Transferring Variables in Query String
Transferring variables to the query string is often desired when a user inputs some data interactively in a banner, e.g., e-mail address, telephone number, location. This can be achieved by appending ";urlappend=" parameter to a clickTAG. The method of transferring these variables in the query string is described in the example below.
Using ;urlappend= in query string values
var custom = ';urlappend='+'?street='+street+'&country='+country+'&city='+city+'&zip='+zip; window.open(clickTAG + custom, landingpagetarget);
If the clickTAG is, for example, set to http://www.site.com?Destination=, the user gets redirected to http://www.site.com?Destination=London when the banner is clicked.
Note: Variables in the query string cannot be tested in a banner's preview page. All query string variables will be passed on to the final landing page only when the banner is uploaded to campaign in the Adform system and published.
