我想在我的主页上传图片。我正在使用w3schools编写的脚本来执行此操作：

这是upload.html

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

我是php的初学者，不知道问题出在哪里。也许有人能帮我解决这个问题。：）

通过在命令行执行以下操作，检查是否可以上载文件：

chmod-R 777/var/www/uploads/

然后试着上传一些东西。如果这样做有效，您就知道这是一个权限问题。但您不想将uploads文件夹保留在777权限（这将允许所有人访问）

如果是权限问题，下面是我喜欢的权限处理方式：

chown[您的用户名]：www-data-R/var/www/uploads/

chmod-R 775/var/www/uploads/

这会将文件夹的组分配更改为www数据，这通常是apache在Ubuntu linux服务器上运行的方式。

您对“/var/www/uploads/”文件夹的权限是什么，它需要由您的Web服务器用户拥有或可写，最常见的是www-data或apacheMake确保“/var/www/uploads/”的权限设置为

您的

move\u uploads\u file

函数返回false。如果文件不是有效的上载文件，或者文件是有效的上载文件，但由于某些原因无法移动，则会发生这种情况。检查您对要上载到的文件夹的权限。也许你需要确保你有读写权限。我在哪里可以更改文件夹的权限？服务器在Debian 7上运行。编辑：刚刚在Filezilla上找到它。但问题仍然存在。你有菲利齐拉吗？只需右键单击文件夹并选择权限，然后键入755

File is an image - image/jpeg.
Sorry, there was an error uploading your file.
