Codeigniter auto suggestion text box - codeigniter

Question

I'm using codeigniter in my project and want to implement a text box which suggests related word s from the data base. In this one I want to get the ID of the selected vehicle. But so far I was only able to retrieve the vehicle names with out IDs.
The code so far,
Model
function searchVehicle($name){
$this->db->like('Name', $name, 'both');
return $this->db->get('vw_vehicle_search')->result();
}
Controller
public function vehicle_search(){
$this->load->model('model_vehicle');
if(isset($_GET['term'])){
$result = $this->model_vehicle->searchVehicle($_GET['term']);
if(count($result)>0){
foreach($result as $object)
$arr_result[] = $object->Name;
echo json_encode($arr_result);
}
}
}
View
<script type="text/javascript">
$(document).ready(function(){
$('#vehicle_name').autocomplete({
source: "<?php echo base_url();?>vehicle/vehicle_search/?"
});
});
</script>
<div class="col-md-4">
<?php
$input_data = array(
'name' => 'vehicle_name',
'id' => 'vehicle_name',
'class' => 'form-control'
);
echo form_input($input_data)?>
</div>
How can I pass the id of the vehicle with this one and get the id when i select a vehicle to insert to the db.
Thank you.

Try it in this way:
controller:
public function vehicle_search(){
$this->load->model('model_vehicle');
if(isset($_GET['term'])){
$result = $this->model_vehicle->searchVehicle($_GET['term']);
if(count($result)>0){
foreach($result as $object)
$arr_result[] = array( 'label' => $object->Name, 'value' => $object->id);
echo json_encode($arr_result);
}
}
}
View:
$(document).ready(function(){
$('#vehicle_name').autocomplete({
source: "<?php echo base_url();?>vehicle/vehicle_search/?",
select: function(event, ui) {
event.preventDefault();
$("#vehicle_name").val(ui.item.label);
//$("#vehicle_name-hidden").val(ui.item.value);
},
focus: function(event, ui) {
event.preventDefault();
$("#vehicle_name").val(ui.item.label);
}
});
});
