php - Serialization of 'Closure' is not allowed - laravel

Question

I'm trying to create a tuple in my table. The data is from a form or received. My database:

View

@extends('plantilla')
@section('contenido')
<div class="formulario">
{{Form::open(array('url' => 'servicio/create', 'files' => true))}}

    <input type="text" class="form-control"  id="direccion" name="dirrecion" placeholder="Dirección" >
    <input type="text" class="form-control"  id="cliente" name="cliente" placeholder="Nombre Cliente" >
    <input type="time" name='horainicio' id='horainicio' min='time' max='time' >
    {{Form::file('pdf', array('title' => 'Search for a file to add'))}}
    {{Form::select('idtecnico', $tecnico_selector)}}
    {{ Form::submit('Guardar', array('class' => 'btn btn-primary ')) }} 
{{Form::close()}}
    </div>  
    @stop

Route

Route::get('servicio/create', function(){
$tecnicos = Tecnico::all();
    $tecnico_selector = array();
    foreach ($tecnicos as $tecnico) {
        $tecnico_selector[$tecnico->idTecnico] = $tecnico->Nombre;
    }
    return View::make('formservicio', array('tecnico_selector' => $tecnico_selector));
 });
 Route::post('servicio/create', array('uses' => 'ServicioController@doCreate'));

Model

class Servicio extends Eloquent{
protected $table = 'Servicio';
protected $primaryKey = 'idServicio';
protected $fillable = array(
                            'Direccion',
                            'RutaPDF',
                            'Completado'
                            );
public function materialUsado(){
    return $this->hasMany('Material_Usado', 'idMaterial_Usado');
}

public function tecnicos(){
    return $this->belongsToMany('Tecnico', 'Servicio_Tecnico', 'Servicio_idServicio', 'Tecnico_idTecnico');
}
    }

Controller

class ServicioController extends BaseController{
public function doCreate(){
    $rules = array(
                'idtecnico' => 'required',
                'direccion' => 'required',
                'cliente' => 'required'
                );
    $validator = Validator:: make(Input::all(), $rules);

    if($validator->fails()){
        return Redirect::to('servicio/create')
                ->withErros($validator)
                ->withInput();
    }else{
        $input = array(
                'Direccion' => Input::get('direccion'),
                'Cliente' => Input::get('cliente'),
                'Completado' => '0'
                );

        Servicio::create($input);
        /*$servicio = new Servicio;
        $servicio->Direccion = Input::get('direccion');
        $servicio->Cliente = Input::get('cliente');
        $servicio->Completado = '0';
        $servicio->tecnicos->attach($idtecnico);
        $servicio->save();*/

        $path = public_path().'/servicio/'.$servicio->idServicio;
        File::makeDirectory($path, $mode = 0777, true, true); // creamos la carpeta
        $archivoPdf = Input::file('pdf');
        $archivoPdf->move($path, 'servicio');

        /*$servicio->RutaPDF = $path.'/servicio';
        $servicio->save();*/







    }
}
}

When completely changes the form and send it, the following error

how can I fix it?

Answer 1

You have a typo in your controller: ->withErros($validator) - it should be withErrors. The difference is big.

Laravel converts withErros($validator) into with(['erros' => $validator]), which means trying to put the entire validator object into the session. To put things into the session storage, it needs to be serialized first, which is what is causing the error.
