How do I add the total weight to the packing slip?

Hi! There are two ways to do this.
If you don’t mind a little custom coding, check the instructions here. If you prefer a simpler solution, the Premium Templates extension lets you add the total weight directly in the settings via the Customizer (either in the Totals section, or with a custom block using the {{order_weight}} placeholder).

Hope that helps!

Thank you for your response. Have a placed this correctly?

I have followed the instructions, but have not been able to get the total weight to show. Please advise.

Hi! you placed the snippet inside the order details table, which breaks the layout. If you put it after the </table> tag, it should work. Here’s an update for the code so that it’s also fully compatible with PDF Invoices 2.X:

<?php
// calculate total weight & total qty
$order_weight = 0;
$order_total_qty = 0;
$items = $this->order->get_items();
if( sizeof( $items ) > 0 ) {
    foreach( $items as $item ) {
        $order_total_qty += $item['qty'];
        if ( $product = $this->order->get_product_from_item( $item ) ) {
            $order_weight += $product->get_weight() * $item['qty'];
        }
    }
}
?>

Weight: <?php echo $order_weight; ?><br/>
Quantity: <?php echo $order_total_qty; ?>

You can also use a PDF action hook instead, so that you don’t have to worry about the template getting out of date.

add_action( 'wpo_wcpdf_after_order_details', 'wpo_wcpdf_order_weight', 10, 2 );
function wpo_wcpdf_order_weight( $document_type, $order ) {
    if ($document_type == 'packing-slip') {
        // calculate total weight & total qty
        $order_weight = 0;
        $order_total_qty = 0;
        $items = $order->get_items();
        if( sizeof( $items ) > 0 ) {
            foreach( $items as $item ) {
                $order_total_qty += $item['qty'];
                if ( $product = $order->get_product_from_item( $item ) ) {
                    $order_weight += $product->get_weight() * $item['qty'];
                }
            }
        }
        ?>
        Weight: <?php echo $order_weight; ?><br/>
        Quantity: <?php echo $order_total_qty; ?>
        <?php
    }
}

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

If you need more help with this, I recommend finding a coder to help with this or getting the Premium Templates as Michael suggested. We can only offer limited support for customizations if you are using the free version.

Hope that helps!
