Hello Nina!! I believe that you want to get the info of all the layers of your map at a single click into a determined position, right?
So, at QUERY_LAYERS param, you'll have to write what Mika said, but leaving the index off (map.layers.params.LAYERS) , this way, all the array will be sent to the query! (I beleve this should work)! You said about layerlist... If you notice, the "layerlist" at the OpenLayers site's example is declared as a list of layers names: http://trac.openlayers.org/wiki/GetFeatureInfo (line 3 of the first code ;) ) (I don't know if you have declared it.. but.. it's there...hehehe) Oh and...I don't know if you have overlays in your map, but, if you do, maybe is better to take care about the visibility of layers... I've made some tests and discovered that even when a overlay is not showed in the map, the getFeatureInfo returns it's infos when you use a query param like this (map.layers.params.LAYERS), because you pass the layer to the query anyway... XD Only some adjusts can fix this, if necessary.. =) I hope I have helped! =) Rodrigo On Thu, Sep 25, 2008 at 8:24 AM, Lehtonen, Mika <[EMAIL PROTECTED]> wrote: > Hi Nina, > > I use this to get a particular layer info: > > QUERY_LAYERS: map.layers[1].params.LAYERS > > I really don't know how to choose all the layers, but maybe someone knows. > I don't know what happens if you leave the index off... > > cheers, > mika > > > > > Nina Helle-Mildt kirjoitti: > > Hey, > > > > thanks for your replay Ian.
