Usage Notes
ProfileHasLastMarkerWithKey determines whether the last profile marker added to the profile with a particular key has the additional parameters you specify. These additional parameters can be specific values for the value, data, or other marker properties you specify. If the last marker with a particular key matches the other parameters you specify, the true open parameter is rendered and the marker is made available to the page through the marker output parameter.
For more information on working with marked profiles, see the Using Marked Profiles section in the Using Profile Markers chapter of the Personalization Programming Guide.
Example
The following example shows how to determine if the last profile marker added to the current profile with a key of partner has a value of travel site A. Users who have such a marker see a message informing them about airfare discounts.
<dsp:droplet name="/atg/markers/userprofiling/droplet/ProfileHasLastMarkerWithKeyDroplet"> <dsp:param name="key" value="partner"/> <dsp:param name="value" value="travelSiteA"/> <dsp:param name="data" bean="ProfileHasMarkerWithKeyDroplet.ANY_VALUE"/> <dsp:oparam name="true"> When you book your hotel room with us, you'll receive a discount on airfare if you book your flight with travel site A! </dsp:oparam> </dsp:droplet>
