<?php | |
// embed the javascript file that handles the AJAX vodoo | |
wp_register_script( 'hip-ajax', plugin_dir_url( __FILE__ ) . '/ajax.js', array( 'jquery' ) ); | |
// declare the URL to the file that handles the AJAX request (wp-admin/admin-ajax.php) | |
wp_localize_script( 'hip-ajax', 'object', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) ); | |
wp_enqueue_script( 'hip-ajax'); | |
add_action( 'wp_ajax_my_action', 'my_action_callback' ); | |
add_action( 'wp_ajax_nopriv_my_action', 'my_action_callback' ); // for use outside admin | |
function my_action_callback(){ | |
$foobar = $_POST['foobar']; | |
// do stuff here, for example wp_update_meta | |
echo "something"; // will be 'response' in ajax.js | |
die(); // this is required to return a proper result | |
