Add hook only on admin / client

[Eduardo G.]

Hi all.

 

I'm hooking "InvoiceCreationPreEmail" event to add some info to the just created invoice before sending to the client. But I do want this hook when I manually create an invoice from admin.

Inside admin, I can't use "InvoiceCreationPreEmail" on manual invoices as it's not called, so I must use "InvoiceCreated"

 

As both calls will be in the same hook, do you have any idea on how to get a hook executed only in admin or only in client zone?

 

Thanks!
