我必须在CodeIgniter中上传多个图像。 var_dump($_FILES)的结果是：

array

     array 
      'name' => 
      array 
       0 => string 'Best Wallpapers 2009 (Fun12.com) 01.jpg' (length=39) 
       1 => string 'Best Wallpapers 2009 (Fun12.com) 05.jpg' (length=39) 
      'type' => 
      array 
       0 => string 'image/jpeg' (length=10) 
       1 => string 'image/jpeg' (length=10) 
      'tmp_name' => 
      array

      'error' => 
      array 
       0 => int 0 
       1 => int 0 
      'size' => 
      array 
       0 => int 142036

为每个图像分别配置数组然后上传。像下面一样

//I have given an exmaple for one image repeat this for others, 
$config_image[0]['allowed_types'] = 'gif|jpg|png'; 
$config_image[0]['overwrite'] =TRUE; 
$config_image[0]['subcategory_image']['upload_path'] = './public/subcategory/'; 
$config_image[0]['subcategory_image']['file_name'] = $this->input->post('subcategory_name'); 


//Load and initialize the library as below and then upload 
$this->load->library('upload', $config_image[0]); 
$this->upload->initialize($config_image[0]);
