	}
	/**
	 * Here you can substitute your field name
	 * with a numeric value instead of 'price'

	$price = $request['price'] ?? 1;
	
	/**
	 * More methods here...

I have a custom hook called check_email in JetFormBuilder. This hook checks whether an email exists in the database.

Expected Behavior:
If the email exists, the hook should return true (or "approved"), allowing the form to proceed with the next action.

If the email does not exist, the hook should return false (or "rejected"), preventing further actions from executing.

Issue:
I am unsure how to make JetFormBuilder process actions conditionally based on my hook’s return value. How can I return "approve" or "reject" and use this result to control form execution?

Any guidance would be appreciated!
