People can come to my site, sign up, and their information is stored in a USERS table. They have a unique (auto-increment, primary key) id, username, first name, last name, etc. Now, I have a wishlist for them to fill out when logged in, which uses the table WISHES.
In my WISHES table, I want to store the user's unique id that is stored in the USERS table. What would I need to do to call the unique id from the USERS table, and put it in the WISHES table?
Thanks a lot in advance guys!
P.S: what is a unique key?
