The documentation of Mapserver says this:
Variables can be substituted within MapFile parameter values. At this time, cookie and CGI parameter values are supported. This allows MapServer MapFiles to be aware of a user's cookies (good for implementing security), or non-MapServer request parameters (good for integrating with other systems).
Syntax: '%' + variable name + '%'
But the examples are not clear. If I want to pass in a CGI variable, such as [mapx] and [mapy], into a data statement to select from a postGIS database; such as:
CONNECTIONTYPE postgis
CONNECTION "user=auser dbname=mydb host=myserver"
STATUS ON
DATA "counties from states where thislon = %mapx% and thislat = %mapy%"
Does not seem to work. Help?
