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，如果运输选项为 local_pickup，我需要删除该折扣。 我想我可以调整以下代码。它在某个地方丢失了一些东西，所以我向您寻求帮助。

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特定类别的一件或多件商品的原始价格？

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（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']);
        }
    }
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。它应该可以工作。

注意：当使用负费用（购物车折扣）时，始终会收取税款。

我挖掘了一点您的代码并进行了一些更改。感谢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' );
