How do I collect player emails

Hey smarter people than me,

I am building a game for a non profit, and I'm wondering if it's possible to have a scenario where a player can put in their email address to get free coins, turn off ads etc.

thanks!

It's absolutely possible, but if you've never done this before it's not exactly an easy task. The gist is:

1. You create a textbox input for the email
2. You send whatever is in the textbox to a server via AJAX

There's a bunch of things to think about, like what if the player types in "asfdsagsdafdsafdsafds" and sends it? What do you do with it once it's on the server? A database perhaps? What if a player is evil and starts an SQL injection attack? What about privacy and stuff? Not to mention each question has more than one solution.

There are two tasks here - sending information to some server, and receiving information about player status (free coins, no ads etc.)

If you need a proper solution, you will have to set up a database on your private server, or use some service like Firebase.

If it's a simple game and you don't care much about people cheating, you can send their email to a Google spreadsheet and just immediately give them free coins for doing that.
