Scenario:

You have a module page that can be accessed like

www.yoursite.com/module/controller/action/id/10

And you want to unset header and footer based on id parameter, for example you don’t want header and footer appear when id is 10.

Wrong way to go:

 $page = (int) Mage::app()->getRequest()->getParam('id'); if($page == '12') { $this->getLayout()->unsetBlock('header'); $this->getLayout()->unsetBlock('footer'); } 

But you can’t unset header footer like above code.

Solution creating custom layout handle:

Fortunately, Magento’s layout engine is flexible enough to provide a way to define our own layout handles and call them explicitly through custom extensions. It’s easy to update unique page layouts by utilizing Magento’s built in ability to insert additional layout handles using an Observer. Let’s see how to create our own layout handles.

1. Create a new observer Observer.php in models directory of your module to assign a new handle as shown below

    Class Namespace_Modulename_Model_Observer extends Mage_Core_Model_Abstract { public function addAttributeSetHandle(Varien_Event_Observer $observer) { $page = (int) Mage::app()->getRequest()->getParam('id'); $handle = sprintf('modulename_controller_action_id_%s', $page); $update = $observer->getEvent()->getLayout()->getUpdate(); $update->addHandle($handle); } } 

2. Enable the new observer in module’s config.xml

    <frontend> <events> <controller_action_layout_load_before> <observers> <attributesethandle> <class>Namespace_Modulename_Model_Observer</class> <method>addAttributeSetHandle</method> </attributesethandle> </observers> </controller_action_layout_load_before> </events> </frontend> 

   The event controller_action_layout_load_before will attempt to run addCustomHandles function in the Oberserver every time the controller action is called.

3. And lastly change the layout for the handle modulename_controller_action_id_12 in modules layout xml.

    <modulename_controller_action_id_12> <remove name="header"/> <remove name="footer"/> <reference name="root"> <action method="setTemplate"> <template>page/1column.phtml</template> </action> </reference> </modulename_controller_action_id_12>
