第一步 添加扩展函数 找到文件并且打开  /phpcms/libs/functions/extention.func.php 添加如下代码：

//判断设备  返回bool
function is_mobile() { 
    $user_agent = $_SERVER['HTTP_USER_AGENT']; 
    $mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte"); 
    $is_mobile = false; 
    foreach ($mobile_agents as $device) { 
        if (stristr($user_agent, $device)) { 
            $is_mobile = true; 
            break; 
        } 
    } 
    return $is_mobile; 
}

第二步 找到首页函数文件控制器，添加如下代码：

在$id = intval($_GET['id']);后面添加

$is_mobile = is_mobile(); //bool 
        //如果是手持设备 跳转手机页面 伪静态网址链接，自行定义
        if(!$is_mobile){

            $url = APP_PATH.'content-'.$catid.'-'.$id.'-1.html';
            echo "";
            exit;
        }

第三步 找到正文页函数文件控制器页面，添加如下代码：

if(!$catid || !$id) showmessage(L('information_does_not_exist'),'blank');后面添加

$is_mobile = is_mobile(); //bool 
        //如果是手持设备 跳转手机页面 
        if($is_mobile){
            switch ($catid) {
                case '6':
                    $typeid = '9';
                    break;
                case '7':
                    $typeid = '14';
                    break;
                // 。。。。 自行添加 参考图一

                default:
                    //code
                    break;
            }

            $url = 'http://m.lanrenmb.com/index.php?a=show&catid='.$catid.'&typeid='.$typeid.'&id='.$id;
            echo "";
            exit;
        }

第四步：首页进行自适应调整就可以了。
