Can we see a bit more code?
So far I've got this to work with manually rendered views.
$view->setHelperPath('/path/to/helper/class');
print $view->render('view.phtml');
This here is the class named FooBar.php within /path/to/helper/class
<?php
class Zend_View_Helper_FooBar extends Zend_View_Helper_Abstract {
public function fooBar()
{
return 'random string this will be the output';
}
}
Within view.pthml
print $this->fooBar();
Outputs
random string this will be the output
