I have read other questions regarding the same issue but nothing seems to help in my case. Maybe someone sees something in my code that I cannot see?

I created a plugin with a class, then I have an AJAX call that triggers when I click on a HTML element on the page. All seems to work, except that it doesn't enter the callback inside the plugin.


class BSPFPluginClass {
  protected $nonce = 'mynonce';

  public function __construct() {
    /** other actions here ... */
    add_action( 'wp_enqueue_scripts', array( $this, 'myinit' ) );
    add_action( 'wp_ajax_myajaxcall', array( $this, 'myajaxcall' ) ); // executed when logged in
    add_action( 'wp_ajax_nopriv_myajaxcall', array( $this, 'bspf_ajax_voting' ) ); // executed when logged out

  public function myinit() {
    // Register the script
    wp_register_script( 'plugin-js', plugins_url( 'js/plugin.js', __FILE__ ), array() );

    if (is_page('somepage')) {
      // Enqueued script with localized data.
      wp_enqueue_script( 'plugin-js' );
      // Localize the script with new data
      wp_localize_script( 'plugin-js', 'plugin_ajax', [
        'ajax_url' => plugins_url( 'plugin.php', __FILE__ ), 
        'nonce'    => wp_create_nonce( $this->nonce ),

  public function myajaxcall() {
    check_ajax_referer( $this->nonce );
    if (true) {
      echo 'Yes it works!';
    else {
      echo 'No it does not work!';
    wp_die(); // stop executing script

Then, js/plugin.js

jQuery(document).ready(function($) {
  $(".myclass").click(function() {
    $.post(plugin_ajax.ajax_url, {
      _ajax_nonce: plugin_ajax.nonce,
      action: 'myajaxcall'
    }, function(response) {
      console.log('SUCCESS: '+response);
    }).done(function() {
    }).fail(function() {
    }).always(function() {

When I hit the HTML element with the trigger class everything goes well and I get the following on the console:


So it is like everything is correct, except is not entering the action 'myajaxcall'.

Any leads?

Thank you in advance.

    The ajax_url should be admin_url( 'admin-ajax.php' ) and not plugins_url( 'plugin.php', __FILE__ )

The ajax_url should be admin_url( 'admin-ajax.php' ) and not plugins_url( 'plugin.php', __FILE__ ) when you localize your js variables.

  • Thank you @Laxmana , actually, the AJAX is not for an admin page but rather a public page, so I don't see why I would need to add the admin_url( 'admin-ajax.php' )

    No. admin-ajax.php is a WordPress Core file that handles Ajax Requests. It's inside wp-admin folder. WordPress acts like a controller that handles Ajax requests and executes the appropriate action of the request. I suggest reading more about Ajax in WordPress here

    It doesn't matter if the Ajax call is being made from a public page or a admin page or even a different site. All Ajax calls should be made at admin-ajax.php for your hooked action to be executed.
