如何在cakePHP 2.0的數據庫字段中保存特定值？

Question

我試圖將CakePHP從1.3遷移到2.0。而現在，我遇到了一個小問題，就是將值插入特定的字段。下面是我在1.3版本中所做的代碼：

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')); 

} 

現在，這裏是我的代碼中，我想包括用戶ID（表示爲UID），後日（代表作爲DatePosted）和用戶的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')); 

} 

現在，我的問題是如何保存我之前提到過的那三個字段？

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 

應該這樣做。

CakeRequest::data provides dot notation access to request data. Allows for reading and modification of request data, calls can be chained together as well

以供將來參考，如果你有一個叫datetimecreated與null默認值字段，蛋糕會自動神奇地插入記錄創建時間 - 也許消除DatePosted的需要。
