Add Referrer to WooCommerce order

woocommerce-order-referrer.php

<?php
// Set cookie for new users
add_action( 'init', 'set_newuser_cookie'); // Run when WordPress loads
function set_newuser_cookie() {
	
	$cookie_value = $_SERVER["HTTP_REFERER"]; // Get URL the user came to your site for
	
	if ( !is_admin() && !isset($_COOKIE['origin'])) { // If not an admin or if cookie doesn't exist already
		setcookie( 'origin', $cookie_value, time()+3600*24*30, COOKIEPATH, COOKIE_DOMAIN, false); // Set cookie for 30 days
	}
}


// Check cookie when order made and add to order
add_action('woocommerce_checkout_update_order_meta', 'add_referral_meta'); // Run when an order is made in WooCommerce

function add_referral_meta( $order_id, $posted ){
	$ref_url = $_COOKIE['origin']; // Get the cookie
    update_post_meta( $order_id, 'referrer', $ref_url ); // Add to order meta
}

It's great. Very useful! Thx!

He Stevenkellow,

Awesome code and very useful thanks! However, can't get it to show the page BEFORE my url is entered. As in: this code shows the page the user was before buying a product, not before entering my site. What I need is to see where the user was before he visited my site.

For example, when a visitor comes from google.com to mysite.com i want it to show google.com. Now it outputs mysite.com/cart

Any idea how to fix this?

Hmm, doesn't work for me :(

Does it work at this time?

It makes payments using Stripe impossible for me.

Does not work. Checkout page returns "Internal Server Error"
