server then sends the page to the browser for display. A ColdFusion script, or
template, essentially is a standard HTML file that includes extra tags written
in ColdFusion's server-side markup language, CFML (ColdFusion Markup
Language). CFML tags are case-insensitive, begin with the letters cf, and
direct ColdFusion to process either a calculation or a query. The tags also can
identify a data source and describe how to manipulate or display information
in that data source.
Understanding ColdFusion Tags
The following table describes the ColdFusion tags and the actions that the
ColdFusion Server takes on reading the tags in the sample application:
Tag
cf***
cfoutput
cfset
To build your own Autodesk MapGuide LiteView application, you can
modify the ColdFusion templates that are part of the sample application. The
templates encode the map and feature_info requests to Autodesk MapGuide
LiteView. The following excerpt from map.cfm encodes the map request, for
example:
<cfset maprequest =
"http://" & server & "/servlet/MapGuideLiteView?
REQUEST = MAP &
FORMAT = PNG &
HEIGHT = " & height &
"&WIDTH = " & width &
"&LAYERS = " & mapName &
"&BBOX = " & bbox>
Note The server variable must include the web-server name and context path.
For a default Autodesk MapGuide LiteView installation, server is "local-
host:8080/liteview6.5", for example. For general information about request syn-
tax, see "Formatting a map Request" on page 11.
The templates also control the appearance, toolbar functions, and other
aspects of the application.
ColdFusion Server Action
Processes the script that is embedded in the page into HTML.
Inserts the value enclosed by the tag's begin and end elements
in the map request. For example:
<cfoutput>#variable#</cfoutput>
Sets the bounding-box parameter of the map request.
