BUG? bp_the_body_class missing parameter

[tivnet]

This piece of code looks incorrect. $wp_classes does not have a default value, so the call bp_get_the_body_class(); should produce at least a warning.

function bp_the_body_class() {
	echo bp_get_the_body_class();
}
	function bp_get_the_body_class( $wp_classes, $custom_classes = false ) {

I'm not sure why we have a function bp_the_body_class() in the first place - the _get_ version should be all we need, since it filters another value, and is not meant to be called directly. In any case, you're current that we should either have a default value, or in bp_the_body_class() we should be passing a value for the first param.

In 7113:

Pass a default value to the first param of bp_get_the_body_class()

When bp_get_the_body_class() is run as a filter on 'body_class', the first
param is never empty. However, if you call the function directly, or in
particular if you call the echo wrapper bp_the_body_class(), you will get a
PHP error due to the fact that no default value for the function has been
provided. This changeset prevents any such errors.

Fixes #5025
