WooCommerce total order weight column on orders page

functions.php

<?php
add_filter( 'manage_edit-shop_order_columns', 'woo_order_weight_column' );
function woo_order_weight_column( $columns ) {
  $columns['total_weight'] = __( 'Weight', 'woocommerce' );
	return $columns;
}

add_action( 'manage_shop_order_posts_custom_column', 'woo_custom_order_weight_column', 2 );
function woo_custom_order_weight_column( $column ) {
	global $post, $woocommerce, $the_order;

	if ( empty( $the_order ) || $the_order->get_id() !== $post->ID )
		$the_order = new WC_Order( $post->ID );

	if ( $column == 'total_weight' ) {
		$weight = 0;
		if ( sizeof( $the_order->get_items() ) > 0 ) {
			foreach( $the_order->get_items() as $item ) {
				if ( $item['product_id'] > 0 ) {
					$_product = $item->get_product();
					if ( ! $_product->is_virtual() ) {
						$weight += $_product->get_weight() * $item['qty'];
					}
				}
			}
		}
		if ( $weight > 0 ) {
			print $weight . ' ' . esc_attr( get_option('woocommerce_weight_unit' ) );
		} else {
			print 'N/A';
		}
	}
}
?>

Which file does this go in to display total weights?

If the code doesn't work first time, just add a later priority to the main filter to avoid that WC clears columns while loading :

add_filter( 'manage_edit-shop_order_columns', 'woo_order_weight_column',20 );

Awesome. It works like a charm! Thank you.

I am trying to pull the order weight using a UPS Worldship Export Plugin (myzoogu.com)

How can I modify the following code to pull weight as well? I was able to get the order column, but it would be great to some how store it in meta data.

$query = $wpdb->prepare( "SELECT orden.ID AS order_number,
                    orden.post_modified AS last_date,
                    orden.post_excerpt AS deliverynotes,
                    orden.post_modified AS formatteddate,
                    user.ID AS user_id,
                    user.user_email AS user_email,
                    user.display_name AS user_name,
                    user.user_login AS user_login
                    FROM {$wpdb->posts} AS orden
                    LEFT JOIN {$wpdb->postmeta} AS meta
                    ON (meta.post_id = orden.ID)
                    LEFT JOIN {$wpdb->users} AS user
                    ON (user.ID=meta.meta_value )
                    WHERE
                    orden.post_type='shop_order'
                    AND orden.post_status not in ('trash',  'auto-draft')
                    AND meta.meta_key='_customer_user'
                    AND orden.ID IN ({$orderIdsArrStr})" , '');

                $results = $wpdb->get_results($query);

                if ( !empty( $results ) ) {
                    $OrderXML = '<?xml version="1.0"?>
                <OpenShipments xmlns="x-schema:OpenShipments.xdr">';

                    foreach($results as $result) {

                        $OrderId=$result->order_number;
                        $user_email=$result->user_email;
                        $user_id=$result->user_id;
                       $NewOrderID=get_post_meta( $OrderId, "_order_number", true );

Any chance this could be updated?
Maybe even combined with this: https://stackoverflow.com/questions/45701473/add-the-order-total-weight-to-woocommerce-new-order-email-notification
And to make it complete - For the customers too?: like this: https://da.wordpress.org/plugins/woo-order-weight/
One plugin to rule them all :-)

Lines 10-14 saved me! Thanks @kloon!

You sir are awesome! :)

is there anyway this can be added to the Order page? ( the page with all the details on it)
Seems it is only on the Orders list)

I got this in error log today:
"PHP Deprecated: WC_Abstract_Legacy_Order :: get_product_from_item
Use $item->get_product() instead."

fix:
replace L20
$_product = $the_order->get_product_from_item( $item );
by
$_product = $item->get_product();

However, now I get:
PHP Notice: id was called incorrectly. Order properties should not be accessed directly.

How to fix this?

I updated the gist to make it compatible with the latest version of WooCommerce.

I have changed line 22 to avoid PHP Warning: A non-numeric value encountered

$weight += floatval($_product->get_weight()) * $item['quantity'];

Fantastic, worked flawlessly!

Awesome Brother works like a charm!

Hi, works fine thank you!
do you have any idea how to get an total order weight on each order in a customers my account? i searching desperatly 2 days to find a sollution for this, your code works for the admin, but want almost the same for customers

Hi! I need to show the total weight of the order in the Frontend @ the Order of My Account. I have found the way to add the columns and show some product data but not the weight. Help will be much appreciated!

Is there a way to store this value in an Advanced Custom Field or as order meta field?

The code is now giving:
Warning: A non-numeric value encountered in /home/public_html/wp-content/plugins/theme-customisations/custom/functions.php on line xx
Where xx=$weight += $_product->get_weight() * $item['qty'];
I fixed it by using the is_numeric on $product_weight before using it.

Hi Lads,
You are all awesome - Can one of you please post the entire script now with all the new stuff so it's error free and PHP 8.2 freindly

Would it be possible to get an updated version of this code? I would like to run it will php 8.1 and above if possible please.
