[Cartoweb-users] how to change layer selection by code in a plugIn

[giuseppe.derossi at email.it]

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

class myNewPlugin extends  ClientPlugin implements  Sessionable,
GuiProvider, FilterProvider 
{
...

 public function filterPostRequest(FilterRequestModifier $request) {

...
   $recenterBbox= "$x1, $y1, $x2, $y2";
   $cross_ok ="1";
   $sel_layers="CAR_Group,VIN_layer_1,VIN_layer_2,VIN_layer_2";
	      
   $request->setValue('show_crosshair',  $cross_ok);
   $request->setValue('recenter_scale',  "2000");
   $request->setValue('recenter_bbox', $recenterBbox); 
   $request->setValue('layer_select',$sel_layers);
	     

 }

...
