        array

每个图像都有一个单独的配置数组，然后上传。像下面

//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]);
