[Cartoweb-users] Howto highlight points on map based on resultsreturned from sql database

[Oliver Christen]

Hi Max

you need to add

   public function replacePlugin() {
        return 'outline';
    }

to your ClientPointDraw class, otherwise it will be ignored

or you could have simply used the 'show_crosshair' parameter
$request->setValue('show_crosshair', 1);
to display a cross symbol on the recenter point

regards
Oliver
