WooCommerce：在一定数量的已完成订单或一个订单中的最小数量后自动更改用户角色

如何解决WooCommerce：在一定数量的已完成订单或一个订单中的最小数量后自动更改用户角色

我想在之后自动将用户角色更改为高级

• 3个已完成的订单
• 一次消费至少500现金

我在互联网上找到了这两个代码段：

function change_privategroup_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 ) {

              // Insert the Product IDs Here. If Multiple Products seperate by ||
      if ( $product_id == '7026' || $product_id == '7027' || $product_id == '7028' || $product_id == '7029') {

                  // Mention the group number below. Here it is group1.
                  update_user_meta( $order->user_id,'private_group','group1');

      }
    }
}
}
add_action( 'woocommerce_order_status_processing','change_privategroup_on_purchase' );

---

然后访问订单历史记录：

来源：Checking if customer has already bought something in WooCommerce

function has_bought() {
    // Get all customer orders
    $customer_orders = get_posts( array(
        'numberposts' => 3,// one order is enough
        'meta_key'    => '_customer_user','meta_value'  => get_current_user_id(),'post_type'   => 'shop_order',// WC orders post type
        'post_status' => 'wc-completed',// Only orders with "completed" status
        'fields'      => 'ids',// Return Ids "completed"
    ) );

    // return "true" when customer has already at least one order (false if not)
   return count($customer_orders) > 3 ?  true : false; 
}

我如何调整它们使其起作用？ 先感谢您 ！ ：）

解决方法

• 通过completed orders获取user id数的自定义函数基于get_order_count( &$customer );

/**
 * Return the number of orders this customer has.
 *
 * @since 3.0.0
 * @param WC_Customer $customer Customer object.
 * @return integer
 */
public function get_order_count( &$customer ) {
    $count = get_user_meta( $customer->get_id(),'_order_count',true );

    if ( '' === $count ) {
        global $wpdb;

        $count = $wpdb->get_var(
            // phpcs:disable WordPress.DB.PreparedSQL.NotPrepared
            "SELECT COUNT(*)
            FROM $wpdb->posts as posts
            LEFT JOIN {$wpdb->postmeta} AS meta ON posts.ID = meta.post_id
            WHERE   meta.meta_key = '_customer_user'
            AND     posts.post_type = 'shop_order'
            AND     posts.post_status IN ( '" . implode( "','",array_map( 'esc_sql',array_keys( wc_get_order_statuses() ) ) ) . "' )
            AND     meta_value = '" . esc_sql( $customer->get_id() ) . "'"
            // phpcs:enable
        );
        update_user_meta( $customer->get_id(),$count );
    }

    return absint( $count );
}

所以我们得到

• 可以通过设置调整条件
• usermeta表中使用了一个标志，这样，如果一个人已经是高级成员，则不必不必要地重新运行整个代码
• woocommerce_order_status_completed钩子-Woocommerce订单完成后，此钩子更改字段值
• 通过代码中的注释进行解释
