opencart中文版checkout设置city和county为非必选

　　opencart中文版在opencart原版进行了一些修改，添加了适合国内使用的设置，但是并不适合国外用户，比如订单页面的收货地址添加了国内的城市和区县，而国外的city和county被删减了，这两项又是必选项，如何设置为非必填项呢？随ytkah一起来看看。本文中opencart版本为3.0.2.0中文版。

　　1、首先打开文件/catalog/controller/checkout/checkout.php，大概896行，找到shipping_city_id和shipping_county_id，注释掉error提示

if (!isset($this->request->post['shipping_city_id']) || (int)$this->request->post['shipping_city_id'] <= 0) {
//			$error['city'] = $this->language->get('error_city');
		}

		if (!isset($this->request->post['shipping_county_id']) || (int)$this->request->post['shipping_county_id'] <= 0) {
//			$error['county'] = $this->language->get('error_county');
		}

　　2、打开/catalog/view/theme/wist/template/checkout/checkout/_shipping_address.twig，大概69行，把required的class去掉，即

<div class="form-group required">

改为

<div class="form-group">
完整代码如下

      <div class="form-group ">
        <label class="col-sm-2 control-label" for="input-shipping-city">{{ entry_city }}</label>
        <div class="col-sm-10">
          <select name="shipping_city_id" id="input-shipping-city" class="form-control">
            <option value="">{{ text_select }}</option>
          </select>
        </div>
      </div>
      <div class="form-group ">
        <label class="col-sm-2 control-label" for="input-shipping-county">{{ entry_county }}</label>
        <div class="col-sm-10">
          <select name="shipping_county_id" id="input-shipping-county" class="form-control">
            <option value="">{{ text_select }}</option>
          </select>
        </div>
      </div>

　　保存上传，刷新缓存，再测试一下city和county是不是可以不用选了。
