CodeIgniter 搜索分页有点问题 帮忙看下
我的查询条件比较多，所以可能稍微显得长了点，分页是可以用，但是点击下一页，跳转到第二页的时候，下面的当前页并不是第二页！请指教。

主要问题就是，点击下一页的时候，已经跳转到下一页，但是当前页显示不正确！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'])){
$data ['age']=$_POST['age'];
}
if(!empty($_POST['age2'])){
$data ['age2']=$_POST['age2'];
}
if(!empty($_POST['phone'])){
$data ['phone']=$_POST['phone'];
}
if(!empty($_POST['sex'])){
$data ['sex']=$_POST['sex'];
}
if(!empty($_POST['zxjb'])){
$data ['zxjb']=$_POST['zxjb'];
}
if(!empty($_POST['comefrom'])){
$data ['comefrom']=$_POST['comefrom'];
