I need to add a check-in feature (very similar to foursquare check-in) in worpress based site.
There will be "Check in" button at the top of the web site, and clicking on it the visitor will be presented with a list of places.
Can somebody guide me to decide which one is more suitable for wordpress architecture?
i. Clicking the "Check-in" button, make an AJAX call and present the list of places as a modal dialog. ii. Clicking the "Check-in" button, present a Worpress page with list of places and a submit button.
Where should I host the server side API? Use Wordpress XML RPC or as a separate API application(May be on a different server and cross site AJAX call can be made via php-curl proxy)?
