同时根据产品自定义字段更改WooCommerce Minicart项目价格

问题描述

基于Allow customer to set the product price (giftcard) and add to cart if sum is minimum 100 in WooCommerce，它回答了我的第一个问题-关于WooCommerce微型购物车，我还有一个小问题。

产品价格不会根据客户使用Giftcard字段提交的价格进行相应更新。因此，我有两个不同的解决方案，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'] );
        }
    }
}

不起作用：Minicart变成空白。然后我也尝试了：

add_filter('woocommerce_cart_item_price','modify_cart_product_price',3);
function modify_cart_product_price( $price,$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。

解决方法

针对各种产品的购物篮提供完整的免费价格

/**
 * Initialize Session cart
 */
add_action('init','init_cart_session',1);
function init_cart_session() {
    if (!session_id()) {
        session_start();
    }
    if (!isset($_SESSION['cart'])) {
        $_SESSION['cart'] = [];
    }
}

/**
 * Custom size correct
 */
add_action('woocommerce_before_calculate_totals','woo_size_correct',10,6);
function woo_size_correct() {
    global $woocommerce;

    if (isset($_POST['attribute_pa_size']) && $_POST['attribute_pa_size'] == 'custom') 
{
        $_SESSION['cart'][$_POST['variation_id']] = $_POST['custom'];
    }

    foreach (WC()->cart->get_cart() as $cart_item_key => $cart_item) {
        if (array_key_exists($cart_item['data']->variation_id,$_SESSION['cart'])) {
            $cart_item['data']->set_price($_SESSION['cart'][$cart_item['data']->variation_id]);
        }
    }
}
add_filter('woocommerce_cart_item_price','woo_size_mini_cart_correct',6);
function woo_size_mini_cart_correct($price_html,$cart_item,$cart_item_key) {
    global $woocommerce;

    if (array_key_exists($cart_item['data']->variation_id,$_SESSION['cart'])) {
        $args = array('price' => floatval($_SESSION['cart'][$cart_item['data']->variation_id]));

        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;
}

,

以这种方式使用的右钩子是woocommerce_cart_item_price：

add_filter( 'woocommerce_cart_item_price','giftcard_cart_item_price',3 );
function giftcard_cart_item_price( $price_html,$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，自定义价格将在微型购物车中正确显示...
