Creating a PayPal Payment Form
Although it can have some issues, PayPal does provide a very simple way to take payments on a website. And with a little tweaking you can easily turn a PayPal “Buy Now” button into a form where the user specifies how much they’d like to pay and what they are paying for.
PayPal makes doing this very easy by providing those “Buy Now” buttons you’ve probably seen around the place. Basically when you see one of those buttons, it is really the submit button on an HTML form with all the form fields set to hidden. This is fine for when you have a set price and set item, but what if you want the user to specify how much they are paying, and what they are paying for.
For example if you are adding a payment form to your freelancing site then you would want the client to type in their invoice number and the amount they wish to pay. This is easily done by changing the <input> fields from hidden to text and stripping away the defaults so that the user can fill them in. So let’s get started.
