Syntax

$Web_Form_Name takes a single argument and returns a string or null if the number references a non-existing field.

The only parameter is the number of the form field for which the name is being requested. This parameter must be specified.

$Web_Form_Name is useful when writing generic server applications, when the server does not know what field name exists at a particular location in a POST request.
