Sku Order

Hello Kelly,
That is certainly possible. ??
With the following filter you can sort your items by SKU:

//Sort items by SKU
add_filter( 'wpo_wcpdf_order_items_data', 'wpo_wcpdf_sort_items_by_sku', 10, 2 );
function wpo_wcpdf_sort_items_by_sku ( $items, $order ) {
	usort($items, 'wpo_wcpdf_sort_by_sku');
	return $items;
}

function wpo_wcpdf_sort_by_sku($a, $b) {
	if ($a['sku']==$b['sku']) return 0;
	return ($a['sku']<$b['sku'])?-1:1;
}

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

Have a great day & let us know if you need more help with this!
