I am looking to create some new functionality to Magento. I am going to be looking to the url and grabbing a paramete开发者_运维百科r. The issue is, this can be on any page. So I can't just extend a Catalog or Checkout Module.
I thought about extending the session classes but I wasn't sure it really fit. Basically I want to grab a parameter from the url and from there add some functionality if it is set or not. I don't think a class will get auto loaded unless it is instantiated somewhere else with a getModel method, am I wrong?
How can you add a module that doesn't have a url path for controller and what not, but doesn't fit extending one of the core modules?
I looked for a generic event but didn't really see one like before_page_load or something
Take a look at the event controller_action_predispatch
in app/code/core/Mage/Core/Controller/Varien/Action.php
. This event should get called on each dispatch and allow you to grab whatever parameters you need.
The event passes the controller as data, so you can do this:
function yourEvent( $event ) {
$controller = $event->getController();
// your processing here
}
Let me know if that doesn't fit the bill. Hope that helps!
Thanks, Joe
