Further to this, I have removed the featureClass parameter, and included
extractAttributes: true:
var wfs = new OpenLayers.Layer.WFS("API WFS",
"http://10.65.192.1/cgi-bin/apiwfs.exe?";,
{typename: 'apiaries_dev', maxfeatures: 100, extractAttributes: true},
{scales: [150000, 10]});
map.addLayers([wms1,wfs]);
I have added:
var options = {
hover: true,
onSelect: function(feature) {
OpenLayers.Util.getElement('apiary').innerHTML =
feature.attributes.apiary_id;
}
};
var select = new OpenLayers.Control.SelectFeature(wfs, options);
map.addControl(select);
//select.handler.stopDown = false;
//select.handler.stopUp = false;
select.activate();
This allows me to hover over each point and select it, however I am struggling
to get at the attributes still. Here is a sample of the GML returned by
Mapserver:
<gml:Point srsName="EPSG:2193">
<gml:coordinates>1824867.377072,5534693.953457</gml:coordinates>
</gml:Point>
</ms:msGeometry>
<ms:apiary_id>88883</ms:apiary_id>
<ms:x_nzmg>2734900</ms:x_nzmg>
<ms:y_nzmg>6096500</ms:y_nzmg>
<ms:beekeeper_reg_no>H0733</ms:beekeeper_reg_no>
<ms:maf_id>7</ms:maf_id>
</ms:apiaries_dev>
</gml:featureMember>
</wfs:FeatureCollection>
There are 5 attributes: apiary_id, x_nzmg, y_nzmg, beekeeper_reg_no, maf_id
However, the onSelect function above returns "undefined" into the apiary div.
How should I reference the attribute fields in each feature?
Many thanks,

I have a n OpenLayers map that displays point markers for a WFS layer served
from Mapserver. The source data is an OGR Virtual layer reading froma table in
a SQL-server database with x,y fields in a table.
Here is the OL snippet that adds the layer:
var wfs = new OpenLayers.Layer.WFS("API WFS",
"http://10.65.192.1/cgi-bin/apiwfs.exe?";,
{typename: 'apiaries_dev', maxfeatures: 100},
{scales: [150000, 10], featureClass: OpenLayers.Feature.WFS});
map.addLayers([wms1,wfs]);
map.setBaseLayer(wms1);
The layer displays fine on top of a base WMS layer.
I want to be able to select a single marker using a CTRL-click, and send the
attributes to a div below the map. Next I want to be able to capture a new
location for the marker using ALT-click, and send the map coordinates to a
separate div. From there, I will formulate a POST to a server to update the
location in the source table.
The code for capturing the coordinates is as follows:
//add various map controls
var control = new OpenLayers.Control();
OpenLayers.Util.extend(control, {
draw: function () {
// this Handler.Point will intercept the ctrl-mousedown
// before Control.MouseDefault gets to see it
this.point = new OpenLayers.Handler.Point( control,
{"done": this.notice},
{keyMask: OpenLayers.Handler.MOD_ALT});
this.point.activate();
},
notice: function (bounds) {
document.getElementById('apiary').innerHTML = bounds;
}
});
map.addControl(control);
This works.
However, I have no idea as to how to select and then get at the attributes of
the WFS layer. Any help appreciated.
Many thanks,
Robert Sanson
