Laravel 4 - pagination filter reults - filter

Question

Does anybody know why I have an error when I'm using the Laravel pagination after filter results in a View?
It works perfectly in my simple view, but when I filter data using the form I've created for... the same pagination doesn't work!
MY CODE:
Controller:
public function filtro()
{
$keyword = Input::get('keyword');
$asignatura = Input::get('asignatura_id');
$nivel = Input::get('nivel_id');
$actividades = Actividad::where('actividad', 'LIKE', '%'.$keyword.'%');
if($asignatura){
$actividades->where('asignatura_id', $asignatura);
}
if($nivel){
$actividades->where('nivel_id', $nivel);
}
$actividads = $actividades->orderBy('created_at', 'DES')
->paginate(10);
$id_user = Sentry::getUser()->id;
$fichas = Ficha::where('user_id', $id_user)->orderBy('created_at', 'DESC')->get();
$asignatura_clave = Asignatura::where('id', $asignatura)->first();
$asignatura_id = Asignatura::orderBy('nombre', 'asc')->lists('nombre','id');
$nivel_id = Nivel::orderBy('edad', 'asc')->lists('edad','id');
$nivel_clave = Nivel::where('id', $nivel)->first();
$user = User::find($id_user);
// Devuelve todas las actividades que estan relacionadas con alguna ficha.
$actividadEnFicha = Actividad::has('fichas')
->get();
//$asignaturas = Asignatura::all();
// return var_dump($actividadEnFicha);
return View::make('actividads.index')
->with('fichas', $fichas)
->with('user', $user)
->with('palabra_clave', $keyword)
->with('keyword', $keyword)
->with('nivel_id', $nivel_id)
->with('nivel_clave', $nivel_clave)
->with('asignatura_clave', $asignatura_clave)
->with('asignatura_id', $asignatura_id)
->with('actividadEnFicha', $actividadEnFicha)
->with('actividads', $actividads);//->with('asignaturas', $asignaturas);
}
The pagination code in my View:
{{ $actividads->links(); }}
MESSAGE ERROR:
Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException
* #param array $others
* #return void
*
* #throws \Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException
*/
protected function methodNotAllowed(array $others)
{
throw new MethodNotAllowedHttpException($others);
}
EDIT:
I've created these two routes
Route::post('filtro', array('as' => 'filtro', 'uses' => 'ActividadController#filtro')); and Route::get('filtro', array('as' => 'filtro', 'uses' => 'ActividadController#filtro')); , and pagination works.
The problem now is when I change to another page (using pagination) my filters are forgotten and it paginates all my activities angain... :S Any idea why? This is the first time I try it, and probably I'm doing it in a wrong way.
Any idea what's happening?
Thanks!

Answer 1

I have two remarques, the first is that inside the if you should assign the new result. Second is in the orderBy the second parameter should be 'DESC' and not 'DES'. And I think this second error is causing your issue.
if($asignatura){
$actividades = $actividades->where('asignatura_id', $asignatura);
}
if($nivel){
$actividades = $actividades->where('nivel_id', $nivel);
}
$actividads = $actividades->orderBy('created_at', 'DESC')
->paginate(10);
Hope this fixes your problem
Edit
The MethodNotAllowedHttpException is usualy caused by a route not allowing some type of requests. the paginate links sends the page number to the action using GET and I guess you're not allowing GET in your routes for this method.

I've solved my problem with pagination using session.
My problem was that, when I changed the page by pagination, everything was reloaded and my filters were forgotten. So I created a session for every filter and now I can move through my filtered data by pagination.
