php-在Woocommerce购物车小部件中显示购物车项目计数

我试图在Woocommerce购物车小部件的底部或顶部显示购物车中物品的数量.似乎默认情况下,在侧栏中时,购物车小部件不会执行此操作.

我研究了SO,发现了以下answer,但添加单个小计的目标略有不同.我尝试通过传递WC()-> cart-> get_cart_contents_count()而不是WC()-> cart-> get_cart()来进行修改,以查看是否可以获取购物车商品计数,但是没有显示…任何建议？

我尝试做的例子：

我从批准的答案中修改了代码：

<?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 );
                    $thumbnail     = apply_filters( 'woocommerce_cart_item_thumbnail', $_product->get_image(), $cart_item, $cart_item_key );
                    $product_price = apply_filters( 'woocommerce_cart_item_price', WC()->cart->get_product_price( $_product ), $cart_item, $cart_item_key );
                    echo "<p>".$product_price."</p>";
                    ?>
                    <li>
                    <?PHP if ( ! $_product->is_visible() ) { ?>
                        <?PHP echo str_replace( array( 'http:', 'https:' ), '', $thumbnail ) . $product_name; ?>
                    <?PHP } else { ?>
                        <a href="<?PHP echo get_permalink( $product_id ); ?>">
                            <?PHP echo str_replace( array( 'http:', 'https:' ), '', $thumbnail ) . $product_name; ?>
                        </a>
                    <?PHP } ?>
                        <?PHP echo WC()->cart->get_item_data( $cart_item ); ?>
                        <?PHP   $new_product_price_array = explode ( get_woocommerce_currency_symbol(), $product_price); 
                                $new_product_price = number_format((float)$new_product_price_array[1] * $cart_item['quantity'], 2, '.', '');

                        ?>
                        <?PHP echo apply_filters( 'woocommerce_widget_cart_item_quantity', '<span class="quantity">' . sprintf( '%s &times; %s=%s%s', $cart_item['quantity'], $product_price,get_woocommerce_currency_symbol(), $new_product_price ) . '</span>', $cart_item, $cart_item_key ); ?>
                    </li>
                    <?PHP
                }
            }
        ?>

    <?PHP else : ?>

        <li class="empty"><?PHP _e( 'No products in the cart.', 'woocommerce' ); ?></li>

    <?PHP endif; ?>

</ul><!-- end product list -->

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

    <p class="total"><strong><?PHP _e( 'Subtotal', 'woocommerce' ); ?>:</strong> <?PHP echo WC()->cart->get_cart_subtotal(); ?></p>

    <?PHP do_action( 'woocommerce_widget_shopping_cart_before_buttons' ); ?>

    <p class="buttons">
        <a href="<?PHP echo WC()->cart->get_cart_url(); ?>" class="button wc-forward"><?PHP _e( 'View Cart', 'woocommerce' ); ?></a>
        <a href="<?PHP echo WC()->cart->get_checkout_url(); ?>" class="button checkout wc-forward"><?PHP _e( 'Checkout', 'woocommerce' ); ?></a>
    </p>

<?PHP endif; ?>

<?PHP do_action( 'woocommerce_after_mini_cart' ); ?>

解决方法:

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)在微型车内容之前：

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)在按钮下方的底部：

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
}

代码进入您的活动子主题(或活动主题)的function.PHP文件中.经过测试和工作.

WC() – &GT cart-&GT get_cart_contents_count();将为您提供总项目数,包括数量.

如果要获取购物车中的物品数,请改用：

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