I have a PHP registration form in the Mysql database. After completing the form, the user is redirected to the page cad.php where it says that the registration was made successfully and in 3 seconds it is redirected to login.
The problem is that if the user presses to return, PHP has to register again only with blank data, then creates a line without information.
I searched the internet about ignoring record with missing data, or the Not Null, but I was unsuccessful in the search.
even opening a Session if the user clicks back he would register again, wanted to type an "if name, email... not contain information, then redirect to home page"

Strange. Before entering records in the bank you do not check if the variables are empty? If you did that, no empty record would ever be entered in the bank.
