在Woocommerce中恢复特定运输方式的折扣产品价格

Question

我正在尝试找到以下问题的解决方案。 我一直在使用Woocommerce动态定价，以便为特定产品类别应用25%的折扣。 然后，如果local_pickup运输选项，我需要删除该折扣。 我想我可以调整以下代码。它在某处缺少一些东西，所以我向你寻求帮助。

function discount_table(){
// Set $cat_in_cart to false
$cat_in_cart = false;
// Loop through all products in the Cart        
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
if ( has_term( 'category_1', 'product_cat', $cart_item['product_id'] ) ) {
$cat_in_cart = true;
break;
}
}
$total = WC()->cart->subtotal;
$sconto_label = "";
if($total >= 300){
$sconto_label=15;       
}elseif($total >= 220){
$sconto_label=10;
}elseif($total >= 150){
$sconto_label=8;
}elseif($total >= 100){
$sconto_label=4;
}
$chosen_methods = WC()->session->get( 'chosen_shipping_methods' );
$chosen_shipping = explode(':',$chosen_methods[0]);
if($chosen_shipping[0]=='local_pickup' && !$cat_in_cart){
$sconto_label=25;
}
else if ($chosen_shipping[0]=='local_pickup' && $cat_in_cart){
$sconto_label=25;
// there should be something here or not?
}
$sconto_cliente = (($total*$sconto_label)/100);
if($sconto_label!="")
$sconto_cliente_net = ($sconto_loison/1.1);
WC()->cart->add_fee( "Discount ($sconto_label%)", -$sconto_cliente_net, false );
}
add_action( 'woocommerce_cart_calculate_fees','discount_table' );

有没有办法恢复购物车中已经打折的一件或多件特定类别商品的原价？

要根据产品类别和特定选择的运输方式恢复购物车商品价格，请尝试以下操作(对于Woocommerce动态定价(：

add_filter('woocommerce_add_cart_item_data', 'add_default_price_as_cart_item_custom_data', 50, 3 );
function add_default_price_as_cart_item_custom_data( $cart_item_data, $product_id, $variation_id ){
// HERE define your product category(ies)
$categories = array('t-shirts');
if ( has_term( $categories, 'product_cat', $product_id ) ) {
$product_id = $variation_id > 0 ? $variation_id : $product_id;
// The WC_Product Object
$product = wc_get_product($product_id);
// Get product default base price
$price = (float) $product->get_price();
// Set the Product default base price as custom cart item data
$cart_item_data['default_price'] = $price;
}
return $cart_item_data;
}
add_action( 'woocommerce_before_calculate_totals', 'restore_cart_item_price', 900, 1 );
function restore_cart_item_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// HERE set the targeted Chosen Shipping method
$targeted_shipping_method = 'local_pickup';
// Get the chosen shipping method
$chosen_methods            = WC()->session->get( 'chosen_shipping_methods' );
$chosen_shipping_method_id = explode(':', reset($chosen_methods) );
$chosen_shipping_method    = reset($chosen_shipping_method_id);
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ) {
if( $targeted_shipping_method == $chosen_shipping_method && isset($cart_item['default_price']) ){
// Set back the default cart item price
$cart_item['data']->set_price($cart_item['default_price']);
}
}
}

代码进入函数.php活动子主题(或活动主题(的文件。它应该有效。

注意：使用负费用(购物车折扣(时，始终收取税费。

我挖掘了一点你的代码并进行了一些更改。多亏了超级开发人员，发现了一个错误！代码如下：

function discount_table(){
$cat_in_cart = false;
$tot_cat = 0;
foreach ( WC()->cart->get_cart() as $cart_item ) {
if ( has_term( 'cat1', 'product_cat', $cart_item['product_id'] ) ) {
$cat_in_cart = true;
$tot_cat_price = $cart_item['data']->get_price();
$tot_cat_qty = $cart_item['quantity'];
$tot_cat +=  $tot_cat_price * $tot_cat_qty;
//break;
/* commented here, thanks to Michael Ramin: break will stop execution of the loop after found the first product belonging to the category; what if you have more than one? so remove break instruction */
}
}
global $product;
$total = WC()->cart->subtotal;
$discount_label = "";
if($total >= 300){
$discount_label=15;     
}elseif($total >= 220){
$discount_label=10;
}elseif($total >= 150){
$discount_label=8;
}elseif($total >= 100){
$discount_label=4;
}
$chosen_methods = WC()->session->get( 'chosen_shipping_methods' );
$chosen_shipping = explode(':',$chosen_methods[0]);
if($chosen_shipping[0]=='local_pickup'){
$discount_label=25;
}
$discount_brand = ($total-$tot_cat)*$discount_label/100;
if($discount_label!=""){
$discount_brand_net = ($discount_brand/1.1);
if($discount_brand_net != 0) // show discount only if != 0; it may happen if cart includes only targeted category products;
WC()->cart->add_fee( "Discount ($discount_label%)", -$discount_brand_net, false );
}   
}
add_action( 'woocommerce_cart_calculate_fees','discount_table' );
