使用ECShop搭建外貿站多國貨幣切換功能

//1   在數據庫裏的表ecs_shop_config插入


insert into ecs_shop_config('id','parent_id','code','type','store_range','store_dir','value','sort_order') values(null,'1','rate','text','','','1,0.71,0.69,6.85,1.45','1'),(null,'1','ybprice_format','text','','','&%s','1'),(null,'1','aprice_format','text','','','EUR%s','1'),(null,'1','cprice_format','text','','','￥%s','1'),(null,'1','aoprice_format','text','','','AU%s','1');
//INSERT INTO `ecs_shop_config`(`id`, `parent_id`, `code`, `type`, `store_range`, `store_dir`, `value`, `sort_order`) VALUES (null,'1','rate','text','','','1,0.71,0.69,6.85,1.45','1'),(null,'1','ybprice_format','text','','','&%s','1'),(null,'1','aprice_format','text','','','EUR%s','1'),(null,'1','cprice_format','text','','','￥%s','1'),(null,'1','aoprice_format','text','','','AU%s','1')




//2   在/languages/zh_cn/admin/shop_config.php下添加 (73行)
 
 $_LANG['cfg_name']['rate'] = '貨幣匯率';
 $_LANG['cfg_name']['ybprice_format'] = '英鎊格式';
 $_LANG['cfg_name']['aprice_format'] = '歐元格式';
 $_LANG['cfg_name']['cprice_format'] = '人民幣格式';
 $_LANG['cfg_name']['aoprice_format'] = '澳元格式';


//並且添加下面的幫助信息 (199行)


$_LANG['cfg_desc']['rate'] = '輸入規則按照和美元的匯率進行出入 Us,EURP,BriishPound,China,Austriliar';
$_LANG['cfg_desc']['ybprice_format'] = '顯示英鎊格式，%s將被替換爲相應的價格。';
$_LANG['cfg_desc']['aprice_format'] = '顯示歐元格式，%s將被替換爲相應的價格。';
$_LANG['cfg_desc']['cprice_format'] = '顯示人民幣格式，%s將被替換爲相應的價格。';
$_LANG['cfg_desc']['aoprice_format'] = '顯示澳元格式，%s將被替換爲相應的價格。';








//3.在themes/當前使用的模板文件夾/library/page_header.lbi的合適位置添加


<div class="TopNavList">

<option value="{$url_head}&currency=AUD">澳元</option>
</select>






//或
<div class="TopNavList">
<ul>
<li><a href="{$url_head}&currency=USD">美元</a><span></span></li>

<li><a href="{$url_head}&currency=AUD">澳元</a><span></span></li>
</ul>
</div>








//    4在/includes/init.php最後面添加 //路徑處理 


$url_this="http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?id=".@$_GET['id'];

//    5.在/includes/lib_commom.php找到這個函數price_format並且按下面的進行修改

// 6.修改表ecs_order_info


alter table 'ecs_order_info' add 'currency' varchar(10) not null,add 'new_money' decimal(10,2) not null








// 7.修改flow.php文件中

// 8.在\includes\modules\payment\paypal.php 大約92行一個get_code函數


function get_code($order,$payment){
