[Cartoweb-users] Zooming in after recenter

[Oliver Christen]

Hi

you need to create a simple filtering plugin that implements FilterProvider.
then simply detect if you are doing a recentering (usualy by checking if the recentering variables names exist in $_REQUEST) and if so, do a recenter_scale:

class ClientRecenter extends ClientPlugin implements FilterProvider {   

    public function filterPostRequest(FilterRequestModifier $request) {

        if (!empty($_REQUEST['recenter_x']) && !empty($_REQUEST['recenter_y'])) {
            $request->setValue('recenter_scale', '20000');
            $request->setValue('recenter_doit', '1');
        }
    }
}

if you use id recentering, simply modify/complet the condition to check id_recenter_ids existance

regards
Oliver

  Dear Cartoweb users,

  I have followed the recentering example in Cartoweb to recenter the map on a specific (x,y) coordinate.
  However, if the map is fully shown, then nothing happens.  Only if it is already zoomed does the recentering move the map, which is a logical thing.  How can I make the map zoom to a specified level before recentering? 

  Thanks for any help
