Kan je de code even tussen codetags zetten, en een link naar de door jouw gedownloade mod geven, want de mod op phpBBHacks.com klopt.

ik weet niet wat je bedoelt met codetags maar hier heb ik de mod vandaan http://phpbbhacks.com/download/237

Geplaatst: 29 mar 2006, 17:48
door Raimon
code tags zijn de tag

Code: Selecteer alles

 tekst [ / code] alleen aan elkaar schrijven.

Het staat er zeker op zie deze code:
[code]if (!$admin)
		{
			$sql = "UPDATE " . USERS_TABLE . " 
				SET user_session_time = $current_time, user_session_page = $page_id, user_lastvisit = $last_visit
				WHERE user_id = $user_id";
:wink:
