How to record several laravel php records

In your form all the inputs that have the $reg->IdCursoPro g, $reg->IdRegistro and the select , are called equal, that is, idCursoProg , IdRegistro and support . This means that the server only reaches the last values of each of them (even if they are a hundred times).

To solve this you have to give an index to each of the elements: idCursoProg becomes idCursoProg[] ; IdRegistro becomes IdRegistro[] ; asistencia becomes asistencia[] .

The server will reach you:

En $request->get('idCursoProg')
    //Entiendo que el curso es el mismo para todos y le pongo un id=2
          [
            0 => "2"
            1 => "2"
            2 => "2"
            3 => "2"
            4 => "2"
          ]
En $request->get('IdRegistro')
    //Entiendo que cada alumno tiene un id y los asigno del 1 al 5
          [
            0 => "1"
            1 => "2"
            2 => "3"
            3 => "4"
            4 => "5"
          ]
En $request->get('asistencia')
          [
            0 => "A"
            1 => "T"
            2 => "A"
            3 => "F"
            4 => "A"
          ]

And in the Controller you will have to deal with each of the elements:

public function store(AlumnoFormRequest $request)
    {
        foreach ($request->get('asistencia') as $key => $value) {
            $asistencia = new Asistencia;
            $asistencia->sesion = $request->get('sesion');
            $asistencia->fecha = $request->get('fecha');
            $asistencia->asistencia = $value;
            $asistencia->idCursoProg = $request->get('idCursoProg')[$key];
            $asistencia->IdRegistro = $request->get('IdRegistro')[$key];
            $asistencia->save();
        }

        return Redirect::to('docente/asistencia');
    }
