If you want to give people a hyperlink or image on your forum to make it easier for them to join a usergroup you can use the following

to join a group:

<form action="profile.php" method="post" id="foo">
<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="do" value="joingroup" />
<input type="hidden" name="usergroupid" value="X" />
</form>

Link

<a href="#" onclick="document.getElementById('foo').submit();return false;">Join Group X</a>

Image

<a href="#" onclick="document.getElementById('foo').submit();return false;">
<img src='imageurl.gif' width='50px' height='50px' alt=''>
</a>


And to leave the group:


<form action="profile.php" method="post" id="foo">
<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="do" value="leavegroup" />
<input type="hidden" name="usergroupid" value="X" />
</form>

Link

<a href="#" onclick="document.getElementById('foo').submit();return false;">Join Group X</a>

Image

<a href="#" onclick="document.getElementById('foo').submit();return false;">
<img src='imageurl.gif' width='50px' height='50px' alt=''>
</a>


Please remember, when using both forms, for joining and leaving a group in the same template you need to give either one a different ID ...

Demo :

http://ut2007world.com

Go to the navbar under Special Services you can see the links to either join or disjoin a usergroup which allows you to show the Spam Forums.

Credits going to Piglet (http://ut2004.titaninternet.co.uk) for helping out with the hyperlink.

If you rather want to use a submit button, use

to join the group:

<form action="profile.php" method="post">
<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="do" value="joingroup" />
<input type="hidden" name="usergroupid" value="X" />
<input type="submit" class="button" value="Join Group X" />
</form>


to leave the group:

<form action="profile.php" method="post">
<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="do" value="leavegroup" />
<input type="hidden" name="usergroupid" value="X" />
<input type="submit" class="button" value="Join Group X" />
</form>


I think I posted in the wrong forum, if so, please mod, move this one ;)
