[RESOLVED] empty $_POST array when user exists in 'users' table

endlesse

I have a USERS table in mysql containing some test user data for my application.
I have a login form which submits to itself.
Here is basically the problem:

Whenever I try login using incorrect user/password, everything functions exactly as it should i.e. $_POST array contains expected vars: username, password, submit

Whenever I try login using correct user/password the $_POST array is empty!

All my user authentication is contained within an
if(isset($_POST['submit'])){
block of code, so it makes no sense at all that it could 'know' that these users are in the USERS table if it can't even enter this block of code?! It shouldn't care what user data I'm logging in with.

Could there be some phpMyAdmin issue?

Same thing happens when I try using GET.

I have debugged the code thoroughly and am about to give up after spending most of the weekend. Just thought I'd post here in case anyone had an idea or suggestion as to what might be going wrong. I've tried on both Firefox and Chrome.

Thanks for any replies.

Post the code.

Thanks for offering to help but the code would have been way too long to post.

Just to update I copied the site from my local WAMP over to a hosting site.
And instead of getting zero errors, it was showing an error about 'headers already sent'. The problem seemed to be with a header(location) I was using within a function to redirect to and from the login page. When I replaced this header/exit code with:

	echo "<script>document.location.href='{$location}'</script>";
	echo "<script>'Content-type: application/octet-stream'</script>";

everything worked!
Just posting it here in case it's helpful to someone else. I actually don't know what it does exactly that was different from the header command. I also don't know if this was definitely the problem as I was beginning to think it was some config issue, but when I tried the updated code again in my WAMP it also worked. So I'm just happy that it's now working 🙂
