Need a Hack for users to sign Rules

[Itworx4me]

I need a hack for a signed rules page. When the members view the rules page they will have to sign the bottom of the rules in order to confirm they have read the rules. Have a button at the end of the rules for the member to click for verification. I would like to have this written to the database so I can see they have signed and read the rules. I think it is pretty easy. Still way knew at php for me to handle it. I hope someone can help out?

Thanks,
