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.
