CakePHP – link / include JavaScript files in layouts

Create (or modify the) file
app/app_controller.php
add this code

class AppController extends Controller {
var $helpers = array('Html', 'Form', 'Javascript');
}

CakePHP 1.2 allows you to define a reference to a Javascript file which is then added to the head section of the generated code. For this purpose the variable $scripts_for_layout has to be added to the layout:

< ?php echo $scripts_for_layout; ?>

In the view you can now link to the Javascript file with:

$javascript->link('script.js', false);
// OR you can simply use $javascript->link('script.js');
