destoon送给多城市或开设分站的朋友 城市切换

看到好多站有类似 猜您可能在西安， 点击进入西安站>>
如图：


所有搞了类似一个小功能，希望对需要的哥们AND妹妹有用。

第一步 ->  在 extend.func.php 内加入以下函数

1. <li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">function get_ip2city($ip){
   
2. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        global $db;
   
3. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        $city = ip2area($ip);
   
4. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        if(is_array($all_city = cache_read('allcity.php'))){
   
5. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">                foreach($all_city as $k => $v){
   
6. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">                        $v['name'] = str_replace(array("市","区"," "),array("","",""),$v['name']);
   
7. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">                        if(@strstr($city,$v['name'])){
   
8. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">                                return $v;
   
9. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">                        }
   
10. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">                }
    
11. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        }</li>

复制代码

第二步 -> api\city.php 的 $lists = array(); 上面添加 以下代码

1. $xxxx = get_ip2city($DT_IP);

复制代码

以下我临时用的是一下判断仅供参考，谁有好方法可以回复一下。

1. <li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">// $DT_IP = '113.132.197.181';  //本地临时测试的IP，实际使用时删除本行代码。
   
2. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">
   
3. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">if(get_ip2city($DT_IP)){
   
4. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        $xxxx = get_ip2city($DT_IP);
   
5. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">}else{
   
6. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        $xxxx['name'] = $L['allcity'];
   
7. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        $xxxx['domain'] = $xxxx['areaid'] = $xxxx['style'] = '';
   
8. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">}</li>

第三步 -> 在模版文件 city.htm 文件中 想添加的部分添加模版代码 高手可以无视模版代码

• 1. <li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;"><!--[ $xxxx 变量自行取名 我这里就用 xxxx 代替了 ]-->
     
  2. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;"><a href="{if $xxxx[domain]}{$xxxx[domain]}{else}javas<span style="box-sizing: border-box; word-break: break-all; text-size-adjust: none;">cript:gocity('areaid={$xxxx[areaid]}');{/if}">
     
  3. </span></li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        点击进入{set_style($xxxx[name], $xxxx[style])}站
     
  4. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;"></a></li>

或

1. <li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;"><!--[ $xxxx 变量自行取名 我这里就用 xxxx 代替了 ]-->
   
2. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;"><!--[ {if $xxxx}代码段{/if} 判断当前城市是否开通了分站的，高手可以无视模版代码 ]-->
   
3. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">{if $xxxx}
   
4. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none; font-family: Monaco, Consolas, " lucida="" console",="" "courier="" new",="" serif;="" font-size:="" 12px;="" color:="" rgb(51,="" 102,="" 153);="" background-image:="" initial;="" background-position:="" background-size:="" background-repeat:="" background-attachment:="" background-origin:="" background-clip:="" initial;"=""><a href="{if $xxxx[domain]}{$xxxx[domain]}{else}javas<span style="box-sizing: border-box; word-break: break-all; text-size-adjust: none;">cript:gocity('areaid={$xxxx[areaid]}');{/if}">
   
5. </span></li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">        点击进入{set_style($xxxx[name], $xxxx[style])}站
   
6. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;"></a>
   
7. </li><li style="box-sizing: border-box; word-break: break-all; text-size-adjust: none; margin-left: 0px; list-style: none;">{/if}</li>
