I have this short code I am using to pass along the user id of the user who put entries in to my form.

add_shortcode('mx-check-if-friends','mx_friends_check_friendship');
function mx_friends_check_friendship( $atts ){
	extract(shortcode_atts(array(
		'possible_friend_id' => '',
	), $atts ) );
	global $current_user;
	get_currentuserinfo();
	$user_ID = $current_user->ID;
	return friends_check_friendship( $user_ID, $possible_friend_id );
}

To call it, I use: [mx-check-if-friends possible_friend_id=[88 show=”ID”]] where 88 is the field of the user who entered the data into the form. For some reason, this is returning the number 1 if it’s a friend or a blank if not a friend. Which is all good, but why is it not returning a True or a False?
