Hello all,

Two random question as I try to integerate Paypal IPN into my Codeigniter based web app.

1) Are these two lines the same?

$data['pp_info'] = $this->input->post();

$data['pp_info'] = $_POST;

2) A user agrees to pay a monthly recurring fee to use your service using paypal - first payment you are aware they have paid as you get data returned from paypal. But how do you keep track if users has paid for the following months? How do you know the user has not cancelled from their paypal account?

Thanks all for any help
