按 SKU 对购物车 WooCommerce 中产品列表底部的产品进行排序

Question

在 WooCommerce 中，我使用一个代码来显示牛排重量选择表单，保存选择数据并在购物车、结帐页面、编辑订单时和电子邮件通知中显示这些数据。我的代码还结合了一个代码，在将任何产品添加到购物车时自动添加包装。添加包装发生在 SKU 上。有一次，用户@7uc1f3r 帮助进行了自定义排序，使包装始终位于购物车中产品列表的最底部。function sort_cart_specific_product_at_bottom( $cart ) {        // Product id's to to display at tbe bottom of the product list    $product_ids_last = array( 30, 815 );    // Set empty arrays    $products_in_cart = array();    $products_last = array();    $cart_contents = array();    // Loop through cart items    foreach ( $cart->get_cart() as $cart_item_key => $cart_item ) {        // Get product id        $product_id = $cart_item['data']->get_id();        // In_array — checks if a value exists in an array        if ( in_array( $product_id, $product_ids_last) ) {            // Add to products last array            $products_last[ $cart_item_key ] = $product_id;        } else {            // Add to products in cart array            $products_in_cart[ $cart_item_key ] = $product_id;        }    }    // Merges the elements together so that the values of one are appended to the end of the previous one.    $products_in_cart = array_merge( $products_in_cart, $products_last );    // Assign sorted items to cart    foreach ( $products_in_cart as $cart_item_key => $product_id ) {        $cart_contents[ $cart_item_key ] = $cart->cart_contents[ $cart_item_key ];    }    // Cart contents    $cart->cart_contents = $cart_contents;}add_action( 'woocommerce_cart_loaded_from_session', 'sort_cart_specific_product_at_bottom', 10, 1 );但不幸的是，排序代码有点过时，因为现在包裹是按SKU添加的，而不是按ID添加的。因此，排序不起作用。考虑到按 SKU 添加包装，如何更改排序代码？我很乐意为您提供帮助！

以下代码将根据产品 sku 对产品进行最后排序

function sort_cart_specific_product_at_bottom( $cart ) { 

    // Product sku to to display at tbe bottom of the product list

    $product_sku_last = array( 'lunchbox', 'pakket' );

    // Set empty arrays

    $products_in_cart = array();

    $products_last = array();

    $cart_contents = array();

    // Loop through cart items

    foreach ( $cart->get_cart() as $cart_item_key => $cart_item ) {

        // Get product sku

        $product_sku = $cart_item['data']->get_sku();

        // Get product id

        $product_id = $cart_item['data']->get_id();

        // In_array — checks if a value exists in an array

        if ( in_array( $product_sku, $product_sku_last ) ) {

            // Add to products last array

            $products_last[ $cart_item_key ] = $product_id;

        } else {

            // Add to products in cart array

            $products_in_cart[ $cart_item_key ] = $product_id;

        }

    }

    // Merges the elements together so that the values of one are appended to the end of the previous one.

    $products_in_cart = array_merge( $products_in_cart, $products_last );

    // Assign sorted items to cart

    foreach ( $products_in_cart as $cart_item_key => $product_id ) {

        $cart_contents[ $cart_item_key ] = $cart->cart_contents[ $cart_item_key ];

    }

    // Cart contents

    $cart->cart_contents = $cart_contents;

}

add_action( 'woocommerce_cart_loaded_from_session', 'sort_cart_specific_product_at_bottom', 10, 1 );

并且此代码确保基于 sku 的商品不会从购物车中移除

function prevent_cart_item_remove_link( $link, $cart_item_key ) {

    // Product sku that should not be removable

    $product_sku_last = array( 'lunchbox', 'pakket' );

    if( WC()->cart->find_product_in_cart( $cart_item_key ) ) {

        $cart_item = WC()->cart->cart_contents[ $cart_item_key ];

        // Get product sku

        $product_sku = $cart_item['data']->get_sku();

        // In_array — checks if a value exists in an array

        if ( in_array( $product_sku, $product_sku_last ) ) {

            $link = '';

        }

    }

    return $link;

}

add_filter( 'woocommerce_cart_item_remove_link', 'prevent_cart_item_remove_link', 10, 2 );
