我正在使用woocommerce和“打印发票和装箱单” 可在“https://woocommerce.com/products/print-invoices-packing-lists/”获得。 用于显示woocommerce购物车中的总节省量&结帐页面我使用了这段代码,效果很好:
function bbloomer_wc_discount_total() {
global $woocommerce;
$cart_subtotal = $woocommerce->cart->cart_contents;
$discount_total = 0;
foreach ($woocommerce->cart->cart_contents as $product_data) {
if ($product_data['variation_id'] > 0) {
$product = wc_get_product( $product_data['variation_id'] );
} else {
$product = wc_get_product( $product_data['product_id'] );
}
if ( !empty($product->sale_price) ) {
$discount = ($product->regular_price - $product->sale_price) * $product_data['quantity'];
$discount_total += $discount;
}
}
if ( $discount_total > 0 ) {
echo '<tr class="cart-discount">
<th>'. __( 'Total Saving :', 'woocommerce' ) .'</th>
<td data-title=" '. __( 'Total Saving :', 'woocommerce' ) .' ">'
. wc_price($discount_total+$woocommerce->cart->discount_cart) .'</td>
</tr>';
}
}
add_action( 'woocommerce_cart_totals_after_order_total', 'bbloomer_wc_discount_total');
add_action( 'woocommerce_review_order_after_order_total', 'bbloomer_wc_discount_total');
此功能基于woocommerce购物车内容。 如何显示由打印发票生成的Html发票中的总节省量&amp;装箱单插件(基于订单而不是购物车内容)插件中的挂钩如:
add_action('wc_pip_after_header','bbloomer_wc_discount_total'); add_action('wc_pip_document_header','bbloomer_wc_discount_total');
答案 0 :(得分:2)
- 更新2 - (添加了WooCommerce版本3 +的兼容性)
现在我知道你正在使用 WooCommerce PDF发票&amp;装箱单插件。
此代码只能在开头的 invoice.php
PIP模板中直接使用,由此替换 <?php global $wpo_wcpdf ?>
:
<?php
global $wpo_wcpdf, $woocommerce;
// Get the order object
$_order = $wpo_wcpdf->export->order;
foreach ( $_order->get_items() as $item ) {
// Added WC 3+ compatibility
$quantity = method_exists( $item, 'get_quantity' ) ? $item->get_quantity() : $item['quantity'];
$variation_id = method_exists( $item, 'get_variation_id' ) ? $item->get_variation_id() : $item['variation_id'];
$_product = version_compare( WC_VERSION, '3.0', '<' ) ? wc_get_product( $item['product_id'] ) : $item->get_product();
// Get the product object when it's a product variation ( Before version WC 3+)
if ( version_compare( WC_VERSION, '3.0', '<' ) )
if ($item['variation_id'] > 0) $_product = wc_get_product( $item['variation_id'] );
// Get prices
$sale_price = $_product->get_sale_price();
$regular_price = $_product->get_regular_price();
// Only when sale price exits
if ( ! empty( $sale_price ) && $sale_price > 0 ) {
$discount = ($regular_price - $sale_price) * $item->get_quantity();
$discount_total += $discount;
}
}
if ( $discount_total > 0 ) {
$display_discount = '<tr class="cart-discount">
<th>'. __( 'Total you saved :', 'woocommerce' ) .'</th>
<td data-title=" '. __( 'Total you saved :', 'woocommerce' ) .' ">' . wc_price( $discount_total + $_order->get_total_discount() ) .'</td>
</tr>';
}
?>
然后你可以在模板输出的地方使用它,这样(在html里面):
<?php echo $display_discount; ?>
或(在PHP代码中):
echo $display_discount;
此代码经过测试并有效。
