Header already sent after form submission, I'm using a redirect to take my form elements to a new page to process them, but i'm getting the header Headers ALready Sent error and I cannot see why.
Is there an better cleaner way to do this?
if(isset($_POST["associate"])) {
$partner = $_POST['partner'];
$location = $_POST['location'];
$redirect = plugins_url() . "/myremovalsquote/inc/associate.php?partner=" . $partner . "&location=" . $location . "";
header('Location: '.$redirect);
} else {
echo 'Failed';
}
