a simple example that will auto link a group slug mention in an activity update

this a proof == i’m lazy. so it only matches the group slug and NOT the true name (someone would have to build a function for that)

…and this uses a caret but anything can be used

function bp_activity_at_groupname_filter( $content ) {



//define your catch hook, i'm partial to the bang but lets eat a caret

$pattern = '/[\\^]+([A-Za-z0-9-_]+)/';

preg_match_all( $pattern, $content, $groupnames );



/* Make sure there's only one instance of each groupname */

if ( !$groupnames = array_unique( $groupnames[1] ) )

return $content;



foreach( (array)$groupnames as $groupname ) {



//note this is the group slug as for a proof - need to build a group "name" lookup function

if ( !$group_id = BP_Groups_Group::group_exists( $groupname ) )

continue;



//too much work to get a link

$thisgroup = new BP_Groups_Group( $group_id );



$content = str_replace( "^$groupname", "<a href='" . bp_get_group_permalink( $thisgroup ) . "' rel='nofollow'>^$groupname</a>", $content );

}



return $content;

}
