Question

我正在尝试使用CodeIgniter的上传库，但我一直在收到错误：

A PHP Error was encountered

Severity: Warning

Message: strrpos() expects parameter 1 to be string, array given

Filename: libraries/Upload.php

Line Number: 1178

Backtrace:

File: C:\xampp\htdocs\schoolPortal\application\controllers\StudentAffairs.php
Line: 207
Function: do_upload

File: C:\xampp\htdocs\schoolPortal\index.php
Line: 292
Function: require_once

我不知道错误是什么，因为我只是在相同控制器的其他功能中复制了相同的代码，但是那个正在运行。

以下是控制器中代码的示例：

            $img_name = $this->InfoModel->getFirstNullAnnouncement();

            $config['upload_path']          = './images/';
            $config['allowed_types']        = 'gif|jpg|png';
            $config['max_size']             = 5000;
            $config['max_width']            = 3000;
            $config['max_height']           = 4000;
            $config['overwrite']            = TRUE;
            $config['file_name']            = $img_name;

            $this->load->library('upload', $config);
            $this->upload->initialize($config);

            $img = "userfile";

            $id = $this->session->userdata('id');
            $user['user'] = $this->UsersModel->select_student_affairs($id);

            if (!$this->upload->do_upload($img)){
                $data['error'] = $this->upload->display_errors();

                $this->load->view('include/header_student_affairs',$user);
                $this->load->view('studentaffairs/add_announcement', $data);
                $this->load->view('include/footer_student_affairs');
            } else {
                $img_path = 'images/'.$this->upload->data('orig_name');
                $data['success'] = 'Announcement has been updated.';
                $data['announcements'] = $this->InfoModel->getAnnouncements();
                $data['announcenum'] = $this->InfoModel->getAnnouncementCount();

                $this->InfoModel->updateAnnouncement($img_path);

                $imgdata = $this->upload->data();
                $thumbnail = $imgdata['raw_name'].'_thumb'.$imgdata['file_ext'];
                $this->createThumbnail($img_path, $img_id, $thumbnail);

                $this->load->view('include/header_student_affairs',$user);
                $this->load->view('studentaffairs/announcements', $data);
                $this->load->view('include/footer_student_affairs');
            }

第207行就是这个：

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

$this->upload->display_errors();会产生错误：T he filetype you are attempting to upload is not allowed.

请帮忙

Answer 1

也许您要上传的文件的扩展名为.jpeg，而$config['allowed_types']列表中没有该文件。

strrpos（）期望参数1是字符串，给定数组
