我先是在本地做好的网站，本地测试正常，但是上传到服务器后，添加图片功能失败

$name=$upfile["name"];//上传文件的文件名
$type = @$upfile["type"];
$size = @$upfile["size"];
$tmp_name = @$upfile["tmp_name"];
switch ($type) {
case 'image/jpg' :$tp='.jpg';

}
$res = move_uploaded_file($tmp_name,'upload/'.$name);
$destination="upload/".$name;
include("conn.php");
if($res){
$sql = "INSERT INTO product (`cid` ,`cname` ,`cprice` ,`cspic` ,`cpicpath` )VALUES (NULL , '$cname', '$cprice', '', '$name')";
$result = mysqli_query($con,$sql);
$id = mysqli_insert_id($con);
echo "<script >location.href='menu.php'</script>";
}
?>
在服务器上其他功能都是可以完成的，本地也是可以运行的，只有在阿里云上这个运行失败。，有可能是上传图片方面的问题
