Need help customizing URSP
How would I modify the files so that the registration/log-in system only worked for existing registered users? I am building a site for an organization that wants the current members to have access to members-only information and pages on the larger site. Visitors to the site would not have this additional access. I want to add the member information to the database tables that came with the solution pack. When these members registered on the site for the first time, the registration would recognize them and proceed implementing the process. Visitors that are non-members who tried to login would not be recognized in the database and the login would fail. I don't want it so that just anyone register in and automatically be added to the database tables and then have access to the members-only content. It seems like it would be possible to customize the solution pack in this way, but fairly new to working on dynamic sites and the URSP and need some advice and guidance. Thank you!
