just commenting my example:
it works fine with mapoverlay when doing it correctly >_<
$layer->connectionType = MS_POSTGIS;
$layer->type = MS_LAYER_LINE;

Hi
after the map modification, you could try
$msMapObj->save('/tmp/exportmap.map'); and see if the modifications you have
done are correctly outputed and look ok.
Even if the layer doesnt appear in the layer tree, it should be displayed on
map.
I noticed the layer type may not be set correctly by mapoverlay, try doing it
with mapscript (see below)
I just had a try with inserting a non-existing postgis layer into a mapfile
using mapoverlay ( and a bit of mapscript because some properties are not
supported by mapoverlay) and my layer was displayed correctly on map.
I copy that exemple here, maybe it helps:
$color = new ColorOverlay();
$color->red = 255;
$color->green = 0;
$color->blue = 0;
$style = new StyleOverlay();
$style->action = BasicOverlay::ACTION_INSERT;
$style->color = $color;
$style->size = 5;
$style->symbol = "circle";
$class = new ClassOverlay();
$class->action = BasicOverlay::ACTION_INSERT;
$class->name = 'foobar';
$class->styles = array($style);
$layer = new LayerOverlay();
$layer->name = "routing";
//$layer->connectiontype = "postgis";
$layer->connection = "user=xxx password=yyy host=localhost dbname=zzz";
$layer->data = "the_geom FROM (SELECT id, the_geom FROM public.result WHERE
id = '" . $requ->id . "') AS foo USING UNIQUE id USING SRID=21781";
$layer->classes = array($class);
//$layer->type = "LINE";
$layer->action = BasicOverlay::ACTION_INSERT;
$mapOverlay = $this->serverContext->getPluginManager()->mapOverlay;
$mapOverlay->updateMap($layer);
$msMapObj = $this->getServerContext()->getMapObj();
$msLayer = $msMapObj->getLayerByName('routing');
$msLayer->set('connectiontype', MS_POSTGIS);
$msLayer->set('type', MS_LAYER_LINE);
if (!$msLayer)
throw new CartoserverException("Routing results layer " .
"$routingResultsLayer not found");
$msLayer->set('status', MS_ON);
$msMapObj->save('/tmp/exportmap.map');

I've tried what you told me Oliver, but with no success.
With the lines you gave:
$msLayer =
$this->serverContext->getMapObj()->getLayer($result->layers[0]->index);
$msLayer->set('status', MS_ON);
I also included these other lines:
$msLayer->set('type', MS_LAYER_RASTER);
$msLayer->setProcessing("BANDS=1,2,3");
because the layer I try to create is a raster image.
The only solution I see is having a set of empty layers in the mapfile (and
also in the layers.ini), hidden from the menu layer tree, that when a user
specifies a raster to be shown, is "put" in the first empty layer available.
But this is something here we don't like very much.
I'm using ajax, but I made a test without it, and no result either...
Has someone else had trouble tring to create a raster layer with MapOverlay?

By the way, inserting a layer via mapOverlay only create a new layer on
the map image, it will not create a new entry in the menu layer tree.
Layers in the layer tree can only be selected/unselected if they already
exist in your layers.ini, as far as I know.
You could eventualy use the same mecanism as the ogcLayerLoader and
trigger layer insertion via the use of the userLayers variable. See
ClientOgcLayerLoader, the parts around $userLayer = new UserLayer();
I have never do that myself but I presume it should be possible.

You're right!
Here is the code that tries to make visible a new layer
(simulacionesGrupo):
public function filterPostRequest(FilterRequestModifier $request) {
$layerList = $request->getValue('layers');
$layerList[] = 'simulacionesGrupo';
$request->setValue('layers', $layerList);
$this->tempinfo = implode('--', $layerList);
}
it is in the Client part of a plugin that implements FilterProvider.
To create the layer:
function initializeRequest($requ) {
if ($requ) {
$pluginManager = $this->serverContext->getPluginManager();
if (empty($pluginManager->mapOverlay))
throw new CartoserverException("mapOverlay plugin not
loaded, ");
$mapOverlay = $pluginManager->mapOverlay;
$layer = new LayerOverlay();
$layer->name = "simulacionesGrupo";
$layer->action = BasicOverlay::ACTION_INSERT;
$layer->data = "raster/ozono.99.tif";
$result = $mapOverlay->updateMap($layer);
}
}
it is in the Server part of the same plugin that extends
ClientResponderAdapter.
Anyway, if the "simulacionesGrupo" layer is defined in the mapfile, and
the line with ACTION_INSERT is not used in the last piece of code, and the next
line is commented in 'layers.ini':
; mapInfo.initialMapStates.default.layers.simulacionesGrupo.selected =
true
it doesn't show up in the main map.

Hi
without looking at your code, I cant really know what may or may not
happens.

Subject: [Cartoweb-users] Problem creating new layers
Hi all!
I'm using the 'mapOverlay' plugin in order to modify the layers of
my project. It has worked well to modify existing layers, but when I try to
insert a new one, it simply does nothing.
Perhaps it is related to another problem I'm facing: I can only
hide a layer with "FilterProvider". If I try to make visible a layer that is
not set as visible by default in the "layers.ini" file, nothing happens...
I hope someone could help!
Thanks in advance!
