Limit number of levels of threaded replies

[ousep]

Threaded replies, after a point, stop being usable. The textarea becomes too small to type in.

Punting this to 1.3

I'm about to commit a fix that works as follows. It adds a new function bp_activity_can_comment_reply() which, by default, always returns true. You can filter the output of that function to limit reply depth in the following way:

function test_comment_depth_limit( $can_comment, $comment ) {	
	if ( $comment->mptt_left > 3 )
		$can_comment = false;
	
	return $can_comment;
}
add_filter( 'bp_activity_can_comment_reply', 'test_comment_depth_limit', 10, 2 );

$comment->mptt_left refers the number of items to the left of the comment in the comment tree, including the original activity item. So this filter will limit comment depth to two levels (> 3).

(In [3491]) Adds bp_activity_can_comment_reply() function, allowing plugins to limit depth of activity comment threads. Fixes #1870
