我创建了一个包含 2 个文件上传字段的表单，基本上我想让它们成为必填字段。我创建了一个回调函数，但似乎无法使其正常工作。如果其他一些字段留空，它正在使用回调并发布错误，但无论文件是否附加都发送表单。我对 Codeigniter 很陌生。任何帮助将不胜感激！

控制器：

class Form extends CI_Controller {

function index()

    $this->load->helper(array('form', 'url'));

    $this->load->library('form_validation');

    //Upload errors array
    $up_errors = array();

    $this->form_validation->set_rules('first_name', 'First Name', 'required|alpha');

检查以下表单验证扩展，它可以帮助您验证文件，带有 CI 表单验证库的图像复制代码并在应用程序库中创建 MY_Form_validation.php 文件并将代码粘贴到该文件中并保存

表单文件验证
