Hi all- quick question. I have a view which outputs titles. I want to constrain the titles with a function I have that limits the characters. I have placed this function in my controller, however, I need to call the function in my view. How do I go about this? I did attempt to use a ViewModel, but to no avail. Any guidance would be greatly appreciated. Jeremy

I would have a library for common functions call it helper.php and placed it \app\classes\ then in the view you could do this:

<?php \Helper::title('title');?>

Exactly ...
or, if you want, call controller function directly from view with :

<?php echo \Controller_Test::excerpt('bla bla bla'); ?>

but Huzzi method is more elegant

Sounds great! Thanks guys. Is the process to call a model function within a controller relatively the same?

Well, the documentation doesn't really cover making a function in the model and then returning it to the controller. For example, let's say I have a function in my model that finds a specific use based upon their ID. In my controller, I would like to pass a variable representing the user number to a function in the model, then return the result of that function in the controller to then send to the view. However, I am not sure how to do this, even after reviewing the documentation. Thanks!

In a model :

<?php

class Model_Test extends Model {
    
    public static function get_user($id)
    {
        $query = \DB::select('username')->from('users')->where('id', '=', $id)->execute();
        return $query->as_array();
    }
    
}

In a controller :

    public function action_test($user_id)
    {
        $user = \Model_Test::get_user($user_id);
        ...
    }

Huzzi

you could do this with one line of code in the controller if you use orm.

public function action_index()&#123;
$user = Model_User::find($id);
}

*Edit*
Assuming you've setup the Model_User
