hello friends I am developing a web application to connect to a mariaDb database. I have 04 tables (table 1, table 2, table 3, table 4)
to have access to the first table I made a coinnection form but my problem is that if a person knows the link of table 2 he can display it. I want to force everyone to connect before having access to my web application... is this method possible?
