Laravel model binding for select dropdown - php

Question

I want the select dropdown value to be selected in my edit form.
In my controller
public function edit($id)
{
$vedit = DB::table('vehicles')->where('id', $id)->first();
$cartype= DB::table('car_category')->pluck('cartype');
return view('vehicles.edit', compact('vedit','cartype'));
}
In view
{{ Form::label('Vehicle Type', 'Vehicle Type') }}
<select name="vehicle_type" class="form-control">
#foreach($cartype as $cartypes)
<option value="{{ $cartypes}}">{{ $cartypes}}</option>
#endforeach
</select>
How can I achieve this?

Answer 1

You can add selected attribute if it's the choosen one like this :
{{ Form::label('Vehicle Type', 'Vehicle Type') }}
<select name="vehicle_type" class="form-control">
#foreach($cartype as $cartypes)
<option value="{{ $cartypes}}" {{ $cartypes == $vedit->vehicle_type ? 'selected' : ''}}>{{ $cartypes}}</option>
#endforeach
</select>

Answer 2

What version of Laravel are you using ? Looks like you're using Laravel Collective Form facade.
In that case, this should work fine:
{!! Form::label('Vehicle Type', 'Vehicle Type') !!}
{!! Form::select('vehicle_type', $cartype, $vedit->vehicle_type ?: old('vehicle_type), ['class' => 'form-control']) !!}
Assuming $vedit->vehicle_type is your previously stored vehicle type. So it will pre-select that when editing. In case of creating new, old('vehicle_type') should persist the previously selected value on failed validations.

Answer 3

By calling pluck() an array of values is already returned for the car types.
So just use it like this natively with Laravel Collective:
{!! Form::label('Vehicle Type', 'Vehicle Type') !!}
{!! Form::select('vehicle_type', $cartype, null, ['class' => 'form-control']) !!}
Note, I have also changed your double curly braces. The double curly braces escape the output - given the Form facade returns HTML code, you want this to be unescaped.

Edit show currently selected value and old value if form fails validation:
{!! Form::label('Vehicle Type', 'Vehicle Type') !!}
{!! Form::select('vehicle_type', $cartype, old('vehicle_type', $vedit->vehicle_type), ['class' => 'form-control']) !!}
