还可以根据产品自定义字段更改 WooCommerce Minicart 商品价格

Question

基于允许客户设置产品价格（礼品卡）并在 WooCommerce 中金额至少为 100 时添加到购物车，这回答了我的最初问题 - 我剩下一个关于 WooCommerce 迷你车的小问题。产品价格不会根据客户使用礼品卡字段提交的价格进行更新。所以我有两种不同的解决方案，但都失败了。这是我尝试过的：add_filter('woocommerce_widget_cart_item_quantity', 'custom_wc_widget_cart_item_quantity', 10, 3 );function custom_wc_widget_cart_item_quantity( $cart, $cart_item, $cart_item_key ) {    foreach ( $cart->get_cart() as $cart_item ) {        if ( isset ( $cart_item['giftcard_product_price'] ) ) {        $cart_item['data']->set_price( $cart_item['giftcard_product_price'] );        return sprintf( '<span class="quantity">%s &times; <span class="woocommerce-Price-amount amount">%s <span class="woocommerce-Price-currencySymbol">%s</span></span></span>', $cart_item['quantity'], $cart_item['giftcard_product_price'] );        }    }}它不起作用：小车一片空白。然后我也尝试过：add_filter('woocommerce_cart_item_price','modify_cart_product_price',10,3);function modify_cart_product_price( $price, $cart_item, $cart_item_key){    $price = $cart_item['data']->set_price($cart_item['giftcard_product_price']);    return $price;}我能得到的任何帮助将不胜感激。

Answer 1

使用的正确钩子是woocommerce_cart_item_price这样的：

add_filter( 'woocommerce_cart_item_price', 'giftcard_cart_item_price', 10, 3 );

function giftcard_cart_item_price( $price_html, $cart_item, $cart_item_key ) {

    $giftcard_key = 'giftcard_product_price';

    if( isset( $cart_item[$giftcard_key] ) ) {

        $args = array( 'price' => floatval( $cart_item[$giftcard_key] ) );

        if ( WC()->cart->display_prices_including_tax() ) {

            $product_price = wc_get_price_including_tax( $cart_item['data'], $args );

        } else {

            $product_price = wc_get_price_excluding_tax( $cart_item['data'], $args );

        }

        return wc_price( $product_price );

    }

    return $price_html;

}

现在自定义价格将正确显示在迷你车中......
