my CI 2.x.x based app should have an express开发者_StackOverflow社区 checkout button, what's the best way to approach this? is there a ready made thing to implement it without having to write a long file of php code? , the whole paypal api seem very huge for me to read to just implement a simple checkout process in a small project
you can use the existing Codeigniter PayPal Library.
