我有一个在本地安装中设计的应用程序（PHP4/MySQL），它运行得很好。自从我把它移到实时安装（PHP5/MySQL）后，我除了问题什么都没有！我在没有打开全局变量的情况下解决了任何全局变量问题（让我学习PDO，这不是一件坏事！），所以我唯一的问题是文件上传。我尝试了$_file的isset测试，但看起来变量从未设置过？有什么想法吗？
这是表单数据：
<form enctype="multipart/form-data" method="post" action="script_add_product.php" >
<input class="cp_forms_upload" type="file" name="full_image" />
<input class="cp_formsButton" type="submit" name="submit_button" value="Add Product" /></form>
这是PHP:
$full_image_url = $_FILES["full_image"]["name"];
if ((($_FILES["full_image"]["type"] == "image/gif")
|| ($_FILES["full_image"]["type"] == "image/jpeg")
|| ($_FILES["full_image"]["type"] == "image/pjpeg")
|| ($_FILES["full_image"]["type"] == "image/png"))
&& ($_FILES["full_image"]["size"] < 400000))
{
if ($_FILES["full_image"]["error"] > 0)
{
echo "Return Code: " . $_FILES["full_image"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["full_image"]["name"] . "<br />";
echo "Type: " . $_FILES["full_image"]["type"] . "<br />";
echo "Size: " . ($_FILES["full_image"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["full_image"]["tmp_name"] . "<br />";
if (file_exists("../Uploads/" . $_FILES["full_image"]["name"]))
{
echo $_FILES["full_image"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["full_image"]["tmp_name"],
"../Uploads/" . $_FILES["full_image"]["name"]);
echo "Stored in: " . "../Uploads/" . $_FILES["full_image"]["name"];
echo "<br /><br /><br />" . $full_image_url;
}
}
}
else
{
echo "Invalid file";
}
感谢各位：）
能否检查php.ini中的file_uploads是否设置为On。
; Whether to allow HTTP file uploads.
; http://ph .net/file-uplollow HTTP file uploads.
; http://php.net/file-uploads
file_uploads = On
请参阅php.ini配置。

upload_tmp_dir = "...../tmp"
; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 128M
此外，它可能是php.ini中有用的memory_limit和max_execution_time配置参数。更多：处理文件上传->常见陷阱
确保文件夹"../Uploads/"存在，并且有权在apache/nginx work（www_data或类似的）下为用户写入
这可能是问题所在吗？本节中的附加"（"括号：
if (($_FILES["full_image"]["type"] == "image/gif")
|| ($_FILES["full_image"]["type"] == "image/jpeg")
|| ($_FILES["full_image"]["type"] == "image/pjpeg")
|| ($_FILES["full_image"]["type"] == "image/png"))
&& ($_FILES["full_image"]["size"] < 400000))
