[ZF] Adding ("current/active/highlight" and/or other) class to menu item

So I had this menu that finally decided to generate correctly from an XML file, cool. Now I thought of the two following thigs:

1. Show which tab is active depending on the page
2. Add icons to the tabs

... and I wanted to implement this in the bootstrap file to make later changes easier.

1. Adding CSS class to current menu element
For the first item, nothing better than to head over to Stack Overflow, as usual. As you can see in there, all you need is:
$uri = $this->_request->getPathInfo();
$active_nav = $this->view->navigation()->findByUri($uri);
$active_nav->active = true;
$active_nav->setClass("active");

However, this won't work in the bootstrap because the request parameters aren't available yet. If you have a menu generating like this, it's very likely you already have a method for generating it in your bootstrap file (e.g.: _initNavigation()). To access the request parameters and find the path info, add this beforehand:
$this->bootstrap('frontController');
$front = $this->getResource('frontController');
$front->setRequest(new Zend_Controller_Request_Http());

Then, just arrange the previous code to find the correct data:
$uri = $front->getRequest()->getPathInfo();

And there we go, the "active" class will be added to whichever tab you are on.

But wait, what if I wanted to add custom icons for each tab?

2. Adding icons to menu tabs
So you've tried adding the image to the label, like so:
<label><img src="/image/nav-1.png" alt="nav-1" />User</label>
... but it doesn't work.

The trick is rather easy, just add some stuff in your CSS file as a class, and add the following node to your XML file (I guess you could easily adapt it if you're loading data from an array):
<class>nav-1</class>

Only there's a slight problem: if you are on the active tab, the bootstrap will override the class and set it to "active".

I've actually found the solution on the first try (nice guess, I admit). In the bootstrap (see code above), just get the tab's current class and add "active" to it:
$current_class = $active_nav->getClass() . ' ';
$active_nav->setClass($current_class . 'active');

That's all there is to it, you can now have a dynamic and beautiful menu!

[ZF] Hiding navigation elements

If you're building an XML file to create a menu/breadcrumb/sitemap and wish to hide elements from, let's say, the menu, here is what you can do:
Add <visible>0</visible> to your node

You can then use the usual <?php echo $this->navigation()->menu(); ?> to generate your menu.

Also note that making a node invisible will make all its children invisible as well. Duh.

Finally.

So I've been thinking about creating a blog for a long time now, to share anything I can find that seems interesting and out of the usual programming routine. If ever I discover anything, be it myself or from another source, I'll try to remember to share it with you!
