Ergh. Forgot one step.

Open includes/functions:
GO TO END BEFORE ?> AND ADD

PHP Code:

function create_ad()
    {
    global $DB_site;
    $sponsor = $DB_site->query("SELECT * FROM ads_sponsors ORDER BY RAND(NOW()) LIMIT 1");
    $sponsor = $DB_site->fetch_array($sponsor);
    return $sponsor;
    } 


You can call this add on any page by doing:

PHP Code:

$sponsors = create_ad(); 


and the referring to the field values of the database by $sponsors[id], $sponsors[sponsor], $sponsors[www], $sponsors[logo], $sponsors[clicks].

Hope that helps
