bp_blogs_record_comment throws PHP warning when moderating comment

[needle]

Line 240 of 'wp-content/plugins/buddypress/bp-blogs/bp-blogs-functions.php' throws a PHP warning when a comment is posted by someone not logged in. Existing code:

$user    = get_user_by( 'email', $recorded_comment->comment_author_email );
$user_id = (int)$user->ID;

$user is not defined when commenter is not logged in, so an extra check is needed before accessing the ID property. Something like the following should fix this:

$user_id = (int) ( is_object($user) AND isset($user->ID) ) ? $user->ID : 0 );

Cheers,

Christian

Proposed patch, a bit changed logic flow.

Looks good.

(In [5899]) Rearranges logic in bp_blogs_record_comment() to avoid PHP notices when a post is left by a non-logged-in user. Fixes #4068. Props Mamaduka
