WooCommerce：完成一定数量的订单或一个订单中的最低金额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用户角色

• 3已完成订单

• 一笔订单消费满500现金

我在互联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' );

这是访问订单历史记录的一个：

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发挥作用？

Answer 1

获取by数量的自定义函数completed orders是user id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 );}所以我们得到条件可以通过设置进行调整usermeta 表中使用了一个标志，因此如果一个人已经是高级会员，则整个代码不会不必要地重新运行woocommerce_order_status_completed使用钩子 - 此钩子在 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// Based on https://github.com/woocommerce/woocommerce/blob/85a077b939b44500fc01b68d34e711117545f586/includes/data-stores/class-wc-customer-data-store.php#L349-L377function total_completed_orders( $the_user_id ) {    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 = 'wc-completed'        AND     meta_value = '" . esc_sql( $the_user_id ) .
