IP Locator not working with Cloudflare

Question

I have set up an IP Locator service. Worked fine, until I started using Cloudflare:

Instead of showing the user's IP address, Cloudflare shows its server's IP! What can I do?

My Site: http://nix-pix.co.uk/ip

Note: I'm on a shared server, so I cannot do any server-side modifications

Answer 1

This can be fixed in one of several ways:

In PHP, Cloudflare reports the real IP addresses like this: $_SERVER["HTTP_CF_CONNECTING_IP"];

For a server-side solution, you can install a module which will automatically resolve the correct IP. https://www.cloudflare.com/wiki/Log_Files
