圖片上傳在cakephp中並沒有上傳到文件夾

Question

我想上傳圖片，但它正在保存在數據庫中，但有一個問題將文件保存在webroot文件夾中。是否有任何可能的錯誤，那麼請給我提供建議 我的控制器是這樣的：

if ($this->request->is('post')) { 
      //echo '<pre>';print_r($this->request->data);exit; 
      $this->request->data['MediaManagement']['created_date']= date('Y-m-d H:i:s'); 
      $this->request->data['MediaManagement']['status'] = 'unpublish';//default 
      $this->request->data['MediaManagement']['user_id'] = $this->Auth->user('id'); 
      $random_number = $this->Smart->random_code(); 

      //echo $random_number;exit; 
      $tmp_name = $this->request->data['MediaManagement']['file_name']['tmp_name']; 
      $name = $this->request->data['MediaManagement']['file_name']['name']; 
      if(empty($this->request->data['MediaManagement']['media_category_id'])){ 
       $this->request->data['MediaManagement']['media_category_id'] = 0; 
      } 
      $this->request->data['MediaManagement']['file_type'] = $this->Smart->get_file_extention($this->request->data['MediaManagement']['file_name']['name']); 

      if(file_exists(WWW_ROOT.'mediafiles/'.$name)) 
      { 
       $name= $random_number.$this->request->data['MediaManagement']['file_name']['name']; 
      } 




      $this->request->data['MediaManagement']['file_name'] = $name; 
      //debug($this->request->data);exit; 
      $this->MediaManagement->create(); 
      if ($this->MediaManagement->save($this->request->data)) { 
       move_uploaded_file($tmp_name, WWW_ROOT.'mediafiles/'.$name); 

       $last_mediamanagement_id = $this->MediaManagement->getLastInsertID(); 
       $this->Session->setFlash(__('The media has been saved')); 
       $this->redirect(array('action' => 'redirectview/'.$last_mediamanagement_id)); 
      } else { 
       $this->Session->setFlash(__('The media management could not be saved. Please, try again.')); 
      } 
     } 
     $mediaCategories = $this->MediaManagement->MediaCategory->find('list'); 
     $users = $this->MediaManagement->User->find('list'); 
     $this->set('currentUserId',$this->Auth->user('id')); 
     $this->set(compact('mediaCategories', 'users')); 

    }

您清除與$this->request->data['MediaManagement']['file_name'] = $name;

文件信息數組這應該是：$this->request->data['MediaManagement']['file_name']['name'] = $name;

更新（改代碼一點）：

//in view: 
echo $this->Form->input('MediaManagement.file', array(/*your options*/));//instead of MediaManagement.file_name 

//in controller: 
if($this->request->is('post')) { 
    //echo '<pre>';print_r($this->request->data);exit; 
    $this->request->data['MediaManagement']['created_date']= date('Y-m-d H:i:s'); 
    $this->request->data['MediaManagement']['status'] = 'unpublish';//default 
    $this->request->data['MediaManagement']['user_id'] = $this->Auth->user('id'); 

    $path = WWW_ROOT.'mediafiles'.DS; 
    if(!is_dir($path)) { 
     mkdir($path, 0777); 
    } 

    $tmp_name = $this->request->data['MediaManagement']['file']['tmp_name']; 
    $name = $this->request->data['MediaManagement']['file']['name']; 
    if(empty($this->request->data['MediaManagement']['media_category_id'])){ 
     $this->request->data['MediaManagement']['media_category_id'] = 0; 
    } 

    //you should get the file_type based on the mime type and not based on the extention, because the extension can be manipulated by the user 
    $this->request->data['MediaManagement']['file_type'] = $this->Smart->get_file_extention($this->request->data['MediaManagement']['file']['name']); 

    while(file_exists($path.$name)) { 
     $name = $this->Smart->random_code().$this->request->data['MediaManagement']['file']['name']; 
    } 
    $this->request->data['MediaManagement']['file_name'] = $name; 

    $this->MediaManagement->create(); 
    if ($this->MediaManagement->save($this->request->data)) { 
     $last_mediamanagement_id = $this->MediaManagement->getLastInsertID(); 

     if(move_uploaded_file($tmp_name, $path.$name)) { 
      $this->Session->setFlash(__('The media has been saved')); 
      $this->redirect(array('action' => 'redirectview/'.$last_mediamanagement_id)); 
     } else { 
      $this->Session->setFlash(__('Could not upload file. Please, try again.')); 
      $this->MediaManagement->delete($last_mediamanagement_id);//delete from database 
     } 
    } else { 
     $this->Session->setFlash(__('The media management could not be saved. Please, try again.')); 
    } 
} 
$mediaCategories = $this->MediaManagement->MediaCategory->find('list'); 
$users = $this->MediaManagement->User->find('list'); 
$this->set('currentUserId',$this->Auth->user('id')); 
$this->set(compact('mediaCategories', 'users'));
