在Woocommerce购物车小部件中显示购物车项目数

标签: php wordpress woocommerce cart hook-woocommerce

我正在尝试在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。

我研究了SO并找到了以下answer,但它的目标略有不同,即添加单个小计。我尝试通过传递WC()->cart->get_cart_contents_count() 而不是 WC()->cart->get_cart()来修改它,看看我是否可以获得购物车项目计数,但它没有显示...有什么建议吗?

我正在尝试做的示例:

代码我已从批准的答案进行了修改:

<?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 );

                    $product_price = apply_filters( 'woocommerce_cart_item_price', WC()->cart->get_product_price( $_product ), $cart_item, $cart_item_key );
                    echo "<p>".$product_price."</p>";
                    ?>

如果要在迷你购物车小部件中显示购物车项目数量,可以使用挂钩:

1)在minicart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
}

代码放在活动子主题(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项数。

如果您想在购物车中获得商品数量,请改用:

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

你没有在任何地方回应WC() - &gt; cart-&gt; get_cart_contents_count(),所以不,它不会显示。

在代码中,只要您需要显示计数,就需要使用

override func tableView(_ tableView: UITableView, titleForFooterInSection section: Int) -> String? {
    return NSLocalizedString("This is some random text.", comment: "") + NSLocalizedString("Refresh", comment: "")
}

override func tableView(_ tableView: UITableView, willDisplayFooterView view: UIView, forSection section: Int) {

    guard let label = view.subviews[1].subviews.first as? UILabel else {
        return
    }
    let text = label.text!
    let underlineAttriString = NSMutableAttributedString(string: text)
    let range = (text as NSString).range(of: NSLocalizedString("Refresh", comment: ""))
    underlineAttriString.addAttribute(.foregroundColor, value: UIColor.blue, range: range)
    label.attributedText = underlineAttriString
    view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(refreshTapped)))
}
