How to post form in ajax mode and handle it in wordpress

Question

currently I can only do it in a normal non-wordpress way.

So, does wordpress provide a solution for this circumstance?

Answer 1

It does, have you look at Bainternet's solution to this question and my answer to this question?

To summarise, you need to post the request to the WordPress' admin-ajax url. If the ajax is for use on the admin-side then this url should already be available as the javascript variable ajaxurl. If this is for use on the front-end then you'll want to get the admin url:

<?php echo admin_url('admin-ajax.php'); ?>

inside your javascript file (see my solution linked above). WordPress then files the following actions:

//for logged in users only 
add_action('wp_ajax_MY_ACTION', 'my_ajax_function');

//for non-logged in users 
add_action('wp_ajax_nopriv_MY_ACTION', 'my_ajax_function');

Where MY_ACTION is the action sent with the AJAX request. You can hook the function that deals with the request, (in this example my_ajax_function) onto the appropriate hook(s). This function should echo the response.
