Re: [fw-mvc] Registering Helpers with Views

Here's how I imagine this would look like:

// Adding a custom helper

$view = new Zend_View();

$helper = new MyCustomHelper();

$view->addHelper($helper, 'foo');

$view->foo(); // calls MyCustomHelper#foo()

// Overwriting a built-in helper

$myUrlHelper = new MyUrlHelper();

$view->addHelper($myUrlHelper, 'url');

$view->url(); // calls MyUrlHelper#url();

There's always a potential for a BC break when adding new methods to Zend_View_Abstract, but the chances are slim that someone created their own view helper named "AddHelper". Just something to keep in mind when picking the name for the method.

There is not a way to do this currently; it was not a part of the
original design specification.

If you would like to see this in a future version, please put in a
request on the issue tracker, or create a proposal indicating how you
would envision this working.

Thanks!
