Php If X = This Else = That

NewcastleFan · November 8, 2011

Hey guys, I've got a php form on a page called units.php, which submits to create.php (which has my if function in) I'm trying to get the page to display an error message on the original units.php page somewhere, preferably in a fixed div in the layout. At current I've included units.php in the create.php file and added the error above, however this floats the error message or complete message above my entire template, also breaks part of the site as it is on create.php in the address bar.

Is there a way to re-direct it back to units.php and add a error or complete message?

units.php:

<?php
session_start(); // start the session
if(!isset($_SESSION['user'])){
    // check if the user is logged in
    // the user is not logged in
    header("Location: login.php"); // take him/her to the login page
} ?>

<?php include ('mysql.php'); ?>
<?php include ('includes/functions.php'); ?>
