<input type="submit" name="submit" id="submit" value="short"/>
shortlist.php
$uid = explode(",",$this->input->post('uid'));
foreach($uid as $user_id)
{
$data = array('shortlist'=>'1');
$this->db->where('uid',$user_id);
$query = $this->db->update('personal_detail',$data);
}

You need to find all checkbox state respect to userid.
$(document).ready(function(){
$("#submit").click(function(e){
e.preventDefault();
var uids = [];
$("input[name='user_id']").map(function() {
uids.push({id: this.id, value: this.checked ? 1 : 0});
});
$.ajax({
type:"POST",
data:{"uid":uids},
url:"<?php echo base_url(); ?>hr/shortlist",
success:function(data){
setTimeout(function(){
location.reload();
}, 1000);
}
});
});
});
Now in shortlist.php
$uid = $this->input->post('uid');
foreach($uid as $user)
{
$data = array('shortlist'=> $user['value']);
$this->db->where('uid',$user['id']);
$query = $this->db->update('personal_detail',$data);
}
