Wait stop, no hates! I know I can create a simple paypal donate button. However, I'm aiming for something just a tad different. For a site I'm making for my girlfriend, she wants to have a button that when you click it, it brings up a box next to it. It has four optional fixed donations (buy me a soda - 1$, buy me lunch - 5$, buy me dinner - 10$, and take me to the movies 20$), as well as a box where you can enter a custom donation amount.
How I'm planning on achieving this is having a javascript create a box when you mouse over or click the image (not sure which I'll do). There will be a radiobutton next to the images for the fixed donation prices and for the custom donation. For the custom donation, I'm going to have a field next to it's radiobutton where they can enter the amount. At the bottom, you can click the "donate" button.
The help I need is this: where in a paypal donate code can I enter arguments? The paypal donate button I've generated is all encrypted. Also, how would I update the URL a button points to every time the radio button changes (and of course, the custom field whenever it's changed) I'll really appreciate anyone who can figure this out! thanks!
