Thanks for your reply. Im not sure I follow your suggestion? What are you
proposing with the use of a view helper?
Im trying to follow the example from the Zend_Layout documentation that
states:
------------
"As an example, let's say your code first hits FooController::indexAction(),
which renders some content to the default response segment, and then
forwards to NavController::menuAction(), which renders content to the 'nav'
response segment. Finally, you forward to CommentController::fetchAction()
and fetch some comments, but render those to the default response segment as
well (which appends content to that segment). Your view script could then
render each separately:
<body>
<!-- renders /nav/menu -->
<div id="nav"><?= $this->layout()->nav ?></div>
<!-- renders /foo/index + /comment/fetch -->
<div id="content"><?= $this->layout()->content ?></div>
</body>
This feature is particularly useful when used in conjunction with the
ActionStack action helper and plugin, which you can use to setup a stack of
actions through which to loop, and thus create widgetized pages. "
------------
I have this working based on an example here:
http://teethgrinder.co.uk/perm.php?a=Zend-Framework-Menus-Navigation
The problem is that when using a _forward() to another action within the
same controller the init() gets called every forward thus resulting in the
$this->_helper->actionStack('menu', 'navigation') getting called every time.
This means the navigation menuAction gets rendered a number of times when
obviously it only wants to render once...
So ultimately how can I detect if the current controller init() has been
called as the result of a _forward() and thus then not add the menuAction
to the stack...?
Also if there is a better simplified way of doing this i'd be enlightened to
know!
Thanks,
David
