Logic Hook - Firing just once

[leowolff]

Hello, I have implement a logic hook that send an email (based on this sugestion: http://www.redinkdesign.net/node/6) when an event occour.

I have a custom module called services, and I have to inform the responsible when a new service is created and only that. But if I use after_save logic hook it will send an email not only when a new service is created, but everytime its modified, and I dont want that.

Does anyone have an idea how to send only 1 email in this case?

I had a similar situation a while back with a customization I was making for a client.

What I ended up doing was create a custom field where I could store a flag that indicated whether or not the e-mail had been sent.

For example, you could use an integer field whose value is set to 0 by default. When your logic hook triggers, only send it if it is set to 0 and then use the logic hook to update it to 1 or some other value as part of the logic that sends the e-mail. Thus the next time around it shouldn't send it out again.

That's a nice, elegant solution. If the process were to fail sending the email for whatever reason then the user could always go back in and hit save to try to send it again since the send email flag would still be 0. Much better then checking to see if it is a new or existing record on each save.
