Field: env_report

Description: Allows you to have Environment variables included in the e-mail message you receive after a user has filled out your form. Useful if you wish to know what browser they were using, what domain they were coming from or any other attributes associated with environment variables. The following is a short list of valid environment variables that might be useful:
REMOTE_HOST - Sends the hostname making the request.
REMOTE_ADDR - Sends the IP address of the remote host making the request.
REMOTE_USER - If server supports authentication and script is protected, this is the username they have authenticated as. *This is not usually set.*
HTTP_USER_AGENT - The browser the client is using to send the request.

There are others, but these are a few of the most useful. For more information on environment variables, see:

The CGI Resource Index: Documentation: environment Variables

Syntax: If you wanted to find the remote host and browser sending the request, you would put the following into your form:
