I have trying to sett session using
this way is work, but I don't sure are this is the correct way for creating session?
so I wanna to get this session to displaying in form action
how to get session back?
and after error session displayed, I want to unset this session, where I can unset this session?
I wanna to using method = "post" in form without a duplicating possible entry if I refresh page after inserted.
