WordPress 主题开发 WooCommerce 设定最低订单量，显示一个通知提示客户：

1.     /**

2.      * Set a minimum order amount for checkout

3.      */

4.     add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );

5.     add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );

7.     function wc_minimum_order_amount() {

8.         https:// Set this variable to specify a minimum order value

9.         $minimum = 50;

11.         if ( WC()->cart->total < $minimum ) {

13.             if( is_cart() ) {

15.                 wc_print_notice(

16.                     sprintf( 'Your current order total is %s — you must have an order with a minimum of %s to place your order ' ,

17.                         wc_price( WC()->cart->total ),

18.                         wc_price( $minimum )

19.                     ), 'error'

20.                 );

22.             } else {

24.                 wc_add_notice(

25.                     sprintf( 'Your current order total is %s — you must have an order with a minimum of %s to place your order' ,

26.                         wc_price( WC()->cart->total ),

27.                         wc_price( $minimum )

28.                     ), 'error'

29.                 );

31.             }

32.         }

33.     }

但未达到最低金额时如何禁用结帐按钮？参考以下：

1.     add_action( 'woocommerce_check_cart_items', 'required_min_cart_subtotal_amount' );

2.     function required_min_cart_subtotal_amount() {

3.         https:// Only run in the Cart or Checkout pages

4.         if( is_cart() || is_checkout() ) {

6.             https:// HERE Set minimum cart total amount

7.             $min_total = 250;

9.             https:// Total (before taxes and shipping charges)

10.             $total = WC()->cart->subtotal;

12.             https:// Add an error notice is cart total is less than the minimum required

13.             if( $total <= $min_total  ) {

14.                 https:// Display an error message

15.                 wc_add_notice( '<strong>' . sprintf( __("A minimum total purchase amount of %s is required to checkout."), wc_price($min_total) ) . '<strong>', 'error' );

16.             }

17.         }

18.     }

将 PHP 代码放在主题或子主题 functions.php 文件的底部。
