在Woocommerce购物车小部件中显示购物车项目数

提问于

我试图在Woocommerce购物车小部件的底部或顶部显示购物车中的商品数量 . 似乎默认情况下,购物车小部件在侧边栏中不会执行此操作 .

我已经研究过SO并发现了以下answer,但它的目标略有不同,即添加单个小计 . 我尝试修改它,通过传入 WC()->cart->get_cart_contents_count() 而不是 WC()->cart->get_cart() 来查看我是否可以获得购物车项目计数,但它没有显示...任何建议?

Example of what I am trying to do:

Code I have modified from the approved answer:

<?php
/**
 * Mini-cart
 *
 * Contains the markup for the mini-cart, used by the cart widget
 *
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.1.0
 */

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
?>

<?php do_action( 'woocommerce_before_mini_cart' ); ?>

<ul class="cart_list product_list_widget <?php echo $args['list_class']; ?>">

    <?php if ( WC()->cart->get_cart_contents_count() ) > 0 ) : ?>

        <?php
            foreach ( WC()->cart->get_cart_contents_count() as $cart_item_key => $cart_item ) {
                $_product     = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
                $product_id   = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );

                if ( $_product && $_product->exists() && $cart_item['quantity'] > 0 && apply_filters( 'woocommerce_widget_cart_item_visible', true, $cart_item, $cart_item_key ) ) {

                    $product_name  = apply_filters( 'woocommerce_cart_item_name', $_product->get_title(), $cart_item, $cart_item_key );

    如果要在迷你购物车小部件中显示购物车项目计数,可以使用挂钩:

    1)在minicart内容之前的顶部:

    add_action( 'woocommerce_before_mini_cart', 'minicart_count_after_content' );
    function minicart_count_after_content() {
        $items_count = WC()->cart->get_cart_contents_count();
        $text_label  = _n( 'Item', 'Items', $items_count, 'woocommerce' );
        ?>
            <p class="total item-count"><strong><?php echo $text_label; ?>:</strong> <?php echo $items_count; ?></p>
        <?php
    }
    

    2)按钮前面的底部:

    add_action( 'woocommerce_widget_shopping_cart_before_buttons', 'minicart_count_before_content' );
    function minicart_count_before_content() {
        $items_count = WC()->cart->get_cart_contents_count();
        $text_label  = _n( 'Item', 'Items', $items_count, 'woocommerce' );
        ?>
            <p class="total item-count"><strong><?php echo $text_label; ?>:</strong> <?php echo $items_count; ?></p>
        <?php
    }
    

    代码位于活动子主题(或活动主题)的function.php文件中 . 经过测试和工作 .


    WC()->cart->get_cart_contents_count(); 将为您提供包括数量在内的总物品数量 .

    如果你想在购物车中获得 the number of items ,你将使用:

    $items_count = sizeof( WC()->cart->get_cart() );

    你没有在任何地方回显WC() - > cart-> get_cart_contents_count(),所以不,它不会显示 .

    无论在代码中您需要显示计数,您都需要使用

    echo WC()->cart->get_cart_contents_count();
