我为添加的自定义端点创建代码段，下面是我的代码：

 * Register new endpoint to use inside My Account page.
 *
 * @see https://developer.wordpress.org/reference/functions/add_rewrite_endpoint/
 */
function my_subscriptions_endpoints() {
    add_rewrite_endpoint( \'my-subscriptions\', EP_ROOT | EP_PAGES );

 * @param array $vars
 * @return array
 */
function my_subscriptions_query_vars( $vars ) {
    $vars[] = \'my-subscriptions\';

    return $vars;
}
add_filter( \'query_vars\', \'my_subscriptions_query_vars\', 0 );


/**
 * Flush rewrite rules on theme activation.
 */
function my_subscriptions_flush_rewrite_rules() {
    add_rewrite_endpoint( \'my-subscriptions\', EP_ROOT | EP_PAGES );
    flush_rewrite_rules();
}
add_action( \'after_switch_theme\', \'my_subscriptions_flush_rewrite_rules\' );

    // Search for the item position and +1 since is after the selected item key.
    $position = array_search( $after, array_keys( $items ) ) + 1;

    // Insert the new item.
    $array = array_slice( $items, 0, $position, true );
    $array += $new_items;
    $array += array_slice( $items, $position, count( $items ) - $position, true );

    return $array;
}
