Question

I would like to choose how many views a post must have to be on my “Top Post” widget. To do that, in with my controller i’ve

public function menu() {
    return $this->Post->find('all', array(
                'limit' => 5,
                'order' => array('Post.id' => 'desc'),
                'conditions' => array('Post.hits >= 100'
                 )));
}

and it’s works perfectly.
Now I wand to change my number (100) by a

Configure::read('top_views');

But i don’t know how to do :/ is there someone who can please help me with this?

Answer 1

Change your menu method to take a parameter with a default value, update the conditions array.

public function menu($hits = 100) {
    return $this->Post->find('all', array(
                'limit' => 5,
                'order' => array('Post.id' => 'desc'),
                'conditions' => array('Post.hits >=' => $hits) // here
                 ));
}

then you can call it and pass in any value you like:

$this->set('top_posts', $this->Post->menu(Configure::read('top_views'));
$more_than_500_hits = $this->Post->menu(500);

This assumes your menu method is in your Post controller, adjust as needed for your own app. Typically this sort of thing should be in the model.
