Adding variables to the page template

[Ruud]

I wanted to add a single variable to the page object and make it available to the templates. However since the Template object is declared as protected I cannot add the variable in the GeneratePage hook.

The hook is implemented in PageRegular.php line 82: $GLOBALS['TL_HOOKS']['generatePage']

I tried:

class Subtitle
{
	public function onGeneratePage(Database_Result $objPage, Database_Result $objLayout, PageRegular $objPageRegular)
	{
		$objPageRegular->Template->subTitle = $objPage->subTitle;
	}
}

but that generates the errormessage:
Fatal error: Cannot access protected property PageRegular::$Template in C:\xampp\htdocs\domainname.com\system\modules\subt itle\Subtitle.php on line 7 (that is inside the function).

Is there another method to get what I want?

In the meantime I edited the core to just include that one line of the function; problem diverted. I dislike the protected and private statements...

I've run into this before. Try:

<?php global $objPage; echo $objPage->subtitle; ?>

in your fe_ template. It's quick and dirty...

Great! Well, dirty but functional.

Have you placed a ticket for this (feature request)? I'd like to know if this might be changed. Otherwise I'll request it and see how far it gets....

Forgive my n00biness...I'm learning...

But what if your Subtitle class extended Template? Could you access protected properties and methods then?

[winanscreative]

Derp. Yeah, good call, Medianomaly. I would actually just make it extend Frontend and it should then work fine. :D

[Medianomaly]

Ah -- cool. Thanks for the info.

This seems like it would be a REALLY valuable piece of info. Perhaps something for the factory?

[Ruud]

Yep, this indeed works as suggested!

One little thing though; I've never used the protected visibility myself because I'm not sure what the advantage is. Can someone show me an example when this is beneficial? (The advantage of a private visibility I can see from the point of view of whoever builds the class)
