jQuery empty() doesn't tell you if something is blank, it tells you whether something is truly empty - having no other nodes inside it. This function tells whether a string is blank. It returns true in cases where there are no printable text characters are in the string.
function isBlank(str){
return str.replace(/\W/gi, '') == '';
}

Last active March 13, 2018 20:24 — forked from briancollins/StripeTutorialPage.html
I really hate seeing "examples" that contain accessibility errors, esp. when they're so easy to fix. This forks a tutorial for the Stripe API and makes some relatively minor adjustments to make it much more accessible. Still not perfect but way better than the original.

This snippet allows you require a user be logged into Wordpress in order to access non-WP content. For instance, imagine you have another section of your site that isn't part of Wordpress but still requires the user to be authenticated. Using this code, you can share the Wordpress authentication for that part of the site as well. Add this snippe…
<?php
// If your Wordpress blog isn't in the document root,
// you may have to change the path to wherever the
// Wordpress root directory
require($_SERVER['DOCUMENT_ROOT'].'/wp-blog-header.php');
// if the user isn't logged in, this will redirect them
// to the login page. On successful login it will redirect
// them to the page this code is currently in.
if(FALSE === is_user_logged_in()){
