Create a wildcard domain cookie when a Popup Maker popup opens

create_wildcard_domain_cookie.php

<?php // Ignore this first line when copying to your child theme's functions.php file.

/**
 * This filter adds custom jQuery to the footer of your posts and pages to open a popup
 * with a cookie. 
 *
 * The jQuery does 2 things:
 *
 * 1) It checks if the cookie exists. If it doesn't, the popup will launch after a delay.
 *
 * 2) It listens when a specific popup opens and creates a cookie that uses a "wildcard"
 * domain so that your base domain and subdomains of your site can access the cookie.
 *
 * This code handy if you have a popup that you want everyone to see only once, but you
 * have that popup on your base site (mycoolsite.com) and subdomain sites (e.g., www.mycoolsite.com,
 * blog.mycoolsite.com, shop.mycoolsite.com).
 *
 * If you use this, make sure you don't create a cookie in your popup trigger settings.
