Someone who has worked with Cubecart 4 code. I want this functionality.
Using the API [login to view URL] just detect if the user is from AUS or NZ using the IP address and if he/she isn't then display a lightbox style popup saying "You do not seem to be from Australia or New Zealand. We only ship to these countries, please try one of these sites" and display some google adwords within the popup. There should be a button in this lightbox effect modal popup labelled "No thanks I wish to continue browsing this store" to dismiss the popup. The popup must use the $_SESSION to keep track of whether it has been displayed before or not. It must also use the isSearchEngine functionality that cubecart has to detect whether the user is a search engine. Ofcourse the modal popup should only appear if it is a real user.
You will need to download you own version of CC4 and make these changes, and then provide me with only the files you modified. I will perform a code review and if necessary get you to fix any issues/concerns.
If you do a good job and write clean code and well tested, I will have more jobs for you.
