[OpenLayers-Users] How do you represent multiple layers

[Arnd Wippermann]

Hi,
 
i would think, it must look 
 
layers:'states_poly,states_line' as one string.

Also I would suggest, because it is a MapServer layer the title should be
OpenLayers Mapserver.


Mit freundlichen Grüssen

Actually that is not a very good idea and bad coding practice.
Your problem was including {layers:'basic'} the word basic is not some
variable relating to type or styule of layers it is an actual layer name in
the example WMS. Instead of "basic" you should have your layer names listed
there. So your code should be:
var loadedMap = new OpenLayers.Layer.MapServer( "OpenLayers WMS",
"http://localhost:8085/cgi-bin/mapserv.exe?
<http://localhost:8085/cgi-bin/mapserv.exe?layer=states_poly&layer=states_li
ne> ",
{map: '/ms4w/apps/app/test.map', mode:'map', format: 'png',
transparent:'false', layers: 'states_poly','states_line'},
{gutter: 15});

 hope that helps

A variation on your theme worked. I put the multiple layers in the URL

this 
http://localhost:8085/cgi-bin/mapserv.exe?map=/ms4w/apps/app/test.map&layer=
states_poly&layer=states_line&mode=map
<http://localhost:8085/cgi-bin/mapserv.exe?map=/ms4w/apps/app/test.map&layer
=states_poly&layer=states_line&mode=map> 

seems to equal this

var loadedMap = new OpenLayers.Layer.MapServer( "OpenLayers WMS",
"http://localhost:8085/cgi-bin/mapserv.exe?layer=states_poly&layer=states_li
ne
<http://localhost:8085/cgi-bin/mapserv.exe?layer=states_poly&layer=states_li
ne> ",
{map: '/ms4w/apps/app/test.map', mode:'map', format: 'png',
transparent:'false'},
 {layers: 'basic'},
{gutter: 15});

Thanks!
