WooCommerce: Save & Display Order Total Weight

For tracking purposes, or maybe because your shop manager needs to be aware of this, saving the total weight of each order and displaying it on the single order admin page is quite simple.

That’s right – WooCommerce does not save this value by default. You either need to save it yourself into the “order meta” or recalculate the weight based on the order items and their quantities. Here, we’ll cover option one (saving is better than calculating in regard to performance).

    $weight = WC()->cart->get_cart_contents_weight();
    update_post_meta( $order_id, '_cart_weight', $weight );
}

add_action( 'woocommerce_admin_order_data_after_billing_address', 'bbloomer_delivery_weight_display_admin_order_meta', 10, 1 );
 
function bbloomer_delivery_weight_display_admin_order_meta( $order ) {    
    echo '<p><strong>Order Weight:</strong> ' . get_post_meta( $order->get_id(), '_cart_weight', true ) . get_option( 'woocommerce_weight_unit' ) . '</p>';
}

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.

  1. Ohhh I forgot the php tags ๐Ÿ™‚ And I can’t edit — Sorry!

    1. Added them for you ๐Ÿ™‚ Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  2. Hi Rodolfo,

    Thanks for this…
    I already have 2 of them in my functions.php ๐Ÿ™‚ One to show on the “orders overview” page and one inside the order and print it on the order email – that is on my table when I am doing / packing and printing the Shipment label

    Any chance it can be combined into one – to rule them all?

    Here is the two snippets

    /**
    * Here is that custom function that will show on "Order page overview" the total weight pr. order
    * gist.github.com/kloon/5299119
    */
    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-&gt;id != $post-&gt;ID )
    		$the_order = new WC_Order( $post-&gt;ID );
    	if ( $column == 'total_weight' ) {
    		$weight = 0;
    		if ( sizeof( $the_order-&gt;get_items() ) &gt; 0 ) {
    			foreach( $the_order-&gt;get_items() as $item ) {
    				if ( $item['product_id'] &gt; 0 ) {
    					$_product = $the_order-&gt;get_product_from_item( $item );
    					if ( ! $_product-&gt;is_virtual() ) {
    						$weight += $_product-&gt;get_weight() * $item['qty'];
    					}
    				}
    			}
    		}
    		if ( $weight &gt; 0 )
    			print $weight . ' ' . esc_attr( get_option('woocommerce_weight_unit' ) );
    		else print 'N/A';
    	}
    }
    
    1. And the second Snippet (If I add yours to the buttom of this … The site crashes? ๐Ÿ™

      /**
      * Here is that custom function hooked in woocommerce_email_after_order_table action hook, that will show on "New order" email notification the total weight
      * stackoverflow.com/questions/45701473/add-the-order-total-weight-to-woocommerce-new-order-email-notification
      */
      add_action('woocommerce_email_after_order_table','show_total_weight', 10, 4);
      function show_total_weight( $order, $sent_to_admin, $plain_text, $email ){
      
          if ( 'new_order' != $email-&gt;id ) return;
      
          $total_weight = 0;
      
          foreach( $order-&gt;get_items() as $item_id =&gt; $product_item ){
              $quantity = $product_item-&gt;get_quantity(); // get quantity
              $product = $product_item-&gt;get_product(); // get the WC_Product object
              $product_weight = $product-&gt;get_weight(); // get the product weight
              // Add the line item weight to the total weight calculation
              $total_weight += floatval( $product_weight * $quantity );
          }
      
          // Styles
          $style1 = 'style="width: 100%; font-family: \'Helvetica Neue\', Helvetica, Roboto, Arial, sans-serif; color: #737373; border: 1px solid #e4e4e4; border-top:0;"';
          $style2 = 'style="text-align: left; border-top-width: 4px; color: #737373; border: 1px solid #e4e4e4; padding: 12px;border-top:0;"';
          $style3 = 'style="text-align: left; border-top-width: 4px; color: #737373; border: 1px solid #e4e4e4; padding: 12px;border-top:0;"';
      
          // Output
          echo "" . __( 'Total Product Weight: ', 'woocommerce' ) . "" . $total_weight . " kg.";
      }
      
  3. Do you think this would be better transferred to the order details and to the print order or packing list.

    If for example, the shipping does not have access to the woocommerce backend.

    1. Hey Roberta, yes, you can display it wherever you like – just change hook ๐Ÿ™‚
