Laravel - Does not take the table column

I'm in a dilemma in Laravel that I can not solve, and I've tried a lot of things and now I've stuck here: What I want is to give% of a column value of my table by echo .

Code no input :

public function retorna_curso()
{
    $id_curso = Input::get('id_curso');
    $cursos = DB::table('cursos')->get();
    $select = DB::table('cursos')->where('id_curso', '=', $id_curso)->get();
    return view('editar.update_curso')
            ->with('select', $select)
            ->with('cursos', $cursos);
}

Code in html :

<form action="/updt_curso" method="post"> 
 <div class="form-group col-md-12">
    <?php              
       if(isset($select))
       {
            echo' <div class="form-group col-md-12">
            <label for="edt_nome">Editar nome do curso:</label>
                <input type="text" 
                       class="form-control" 
                       name="input_nomeCurso" 
                       value="'.$select['nome'].'" 
                       id="nomeCurso">';                    
            echo'
            </div>
            <div class="form-group col-md-4">
                <input type="submit" 
                       value="Atualizar" 
                       class="form-control btn btn-primary">
            </div>';
        }                   
    ?>
 </div> 
</form>

It enters Controller , but gives an exception saying that the View property does not exist in if nome that it sends back to page.

• What could I do to solve this problem?
