I have built a bespoke site in Codeigniter and my client is getting orders through PayPal.
The problem that is happening is that I have written the site so that if a PayPal order is complete and returns back to the site, The booking gets updated to paid.
I have noticed that some orders, The customer is not returning to the site due sometimes the "Insecure Data" popup you get in most browsers.
I think, The way to resolve this is to make the return page an https:// page.
So am wondering how do you change the config in your CI to the https:// link on just that one page.
There may be other ways and am open to suggestions.
I am also considering the IPN route to update the order, But not too sure on that one.
Thanks
