Need help with getfeatureinfo for OpenLayers/WMS

dakan

Hi Folks, I am developing a GIS web-map and am hoping someone could help me with the getfeatureinfo method to call information from a WMS layer. I have the web-map working in that I can display various WMS/WFS layers. Behind the layers that are attribute tables and everything is hosted by GeoServer 2.8.2. I'm trying to figure out how to click on a feature on a WMS layer and call the attributes of that into a pop-up. I've looked at a load of examples on line but can't get any of them to work on my map.

Here is the code for a map.js page. I have deleted the code for most of the layers for convenience sake. There is an attribute behind the DART station layer called stop_name.

var map;

function initMap() {

    //initialise variables
    var osmlayer;
    var point;
    var dlr_libraries_wfs;
	var dlr_libraries_wms;
	var dlr_townlands_wms;
	var dlr_mtowers_wfs;
	var dlr_mtowers_wms;
	var dlr_DART_wfs;
	var dlr_dart_wms
	var dlr_war_memorial_wfs
	var dlr_war_memorial_wms
	var info;

    //create new map object
    map = new OpenLayers.Map("mymap");

    //create new OSM base layer
    osmlayer = new OpenLayers.Layer.OSM("Open Street Map");

    //create WMS layers

	// DART Station Layer.
	dlr_DART_wfs = new OpenLayers.Layer.Vector("DART Stations (WFS)",
        {
        strategies:[new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS(
                {
                version: "1.1.0",
                url: "http://localhost:8080/geoserver/wfs",
                featureType: "EastC_Darts",
                featurePrefix: "egm715",
                featureNS: "http://geoserver.org/egm715",
                }
            ),
        visibility: false,
        }
    );

	dlr_dart_wms = new OpenLayers.Layer.WMS("DLR DART Stations (WMS)", "http://localhost:8080/geoserver/egm715/wms",
        {
        layers: "egm715:EastC_Darts",
        transparent: true
        }, {
        projection: "EPSG:3857",
        opacity: 0.5,
        visibility: false
        }
    );
	
	
    //add layers to the map
    map.addLayers([osmlayer, dlr_libraries_wfs, dlr_libraries_wms, dlr_DART_wfs, dlr_dart_wms, dlr_war_memorial_wfs, dlr_war_memorial_wms ]);

    //add LayerSwitcher control object
    map.addControl(new OpenLayers.Control.LayerSwitcher());


    // define point as a new LonLat object and transfom
    point = new OpenLayers.LonLat(-6.1832, 53.2560); 
    point.transform("EPSG:4326", "EPSG:900913");
	
	
    //centre the map and set zoom level
    map.setCenter(point, 11.7);

}

I'm grateful to anyone who gets back to me with some help. Thanks.
