This is actually the config for Pyrus... should just be $config = new \PEAR2\Pyrus\Config(); $config->preferred_state = 'alpha'; or some such thing. I would stick it in the config.inc.php. I figured there were some other places I did something similar, but maybe not. > I'm also making the menu into a savant template as you suggested.

In that sense, you could make a template: <li><?php echo $context; ?></li>, but it's probably easiest to just do $menu = new PEAR2Web\Menu(); $savant->render($menu); which will include a PEAR2Web/Menu.tpl.php template file, with your $menu object as $context. > I tried passing the array as an ArrayObject and it fails in a different > way.

Yeah, there are some tricky things that happen variable escaping is turned on and you pass a traversable object as the context. The array access methods should be added in. > I have a couple of other Savant questions as well: > > 1.

Use ->getRaw('membervarname'); or getRawObject(); to get the raw vars. > 2. Is there a method I can call to tidy-indent a block of output?
