Add custom vat field to woocommerce emails

I am really stuck and have tried every email hook under the sun. I used an outdated PHP code developed by someone else and revised it for new woocommerce hooks (as the code is 4years old). Everything works perfectly but i need the customer field "billing_vat" to appear in the new order admin email. I will share my code and any help will be greatly appreciated please!!
Thanks

Shortly after posting this, i found a fix for it. I had to define the new key "billing_vat" so that it posted with other user information. All the code above is correct except the last add_filter hook. Replace that with the following code, and you have added an optional vat_number field to your checkout, admin backend as well as order emails. Here's the code snippet to replace last "add_filter" hook:
// VAT Number in emails
add_filter( 'woocommerce_email_order_meta_keys',
'supine_vat_number_display_email' );
function supine_vat_number_display_email( $keys ) {
$keys['VAT Number'] = '_billing_vat';
return $keys;
}
code goes in functions.php of your active child theme. Tested and working.

2 different php scripts 2 different logins. How can I make one login?

I have 2 PHP scripts, each have their own register and login forms. I want to be able to take the user information from one and use it on the other so that my members do not have to register or login on the second PHP script. Below is the login, register and logout functions for both scripts
This is PHP script #1 where I already have members:

How do I add a background/highlight color to specific words in a Wordpress Chatroom plugin?

Outline-
I am running a Wordpress v4 installation and have installed a chatroom plugin: https://github.com/wp-plugins/chat-room (full code below).
I want to be able to highlight specific words that appear in chat when a user posts a message. For example, every time a user posts a message with the word "Dog" in it, it would have background colour so that it can be highlighted to everyone.
As the HTML output from the plugin is plain HTML, the best solution I have found is the following working example: https://jsfiddle.net/4ny8adpg/2/.
The Problem-
When using the script from the jsfiddle above on the page where the chatroom is placed, it seems that the script either cannot find the words or cannot replace them. I do not understand why, as the HTML that is output from the chatroom scripts is plain HTML (exactly as shown in the jsfiddle). It's also worth noting that the script will find and replace words that are written into the HTML source on the same page.
The Code-
Below is the PHP, Javascript and example HTML output for the chat-room plugin. I did not write this plugin and the original author offers very very limited support.

Highlighting words in Javascript - Why won't they stay highlighted after the page fully loads?

So this is a question following on from the awesome work #Drakes has done on this question previously: Highlighting words with Javascript, what am I missing?.
The solution is to highlight words by finding "#cat" or "#dog" and replacing them with
<span class='cat'>#CAT</span>
or
<span class='dog'>#DOG</span>
Then we can control the background colour of the span tag with CSS.
This works perfectly, however the background colour only remains for a brief moment before disappearing. Upon a closer look, it seems the span tags are applied correctly and then removed again suddenly.
Here is the actual working example for you to have a look at, plus log in details to run any tests and to view the chat.
[Removed, no longer exists]
Below is the updated code from the previous question that is currently running on the working example.
Once again, any further help is hugely appreciated. Please let me know if you require any additional information!

// NOTE: I needed to define these variables to make the demo work
var ajaxurl = "http://ip.jsontest.com/";
var chatroom_slug = "1";
var last_update_id = "1";
var last_update_received = 0;
function chatroom_check_updates() {
jQuery.post(
ajaxurl,

chatroom_slug: chatroom_slug,
last_update_id: last_update_id

function (response) {
// NOTE: the response is bad, an exception will be thrown, not NULL
chats = null;
try {
chats = jQuery.parseJSON( response );
} catch(e) {}
// NOTE: In this test, I don't know your URL, so I just commented out the bit below
if (1 || chats !== null ) {
for ( i = 0; i < chats.length; i++ ) {
if ( jQuery('div.chat-container div.chat-message-'+chats[i].id).length )
continue;
jQuery('div.chat-container').html( jQuery('div.chat-container').html() + chatroom_strip_slashes(chats[i].html) );
last_update_id = chats[i].id;
jQuery('div.chat-container').animate({ scrollTop: jQuery('div.chat-container')[0].scrollHeight - jQuery('div.chat-container').height() }, 100);
}

var hashtag = jQuery(this).text()

Example HTML output:
<div class="chat-container">
<div class="chat chat-message-111"><strong style="color: #840;">User 1</strong>: What is your favourite animal?</div>
<div class="chat chat-message-112"><strong style="color: #840;">User 2</strong>: I vote for #dog. </div>
<div class="chat chat-message-113"><strong style="color: #840;">User 3</strong>: I have a #cat!</div>
</div>

Because you are replacing all the text even if there is not a match. So .text() strips the HTML and than it does not find dog or cat and just puts the text in.
var hashtag = jQuery(this).text()
.replace(/#dog/g, "<span class='dog'>#DOG</span>")
.replace(/#cat/g, "<span class='cat'>#CAT</span>");
jQuery(this).html(hashtag);
since you replace #dog with #DOG it will not match since the search is not case insensitive
either make it case insensitive
/#dog/gi
or only replace the text if there is a change made.
var orgText = jQuery(this).text();
var hashtag = orgText
.replace(/#dog/g, "<span class='dog'>#DOG</span>")
.replace(/#cat/g, "<span class='cat'>#CAT</span>");
if(orgText!==hashtag) {
jQuery(this).html(hashtag);
}
Note: the way you have it currently written, you are going to blow away the User formatting since you are reading the text.

How can I call an on page PHP function by pressing a button?

<?php
// Edit this ->
define( 'MQ_SERVER_ADDR', 'XX.XXX.XXX.XXX' );
define( 'MQ_SERVER_PORT', 25565 );
define( 'MQ_TIMEOUT', 1 );
// Edit this <-
// Display everything in browser, because some people can't look in logs for errors
Error_Reporting( E_ALL | E_STRICT );
Ini_Set( 'display_errors', true );
require __DIR__ . '/status/MinecraftQuery.class.php';
$Timer = MicroTime( true );
$Query = new MinecraftQuery( );
try
{
$Query->Connect( MQ_SERVER_ADDR, MQ_SERVER_PORT, MQ_TIMEOUT );
}
catch( MinecraftQueryException $e )
{
$Exception = $e;
}
$Timer = Number_Format( MicroTime( true ) - $Timer, 4, '.', '' );
?>
<link href="css/bootstrap.css" rel="stylesheet" media="screen">
<div class="spanx"><p>
<h1>Login</h1>
Username:<br />
<input type="text" name="username" style="height: 30px; style="width: 220px; value="" />
<br/>
<button>Submit</button>
<?php // Example from PHP.net
$string = '<?php if( ( $Players = $Query->GetPlayers( ) ) !== false ): ?>
<?php foreach( $Players as $Player ): ?>';
if(stristr($string, 'Thisshouldbethestringfromthetextbox') === FALSE) {
echo 'Player is not online';
}
?>
Is my code. Basically what I am trying to do is query my Minecraft server. Check if a player is online by the text form on button click, and if not, deliver a message that says the player is not online, otherwise, keep the person logged in as they browse the site (dunno how to do this either...)
The external query file is:
<?php
class MinecraftQueryException extends Exception
{
// Exception thrown by MinecraftQuery class
}
class MinecraftQuery
{

I would like to solve this in any way that I can. Thanks in advance and ask any questions you need :D.

You can create a form pointing to the same URL to accomplish that.
<form action="<?= $_SERVER['REQUEST_URI'] ?>" method="post">
Username: <input type="text" name="username" />
<button type="submit">Send</button>
</form>
When the form is sent, you can access your input content by accessing $_POST['username']
if (isset($_POST['username'])) {
// your code here
echo 'Username: ' . $_POST['username'];
}
