PHP and iUI

jarv · July 24, 2010

hi,

I have recently got into iUI from watching the Joe Hewitt video here: http://uk.video.yahoo.com/watch/853528/3491272

so far, I have managed to, from a normal login page go to a list of pubs taken from my database.

My problem is when you touch/click on View More at the bottom of the list, this should show 20 more results, which it does but they are the same results, I need to build a query string of the next 20 results then the next 20 and so on...

here is my current code:

<?php
include_once("config.php");
include_once("functions.php");
// Check user logged in already:
checkLoggedIn("yes");
//doCSS(); ?>
