woocommerce中的产品最小数量乘以7

Question

当用户在购物车上并希望在完成时验证最小金额时，我想在最终下订单。需要乘以 7。

例如.. 我店里有 20 种产品。最小产品数量是任何产品的 7 的乘积。

Ex:
Product with ID:3 & Quantity: 5
Product with ID:13 & Quantity: 2 
   => Total:7 = > Success

Product with ID:2 & Quantity: 3
Product with ID:6 & Quantity: 8
  => Total: 11 => Fail

Product with ID:1 & Quantity: 2
Product with ID:5 & Quantity: 8
Product with ID:11 & Quantity: 4
  => Total: 14 => Success

我该怎么做？这是我尝试过的

function wc_minimum_order_amount() {
    global $woocommerce;
    $minimum = 7;
    if ( $woocommerce->cart->get_cart_total() %  $minimum != 0) {
        $woocommerce->add_error( sprintf( 'You must have an order with a minimum of %s to place your order.' , $minimum ) );
    }
}

更新

您需要将您的功能挂钩 woocommerce_checkout_process，做你的计算和 显示错误。

类似这样的：

add_action('woocommerce_checkout_process', 'wh_wc_minimum_order_amount');

function wh_wc_minimum_order_amount()
{
    $minimum = 7;
    if (WC()->cart->get_cart_contents_count() % $minimum != 0)
    {
//      wc_clear_notices();
        wc_add_notice(sprintf('You must have an order with a minimum of %s to place your order.', $minimum), 'error');
    }
}

代码进入您的活动子主题（或主题）的functions.php 文件。或者也可以在任何插件 php 文件中。
代码已经过测试并且可以工作。

希望这会有所帮助！
