Pass data from a query to a view - mysql

Question

The problem I have is that I do not know how I can use the data of a query in a view if someone can give me a serious idea, the form I use is this but it gives me an error:
My Controller:
public function edit($id){
$datosProfesor = DB::table('profesor')->where('id', $id)->get();
$institucionDB = DB::table('institucion')->get();
$datos = array('datosProfesor' => $datosProfesor, 'institucionDB' => $institucionDB);
return view('profesorView/editarProfesor', $datos);
}
My view:
<div class="form-group">
<h4>Nombre</h4>
<input type="text" name="nombre_profesor" id="nombre_profesor" class="form-control" placeholder= 'Nombre' value="{{$datosProfesor['id']}}">
</div>
The error that appears to me is this:
Undefined index: id (View: /var/www/html/Konecte/resources/views/profesorView/editarProfesor.blade.php)

Answer 1

The get() method returns an Illuminate\Support\Collection containing the results where each result is an instance of the PHP StdClass object. You may access each column's value by accessing the column as a property of the object:
foreach ($datosProfesor as $profesor) {
echo $profesor->id;
}
If you want to get a single result then you can use find() method as:
$datosProfesor = DB::table('profesor')->find($id);
which is a short form of:
$datosProfesor = DB::table('profesor')->where('id', $id)->first();
Just one more tip for you that you can use PHP's compact() method for creating array containing variables and their values. So that you can get rid of line
$datos = array('datosProfesor' => $datosProfesor, 'institucionDB' => $institucionDB);
Your final code will look as:
public function edit($id){
$datosProfesor = DB::table('profesor')->find($id);
$institucionDB = DB::table('institucion')->get();
return view('profesorView/editarProfesor', compact('datosProfesor', 'institucionDB'));
}
