在Codeigniter中使用不同的输入文件上传多个图像

Question

因此，我的表单中有四个输入文件，并使用以下索引将其发送到全局$ _FILES上：前，后，右和左。

我想上传这些使用codeigniter图像类库。这是我的代码：

public function upload_to_temp($id, $folder, $tags){ 
      $path = realpath(APPPATH . '../public/resources/temps/' . $folder); 
      //makes a directory 
      mkdir($path . '/' . $id, 0700); 
      //navigate to the newly created path 
      $path = realpath(APPPATH . '../public/resources/temps/' . $folder . '/' . $id); 

      if(isset($tags)){ 
       //use these tags to check the files present on submission 
       foreach($tags as $tag){ 
        if(array_key_exists($tag,$_FILES)){ 
         if(!empty($_FILES) && $_FILES[$tag]["name"] != "" && isset($_FILES[$tag]["name"])){ 
          $config = array (
           'source_image' => $_FILES[$tag]["name"], 
           'image_library' => 'gd', 
           'upload_path' => $path, 
           'file_name' => $id . '_' . $tag . '.jpg', 
           'allowed_types' => 'png|jpg|jpeg', 
           'overwrite' => TRUE, 
           'max_size' => '2000', 
          ); 
          $this->_CI->upload->initialize($config); 
          if(!$this->_CI->upload->do_upload()){ 
           echo 'Error creating image. '; 
           echo $this->_CI->upload->display_errors(); 
          }else{ 
           echo 'Success saving to temp folder'; 
          } 

          //kapag failed 
          if(!$this->_CI->upload->do_upload()){ 
           echo 'Error creating image.'; 
           echo $this->_CI->upload->display_errors(); 
          }else{ 
           //now, the $path will become our resource path for copying and creating thumbnails. 
           $resouce_path = $config['upload_path'] . '/' . $config['file_name']; 
           $this->img_create_thumb($resouce_path, $folder); 
          } 

         }else{ 
          //Hindi na dapat marating to! 
          echo $tag . ' not present '; 
         } 
        }else{ 
         //use default pictures 
         echo $tag . ' not present '; 
        } 

       } 
      } 

     } 

但是它给了我下面的错误：

Error creating image.

You did not select a file to upload.

Error creating image.

You did not select a file to upload.

You did not select a file to upload.

Error creating image.

You did not select a file to upload.

Error creating image.

You did not select a file to upload.

You did not select a file to upload.

right not present left not present

我觉得我没有正确指定哪些资源上的$ _FILES应该被上传。

您的回应将不胜感激。

感谢

我解决它在CodeIgniter的do_upload（）提供的索引

$this->_CI->upload->do_upload($tag);
