kevinak Posted September 27, 2008 Share Posted September 27, 2008 Ok, I have a simple donation button on my site. When a success donation has occured, it transfers you to a thank you page, where it will add information to my database. How can I prevent a user from refreshing and adding more to the database without setting an actual limit to how many times they can donate? Is there a special ID system I can use so that they can only access the page once after they donate? Also, how can I pull the donation amount from paypal and put it into a php variable?

awpti Posted September 27, 2008 Share Posted September 27, 2008 You could always have it return to a script that adds the data and then THAT script can forward on to the thank you page..
