Name of isindex or form field
$Web_Name retrieves the name of an isindex or form field in a request.
$Web_Name takes a single argument and returns a string or null if the number references a non-existing field.
Syntax
%rc = $Web_Name( field_number )
Syntax terms
The only parameter is the number of the isindex or form field for which the name is being requested. This parameter must be specified.
Usage notes
- $Web_Name is useful when writing generic server applications, when the server does not know what field name exists at a particular location in an isindex or form request. For example:
* Get the number of isindex or form fields. %x = $Web_Num * Load the field names into an array. For %y From 1 To %x %field(%y) = $Web_Name(%y) End For
- $Web_Name first counts isindex fields and then form fields. $Web_Name can be used instead of $Web_IsIndex_Name and $Web_Form_Name to make it easy to switch between using "method=GET" and "method=POST"
<form>tags and simply to save typing.
