I’ll probably end up trying to write this myself over the rest of the week but just in case a plugin guru is willing to help…

I’d like to exclude certain sub-forum topics from the latest discussions that are posted on the front page. I know how to tap into the list topics filter but I don’t know how to make it obey only for the front page, because obviously they can’t be excluded from the sub-forum’s own topic list when they are on that page.

In theory I could hack the template to do this but it would be much better via a plugin if possible. I can see other people wanting this feature eventually to help keep that front page list from becoming cluttered.

Ah nevermind – I already knew how to do this but was so tired I didn’t put 2 + 2 together. And a new plugin was born!

This plugin will either exclude ALL sub-forums from the front page topics list AND/OR exclude any specific forums from the front page that you specify.

function filter_front_page_topics($where){

// $exclude_forums=array ("8,1,3,12");   // enable this to manually specify specific forums by id #

$forums = get_forums(); foreach ($forums as $forum) {if  ($forum->forum_parent) {$exclude_forums[]=$forum->forum_id;}}  // exclude ALL sub-forums

if ( is_front() ) {foreach($exclude_forums as $forum) { $where.=" AND forum_id != ".$forum."  "; }}

return  $where;

}

add_filter( 'get_latest_topics_where', 'filter_front_page_topics');

add_filter( 'get_latest_posts_where', 'filter_front_page_topics');
