Upload Form Loses Data!

[RTS]

So I have a simple PHP upload form ( The code below ), that uploads to a folder called files. The problem is that every file that is uploaded doesn't work any more when uploaded in files. How can I fix this?
[code]<?PHP

$target_path = "files/";

$target_path = $target_path . basename( $_FILES['Filedata']['name']);



if(move_uploaded_file($_FILES['Filedata']['tmp_name'], $target_path))

{

    echo "The file ". basename( $_FILES['Filedata']['name']). " has been uploaded";

}

else

{

    echo "There was an error uploading the file, please try again!";

}

?>

[/code]

are you sure the form has the enctype="multipart/form-data" attribute?

[RTS]

This is probably a permissions problem with the folder. What type of files are these and what exactly do you mean - [quote]every file that is uploaded doesn't work any more[/quote]

I have chmoded the folder to 777, and the files that I have tried uploading are swf, and avi files as these are the types my site will be working with.

correct me if i'm wrong, but if I remember correctly, the maximum allowed filesize is 2Mb. If your files go beond that, they wont be uploaded unless you edit your php.ini to allow bigger filesizes.

they are smaller thann 2mb tho like 500 kb

Not a problem with your variables is it?
On an old web server of mine I had to request the file names and such using

$filedata = $_REQUEST['filedata'];

.etc

But if your variables are fine then I'm not sure what the problem may be.
