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

Paul

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
