Load Forminator Form via Ajax

forminator-via-ajax-script.js

// This JS file is loaded by the theme:

(function() {
  // The button with the CSS class "get-support" loads the form.
  jQuery('.get-support').on('click', load_support_form);

  // The form is displayed in a div tag with the CSS class "support-form".
  function load_support_form() {
    jQuery.get('/wp-admin/admin-ajax.php?action=my_get_support')
    .then(function(response) {
      jQuery('.support-form').html(response.data);
    });
  }
})();

forminator-via-ajax.php

<?php
// The following Ajax handler is inside a loaded PHP file,
// such as a plugin, or in this sample, the functions.php file.

add_action('wp_ajax_my_get_support', 'ajax_my_get_support');

/**
 * Ajax handler that gernates the form with all 
 * required JS files and CSS rules.
 */
function ajax_my_get_support() {
  // Forminator needs the DOING_AJAX flag to 
  // correctly enqueue everything.

  }

  ob_start();
  echo do_shortcode('[forminator_form id="1234"]');

  // Add the JS files and inline styles, etc.
  // Since this is an ajax request, this should only 
  // output Forminator-related code.

Hey Phil,
This may be just what I need! My big question is (and I'm sure I'm missing something), if you have an "add_action" for "wp_ajax_my_get_support", doesn't there need to be a "do_action" also with the name "wp_ajax_my_get_support"? If so, where would that be, if not, why not?
Thanks for any help!
David

Be gentle...
...does the ajax call from the JS act as the "do_action" in this case?

Hey @dleigh - the wp_ajax_<action> hook is a special action provided by WordPress itself. You do not need to register an action with that name.

<?php
add_action('wp_ajax_my_get_support', 'ajax_my_get_support');

// You could also write it like this:
$js_action = 'my_get_support';
add_action('wp_ajax_' . $js_action, 'ajax_my_get_support');

The above action is called, when you make an HTTP request from your browser to the admin-ajax.php path and provide the action: "my_get_support" parameter. I.e. the following JavaScript line triggers that action for you:

...
// Note: The special endpoint "admin-ajax.php" and the action that is "my_get_support"
// The action MUST be identical with the $js_action value from the action name in PHP
jQuery.get('/wp-admin/admin-ajax.php?action=my_get_support')
...

Hopefully, this makes the connection between JS and PHP a bit clearer for you.

Also, you might want to check out the official documentation with a lot more details here:

@stracker-phil Thanks so much!!!
