Implementing combo boxes

[Barend Köbben]

Hi,
 
I dont know about implementing them "In" Mapserver. I think you'd implement them on a Dynamic Webpage and use the combo-list choices to feed to MapServer. Below's a quick snippet how I would do that using JSP. Exchange with your script language of choice...
 
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String mySHPpath = request.getRealPath("/") + "SHP"; //get path on server that points to SHP directory
int myFilesNum; 
String[] MyFilesList; 
File myDir = new File(mySHPpath);
if (myDir == null) {
 out.println("<br/>ERROR: SHP directory not found at " + mySHPpath + " <br/>");
} else {
 MyFilesList = myDir.list();
if (MyFilesList == null) {
 out.println("<br/>ERROR: no SHP files found in directory " + mySHPpath + " <br/>");
} else {
 myFilesNum = MyFilesList.length;
%>
<select name="fileBox">
<% for (int i = 0; i < myFilesNum; i++) {%>
 <option value="<%=MyFilesList[i]%>"><%=MyFilesList[i]%></option>
<%}%>
</select>

Does anyone have experiencing implementing combo boxes in Mapserver.  I want the combo boxes to list shapefiles that the user can add to the display and legend.  I just need a broad approach or any tips.

 

Thanks
