Change / customize subject line in contact form

Hi there,
Please advise me as to the procedure to follow should I require a customized subject line in the contact form.
I have a customer that is looking to provide a standard "Inquiry from website" message in the subject line of the contact form.
Kind regards,
Shane

You'll need to be more specific about what form you're referring to. CB has no control over Joomlas contact form. If you mean CBs email form accessible while viewing a users profile and clicking the link in the Email field or on the menu above their profile then it doesn't have a subject unless the user supplies one.

The contact form I'm referring to is the CB email form accessed via the email link - here's a view of what I'm referring to (please see attachment).

There's no option to set a subject for that. The subject is user supplied. Best I can suggest is trying to override it using CB Auto Actions. The below should work.

Global
Triggers: onBeforeEmailUser
Type: Code
User: Automatic
Access: Everybody
Action
Method: PHP
Code: Parameters
Reference Variables: Variable 6

That should prefix the subject the user supplied with "Inquiry from website: ". For that trigger variable 6 is a reference variable and is the subject so it can be modified. Below are the other variables available to that trigger.
