Show database information according to UserID
I probably have a rather easy question (shame on me that I can not figure it out) and apologize in case this was already covered (could not find anything in the forum).
Our website has a "Customer Only" area and I would like to display a "Dashboard" where, after signing in, they can post, update and delete information (recipes,images, etc). However, I of course only like them to have access to the information that this particular user/customer has posted. The information is usually in 2 different DB tables (the recipes for example that the user can insert are in the "Recipes" table of the DB and the User information for this particular user is in the "User" or "Member" table of the DB)
So somehow I guess I have to link or filter the results to the userID but have not figured this out yet.
Could you give me some pointers that even I as a beginner would understand?
Thanks a lot and best regards,
