Adding actions to existing hooks

[The50]

Hello,

 

Is it possible to add some functions to already created hooks? As example I need to fire my function before the logout function goes off. There is a hook called actionCustomerLogoutBefore I believe, how could I add my own function to it?

That is the whoel purpose of hooks. Adding functionality during the process.

 

You need to create a module that can be hooked to the hook. A method called "hookActionCustomerLogoutBefore($param)" need to be implemented in your module's class, then you can hook it in "install" or via your admin.

 

I don't know for this specific hook, if it exists and it is coded, I don't see why not.

Yes I have a module and a function named hookActionCustomerLogoutBefore inside of it. I use die() inside that function but it doesn't work, logout still works as normal. Am I missing something?

 

 

EDIT. oh yeah, I had to register the hook in my module. I thought that it's not necessary because the hook was already created.

You need to register on install() OR adding trought "Modules-> Positions" else the application will not call your method in the your module.
