If I am not mistaken you are looking for something that does the following:

-When the forum page loads it checks the ForumID.
-If the forum ID matches a specific command, it outputs X item.

If this is what you are looking for, this is just a simple if else function.

PHP Code:

<?php
if ($forumid = 1)
{
echo "Your desired output";
}
elseif ($forumid = 2)
{
echo "Desired output for 2";
}
else
{
echo "Desired output for FALSE";
}
?>
