我正在尝试设置一个上传站点，但无法获得上传文件的脚本。（上传文件夹的所有权限都设置为777。）我继续收到这些错误：
Warning: move_uploaded_file(/var/chroot/home/content/44/9976344/html/tech/filemanager/uploads/Ace_planning_instructions.docx) [function.move-uploaded-file]: failed to open stream: No such file or directory in /home/content/44/9976344/html/tech/tech/js/upload.php on line 72
Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpo89pGR' to '/var/chroot/home/content/44/9976344/html/tech/filemanager/uploads/Ace_planning_instructions.docx' in /home/content/44/9976344/html/tech/tech/js/upload.php on line 72
Error! Most likely upload directory doesn't have writable permissions or you didn't set it up correctly.
我可以做些什么来修复或解决这些错误？
这是我的代码：

据我所见，您正在将上传复制到错误的目录"/var/chroot/home/content/44/9976344/html/tech/filemanager/uploads/"one_answers"/home/contant/44/997644/html/tech-filemanager/uploads/"不相同，如果其中一个是符号链接（很可能）。使用路径"/home/content/44/9976344/html/tech/filemanager/uploads/"，而不是使用路径"/var/chroot/home/contant/44/997644/html/tech-filemanager/uploads/"。符号链接只包含有关其链接到的文件的信息。
