function fieldgroup_edit_group_validate in Content Construction Kit (CCK) 6

Same name and namespace in other branches

1. 5 fieldgroup.module \fieldgroup_edit_group_validate()

Group name validation for programmatic group addition.

@todo Come back here and do the same thing for groups as we've done for fields, present a machine-readable name field as well as a label instead of trying to create a machine-readable name from the label.
