将自定义元数据保存到Woocommerce订单

在WooCommerce中,我向具有工具集类型的产品添加了2个字段。因此,当您添加产品时,可以设置几天或几周的预期交货时间。

在购物车和检阅页面上,我编写了一些代码以在合计表中显示最长的交货时间。

Front-end layout

我通过在cart-totals.php和review-order.php的结束表格标记之前添加以下代码来完成此操作(当然,我已将其添加到我的子主题中)。

     foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
                $product_id = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );

                $amount_of_days = 0;

                $delivery_amount = get_post_meta($product_id, 'wpcf-aantal', true);
                $delivery_week_or_days = get_post_meta($product_id, 'wpcf-dagen-of-weken', true);

                if($delivery_week_or_days == "weken"){
                    $amount_of_days = $delivery_amount * 7;
                } else {
                    $amount_of_days = $delivery_amount;
                }
                $array_of_days[] = $amount_of_days;
    }

    $most_days = max($array_of_days);

    if ($most_days % 7 == 0){
        $most_time_string = $most_days/7 . ' weken';
    } else {
        $most_time_string = $most_days . ' dagen';
    }

    if (!empty($most_days)){

        echo '<tr class="custom-cart-delivery-time">';
            echo '<th>Geschatte levertijd</th>';
            echo '<td>' . $most_time_string. '</td>';
        echo '</tr>';
    }

我的问题是,我实际上如何确保订单安全?我希望在订单和发票中显示预计的运输时间(例如:“ 3周”或“ 2天”)。

答案 0 :(得分:1)

您可以尝试使用以下内容(注释):

// Utility function to get the "most day" value from cart object (cart items)
function get_the_most_day(){
    $array_of_days = []; // Initializing;

    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        $delivery_amount       = get_post_meta($cart_item['product_id'], 'wpcf-aantal', true);
        $delivery_week_or_days = get_post_meta($cart_item['product_id'], 'wpcf-dagen-of-weken', true);
        $amount_of_days        = 0;

        $array_of_days[] = $delivery_week_or_days == "weken" ? $delivery_amount * 7 : $delivery_amount;
    }
    $most_days = max($array_of_days);

    return $most_days % 7 == 0 ? $most_days / 7 . ' weken' : $most_days . ' dagen'; 
}

// Save the most day in Woocommerce session (on checkout page)
add_action( 'template_redirect', 'save_most_days_in_wc_session' );
function save_most_days_in_wc_session() {
    // Only checkout page
    if( is_checkout() && ! is_wc_endpoint_url() ){
        WC()->session->set( 'most_day', get_the_most_day() );
    }
}

// Save the most day as custom meta data in the order
add_action('woocommerce_checkout_create_order', 'save_the_most_day_as_order_meta_data', 20, 2);
function save_the_most_day_as_order_meta_data( $order, $data ) {
    if( $most_day = WC()->session->get( 'most_day' ) ){
        $order->update_meta_data( '_most_day', $most_day );
    }
}

代码进入您的活动子主题(或活动主题)的function.php文件中。应该可以。


要获得“一天的最高价值” (两种方式)

1)从WC_Order $order变量Object

$most_day_value = get_meta( '_most_day' );

2)从动态订单ID变量

$most_day_value = get_post_meta( $order_id, '_most_day', true );
