Php 如果 Select 的县不是store 所在的县，如何隐藏本地自提

例如，如果某人 Select 的任何县不是SORE所在的县，则从签出中禁用Local Pickup.

这是cart-shipping.php:

<?php
/**
 * Shipping Methods Display
 *
 * In 2.1 we show methods per package. This allows for multiple methods per order if so desired.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/cart/cart-shipping.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 3.6.0

global $cities;

$cities['RO'] = array(

    'AG' => array(

    'CJ' => array(
        'CLUJ-NAPOCA',
        'Apahida',
        'FLORESTI',
    ) ,
);

如果 Select 的县不是CJ(最后一个州)的城市，我想禁用Local pickup.
