autocomplete No Result found in laravel - mysql

Question

I have two table "patient" and "booking" table, and there is a relationship "One to Many" between them, I want to set up a search form in an index_booking page where a user can type a patient_name on it and auto complete show all patient_name from patient table according to WHERE Condition.
This is Booking Model
class Booking extends Eloquent
{
public function patient()
{
return $this->belongsTo('App\Patient');
}
public function user()
{
return $this->belongsTo('App\User');
}
}
This is 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 index page of booking
{!! Form::text('search_text', null, array('placeholder' => 'Search Text','class' => 'form-control','id'=>'search_text')) !!}
i used this code in Booking Controller to make autocomplete to show data
from patient table:
public function autoComplete(Request $request)
{
$patients = Patient::where('company_id', Auth::user()->company_id)
->where('patient_name', 'like', "&{$request->get('term')}&")
->get();
if ($patients->isEmpty()) {
return ['value' => 'No Result Found', 'id' => ''];
}
return $patients->map(function ($patient) {
return [
'id' => $patient->id,
'value' => $patient->patient_name,
];
});
}
And this is Route
Route::get('autocomplete',array('as'=>'autocomplete','uses'=>'BookingController#index'));
Route::get('searchajax',array('as'=>'searchajax','uses'=>'BookingController#autoComplete'));
Javascript code is
<script >
$(document).ready(function() {
src = "{{ route('searchajax') }}";
$("#search_text").autocomplete({
source: function(request, response) {
$.ajax({
url: src,
dataType: "json",
data: {
term : request.term
},
success: function(data) {
response(data);
}
});
},
minLength: 3,
});
});
</script>
when i type any patient name in search box i received a message No Result Found
this is the validator in booking controller :
public function store(Request $request)
{
//Validate Data
$this->validate($request, [
'patient_id'=> 'required|integer',
'booking_date'=> 'required|max:255',
'tybe'=> 'required',
'value'=>'required',
'doctor_name',
'patient_history',
'pharma',
'complaint',
'diagnosis',
'recomind',
'prescription',
'notes',
'document',
'by',
]);
//Insert Data to Database
$booking = new Booking;
$booking->patient_id = $request->patient_id;
$booking->booking_date = $request->booking_date;
$booking->tybe = $request->tybe;
$booking->value = $request->value;
$booking->doctor_name = $request->doctor_name;
$booking->patient_history = $request->patient_history;
$booking->pharma = $request->pharma;
$booking->complaint = $request->complaint;
$booking->diagnosis = $request->diagnosis;
$booking->recomind = $request->recomind;
$booking->prescription = $request->prescription;
$booking->notes = $request->notes;
$booking->document = $request->document;
$booking->by = $request->by;
$booking->save();
//to save multi selection Tags ,dont foget to add [] after -> tags in create post page then write this code here
//$post->tags()->sync($request->tags, false);
//Show Flash Message
Session::flash('success','تم حفظ البياانات');
//Redirect to another Page
return redirect()->route('booking.index');
}

SQL's syntax for matching with LIKE operator is:
WHERE `column` LIKE '%needle%'
Your code, on the other hand, produces the following:
WHERE `column` LIKE '&needle&'
Which is virtually the same as if you had typed:
WHERE `column` = '&needle&'
So what you need to do is to replace & with % in the following line:
->where('patient_name', 'like', "&{$request->get('term')}&")
