Folks, I know that MapServer can draw dynamic thematic map(choropleth map) via cgi. I'd like to develope MapServer app via PHP MapScript to realize the dynamic thematic map. But i find that the PHP MapScript interface cannot do this. For instance, i have only one polygon layer about U.S states,and this layer has 50 fields in the dbf or in MySQL,the most important thing is that these attributes values varying everyday. When the user select one of the fields from the droplist component of the MapServer web app in Firefox or ie explorer,then the dynamic thematic map wil be drawn automaticly with the selected fields. What can i do this via PHP MapScript ? I need your help. Thank a lot to you first! Best regards jxRui
