Sending confirmation email

To send a confirmation email via additional processing you can use the script below.

It sends a confirmation email with data collected with the webform module

This assumes you have components in the webform called first_name, last_name, telephone and quantity

The names of the components are taken form the field "Field Key" in the fieldset "advanced settings" of the component

The whole php script including the php tags goes into the "additional processing" field in the fieldset "webform advanced setting" of the webform
Alternatively the script can placed in a php file on the server and called from the "additional processing" using the php include function

for Drupal 6
