Magento – Observer event on frontend home page load

event-observermagento-1.9

Is there any observer event on frontend home page load?

On my custom module, I want to display a notice message on home page if certain conditions are met. Can I do this using event-observer?

Add the following in the extension's config.xml

        <events>
        <controller_action_layout_load_before>
            <observers>
                <abandonedcart_observer>
                    <type>singleton</type>
                    <class>abandonedcart/observer</class>
                    <method>showCouponCodeWhenLoad</method>
                </abandonedcart_observer>
            </observers>
        </controller_action_layout_load_before>
    </events>

And here is the code to go in showCouponCodeWhenLoad() function in Observer.php

    $routeName = Mage::app()->getRequest()->getRouteName();
    $identifier = Mage::getSingleton('cms/page')->getIdentifier();

    if($routeName == 'cms' && $identifier == 'home') {
         // do something
    }

Hope this helps to someone!

Magento – Event on First Load

To my understanding controller_front_init_before is not the best way for setting a cookie as you can miss some redirects and also you have a minimal data in your disposal.

I would recommend using controller_front_send_response_before as the last event triggered before output is sent to browser.

Programmatically Set and Unset Event Triggering for Custom Module

This is not possible - the event will be fired each time for every module including yours. You can only programmatically deactivate the event observer completely, but this is not what you are after.

So the thing you would normally do is to directly check in your observer method if the cookie is set and if it is not set, return instantly:

public function myObserverMethod($observer)
{
    if (<cookie_not_set>) {
        return;
    }
    // do whatever you need to do
}

I understand your point that you do not want to do it like that, because the event is fired so often. The only solution I see here is that you could potentially use a more specific event which is not fired that often like controller_action_predispatch_cms or controller_action_predispatch_cms_index_index. Have a look at the event dispatching code here in order to find a suitable event.
