I am trying to make an AJAX call for a plugin.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function($) {
    '<?php admin_url('admin-ajax.php'); ?>',
        action : 'AAA'
    function( response ) {
        alert( "[[[[" + response + "]]]]" );

The ajax call is working fine.

add_action( 'wp_ajax_nopriv_AAA', 'fAAA' );
add_action( 'wp_ajax_AAA', 'fAAA' );

function fAAA(){
      echo "123";

For some reason my fAAA is not getting called.

I used var_dump( $wp_filter['wp_ajax_nopriv_AAA'] ); to check the actions. * in the plugin, it showed that the action is added * when i looked in admin-ajax.php, the action is not there.

Any help?

Aside from @Tareq answer (which is your main problem), you should

  • wp_register_script and the wp_enqueue_script
  • load your local copy of jQuery instead of the one from Google CDN
  • localize your script using wp_localize_script

You didn't echo admin_url('admin-ajax.php')


You need to avoid using $ in wordpress, as by default, Wordpress runs jQuery in something called "no conflict" mode. I have learnt to keep to jQuery instead of $ when developing with Wordpress.

I don't know if it's your problem or not, as I'm browsing to find a fix for a problem of my own. You may even know this and be working around it. Apologies if so.

  • In this case, $ is passed as an argument to the function. This is one of the methods outlined in the wp_enqueue_script codex page and works correctly in WordPress.
