WooCommerce：在完成一定数量的订单或一个订单中的最小数量后自动更改用户角色

Question

我想在

之后自动将用户角色更改为高级

• 3 已完成 个订单
• 一笔订单至少消费 500 现金

我在网上找到了这两个代码片段：

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' );

还有这个访问订单历史记录：

来源：

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; 
}

我如何调整它们以使其工作？ 先感谢您 ！ :)

Answer 1

• user id获取completed orders个数的自定义函数是基于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(), '_order_count', $count );
    }

    return absint( $count );
}

所以我们得到

• 可通过设置调整条件
• 在 usermeta 中使用了一个标志 table，这样如果已经是高级会员就不会不必要地重新运行整个代码
• woocommerce_order_status_completed 使用挂钩 - 此挂钩在 Woocommerce 订单完成后更改字段值
• 通过代码中添加的注释进行解释
