函数

public function mybanners()
    


        $this->check_status();
        $this->layout = 'index';
        $this->loadModel('Banner'); 
        $loggedUserId   = $this->Auth->user('id');

我的问题是，即使尝试了 set() 和 updateAll() 函数，数据库中的一个字段状态也没有得到更新。有什么解决办法吗？我是 cakephp 的新手

【参考方案1】：

我想通了。工作代码如下。

** 
*
* Checks weather the banners are old enough to be turned back to non-premium
* and change the status to 0 , in case of non-premium
* 
* @return void 
*/

   protected function check_status()
     $non_premium_expire = 5*24*60*60;
     $premium_expire = 14*24*60*60;
     $data = $this->Banner->find('all');
     //pr ($Banners);
     //pr ((time() - strtotime($Banners['Banner']['modified'])) > 5*24*60*60);
     //pr ((time() - strtotime($Banners['Banner']['modified'])) > 14*24*60*60);
     //die();
     foreach ($data as $Banners) 
            if ($Banners['Banner']['is_premium'] == 0) 
                if ((time() - strtotime($Banners['Banner']['modified'])) > $non_premium_expire) 
                     $id = $Banners['Banner']['id'];
                     //pr ("in non premium loop");
                     //pr ($id);
                     //die();
                     $data_one = array('id' => $id , 'status'=> 0, 'modified' => false);
                     $this->Banner->save($data_one);
                     //$this->Banner->clear();
                
            
            if ($Banners['Banner']['is_premium'] == 1) 
                if ((time() - strtotime($Banners['Banner']['modified'])) > $premium_expire) 
                     $id = $Banners['Banner']['id'];
                     //pr ("in premium loop");
                     //pr ($id);
                     //die();
                     $data_one = array('id' =>$id , 'status'=> 0, 'modified' => false);
                    //pr ($data_one);
                    //die();
                     $this->Banner->save($data_one);
                     //$this->Banner->clear();
