Use the below code snippet to display the SKU next to the item name when the order is scheduled inside Google Calendar:
function sl_cc_chwazi_gcalendar_alter_order_items($replacements, $order){
$order_items = $order->get_items();
$order_items_array = array();
foreach ( $order_items as $item_id => $item ) {
$product = $item->get_product();
$sku = $product ? "(" . $product->get_sku() . ")" : '';
$order_items_array[] = $item->get_name() . " $sku x " . $item->get_quantity();
}
$replacements['{order_items}'] = implode( "\n", $order_items_array );
return $replacements;
}
add_filter('chwazi_gcalendar_event_replacement_tags', 'sl_cc_chwazi_gcalendar_alter_order_items', 10, 2);
