Amelia Booking Details in PDF Invoice

For those people wanting to ensure that booking details from the Amelie Booking plugin appear in PDF invoices, just add this code to your theme’s functions.php file:

//
// ADD AMELIA BOOKING DETAILS TO PDF INVOICE
// 

add_action( 'wpo_wcpdf_after_item_meta', function( $document_type, $item, $order ) {
    if ($document_type == 'invoice') {
        if ( $extra_option = wc_get_order_item_meta( $item['item_id'], 'ameliabooking', true ) ) {
            $extra_option_array = maybe_unserialize( $extra_option );
    
            if ( is_array( $extra_option_array ) && isset( $extra_option_array['labels'] ) ) {
                $labels = $extra_option_array['labels'];
                echo '<div class="booking-details">' . $labels . '</div>';
            } else {
                echo 'Invalid or missing booking details.';
            }
        }
    }
}, 10, 3 );
