[Cartoweb-users] Plugin Layer / AddUserLayer

[François Prunayre]

Hi list, I'm having problem when adding wms layers and setting layer name
when a layer with the same name is already in the mapfile.

Currently, the layer plugin is doing that when it try to set the layer name
:

if (!empty($msLayer)) $layer->label = $msLayer->getMetadata('wms_title');

if (empty($layer->label)) $layer->label = $layer->id;

But sometimes, user could load a layer using a WmsBrowserX interface ... and
wms_name could be equal to a layer which is already in the mapfile. In that
case, we could get the wms_title of the previous layer in the mapfile.
Because the $msMapObj->getLayerByName return only one layer. (Maybe we
should not be able to add a layer with the same name)
 
I would have prefer to be able to force the layer label when using the
AddUserLayers function. If no label set for the user layer, use the
wms_title if the layer is already here if not use id. If the layer is not a
wms layer, this will always return the id for the name. So It could be
better to force layer label using UserLayer.
if (empty($layer->label)) {

if (!empty($msLayer))

$layer->label = $msLayer->getMetadata('wms_title');

else

$layer->label = $layer->id;

} 

Is that a good way to set the layer label ? 
 
Thanks for your comments. 
Francois
