My code was from a module where impersonation recursively could happen, this is why I use a stack to save user state. I am also saving it to session and not using a static variable because I may uses batch functions.
But I see some problems right now: - To be safe impersonation should be saved into static variables (and "using session_save_session(FALSE);" ), so if anything goes wrong, $user is not afected. - If I want to be able to execute every Rules action in a batch, I need to change user "per action" Any idea of how to "inject" code before and after a rule action? 2013/1/21 Walt Daniels <wdli...@gmail.com> > We do the latter simple trick in our store code so we can show people the > member prices.
