[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);
 	     
 
  }
 
 ...
 
 
 }
