[Geomoose-users] identify on layers you don't want visable

[Brian Fischer]

Jim, the only probably I see with your suggestion is there is no way to define that in the mapbook for a user.  After some more investigation by one of our developers we learned that this is supported already but found a bug.

>From our developer:
" You can already identify layers that aren't visible on the map and don't appear on the catalog already through the mapbook.  Just turn the status of the layer off, remove the layer from the catalog tag, and then add the hidden layers tag to the identify service. 

There is however a bug with the identify tool.  You can't use the visiblelayers attribute (<input type="visiblelayers" name="layers"/>) with the hiddenlayers attribute (<input type="hidden" name="layers" value="mapsource/layer:mapsource/layer" />).  Whichever is declared second will overwrite the first attribute when passing the layer parameters to the identify service.  I changed the name attribute to "hiddenlayers" (<input type="hidden" name="hiddenlayers" value="parcels/parcels" />) so that both the "layer" attribute and the "hiddenlayers" attribute are being passed to the identify service and then I combine them there."

We'll probably submit a patch for this small change if this makes sense to others.

My understanding is you want some layers to always be identified while the rest are only identified if they are visible.

In that case, would the following work in the mapbook?

<input type="visiblelayers" name="layers"/> <input type="hidden" name="layers" value="mapsource1/layer1:mapsource1/layer2:mapsource2/layer1"/>

Presuming everything is following the HTML forms spec for multiple valued fields, I would expect this would call identify.php with:
identify.php?layers=[whatever is on]&layers=mapsource1/layer1:mapsource1/layer2:mapsource2/layer1&...

I haven't checked if this all actually works, but seems less intrusive than adding another type.
GeoMoose JS might need to be modified to handle multiple parameters of the same name.
Identify.php might need to be modified to check for multiple parameters of the same name. (The ruby cgi library assumes this is always true. I don't know about PHP.)

If this isn't feasible I would still recommend using a type="hidden" field with maybe a name of layers2 or something.

Essentially the only way the layers get passed into the identify service is to use <input type="visiblelayers" name="layers"/> or to specify them in a list.  And also the status has to be =on.  This also means each map image get's requested whether you want it or not.
