Question

当表单成功填满时，我试图在我的上传功能上使用我的filemanager控制器上的重定向。

当我在表单的成功部分有redirect('filemanager')时，它会阻止多个文件上传，然后只上传一个。

但是当我像// redirect('filemanager')那样评论它时，我可以上传多张图片。

问题：我如何仍然在成功表单上使用我的重定向，但请确保上传所选的多个图片而不仅仅是一个。

控制器

<?php

class Filemanager extends CI_Controller {

    public function __construct() {
        parent::__construct();
        $this->load->library('upload');
    }

    public function index() {
        $data['title'] = 'File Manager';

        $data['template'] = 'template/common/filemanager_view';
        $this->load->view('template/common/template_view', $data);
    }

    public function upload() {

        $files = $_FILES;

        if ($files) {

            $cpt = count($_FILES['userfile']['name']);

            for($i=0; $i<$cpt; $i++) {           

                $_FILES['userfile']['name']= $files['userfile']['name'][$i];
                $_FILES['userfile']['type']= $files['userfile']['type'][$i];
                $_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
                $_FILES['userfile']['error']= $files['userfile']['error'][$i];
                $_FILES['userfile']['size']= $files['userfile']['size'][$i];  

                $url = '';

                $directory = $this->input->get('directory');

                if (isset($directory)) {
                    $url .= $directory . '/';
                } else {
                    $url .= '';
                }  

                $config['upload_path'] = FCPATH . 'images/catalog/' . $url;
                $config['allowed_types'] = 'gif|jpg|png';
                $config['max_size'] = 5000;
                $config['max_width'] = 0;
                $config['max_height'] = 0;
                $config['overwrite'] = TRUE;

                $this->upload->initialize($config);

                if (!$this->upload->do_upload()) {

                    // reminder todo some error code here

                } else {

                    redirect('filemanager');

                }
            }

        }

    }
}

由于@Vinie建议

，我现在已经开始工作了

<?php

class Filemanager extends CI_Controller {

    public function __construct() {

            }
        }

        $upload_errors = $this->upload->display_errors();

        if (isset($upload_errors)) {

            }

        } else {

            redirect('filemanager');

        }
    }
}
