Laravel Autocomplete using foreign key to show data from another table - mysql

Question

i have created an auto complete search box in controller of 'booking' table successfully , but i want the auto complete search box to show data from another table 'patient' that have a one to many relationship with "booking" table according to a specific condition using 'where' condition ,
This is the Booking Controller that i add autocomplete in it:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Booking;
use App\Patient;
use App\User;
use Session;
use DB;
use Auth;
use Input;
class BookingController extends Controller
{
public function __construct()
{
$this->middleware('auth');
}
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
$search = \Request::get('search');
$bookings = Booking::whereHas('patient', function ($query) use ($search) {
$query->where('patient_name', 'like', '%' . $search . '%');
})->where('status','=', null)->whereHas('patient', function ($query){
$query->where('company_id','=' ,Auth::user()->company_id);
})->paginate(10);
return view('booking.index')->withBookings($bookings);
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function autoComplete(Request $request) {
$query = $request->get('term','');
$bookings=Booking::whereHas('patient', function ($query){
$query->where('company_id','=' ,Auth::user()->company_id);
})->$data=array();
foreach ($bookings as $booking) {
$data[]=array('value'=>$booking->patient->patient_name,'id'=>$booking->id);
}
if(count($data))
return $data;
else
return ['value'=>'No Result Found','id'=>''];
}
and this is the Booking Model :
class Booking extends Eloquent
{
public function patient()
{
return $this->belongsTo('App\Patient');
}
public function user()
{
return $this->belongsTo('App\User');
}
}
and this is the patient Model:
class Patient extends Eloquent
{
public function booking()
{
return $this->hasMany('App\Booking');
}
public function user()
{
return $this->belongsTo('App\User');
}
}
and i used this code in view :
{!! Form::text('search_text', null, array('placeholder' => 'Search Text','class' => 'form-control','id'=>'search_text')) !!}
i want to show data from "patient" table and there is a one to many relationship between "booking" and "patient" table and i have successfully made a search box to search in patient table as you can see in index function , but i dont know to show data from "patient" table using where condition to show patient_name that his company_id equal Authenticated user company_id
Sorry for my Bad Language .
