i found out why it wasn't displaying... it was filtering out the usergroup id's and unfortunately everyone doesnt have the same userids for there usergroups...
Code:
$lastsearches=$DB_site->query('SELECT searchid,postids,dateline,querystring FROM search LEFT JOIN user USING (userid) WHERE querystring!="" AND usergroupid NOT IN (5,6,7) ORDER BY searchid desc LIMIT 0,10');
see where it says 5,6,7? i changed it to 1 and it shows up...
how do you findout what ID each of your usergroups are?
