CakePHP $this->set() don't works in Pages Controller

I am developing with CakePHP and this is my Page Controller:

<?php
class PagesController extends AppController
{
    var $name = 'Pages';
    var $helpers = array('Html', 'Session');
    var $uses = array();

    function display()
    {
        $path = func_get_args();

        $count = count($path);
        if (!$count) {
            $this->redirect('/');
        }
        $page = $subpage = $title_for_layout = null;

        if (!empty($path[0])) {
            $page = $path[0];
        }
        if (!empty($path[1])) {
            $subpage = $path[1];
        }
        if (!empty($path[$count - 1])) {
            $title_for_layout = Inflector::humanize($path[$count - 1]);
        }
        $this->set(compact('page', 'subpage', 'title_for_layout'));
        $this->render(implode('/', $path));

        $this->loadModel('Curso', 2);

        $select = $this->Curso->query("SELECT * FROM cursos ORDER BY `cursos`.`created` D开发者_StackOverflow中文版ESC  LIMIT 2;");
        $this->set('cursos', $select);
        //$this->set($select);

    }
}

But $this->set('cursos', $select); don't works, this is the error:

Notice (8): Undefined variable: cursos[APP/views/pages/home.ctp, line 36].

Anyone can help me?

That's because you're setting it after the $this->render() call. The render call is when the view gets loaded and executed.

Both method worked for me, i have already used.

First Method solution for: (Because the render call is before your set statement)

<?php
class PagesController extends AppController
{
    var $name = 'Pages';
    var $helpers = array('Html', 'Session');
    var $uses = array();

    function display()
    {
        $this->loadModel('Curso', 2);

        $select = $this->Curso->query("SELECT * FROM cursos ORDER BY `cursos`.`created` DESC  LIMIT 2;");
        $this->set('cursos', $select);

        //Now put your rest of code

    }
}
?>

Second Method

<?php
class PagesController extends AppController
{
    var $name = 'Pages';
    var $helpers = array('Html', 'Session');
    var $uses = array();

    function display()
    {

        //put your  code

        $this->loadModel('Curso', 2);

        $select = $this->Curso->query("SELECT * FROM cursos ORDER BY `cursos`.`created` DESC  LIMIT 2;");
        $this->set('cursos', $select);

        try {
            $this->render(implode('/', $path));
        }
        catch (MissingViewException $e) {
            if (Configure::read('debug')) {
                throw $e;
            }
            throw new NotFoundException();
        }


    }
}
?>
