x amount of posts to start new thread in forum

[PennylessZ28]

I have a "Classifieds" section on my forum, and we have been having a problem with 1 posters just placing thier ad on our forum. My members dont' like this becuase they worry.

And personally we think of it as spamming. We are a local forum for our state, so when someone from CA signs up just to post thier car for sale its annoying and spam.

We would like to limit it so the user need X amount of posts to be able to post in the classified section.

I searched and found one thread on the subject, but it was for vb 2

I have used the following code with a little sucess

if ($bbuserinfo[usergroupid]==X AND $bbuserinfo[posts]<Y AND $foruminfo[forumid]==Z)
{
show_nopermission();exit;
}

However the placement of the code in VB 2 is different than in VB 3.

So I kinda just took a random guess, it almost works, the new user can post anywhere, but when he posts in the Z forum the following message is displayed

PHP Code:

Fatal error: Call to undefined function show_nopermission() in /disk3/home2/web/beginner/fbody/newthread.php on line 301 


I placed my code snipet in newthread.php

Can anyone provide me with some advice?
