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 );
$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 × %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' ); ?>

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:
2)按钮前面的底部:
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:
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
