Zencart 国家排序及中文名称的扩展

最终实现效果如上

具体步骤：

1. 手动或SQL修改数据表，增加2个字段

<span style="color: #0000ff;">ALTER</span> <span style="color: #0000ff;">TABLE</span> countries <span style="color: #0000ff;">ADD</span> `countries_name_cn` <span style="color: #0000ff;">VARCHAR</span>( <span style="color: #800000; font-weight: bold;">64</span> ) <span style="color: #0000ff;">NULL</span> <span style="color: #0000ff;">DEFAULT</span> <span style="color: #ff0000;">''</span>, <span style="color: #0000ff;">ADD</span> `order_by` <span style="color: #0000ff;">int</span>(<span style="color: #800000; font-weight: bold;">11</span>) <span style="color: #808080;">NOT</span> <span style="color: #0000ff;">NULL</span> <span style="color: #0000ff;">DEFAULT</span> <span style="color: #ff0000;">'</span><span style="color: #ff0000;">0</span><span style="color: #ff0000;">'</span>;

2. 修改admin/countries.php文件，增加表单插入编辑功能， 共计7处，此处忽略具体代码。

3. 之后还要修改两个获取国家下拉列表的函数（前台后台分别对应一个）

#includes/functions/functions_lookups.php

        </span><span style="color: #800080;">$countries_values</span>-><span style="color: #000000;">MoveNext();
      }
    }

    </span><span style="color: #0000ff;">return</span> <span style="color: #800080;">$countries_array</span><span style="color: #000000;">;

最终效果

如果不是特别需要，后台函数也可不修改。
