Hello I'm new on this forum, I have a commercial project (a software with licence renovation every year), I want to every time I have a new client, register on a mysql database, so when the client pay (on paypal) a licence renovation after the payment redirect to a php login site, when the client get logged show a kind of validator where the client can type the renovation number to generate and show the unlock code at the same time automatically it is sent to the clients email, after that, if the user wants to log in again, show only the unlock code, until the client do a payment and show the validator again, and so on.. Is all this possible?
I already have a hosting with php and mysql database, but I don't have any knowledge on php, also I have no idea how to make the validator on a website, but It's based on math operations so I think it wont be a problem
