Undefined Variable in blade view - php

Question

I have this error in a form where i use a foreach in a select option. I can't find where the error is.
Undefined variable: types (View: /var/www/laravel/resources/views/clases/create.blade.php)
Form:
...
<div class="form-group{{ $errors->has('types') ? ' has-error' : '' }}">
<label class="col-md-2 control-label" for="selectbasic">Doy clases de<em>*</em></label>
<div class="col-md-6">
<select id="type" name="types[]" value="" class="selectpicker form-control show-tick" data-live-search="true" multiple="multiple" multiple title="Seleccionar una o varias opciones" data-size="6" data-max-options="8" data-selected-text-format="count > 3">
#foreach($types as $tp)
<option value="{{$tp->id}}" {{in_array($tp->id, old("types") ?: []) ? "selected": ""}}>{{$tp->type}}</option>
#endforeach
</select>
</div>
#if ($errors->has('types'))
<span class="help-block">
<strong>{{ $errors->first('type') }}</strong>
</span>
#endif
</div>

]);
$clase = new Clase;
...
$clase->types()->attach($request->types);
$clase->save();
}
model 'Clase':
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Database\Eloquent\Builder;
use App\Traits\DatesTranslator;
use App\SessionHistory;
use Carbon\Carbon;
class Clase extends Model
{
use SoftDeletes, DatesTranslator;
public $dates = ['moderated_at','reported_at','deleted_at'];
protected $fillable = ['content','...','...','types'];
...
public function types(){
return $this->belongsToMany('App\Type');
}
...
}
model 'Type':
namespace App;
use Illuminate\Database\Eloquent\Model;
class Type extends Model
{
public $timestamps = false;
protected $fillabe = ['type'];
public function clases(){
return $this->hasMany('App\Clase');
}
}
Already checked the two models i use in the controller but can't find the error that it seems to be in the foreach ($types as $tp)...
Any help thanks in advance.

Controller
public function create()
{
$userClases = Clase::where('user_id', Auth::user()->id);
return view('clases.create',compact('userClases'));
}
Form:
<div class="col-md-6">
<select id="type" name="types[]" value="" class="selectpicker form-control show-tick" data-live-search="true" multiple="multiple" multiple title="Seleccionar una o varias opciones" data-size="6" data-max-options="8" data-selected-text-format="count > 3">
#foreach($userClases->types as $tp)
<option value="{{$tp->id}}" {{in_array($tp->id, old("types") ?: []) ? "selected": ""}}>{{$tp->type}}</option>
#endforeach
</select>
</div>
