我看了网站找到解决我问题的方法，但找不到答案。希望有人可以帮助我：
我有一个脚本可以在没有pagerefresh的情况下上传和调整图像大小。我在互联网上找到它并调整它以供我使用。该脚本可以在下面找到。
我的问题：
首先upload.php脚本有效，但知道我得到错误号9。
我自己尝试解决这个问题：
有人可以提前帮助我吗

答案 0 :(得分：2)
尝试删除此行中的@：
if(!@imagejpeg($im,$dir.$file,100)){
它抑制了imagejpeg抛出的错误。没有它，你可能会看到你的问题。
答案 1 :(得分：0)
从以下行中删除@：
if(!@imagejpeg($im,$dir.$file,100)){
@可以抑制错误。如果它已被删除且display_errors已启用，您应该会看到更具描述性的错误消息。
我的猜测是，由于权限不足，imagejpeg()无法写入文件。
答案 2 :(得分：0)
该死，
我很蠢:(
如我所知，我删除了@并亲眼看到了我做错了什么。
错误发生在我的目录结构中，就像这样
| mainFolder | | _ |子文件夹| | upload.php的 | | imageFolder |
$dir = $_POST['uploadPath'];是一个将文件移动到“mainfolder / subfolder / imageFolder”的文件夹，但它需要是“imageFolder /”，因为我在“子文件夹”中使用了upload.php文件。
感谢您的所有帮助
