Question

我正在生成我的购物车：

if( !is_wp_error( $this->getCartContentsCount() ) ) {
    $cart_items = WC()->cart->get_cart();
    foreach( $cart_items as $item ) { ?>
        <div class="left col-md-3">
            <div class="product-image"><!-- Make sure ot check if it's a gallery, if so, get its first image -->
                <?php echo $item['data']->get_image(); ?>
            </div>
        </div>
        <div class="right col-md-8">
            <h4 class="product-name"><?php echo $item['data']->get_name(); ?></h4>
            <div class="product-information">
                <span class="product-quantity"><?php echo $item['quantity'] . 'x' ?></span>
                <span class="product-price"><?php echo $item['data']->get_price_html(); ?></span>
            </div>
            <?php
                echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf(
                    '<a href="%s" aria-label="%s" data-product_id="%s" data-product_sku="%s">X</a>',
                    esc_url( wc_get_cart_remove_url( $item ) ),
                    __( 'Remove this item', 'woocommerce' ),
                    esc_attr( $item['product_id'] ),
                    esc_attr( $item['data']->get_sku() )
                ), $item );
            ?>
            </div>
    <?php }
}

正如您所看到的，我正在按照cart.php使用“删除项目”机制的基本Woocommerce实现，但不幸的是，它不起作用。

这就是Woo生成的内容：

<a href="http://127.0.0.1/wordpress/cart/?remove_item%5Bkey%5D=6e7b33fdea3adc80ebd648fffb665bb8&amp;remove_item%5Bproduct_id%5D=807&amp;remove_item%5Bvariation_id%5D=0&amp;remove_item%5Bquantity%5D=1&amp;remove_item%5Bline_subtotal%5D=40&amp;remove_item%5Bline_subtotal_tax%5D=0&amp;remove_item%5Bline_total%5D=40&amp;remove_item%5Bline_tax%5D=0&amp;remove_item%5Bdata%5D&amp;_wpnonce=2242057dec" aria-label="Remove this item" data-product_id="807" data-product_sku="235677r">X</a>

我检查了每个属性，确实有效！

其他症状：

如果直接访问该链接，会将我带到购物车本身（我相信这是由于nonce）。
在点击之前和之后倾倒购物车仍然显示相同的内容只有一个项目的购物车，所以删除机制没有因为购物车不会改变其状态。

怎么会不起作用？

我实际上已经开始复制cart.php实施并根据我的需要进行定制：

ob_start();

if( !is_wp_error( $this->getCartContentsCount() ) ) { //This checks if there are any items in the cart.
    foreach( WC()->cart->get_cart() 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_cart_item_visible', true, $cart_item, $cart_item_key ) ) {
            $product_permalink = apply_filters(
                'woocommerce_cart_item_permalink',
                $_product->is_visible() ? $_product->get_permalink( $cart_item ) : '', $cart_item, $cart_item_key
            ); ?>

            <div class="cart-item <?php echo esc_attr( apply_filters( 'woocommerce_cart_item_class', 'cart_item', $cart_item, $cart_item_key ) ); ?>">

                            $_product->get_image(), $cart_item, $cart_item_key

                        if ( !$product_permalink ) {

ob_end_clean();

echo $markup_output;

Answer 2

简单使用此WC_Cart::remove_cart_item( $cart_item_key );

如何在WooCommerce中从购物车中删除我的商品？
