   Hi,
   I am trying to write a plugin and I do not know how can I do it properly.

   The plugin I am working on requires the editing of the "get_forum_link" function, specifically the "$link " vatiable.

   I have the code done in php but do not know how to make a plugin out of it. What and how should I use add_action or add_filter?

   Thanx.

   function get_forum_link( $forum_id = 0, $page = 1 ) {
   global $forum;

   if ( $forum_id )
   $forum = get_forum( $forum_id );
   if ( bb_get_option( 'mod_rewrite' ) )
   $link = bb_get_option( 'uri' ) . "forum/$forum->forum_id" . ( 1 < $page ? "/page/$page" : '' );
   else {
   $args = array();
   $link = bb_get_option( 'uri' ) . 'forum.php';
   $args['id'] = $forum->forum_id;
   $args['page'] = 1 < $page ? $page : '';
   $link = add_query_arg( $args, $link );
   }

   return apply_filters( 'get_forum_link', $link, $forum->forum_id );
   }

   function my_get_forum_link_filter( $link ) {
       $link = 'yay'; // Whatever you want to do with the link
       return $link; // Very important line!
   }
   
   add_filter( 'get_forum_link', 'my_get_forum_link_filter' );

   That last line adds your custom filter function to the get_forum_link filters.

   Thanx.

   I do not know if I've did it right but it does not works. Am I doing something wrong?

   The new $link should be
   $link = bb_get_option('uri') . "$forum->forum_name" . ( 1 < $page ? "/page/$page" : '' );

   it all should look like:

   function my_get_forum_link_filter( $link ) {
   $link = bb_get_option('uri') . "$forum->forum_name" . ( 1 < $page ? "/page/$page" : '' );; // Whatever you want to do with the link
   return $link; // Very important line!
   }

   add_filter( 'get_forum_link', 'my_get_forum_link_filter' );
