在 WooCommerce 中设置特定产品或类别的最低订单金额

Question

我已经广泛搜索，看看其他人是否有这种情况，但没有运气得到答案。

本质上，我有两件商品可以添加到他们的购物车中。我想做到这一点，这样如果他们的小计不超过 15 美元或更多，他们就无法结账。

能够将他们的 ID 放入代码中就可以了。或者，我可以将它们分配到同一类别并按类别设置此最小值。

到目前为止，我只有设置通用最小值的基本 PHP。我只是需要一些帮助来弄清楚如何限制它以满足我的需要。

我是设计师而不是开发人员，因此非常感谢您的帮助。

    // Set a minimum dollar amount per order
add_action( 'woocommerce_check_cart_items', 'spyr_set_min_total' );
function spyr_set_min_total() {
    // Only run in the Cart or Checkout pages
    if( is_cart() || is_checkout() ) {
        global $woocommerce;

        // Set minimum cart total
        $minimum_cart_total = 10;

        // Total we are going to be using for the Math
        // This is before taxes and shipping charges
        $total = WC()->cart->subtotal;

        // Compare values and add an error is Cart's total
        // happens to be less than the minimum required before checking out.
        // Will display a message along the lines of
        // A Minimum of 10 USD is required before checking out. (Cont. below)
        // Current cart total: 6 USD 
        if( $total <= $minimum_cart_total  ) {
            // Display our error message
            wc_add_notice( sprintf( '<strong>A Minimum of %s %s is required before checking out.</strong>'
                .'<br />Current cart\'s total: %s %s',
                $minimum_cart_total,
                get_option( 'woocommerce_currency'),
                $total,
                get_option( 'woocommerce_currency') ),
            'error' );
        }
    }
}

仅针对购物车和结帐页面设置购物车中某些产品类别或产品 ID 的最小值。

这个未经测试的代码段由 this and this from wooThemes, and this too 组成：

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );
 
function wc_minimum_order_amount() {
    ##  SETTINGS  ##
    $minimum_amount = 50; // Define a minimum order amount
    $category_ids   = array( 17, 18 ); // Define your category ids in the array (or an empty array to disable)
    $product_ids    = array( 64, 67, 78 ); // Define your product ids in the array (or an empty array to disable)

    // Only on cart or checkout pages
    if( WC()->cart->is_empty() || ! ( is_cart() || is_checkout() ) ) 
        return; // Exit

    $total_amount = WC()->cart->subtotal; // Items subtotal including taxes

    if ( $total_amount < $minimum_amount ) {
        $needs_minimum_amount = false; // Initializing

        // Loop through cart items
        foreach ( WC()->cart->get_cart() as $cart_item ) {
            $product_id   = $cart_item['product_id'];
            $variation_id = $cart_item['variation_id'];
            
            // 1. Check for matching product categories
            if( sizeof($category_ids) > 0 ) {
                $taxonomy = 'product_cat';

                if ( has_term( $category_ids, $taxonomy, $product_id ) ) { 
                    $needs_minimum_amount = true;
                    break; // Stop the loop
                }
            }

            // 2. Check for matching product Ids
            if( sizeof($product_ids) > 0 ) {
                if ( array_intersect( $product_ids, array($product_id, $variation_id) ) ) { 
                    $needs_minimum_amount = true;
                    break; // Stop the loop
                }
            }
        }

        if( $needs_minimum_amount ) {
            wc_print_notice( sprintf( 
                __("You must have an order with a minimum of %s to place your order. Your current order total is %s."), 
                wc_price( $minimum_amount ), 
                wc_price( $total_amount )
            ), 'error' );
        }
    }
}

代码进入您的活动子主题（活动主题）的 functions.php 文件。已测试并有效。

您可以设置类别 ID、产品 ID 和最低订单金额。

This hooks are working for messages. But to avoid users from clicking you need to add Javascript/jQuery and maybe with ajax too (client side detection).
