在购物车和结帐时在WooCommerce产品名称中附加自定义字段值

我正在尝试更改购物车和结帐页面中的产品名称 .

我有以下代码来添加一些购物车元数据:

function render_meta_on_cart_and_checkout( $cart_data, $cart_item = null ) {
    $custom_items = array();
    /* Woo 2.4.2 updates */
    if( !empty( $cart_data ) ) {
        $custom_items = $cart_data;
    }

    if( isset( $cart_item['sample_name'] ) ) {
        $custom_items[] = array( "name" => $cart_item['sample_name'], "value" => $cart_item['sample_value'] );
    }
    return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );

但我也想改变产品的名称 .

例如,如果产品名称为 Apple 且自定义字段 'sample_value' 值为 with sugar ,我想获得 Apples (with sugar) .

我怎样才能做到这一点?

    使用挂钩在 woocommerce_before_calculate_totals 动作钩子中的自定义函数:

    // Changing the cart item price based on custom field calculation
    add_action( 'woocommerce_before_calculate_totals', 'customizing_cart_items_name', 20, 1 );
    function customizing_cart_items_name( $cart ) {
    
        if ( is_admin() && ! defined( 'DOING_AJAX' ) )
            return;
    
        if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
            return;
    
        // Loop through each cart items
        foreach ( $cart->get_cart() as $cart_item ) {
            // Continue if we get the custom 'sample_name' for the current cart item
            if( empty( $cart_item['sample_name'] ) ){
                // Get an instance of the WC_Product Object
                $product = $cart_item['data'];
                // Get the product name (Added compatibility with Woocommerce 3+)
                $product_name = method_exists( $product, 'get_name' ) ? $product->get_name() : $product->post->post_title;
                // The new string composite name
                $product_name .= ' (' . $cart_item['sample_name'] . ')';
    
                // Set the new composite name (WooCommerce versions 2.5.x to 3+)
                if( method_exists( $product, 'set_name' ) ) 
                    $product->set_name( $product_name );
                else
                    $product->post->post_title = $product_name;
            }
        }
    }
    

    代码在您的活动子主题(或主题)的function.php文件中或在任何插件文件中 .

    此代码经过测试并可以使用 .
