Is there a comprehensive list of observer events? - magento

Question

Is there a comprehensive list of all events that can be listened for?
If this list doesn't exist, what's the best method to debug to obtain all events?

Answer 1

You'll never find a complete list. But if you go to app/Mage.php you can put in some debug code inside of the function "dispatchEvent()" and log all of the events as you go.
$params = array();
foreach (array_keys($data) as $key) {
if (is_object($data[$key])) {
$params[] = $key.' ('.get_class($data[$key]).')';
} else {
$params[] = $key.' ('.gettype($data[$key]).')';
}
}
Mage::log('event_name:'.$name.',event_passed_keys:'.implode('|',$params),null,'events.log',true);
Then using some excel wizardry you can parse those out into a list of all of the event names and parameters being passed to it.
The problem with many of the compiled lists or even doing the grep as shown above is that many of the events are dynamically created. Which lets you discern what events there are that aren't listed.
Make sure to comment out that debug code or the events.log file will become huge after just a short time.

Take a look at a list of events #

Customize Magento using Event/Observer
or
To log all the event for a specific page in your dev environment you could add Mage::log($eventName);
in /app/code/core/Mage/Core/Model/App.php
public function dispatchEvent($eventName, $args){
Mage::log($eventName);
....
or
grep -r Mage::dispatchEvent /path/to/your/Magento/* > events.txt

Answer 3

As an exercise I wrote a Bash script to generate rough list of events (it actually acts as a wrapper to grep with a few switches to provide context and available params).
I've used this script to generate events lists for default Magento installations for versions 1.3.3.0 to 1.8.0.0 version and the code is available at GitHub:
https://github.com/Marko-M/magento-events-list/
Lists of events are available here:
https://github.com/Marko-M/magento-events-list/tree/master/magento-outofthebox
and a follow up article on my blog here:
http://www.techytalk.info/bash-script-to-generate-list-of-events-for-magento-installation/
Be aware that these lists can never be complete due to many event names being generated dynamically.
As you probably have extensions on your project and they dispatch their own events, it's even better to generate this list manually trough grep or using my script.
Cheers!

Answer 4

a general mean is to set an observer for any specific event you are interesting in
see https://magento.stackexchange.com/questions/314/how-to-know-the-magento-event-that-we-want-to-hook
in the module Logevent, the config.xml
0.1
Maticode_Logevent_Model
<controller_action_predispatch>
<observers>
<Logevent>
<type>singleton</type>
<class>Logevent/observer</class>
<method>controller_action_predispatch</method>
</Logevent>
</observers>
</controller_action_predispatch>
and the Model/observer.php
<?php
class Maticode_Logevent_Model_Observer {
public function controller_action_predispatch($observer) {
Mage::log ( $observer->getEvent ()->getControllerAction ()->getFullActionName (),null, 'eventlog.log' );
}
}
This way , in the
var/log/eventlog.log file
u can visualize a possible hook on any tested actions (click on a button and check your log )
