SitePreferences is a container for custom site-level attributes. The object
corresponds with system object type "SitePreferences". It has no system
attributes and exists only as a place for merchants to define custom
attributes which need to be available for each site.
Logically there is only one SitePreferences instance per site. The instance
is obtained by calling Site.getPreferences()
. Once an
instance of the container is obtained, it is possible to read/write site
preference values by using the usual syntax for
instances. For example:
var sitePrefs : SitePreferences = dw.system.Site.getCurrent().getPreferences();
var mySitePrefValue : String = sitePrefs.getCustom()["mySitePref"];
this class allows access to sensitive security-related data.
Pay special attention to PCI DSS v3. requirements 2, 4, and 12.
Commerce Cloud Digital defines many site-level preferences, relating to
baskets, timezone, locales, customers, etc, which can be managed within the
"Site Preferences" module of the Business Manager, but these preferences are
not accessible through this object. (SourceCodeURLParameterName is the one
exception to this rule.)
