$Web_Form_Name retrieves the name of a field on a form.
Syntax
<section begin="syntax" /> %RC = $Web_Form_Name( field_number ) <section end="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.
* Get the number of form fields. %x = $Web_Num_Form * Load the field names into an array. For %y From 1 TO %x %field(%y) = $Web_Form_Name(%y) End For
