@Eppo: Hm, I just tested it here with the latest CakePHP version, and it works as described in the article. Can you post the relevant code somewhere, for example on http://bin.cakephp.org?

well i tried this, but nothing was showed in the $var_for_layout

When i do a pr($this->value) in afterRender.. its just empty..

When i do a pr($this->value) in valueSet($value) I get the value thats set in the view..

How to do this?

@Webspin: Your model shouldn’t know anything about a view resp. a layout. That means your controller has to get the data from the model and pass those data to the layout.

Is there a way to set a custom layout variable from within the model directly? Or do you have to pass values from the model to the controller, and then have the controller set them to the layout?

@moeffju: No, it is a fine solution for certain scenarios, see also the other comments.

I would just set the generic for_layout var in the AppController’s beforeFilter (to ”), and overwrite them in the specific controllers. Is there any reason that would be a bad idea?

By using @ you’re only supressing the notice on the variable you’re *expecting* so it’s ok.

@Dieter: Yes, I am calling $demo->setValue(‘value’); from my view.

@Felix: Yes, that works. But personally I think it is a bad idea to suppress error messages for errors you can simply avoid.

@felix: thanks for the tip.

In case anyone else was like me and didn’t know what Felix is talking about, check out the documentation on PHP’s site:
