Subject: Re: [OpenLayers-Users] Display specific layer from mapfile
Thanks for the response, you are right both my layers are set as STATUS
DEFAULT. However when I set one layer status to ON and the other OFF and view
via mapserver (cgi-bin/mapserv.exe?) I can only see a blank white screen and
via open layers I get the error message 'WMS server
error.WMSLoadGetMapParams()'.
The same happens if both my layers are set to ON, I seem to only be able to
view them when status set to DEFAULT.
Thanks for any help in advance

Hi,
from your code both layers should be baselayers. That means only one layer
would displayed. That seems, that in your mapfile both layers have status
default.

Betreff: [OpenLayers-Users] Display specific layer from mapfile
Hi,
I am having trouble displaying a specific layer from my mapfile. I have two
layers called '250' and 'uk'. I wish to display my '250' layer origninally,
then zoom closer to display my 'uk' layer. however both my layers are currenlty
displayed at all times.
Am i going about this the correct way by having two variables 'layer1 and
'layer2' for layers from the same mapfile?
Currently my code is as follows
var bounds = new OpenLayers.Bounds(0, 0, 660046, 1229782);
var map, layer1, layer2;
var options = { maxExtent: bounds, maxResolution: 600, numZoomLevels: 10};
layer1 = new OpenLayers.Layer.WMS("OpenLayers WMS",
"http://127.0.0.1/cgi-bin/mapserv.exe?";, { layers: "250", map:
'/ms4w/apps/openlayers-2.8/data/uk2.map', minZoomLevel: 1, maxZoomLevel: 4 },
{ gutter: 15 });
layer2 = new OpenLayers.Layer.WMS("OpenLayers WMS",
"http://127.0.0.1/cgi-bin/mapserv.exe?";, { layers: "uk", map:
'/ms4w/apps/openlayers-2.8/data/uk2.map', minZoomLevel: 5, maxZoomLevel: 10 },
{ gutter: 15 });
map.addLayer(layer1, layer2);
Thanks for any help in advance
Paul
