在 Woocommerce 中为特定用户角色设置最小订单量

Question

我正在创建一个批发网站。看这里，我已经能够找到在客户首次下订单后在两个用户角色之间切换的代码。现在我只需要能够在购物车/结帐页面上为不同的用户角色设置最低订单金额，而我发现的大部分内容都比我需要的要多得多。在网上搜索我能找到这段代码：

<?php
/*
Author: Doug Edgington
Description: Require a minimum order total in Woocommerce for a user role
*/
function dee_minimum_order_total_required() {
    if( is_user_logged_in() ) { 
        global $woocommerce;
        global $current_user;

        get_currentuserinfo();

        $dee_user_roles = $current_user->roles;
        $dee_user_role = array_shift($dee_user_roles);

        $dee_minimum = 50;
        if ( $woocommerce->cart->subtotal < $dee_minimum  && $dee_user_role == 'wholesale_buyer') {
            $woocommerce->add_error( sprintf( 'Wholesale users must have a minimum order total of $%s to place an order.' , $dee_minimum ) );
        }
    } //end main if statement
}
add_action( 'woocommerce_checkout_process', 'dee_minimum_order_total_required' );

如何向此代码添加 1 个以上的用户角色？

Answer 1

您使用的代码非常陈旧且过时。下面的代码将检查应具有最小订单量的 Wholesale 用户角色的购物车项目：

// Cart and checkout validation
add_action( 'woocommerce_check_cart_items', 'minimal_total_required' ); // Cart and Checkout
add_action( 'woocommerce_checkout_process', 'minimal_total_required' ); // Checkout (optional)
function minimal_total_required() {
    $user = wp_get_current_user();

    ## -- YOUR SETTINGS BELOW -- ##

    $min_amount    = 50; // Minimal order amount
    $targeted_role = 'wholesale_buyer'; // User role

    // Exit for non logged users or when minimal order amout is reached
    if( $user->ID == 0 || WC()->cart->subtotal >= $min_amount ) 
        return; 

    // Display an error notice for Wholesale user role
    if ( in_array( $targeted_role, $user->roles ) ) 
        wc_add_notice( sprintf( __("As a Wholesale user you must have a minimal order total of %s.") , wc_price($min_amount) ), 'error' );
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。经过测试并且可以工作。

对于两个用户角色和两个最小数量，您将使用以下内容：

// Cart and checkout validation
add_action( 'woocommerce_check_cart_items', 'minimal_total_required' ); // Cart and Checkout
add_action( 'woocommerce_checkout_process', 'minimal_total_required' ); // Checkout (optional)
function minimal_total_required() {
    $user = wp_get_current_user();

    // Exit for non logged users
    if( $user->ID == 0 ) return;

    ## -- YOUR SETTINGS BELOW (For 2 user roles and 2 minimal amounts) -- ##

    $min_amount    = array( 50, 40 ); // Minimal order amounts
    $targeted_role = array('wholesale_buyer', 'customer'); // Targetted User roles

    $cart_subtotal  = WC()->cart->subtotal;

    // Wholesale user
    if ( in_array( $targeted_role[0], $user->roles ) && $cart_subtotal < $min_amount[0]){
        $text = sprintf( __('As a Wholesale user you must have a minimal order total amount of %s.'), wc_price($min_amount[0]) );
    }
    // Customer user
    elseif ( in_array( $targeted_role[1], $user->roles ) && $cart_subtotal < $min_amount[1]){
        $text = sprintf( __('You must have a minimal order total amount of %s.'), wc_price($min_amount[1]) );
    }

    // Display an error notice for Wholesale user role
    if( isset($text) )
        wc_add_notice( $text, 'error' );
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。经过测试并且可以工作。

它将为每个用户角色显示不同的通知。
