groups_check_group_exists() - documentation/codex states parameter is group_id, whereas is actually group_slug

[rcain]

function groups_check_group_exists() - documentation/codex states parameter is group_id, whereas BP_Groups_Group::group_exists() (which it calls) actually requires group_slug

note: further issue - since this function actually (and usefully!) returns group_id given group_slug it should logically be renamed to eg: groups_get_id($group_slug) (ie. the converse of existing function groups_get_slug(group_id).

note: this refers to BP V 1.5.4 - not available yet on 'version' drop down on this ticket system.

This is a good suggestion.

The codex can be edited by anyone. If you see anything that should be changed, please correct it.

(In [5808]) Deprecates groups_check_group_exists() in favor of more aptly named groups_get_id(). Fixes #4023
