Custom function to pass in a jQuery script to set a cookie via manual JS during 'on_click' trigger event and on form close.

Set Cookie on Form Submit and Close

<?php

add_action( 'wp_footer', 'my_custom_popup_scripts', 500 );

function my_custom_popup_scripts() { ?>
<script type="text/javascript">
      (function ($, document, undefined) {
        
          jQuery('#pum-1483').trigger('pumSetCookie');
        
          setTimeout(function () {
              PUM.close(1483);
          }, 5000); // 5 seconds
        
      }(jQuery, document))
</script><?php
}

@Samuroid - Doesn't WPML have a language switcher shortcode? It uses cookies & URL's to save state already and changes the current URL. Could that not do the trick?

Alternatively, you will have to remap the URL to the new language when they choose it via JavaScript string manipulations before redirecting.

With current Popup Maker plugin I had to use this:

const popupElement = document.querySelector('#pum-<id> or .pum class');
PUM.setCookie(popupElement);
// (or window.PUM)

@strarsis the the popupElement you pass in gets passed to PUM.getPopup(). That is a magic function of sorts and will accept an element, a numeric ID #, or a selector. So you could probably shortcut and just do PUM.setCookie(<id>) similar to the example aboves PUM.close(1483)
