My need about plugin
When people become member of site [Url visible pour les membres Pro] , they become dynamically user/subscriber to paid course of [Url visible pour les membres Pro]
So when they subscribe to [Url visible pour les membres Pro] there is a dynamic connexion that create a user on [Url visible pour les membres Pro] with same email , same name , same forname used to subscribe to [Url visible pour les membres Pro] and creation of automatic password for access to [Url visible pour les membres Pro] an email is send with those informations
i need, for each user, of site [Url visible pour les membres Pro] creation of a new data in Database that can be on or off
when it is on, access to course annee 1 A , annee 1 B, annee 2 , annee 3, annee 4 are open to user
when it is off , only access to course annee 1 A ([Url visible pour les membres Pro])
