Looks like that function should have been defined somewhere.

It’s probably something like this:


function redirect_to($location, $status=302)
{
   header('Location: '.$location, true, $status);
   exit();
}

thanks scallio, i idefined it in the function as
<?php
//basic functions
function redirect_to( $location = NULL ) {
if ($location != NULL) {
header(“Location: {$location}”);
exit;
}
}

?>
and it worked.
