Dear all,
I might open a topic in a wrong forum, because I do not know whether I
should ask this question in Mapserver or OpenLayers forum. If I did, I feel
sorry about that.
I want to query the layer with using openlayers. However, I do not know how
to 'call' the templates from mapfile to the html file.I have found topics
about query using mapserver and openlayers, but I have still no idea how to
code in html file. The query function is fine when using mapserver alone.
In the mapfile, I have put metadata into web like this:
WEB
HEADER "/ms4w/Apache/htdocs/web_header.html"
FOOTER "/ms4w/Apache/htdocs/web_footer.html"
EMPTY "empty.html"
Metadata
"wms_title" "WMS"
"wms_onlineresource"
"http://localhost/cgi-bin/mapserv.exe?map=c:/ms4w/Apache/htdocs/test.map&";
"wms_srs" "EPSG:4269"
"wms_feature_info_mime_type" "text/html"
END
template "/ms4w/Apache/htdocs/web.html"
imagepath "/ms4w/Apache/htdocs/tmp/"
imageurl "/tmp/"
END
PROJECTION
"init=epsg:4269"
END
And in the layer, data from postgresql postgis (with attribute ID) was used
with metadata:
Name "Abc"
metadata
"wms_title" "Abc"
"wms_srs" "EPSG:4269"
End
.....
I also have put header footer in layer and template in the class
Class
Name "abc"
Template "/ms4w/Apache/htdocs/query.html"
......
END
The code in html file:
var layer = new OpenLayers.Layer.MapServer( "ABC WMS",
"http://localhost/cgi-bin/mapserv.exe?map=c:/ms4w/Apache/htdocs/test.map&";,
{layers: 'Abc'} );
I tried {layers: 'Abc', mode: 'query', params ='ID'} but it did not work.
I found an example of query: http://www.co.sweet.wy.us/mapserver/map.html
I want to query the layer by a click instead of dragging and a new window
come out to display information.
How can I make this in html file?
Furthermore, I find many examples using new OpenLayers.Layer.WMS. But when I
use it, it displays nothing. I can only use new OpenLayers.Layer.MapServer
to display map. What is the problem?
Thanks,
Aypes
