WooCommerce: Remaining Stock @ Order Emails

This is a neat customization, directly requested by a WooWeekly subscriber who needed to literally show the remaining stock quantity for each ordered item to store managers, in order to have an immediate idea of low/zero stock quantities after each order.

If that’s not clear, simply take a look at the screenshot. In my dev site, I ordered a product that originally had stock quantity = 1. In the “New Order” email (thanks to the snippet below), beside the order item quantity of 1, there is also a “(0 remaining)” notice that clearly displays the item’s current stock level.

Cool, ha? So, let’s see how that’s coded. Enjoy!

PHP Snippet: Display Remaining Item Stock Quantity @ New Order WooCommerce Emails

Note: the snippet requires we add the “email ID” to the $GLOBALS first. This is because we want to target only the “new_order” emails. This workaround is needed because the following filter, “woocommerce_email_order_item_quantity“, does not give us access to the email ID unfortunately.

If you want to show this on ALL emails, you can avoid that first step, and also remove the email ID check in the second step.

// ----------
// STEP 1: DECLARE EMAIL ID GLOBAL

add_action( 'woocommerce_email_before_order_table', 'bbloomer_email_id_as_global', 9999, 4 );

function bbloomer_email_id_as_global( $order, $sent_to_admin, $plain_text, $email ){
    $GLOBALS['email_id'] = $email->id;
}

// ----------
// STEP 2: IF NEW ORDER EMAIL, ADD REMAINING STOCK QUANTITY

add_filter( 'woocommerce_email_order_item_quantity', 'bbloomer_item_remaining_stock', 9999, 2 );

function bbloomer_item_remaining_stock( $qty_display, $item ) {
	 $email_id = $GLOBALS['email_id'];
    if ( empty( $email_id ) ) return $qty_display;
    if ( 'new_order' !== $email_id ) return $qty_display;
	 $product = $item->get_product();
	 if ( is_object( $product ) && $product->managing_stock() ) {
		 $qty_display .= ' (' . $product->get_stock_quantity() . ' remaining)';
	 }
	 return $qty_display;
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
