I have a project where I created 1000 qr codes for 1000 users. Each user has a unique profile that is updated.
So I have created 1000 user accounts (empty) that I have imported into the data base and that are ready to be used.
I need to know how to make sure that every time a user wants to register he can use one of the accounts not used by another user.
You could give each account a unique randomised number. So in the process of entering your account, they also need to enter that randomised number if you check if the number matches.
yes it’s a good idea you know, I created all the unique codes. Do you know how I should proceed afterwards?
Use the unique code to control registration:
- If the code entered matches and has not been used, then the user registers
- If the code entered does not match, then user can’t register
- If the code entered has already been used, then user can’t register
For each instance you can show an alert or message explaining what’s happening
I do, and it’s not hard. Take some time, and I’m sure you will figure it out.
Hello Charles,
I’ve been looking around for a while to find out how to do what you’ve explained to me but I don’t understand what I’m finding. Do you know where I can find your step by step advice? @charleshope
Hello, as @charleshope has mentioned, you can generate a random code that will be related to the QR code, and then you can use this code for registration.
Thank you!
The problem is that I don’t have to generate a code at registration but already have codes before the user registers
