Codeigniter - 如何上傳帶縮略圖的原始圖像？

Question

我有這樣的代碼在笨文件上載：

if(!empty($_FILES['userfile'])){ 
    $name_array = array(); 
    $count = count($_FILES['userfile']['size']); 
    foreach($_FILES as $key => $value) 
     for ($s=0; $s<=$count-1; $s++){ 
      $_FILES['userfile']['name'] = $value['name'][$s]; 
      $_FILES['userfile']['type'] = $value['type'][$s]; 
      $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s]; 
      $_FILES['userfile']['error'] = $value['error'][$s]; 
      $_FILES['userfile']['size'] = $value['size'][$s]; 
      $config['upload_path'] = './public/images/campaign-images/'; 
      $config['allowed_types'] = 'gif|jpg|jpeg|png|GIF|JPG|JPEG|PNG'; 
      $config['max_size'] = '10000'; 
      //$config['max_width'] = '1024'; 
      //$config['max_height'] = '768'; 
      $CI->load->library('upload', $config); 
      $CI->upload->do_upload(); 
      $data = $CI->upload->data(); 
      $name_array[] = $data['file_name']; 
     } 
    return $name_array; 
} 

此代碼工作完美單原圖上傳，但如何上傳圖片縮略圖像（350×250），具有不同的文件夾中調整大小。

任何想法如何處理codeigniter庫？

感謝

首先存儲原始圖像和之後的縮略圖將上傳 你只需要包括GD2庫生成縮略圖

  if(!empty($_FILES['userfile'])){ 
       $name_array = array(); 
       $count = count($_FILES['userfile']['size']); 
       foreach($_FILES as $key => $value) 
        for ($s=0; $s<=$count-1; $s++) 
        { 
         //Original Image Upload - Start 
         $_FILES['userfile']['name'] = $value['name'][$s]; 
         $_FILES['userfile']['type'] = $value['type'][$s]; 
         $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s]; 
         $_FILES['userfile']['error'] = $value['error'][$s]; 
         $_FILES['userfile']['size'] = $value['size'][$s]; 
         $config['upload_path'] = './public/images/campaign-images/'; 
         $config['allowed_types'] = 'gif|jpg|jpeg|png|GIF|JPG|JPEG|PNG'; 
         $config['max_size'] = '10000'; 
         //$config['max_width'] = '1024'; 
         //$config['max_height'] = '768'; 
         $CI->load->library('upload', $config); 
         $CI->upload->do_upload(); 
         $data = $CI->upload->data(); 
         //Original Image Upload - End 

         //Thumbnail Image Upload - Start 
         $config['image_library'] = 'gd2'; 
         $config['source_image'] = './public/images/campaign-images/'. $value['name'][$s]; 
         $config['new_image'] = './public/images/campaign-images/thumbs/'.$value['name'][$s]; 
         $config['width'] = 350; 
         $config['height'] = 250; 

         //load resize library 
         $this->load->library('image_lib', $config); 
         $this->image_lib->resize(); 
         //Thumbnail Image Upload - End 

         $name_array[] = $data['file_name']; 
        } 
       return $name_array; 
      }

if(!empty($_FILES['userfile'])){ 
      $name_array = array(); 
      $count = count($_FILES['userfile']['size']); 
      foreach($_FILES as $key => $value) 
       for ($s=0; $s<=$count-1; $s++) 
       { 
        //Original Image Upload - Start 
        $_FILES['userfile']['name'] = $value['name'][$s]; 
        $_FILES['userfile']['type'] = $value['type'][$s]; 
        $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s]; 
        $_FILES['userfile']['error'] = $value['error'][$s]; 
        $_FILES['userfile']['size'] = $value['size'][$s]; 
        $config['upload_path'] = 'PATH_TO_UPLOAD_IMAGE'; 
        $config['allowed_types'] = 'gif|jpg|jpeg|png|GIF|JPG|JPEG|PNG'; 
        $config['max_size'] = '10000'; 
        $CI->load->library('upload', $config); 
        $CI->upload->do_upload(); 
        $data = $CI->upload->data(); 
        //Original Size of Image Upload - End 

        //Thumbnail Size of Image Upload - Start 
        $config['image_library'] = 'gd2'; 
        $config['source_image'] = 'PATH_TO_IMAGE_UPLOAD'. $value['name'][$s]; 
        $config['new_image'] = 'PATH_TO_UPLOAD_THUMB_IMAGE'.$value['name'][$s]; 
        $config['width'] = 350; 
        $config['height'] = 250; 

        //CI load resize library 
        $this->load->library('image_lib', $config); 
        $this->image_lib->resize(); 
        //Thumbnail SIZED Image Upload - End 

        $name_array[] = $data['file_name']; 
       } 
      return $name_array; 
     }
