pre_comment_approved filter has second argument undefined

[laotse]

I wrote a filter:

function tgb_comment_filter_approved($mApproved, $aCommentData){ ... }
add_filter('pre_comment_approved', 'tgb_comment_filter_approved');

and $aCommentData is always undefined. So effectively the changeset 15592 fixing #14802 does not work.

You must specifically add the filter asking for 2 arguements to be passed.:

add_filter($action, $function, $priority=10, $number_of_args=1);

So you want:

add_filter('pre_comment_approved', 'tgb_comment_filter_approved', 10, 2);
