[wp-hackers] Plugins: Best practice for conditional loading of actions and file includes

[Otto]

http://codex.wordpress.org/AJAX_in_Plugins

Basically, you want to make your javascript fire the request at
"admin_url('admin-ajax.php')". The request will need to include action
= 'some_special_action' in the POST.

Then you hook a function to wp_ajax_nopriv_some_special_action. The
function will get called for your action and it can get the stuff out
of the POST and act on it. Then it makes its own output and can call
exit or die to end the request quickly.

You *can* use the same sort of methods I describe in my earlier post,
but since there's special code for AJAX actions, you should use it
instead.
