Question

我正在尝试将CakePHP从1.3迁移到2.0。现在，我遇到了一个关于将值插入特定字段的小问题。这是我在1.3版中创建的代码：

function add() {

    if(isset($_SESSION['User']['id'])){ 
        if(!empty($this->data)) {
            if($this->Ad->save($this->data)){

                //saving the uID in table ads
                $this->data['Ad']['uID'] = $_SESSION['User']['id'];  
                $this->data['Ad']['DatePosted'] = DboSource::expression('NOW()');     
                $this->data['Ad']['IP'] = $_SERVER['REMOTE_ADDR'];   
                $this->Ad->save($this->data, FALSE);                    

                $this->Session->setFlash('The post was successfully added!');
                $this->redirect(array('action'=>'index'));
            }
            else{
            $this->Session->setFlash('The post was not saved. Please try again.', 'alert-message', array('class'=>'error'));
            }               
        }
    }
    else{
        $this->Session->setFlash('You have to login first to access control panel');
        $this->redirect(array('controller'=>'users','action'=>'login'));
    }   


    //for setting the category of advertisement
    $adcats = $this->Ad->Adcat->find('list',array('fields'=>array('id','Description')));
    $this->set(compact('adcats'));

    //for setting the type of advertisement
    $adtyps = $this->Ad->Adtyp->find('list',array('fields'=>array('id','Description')));
    $this->set(compact('adtyps'));  

}

现在，我的代码中包含用户ID（表示为uID），发布日期（表示为DatePosted）以及用户的IP地址。

public function add() {

    if($this->Session->read('user_id')){    
        if($this->request->is('post')) {
            if($this->Ad->save($this->request->data)){

                //saving the uID in table ads
                //$this->data['Ad']['uID'] = $this->Session->read('user_id');  
                //$this->data['Ad']['DatePosted'] = DboSource::expression('NOW()');     
                //$this->data['Ad']['IP'] = $_SERVER['REMOTE_ADDR'];   

                $this->Ad->uID = $this->Session->read('user_id'); 
                $this->Ad->DatePosted = DboSource::expression('NOW()');
                $this->Ad->IP = $_SERVER['REMOTE_ADDR']; 

                $this->Ad->save($this->request->data);                  

                $this->Session->setFlash('The post was successfully added!');
                $this->redirect(array('action'=>'index'));
            }
            else{
            $this->Session->setFlash('The post was not saved. Please try again.', 'alert-message', array('class'=>'error'));
            }               
        }
    }
    else{
        $this->Session->setFlash('You have to login first to access control panel');
        $this->redirect(array('controller'=>'users','action'=>'login'));
    }   

    //for setting the category of advertisement
    $adcats = $this->Ad->Adcat->find('list',array('fields'=>array('id','Description')));
    $this->set(compact('adcats'));

    //for setting the type of advertisement
    $adtyps = $this->Ad->Adtyp->find('list',array('fields'=>array('id','Description')));
    $this->set(compact('adtyps'));  

}

现在，我的问题是如何保存我之前提到的那三个字段？

Answer 1

if($this->Session->read('user_id')){    
    if($this->request->is('post')) {

        $this->request->data('Ad.uID', $this->Session->read('user_id'));
        $this->request->data('Ad.DatePosted', DboSource::expression('NOW()'));
        $this->request->data('Ad.IP', $this->request->clientIp());
        // or $_SERVER['REMOTE_ADDR'];

        if($this->Ad->save($this->request->data)){

            $this->Session->setFlash('The post was successfully added!');
            $this->redirect(array('action'=>'index'));
        }
        // and so on

应该这样做。

CakeRequest :: data提供对请求数据的点表示访问。允许对于读取和修改请求数据，可以链接呼叫在一起

为了将来参考，如果你有一个名为created datetime的字段，其默认值为null，那么Cake会自动神奇地插入记录创建时间 - 也许消除了需要DatePosted。

如何在cakePHP 2.0中的DB字段中保存特定值？
