[RESOLVED] where should I place error message text?

[btumpak]

I am not sure where to place the error message text that I want to display (Please enter a valid ID).

Here is the snippet...

if ($sth->fetchColumn() <= 0) {
	// Invalid  ID
	exit;
}

instead of exit replace with

echo "Please enter a valid ID";

Thank you - that worked. How would I get this to redirect to a webpage instead of displaying the error message?

You use the header function

header("location:../target_page.php");
