问题描述
当尝试保存使用GD制作的缩略图时
When trying to save a thumbnail made with GD
imagejpeg($tnImage, "../../img/thumbs/".$maxWidth."x".$maxHeight."_".$filename);
我遇到以下错误:
警告:imagejpeg()[function.imagejpeg]:无法打开"../../img/thumbs/80x80_55865-drops.jpg"进行写入: /home/user/workspace/stewart/server-side/libImg.php
Warning: imagejpeg() [function.imagejpeg]: Unable to open '../../img/thumbs/80x80_55865-drops.jpg' for writing: No such file or directory in /home/user/workspace/stewart/server-side/libImg.php
/home/user/workspace/img/thumbs的权限设置为0x777.
/home/user/workspace/img/thumbs has its permissions set to 0x777.
这有什么问题吗?
推荐答案
您从哪里运行文件?如果它来自server-side目录，那么我认为您缺少"../"
Where are you running the file from? If it's from the server-side directory then I think you're missing a "../"
尝试一下:
var_dump(realpath("../../img/thumbs/".$maxWidth."x".$maxHeight."_".$filename));
