Woocommerce中的累积最小购物车数量限制

Question

在Woocommerce中，我想在客户结账之前设定一些要求得到批准。我希望客户在进行结账前有6个数量。
数量与一种产品无关，它们可以组合更多的产品，直到达到总量。
如果恰好有6个，则可以继续。下一阶段，必须有正好12个数量才能结账（例如在购物车中有8个数量），之后18个，24个等......

我正在使用此功能，仅适用于6项数量计数限制。我想用之前解释的逻辑扩展功能，使其具有动态性和渐进性。

我的实际代码：

// Set a minimum number of products requirement before checking out
add_action( 'woocommerce_check_cart_items', 'spyr_set_min_num_products' );
function spyr_set_min_num_products() {
    // Only run in the Cart or Checkout pages
    if( is_cart() || is_checkout() ) {
        global $woocommerce;

        // Set the minimum number of products before checking out
        $minimum_num_products = 6;
        // Get the Cart's total number of products
        $cart_num_products = WC()->cart->cart_contents_count;

        // Compare values and add an error is Cart's total number of products
        // happens to be less than the minimum required before checking out.
        // Will display a message along the lines of
        // A Minimum of 20 products is required before checking out. (Cont. below)
        // Current number of items in the cart: 6   
        if( $cart_num_products < $minimum_num_products ) {
            // Display our error message
            wc_add_notice( sprintf( '<strong>A Minimum of %s products is required before checking out.</strong>' 
                . '<br />Current number of items in the cart: %s.',
                $minimum_num_products,
                $cart_num_products ),
            'error' );
        }
    }
}

任何帮助都将非常感激。

以下是在订单状态更改时计算用户动态累进料品数量限制的方法，并根据数字6（6）增加步骤。

此外，数量必须是六（6）的倍数。

代码：

// User dynamic progressive item quantity count limitation
add_action( 'woocommerce_check_cart_items', 'user_dynamic_progressive_min_item_qty_count_limitation' );
function user_dynamic_progressive_min_item_qty_count_limitation() {
    // Only in the Cart or Checkout pages
    if( ! ( is_cart() || is_checkout() ) ) return; // Exit

    $base_step = 6; // The quantity step base
    $user_id   = get_current_user_id(); // User ID
    $min_qty   = get_user_meta( $user_id, '_min_item_qty_ref', true ); // Get min qty from user data
    $min_qty   = $user_id == 0 ? $base_step : ( empty($min_qty) ? $base_step : $min_qty );
    $qty_count = (int) WC()->cart->get_cart_contents_count(); // cart items count

    if( $qty_count < $min_qty ):

    // Display an error notice when quantity count is below the minimum
    wc_add_notice( sprintf( '<strong>A Minimum of %s products is required before checking out.</strong>'
        . '<br />Current number of items in the cart: %s.', $min_qty, $qty_count ), 'error' );

    elseif( ( $qty_count % 6 ) != 0 ):

    // Display an error notice when quantity count is not a multiple of 6
    wc_add_notice( sprintf( '<strong>A Multiple of %s products is required before checking out.</strong>'
        . '<br />Current number of items in the cart: %s.', $base_step, $qty_count ), 'error' );

    endif;
}

// User dynamic progressive item quantity count calculation (increase or decrease) on order status change
add_action('woocommerce_order_status_changed', 'user_dynamic_progressive_min_item_qty_calculation', 50, 4 );
function user_dynamic_progressive_min_item_qty_calculation( $order_id, $old_status, $new_status, $order ){

    $statuses_increase_limit = array('on-hold', 'processing', 'completed'); // Succesful statuses
    $statuses_decrease_limit = array('cancelled', 'failed'); // Negative statuses (decreasing)

    $min_qty_step = 6; // The quantity step base
    $customer_id  = (int) $order->get_customer_id(); // User ID
    $user_min_qty = (int) get_user_meta( $customer_id, '_min_item_qty_ref', true ); // Get min qty from user data
    $order_flag   = get_post_meta( $order_id, '_min_item_qty_flag', true ); // Get order min qty flag
    $order_flag   = empty($order_flag) ? false : $order_flag;

    if ( in_array($new_status, $statuses_increase_limit) && ! $order_flag )
    {
        $user_min_qty = $user_min_qty == 0 ? $min_qty_step : $user_min_qty;

        update_post_meta( $order_id, '_min_item_qty_flag', true );
        update_user_meta( $customer_id, '_min_item_qty_ref', $user_min_qty + $min_qty_step  ); // Increase
    }
    elseif ( in_array($new_status, $statuses_increase_limit) && $order_flag )
    {
        update_post_meta( $order_id, '_min_item_qty_flag', false );
        update_user_meta( $customer_id, '_min_item_qty_ref', $user_min_qty - $min_qty_step ); // Decrease
    }
}

代码放在活动子主题（或活动主题）的function.php文件中。经过测试和工作。

  

下订单时，计算会增加最小项数量限制计数，并在用户数据中设置。订单已标记。如果订单被取消或失败，它将检查订单标志，如果设置了标志，它将减少最小项目数量限制计数。
