php - 基于用户角色的 Woocommerce 最低订单总额

Question

我正在使用来自 Woocommerce Minimum Order Amount 的片段代码设置最低订单总额。但我想为每个用户角色设置不同的最小值。
我有一些自定义用户角色:wholesale_prices , wholesale_vat_exc , 和 distributor_prices .我想让代码根据使用角色来工作，每个角色的最低金额不同。
这是我的代码:

// Minimum order total

add_action( 'woocommerce_check_cart_items', 'wc_minimum_order_amount' );
 
function wc_minimum_order_amount() {
    // Set this variable to specify a minimum order value
    $minimum = 300;

    if ( WC()->cart->subtotal < $minimum ) {

        if( is_cart() ) {

            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 ), 
                    wc_price( WC()->cart->subtotal )
                ), 'error' 
            );

        } else {

            wc_add_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 ), 
                    wc_price( WC()->cart->subtotal )
                ), 'error' 
            );

        }
    }

使用 Wordpress 条件函数 current_user_can()喜欢:

add_action( 'woocommerce_check_cart_items', 'wc_minimum_order_amount' );
function wc_minimum_order_amount() {
    // minimum order value by user role
    if ( current_user_can('distributor_prices') )
        $minimum = 3000; 
    elseif ( current_user_can('wholesale_prices') )
        $minimum = 1000;
    elseif ( current_user_can('wholesale_vat_exc') )
        $minimum = 600;
    else 
        $minimum = 300; // default

    if ( WC()->cart->subtotal < $minimum ) {

        if( is_cart() ) {
            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 ), 
                wc_price( WC()->cart->subtotal )
            ), 'error' );
        } else {
            wc_add_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 ), 
                wc_price( WC()->cart->subtotal )
            ), 'error' );
        }
    }
}

代码位于事件子主题(或事件主题)的 functions.php 文件中。它应该有效。
