Hi,
I have a WMSGetFeatureInfo control and would like to send an additional post
parameter when it is executed - how could I do that?
What I have below does not send the 'WEEDSQL' parameter which I have in my
layer with the WMSGetFeatureInfo request
Thus I get an error in my PostGIS layer because the data statement for
MapServer is incomplete..
//the query layer
var observations = new OpenLayers.Layer.WMS(
"Observations",
"/cgi-bin/mapserv564agg?map=/var/www/mapdata/projects/calipc/ca_base_v2.map",
{layers: 'observations', 'transparent': true,
'PHPSESSID':'<?php print session_id() ?>', 'WEEDSQL':'1 = 0'},
{isBaseLayer:false, opacity:0, visibility:true,
singleTile:true, displayInLayerSwitcher:false }
);
...
// the id control
var info = new OpenLayers.Control.WMSGetFeatureInfo({
url:
'/cgi-bin/mapserv564agg?map=/var/www/mapdata/projects/calipc/ca_base_v2.map',
title: 'Identify features by clicking',
queryVisible: true,
layers: [observations],
WEEDSQL: "species_id = 1",
eventListeners: {
getfeatureinfo: function(event) {
var obquerystring1 = "species_id = 1";
observations.mergeNewParams({'WEEDSQL':obquerystring1});
map.addPopup(new OpenLayers.Popup.FramedCloud(
"manzana",
map.getLonLatFromPixel(event.xy),
null,
event.text,
null,
true
));
}
}
});
map.addControl(info);
info.activate();
How can I send the WEEDSQL parameter that is included in my layer above with
the getfatureinfo request ?
Thanks
Karsten
