I have a page with a basic form with <form name="myform" action="submit.php" method="post">
The submit.php page just shows a loading ajax image and says, "we will take you there in one moment" and does some other stuff in the background.
The page then does a html meta redirect after some seconds to take the user to the final, off-domain page.
The data from the Form on the first page needs to be passed on to the redirecting URL. Since the form includes a password field, I don't want to append the data to the redirect URL.
Is there a way to do this?
You can simply add the form data as GET variables on your redirect URL like this:
header("Location: http://example.com?password=".$_POST['password']);
You could encrypt the data using various methods such as md5.
If you don't want to use a GET, then you'll have to use a POST, which means you'd have to use CURL to send the data to the other page, separately to your redirect.
