在Codeigniter中上傳具有多個文件字段的圖像時發生沖突

Question

Codeigniter：僅設置一個字段（單個）時文件成功上傳。 但是同時設置兩個字段時，第二個文件也將上傳到第一個文件的位置。 如何解決這個沖突。 是否有關於多個上傳字段的教​​程？？？？

我的代碼如下：

<input type="file" name="filePrdimage" id="filePrdimage" size="20"/>
<input type="file" name="filePrdlogo" id="filePrdlogo" size="20"/>

。 //圖片上傳代碼

          $config['upload_path'] = 'assets/images/b2bproduct';
            $config['allowed_types'] = 'gif|jpg|jpeg|png';
            $config['max_size'] = '1000';
            $config['max_width'] = '2024';
            $config['max_height'] = '1768';
            $config['overwrite'] = TRUE;
            $config['remove_spaces'] = TRUE;
            if (isset($_FILES['filePrdimage']['name'])) {
                $config['file_name'] = substr(md5(time()), 0, 28) . $_FILES['filePrdimage']['name'];
            }
            $this->load->library('upload', $config);
            if (!$this->upload->do_upload('filePrdimage')) {
                //no file uploaded or failed upload

我認為您應該只執行一項功能，以上傳具有數據數組作為參數的圖像，其中可以包含路徑和其他變量。

public function upload(array $data)
{
   $config['upload_path'] = isset($data['upload_path']) ? $data['upload_path'] : 'default/path';
   ...
   $this->load->library('upload', $config);       

   if (!$this->upload->do_upload($data['field')) {
      //no file uploaded or failed upload
      $error = array('error' => $this->upload->display_errors());
   } else {
      $dat = array('upload_data' => $this->upload->data());
      $this->resize($dat['upload_data']['full_path'], $data['upload_path'].$dat['upload_data']['file_name'],135,300);
     }
     ...
}

提交表單時，請檢查所有帶有$ _FILES全局變量的輸入字段，並在必要時調用上載函數，並為每個輸入字段設置上載數組$ data。
