DiscountSpaceVar

Specify one or more CGI variables to check for discount space switch requests.

Synopsis

The default CGI variable name is "mv_discount_space".

Scope

This directive is only available for use in the local (catalog.cfg) configuration file.  It will not affect any other website in any way.  This directive will not work in the global (interchange.cfg) configuration file. 

Availability This directive was introduced in version 5.4.0, and is therefore not available for use with any earlier Interchange version.

Description

The DiscountSpaceVar directive can be used to define a list of CGI variable names that may be used to select the current discount namespace.

When a page is requested, the named variable(s) will be checked, for in the declared order.  If one of the declared variables has a value then the value given will be used as the name of a discount namespace to which the current session should switch.

If this directive is not specified then a default value of "mv_discount_space" will be used.

Although that default will most likely suffice for most purposes, this directive provides the facility to tie the name of the discount namespace to another variable.  For instance, you might find it convenient to tie the discount namespace name to the "mv_cartname" variable, which you could do using the following directives:

Note The discount namespace facility must be switched on, using the DiscountSpacesOn directive, before this directive will have any effect on Interchange's discount mechanism.
