Support » Everything else WordPress » Problem in .js file on call custom ajax.php

  • I’m developping a custom plugin to wp and I upload the files to “/wp-content/plugins/myplugin/” folder and activated it on dashboard.

    I’m having problem with javascript file to refers my custom ajax.php file.

    My javascript file “ajax.js” is locatted in “/wp-content/plugins/myplugin/js/ajax.js” that starts like this:

    var dataRecords = $(‘#recordListing’).DataTable({
    “lengthChange”: false,
    ‘processing’: true,
    ‘serverSide’: true,
    ‘serverMethod’: ‘post’,

    Maybe the problem is at “url:” and I tried differents URL’s parameters but no one works.

    My custom ajax file “ajax_action-myplugin.php” is located in root folder “/wp-content/plugins/myplugin/”.

    If you want your AJAX PHP code to use WP functions, you need to use the WP AJAX way.
    In your plugin’s main file, you should have

    add_action('wp_ajax_my_action', 'my_action_handler');
    add_action('wp_ajax_nopriv_my_action', 'my_nopriv_action_handler');

    and your action handler functions.

    As detailed at
    you also should output the location of the AJAX script from PHP, so your JS can get it. For WP way, that is admin_url( 'admin-ajax.php' ). If you aren’t using the WP way, you still want to load the script with the right URL using plugins_url( 'js/ajax.js', __FILE__ ).
