我可以使用form_upload.php将项目添加到mysql服务器并在服务器文件夹上上传照片，但照片无法显示在view_data.php上。我已将文件权限设置为777，但仍然无效。
这是我的form_upload php和view_data.php：

答案 0 :(得分：1)
您的图片代码指向您的文件系统，需要指向一个网址：
<img src="/home/tz005/public_html/test/upload/filename' . $get_pic['filename'] . '"
您应该将其更改为：
<img src="/test/upload/'.$get_pic['filename'].'"
