Search and Pagination Laravel 4

Question

I have a problem, I want to use the form to do a search and use pagination. The problem is when I change the page, an error occurs:

No query results for model [Aluno].

My controller

Route::post(
'alunos/busca', 
array(
    'as' => 'alunos.busca', 
    'uses' => 'AlunosController@busca'
)

);

My Controller

public function busca()
{
   $search = Input::get('q');
   $alunos = Aluno::where('curso', $search)->paginate(1);
   return View::make('alunos.index', compact('alunos', 'search'));
}   

My view:

<form method="post" action="{{ URL::to('alunos/busca') }}">
<input class="input-xxlarge" name="q" type="text" placeholder="Search...">
<div class="control-group">
    <div class="controls">
        <input type="submit" class="btn" id="submit" value="Submit" />
    </div>
</div> 
<div class="divPagination">
   {{ $alunos->links() }}
</div>

I need help..

Sorry my English

Answer 1

I think the best solution is the next one:

1. Copy and paste this form wherever you want it:

   {{Form::open(array('url' => 'alunos/busca','method' => 'get'))}}
   {{Form::text('q', null , array('placeholder' => 'Search...','class' => 'input-xxlarge'))}}
   {{Form::submit('SEARCH',array('class' => 'btn','id' => 'submit'))}}
   {{Form::close()}}
   

2. In routes.php :

   Route::get('alunos/busca', function() {
      $search = Input::get('q');
      $alunos = Aluno::where('curso', 'LIKE', '%'.$search.'%')->paginate(15);
      return View::make('alunos.index')
       ->with('alunos', $alunos);
   });
   

3. Now, in your view app/views/alunos/index.blade.php :
   

   @if(!$alunos->isEmpty())
      @foreach($alunos as $aluno)
         {{$aluno->subject}}
      @endforeach
   
    {{$alunos->links()}}
   
   @else
      <h1> No results </h1>
   @endif
   

4. Change it as you wish and enjoy

The problem is when you click on the next page it has no memory of the search param you just entered, essentially $q = null; which will cause the error.
