更新另一个表上的特定表字段

Question

I need to update specific one id / row on a separate field on another table. how is the logic to that? so far i have this pseudo code sql query.

table name : settings

current table : aircrafts

UPDATE settings SET description id = 4

i need to update id 4 on my database in database settings

how can i integrate this code into laravel syntax?

assuming i have this controller

    public function editAirReg(Request $request, $id)
{

    $descr = $request->input('descr_id');
    DB::update('update settings set description = ,'$descr', where id = 4',[$name,$id]);
    return redirect('/admin/aircrafts')->with('success', 'Settings Updated');
}

and also this view

 {!! Form::open(['action' => 'Admin\AircraftsController@getdata', 'method' => 'POST']) !!}


   <input type="hidden" class="form-control" name="settings" value="{{$aircraft->air_line}}">


 {{Form::submit('BIND', ['class'=>'btn btn-primary btn-block btn-lg', 'name'=>'submit'])}}

 {!! Form::close() !!}

First of all, getData() doesn't make sense if you're updating something in mysql. It should be called store() or save or whatever you want to call so that the function name is appropriate.

Let's change the form so that it can pass the id to the controller.

{ Form::open(array('action' => 'Admin\AircraftsController@getdata', $id)) }}
    {{ Form::hidden('settings', $aircraft->air_line) }}
    {{ Form::submit('Submit', array('class' => 'btn btn-primary')) }}
{{ Form::close() }}

What I did is that change your input to the laravel syntax. Also make sure you pass the id from form to controller. take a look at my example. look where I put $id field.

Now in the controller, this is what you do.

$setting = Setting::findOrFail($id); // you must have a model or you can use DB facade
$setting->description = $request->settings; //name that you called it in form
$setting->save();
