CodeIgniter 搜尋分頁有點問題 幫忙看下
我的查詢條件比較多，所以可能稍微顯得長了點，分頁是可以用，但是點擊下一頁，跳轉到第二頁的時候，下面的當前頁並不是第二頁！請指教。

主要問題就是，點擊下一頁的時候，已經跳轉到下一頁，但是當前頁顯示不正確！控制器
PHP codefunction people_daozhen($askdate,$askdate2,$name,$age,$age2,$phone,$sex,$zxjb,$comefrom,$area){


if(!empty($_POST['askdate'])){
$data ['askdate']=$_POST['askdate'];
}

if(!empty($_POST['askdate2'])){
$data ['askdate2']=$_POST['askdate2'];
}
if(!empty($_POST['name'])){
$data ['name']=$_POST['name'];
}
if(!empty($_POST['age'])){
