根据在Woocommerce中购买的商品总数更改用户角色

Question

在Woocommerce中，我试图结合这两个功能：

第一个获取用户订购的商品总数（一直）

function get_user_total_purchased_items( $user_id = 0 ){
    global $wpdb;

    $customer_id = $user_id === 0 ? get_current_user_id() : (int) $user_id;

    return (int) $wpdb->get_var( "
        SELECT SUM(woim.meta_value)
        FROM {$wpdb->prefix}woocommerce_order_items AS woi
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
        INNER JOIN {$wpdb->prefix}posts as p ON woi.order_id = p.ID
        INNER JOIN {$wpdb->prefix}postmeta as pm ON woi.order_id = pm.post_id
        WHERE woi.order_item_type = 'line_item'
        AND p.post_type LIKE 'shop_order'
        AND p.post_status IN ('wc-completed')
        AND pm.meta_key LIKE '_customer_user'
        AND pm.meta_value LIKE '$customer_id'
        AND woim.meta_key LIKE '_qty'
    " );
}

如果用户订购某项商品，第二种更改用户角色。

function change_role_on_purchase( $order_id ) {

    $order = new WC_Order( $order_id );
    $items = $order->get_items();

    foreach ( $items as $item ) {
        $product_name = $item['name'];
        $product_id = $item['product_id'];
        $product_variation_id = $item['variation_id'];

        if ( $order->user_id > 0 && $product_id == '416' ) {
            update_user_meta( $order->user_id, 'paying_customer', 1 );
            $user = new WP_User( $order->user_id );

            // Remove role
            $user->remove_role( 'subscriber' ); 

            // Add role
            $user->add_role( 'premium' );
        }
    }
}

add_action( 'woocommerce_order_status_processing', 'change_role_on_purchase' );

我要完成的工作是，如果用户总共订购了50-99件商品，那么他的用户角色将从“标准用户”更改为“青铜用户”；如果订购了100-199件，他的用户角色“青铜用户-> silver_user”，并且商品总数超过200用户角色silver_user-> gold_user。

第一个功能运行良好，并且来自此答案 。

现在，只想弄清楚如何将其实现到第二个函数中。

由于Woocommerce 3，您的代码有些过时了，需要进行一些更改。 以下内容应根据购买的商品数量（未试用）有条件地更改用户角色：

function get_user_total_purchased_items( $user_id = 0 ){
    global $wpdb;

    $customer_id = $user_id === 0 ? get_current_user_id() : (int) $user_id;

    return (int) $wpdb->get_var( "
        SELECT SUM(woim.meta_value)
        FROM {$wpdb->prefix}woocommerce_order_items AS woi
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
        INNER JOIN {$wpdb->prefix}posts as p ON woi.order_id = p.ID
        INNER JOIN {$wpdb->prefix}postmeta as pm ON woi.order_id = pm.post_id
        WHERE woi.order_item_type = 'line_item'
        AND p.post_type LIKE 'shop_order'
        AND p.post_status IN ('wc-completed')
        AND pm.meta_key LIKE '_customer_user'
        AND pm.meta_value LIKE '$customer_id'
        AND woim.meta_key LIKE '_qty'
    " );
}

add_action( 'woocommerce_order_status_processing', 'change_role_on_purchase', 20, 2 );
function change_role_on_purchase( $order_id, $order ) {

    $user_id   = $order->get_customer_id();
    $user      = new WP_User( $user_id );
    $purchases = get_user_total_purchased_items( $user_id );

    if( $purchases >= 50 &&  $purchases < 100 && ! in_array( 'bronze_user', $user->roles ) ) {
        // Remove role
        $user->remove_role( 'subscriber' );

        // Add role
        $user->add_role( 'bronze_user' );
    }
    elseif( $purchases >= 100 &&  $purchases < 200 && ! in_array( 'silver_user', $user->roles ) ) {
        // Remove role
        $user->remove_role( 'bronze_user' );

        // Add role
        $user->add_role( 'silver_user' );
    }
    elseif( $purchases >= 200 && ! in_array( 'gold_user', $user->roles ) ) {
        // Remove role
        $user->remove_role( 'silver_user' );

        // Add role
        $user->add_role( 'gold_user' );
    }

    if ( $user_id > 0 && $product_id == '416' ) {
        foreach ( $order->get_items() as $item ) {
            if ( $order->user_id > 0 && $item->get_product_id() == '416' ) {
                update_user_meta( $user_id, 'paying_customer', 1 );

                // Remove role
                $user->remove_role( 'subscriber' );

                // Add role
                $user->add_role( 'premium' );
            }
        }
    }
}

代码进入您的活动子主题（或活动主题）的function.php文件中。 我希望它能正常工作，因为我无法对其进行测试。
