Re: Global data

Global variables in general are the spawn of satan.  However both
constants and using Configure::write('var', $value) are excellent
replacements as they prevent the collisions and spaghetti code that
globals can help create.

Your best bet is to probably set a constant in the bootstrap.php file.

Hey,

You can use the Configure class of cakephp to store your settings in 
configuration files like cake do for storing its 
configurations('config/database.php' , 'config/core.php' etc..).

See the api for the class (located at 'cake/libs/configure.php')for more 
details

regards,
Sudhir

Re: Global data

[mariano.iglesias]

Just use the beforeRender() method at AppControler, which should be the
base of your controllers.

So for example you have app_controller.php on your app/ directory:

class AppController extends Controller {
 function beforeRender() {
  $data = array (
   'message' = 'Hello World!';
  );

  $this-set('data', $data);
 }
}

Then you have your controllers extend AppController. For example, you
can have app/controllers/test_controller.php:

class TestController extends AppController {
 function index() {
  // Do nothing
 }
}

And also

 app/controllers/another_test_controller.php:

class AnotherTestController extends AppController {
 function index() {
  $this-set('extra', 'Extra Message');
 }
}


Then the app/views/test/index.thtml:

And the message is: ?php echo $data['message']; ?

And the app/views/another_test/index.thtml:

And the message is: ?php echo $data['message']; ? with some extra
message: ?php echo $extra; ?

Remember the MVC separation logic. Data should be passed on TO the
view, and the view SHOULD NOT fetch data by itself.

Global data

[Synchro]

Quite often I need to display data that's common to a lot of views -
for example, when dealing with a user that's linked to an organisation,
to display the organisation that the user belongs to on every page they
see. It seems obtuse to have to call $this-User-Find... in every
function in every controller. Outside Cake, I'd usually stick the
organisation in the session to save lookups and provide easy access,
but I've not found a way of accessing a session value from a view
without having to call set() in every function, which is almost as bad.
I suspect there is some simple 'Cakeish' way of sharing data between
views, and across different controllers, but I've not found it as yet.
