我正在尝试创建一个简单的上传表单，将相关详细信息放入数据库中。我的数据库方面工作正常，但是当我尝试将文件移动到相关目标路径时，它失败并出现错误 500。
我已经检查了以下内容:
- 错误日志，没有显示任何错误
- 文件夹存在
- 文件夹权限正确，可写
任何人都可以帮我解决导致错误的问题吗？
谢谢。
编辑:重复插入和更新，并使用 $_FILES 而不是 $photos_uploaded 进行更新

最佳答案
这里缺少一个斜杠:
// No slash at the end
$target_path = '../' . $images_dir;
....
// No slash between path and file
$target_path = $target_path . $filename;
^^^^
应该是:
$target_path = $target_path .'/'. $filename;
