您的实际代码只是删除所有总计,仅显示小计。请尝试以下钩子函数,该函数将在折扣金额后显示折扣小计:
add_filter( 'wpo_wcpdf_woocommerce_totals', 'add_discounted_subtotal_to_pdf_invoices', 10, 2 );
function add_discounted_subtotal_to_pdf_invoices( $totals, $order ) {
// Get 'subtotal' raw amount value
$subtotal = strip_tags($totals['cart_subtotal']['value']);
$subtotal = (float) preg_replace('/[^0-9.]+/', '', $subtotal);
// Get 'discount' raw amount value
$discount = strip_tags($totals['discount']['value']);
$discount = (float) preg_replace('/[^0-9.]+/', '', $discount);
$new_totals = array();
// Loop through totals lines
foreach( $totals as $key => $values ){
$new_totals[$key] = $totals[$key];
// Inset new calculated 'Subtotal discounted' after total discount
if( $key == 'discount' && $discount != 0 && !empty($discount) ){
$new_totals['subtotal_discounted'] = array(
'label' => __('Subtotal discounted', 'wpo_wcpdf'),
'value' => wc_price($subtotal - $discount)
);
}
}
return $new_totals;
}
代码进入活动子主题(或主题)的 function.php 文件中。
测试和工作。它也应该对你有用。
