PHP Prevent Form Submit Twice

[Gamerz]

Hey,

I currently have a file uploader.

 

I want to prevent a user from uploading the same files two times by making the page expire.

 

My uploader is currently running on ONE script. The form and the processing page is all in one script. Not two, but one.

 

And no, I don't want to use the location header redirection to prevent the user from uploading twice, because then, how is the user going to be able to know there file url?

 

I just want the page to expire once the upload is completed.

hello? seriously, no one knows how?

You could always use header('Location: '); and pass the url of their file in the query-string to get and display on a success page.

 

eg. header('Location: success.php?file=' . $file_url);

 

Then on success.php put something like:

if(isset($_GET['file']))
{
     echo "Your file was successfully uploaded! URL: " . $_GET['file'];
}

Is there any other way except header location? I also have way more variables to pass on. The delete file, the file url, the e-mail, the password...it would be a really long url to pass on that much variables...

you could set a session or cookie after they upload, and every time a user tries to upload check if the session/cookie is set

Use javascript to open a new window to show the FILE URL , then change top.location.href.

If the user refresh the page, PHP script will not be executed until the file  is uploaded.
