Hi Giuseppe
After looking at the code in ClientLayers, it seems layer_select can only be
used via GET and not POST, so this wont work that way.
When sending the form via POST, the array list is passed in parameter so you
should be able to add the layer wanted via filterPostRequest
Try something like that:
public function filterPostRequest(FilterRequestModifier $request) {
$layerList = $request->getValue('layers');
$newLayers =
array('CAR_Group','VIN_layer_1','VIN_layer_2','VIN_layer_2');
$newLayerList = array_merge($layerList, $newLayers);
$request->setValue('layers', $newLayerList);
}
By the way, 'recenter_bbox' and 'recenter_scale' are exclusive, its either
one or another but not both. 'recenter_bbox' calculate automaticaly the
scale based on the bbox.
And show_crosshair will NOT be triggered when using a 'recenter_bbox', only
with 'recenter_scale' or recenter_x/recenter_y
Hope this cover all the issues here.
regards
Oliver
Hi Oliver,
I red the doc, but I was not able to get my target.
I performed some tests amd I send you my code. Only the recenter option
works well.
My plugIn let the user to choose a name of a building which has been
selected by a quary and linked to recenterBox, so when the user click on
one
item of the displayed list of buildings the map is recentered on it.
I'm working on Cartoweb 3.2 in Win env.I tried to put the values in a
direct
mode both with one-quote and double quotes and as int value (for the
crosshair 1 or '1' or "1" , but nothing ... in $sel_layers there is the
real
name of the layer and not the label. I tried both with a group name and
with
a list of elementary layers .
Any suggestion/correction ?
thanks in advance and best regards
Giu

$request->setValue('recenter_scale', "2000");
$request->setValue('recenter_bbox', $recenterBbox);
