gpx

Hi...
Great product.

I was just wondering if it possible to load a gpx file and show a route on the map?

Hi,

This package doesn't natively support this, however I'm sure you can achieve this using PHP itself, you could read the GPX file, and iterate over each of the found lat/longs and draw polylines from the initial point and the next. Something along the lines of the following:

Mapper::map(53.381128999999990000, -1.470085000000040000);
$gpx = simplexml_load_file("test.gpx");
$points = [];

foreach ($gpx->trk as $trk) {
    foreach($trk->trkseg as $seg) {
        foreach($seg->trkpt as $pt) {
            $points[] = [
                'lat' => $pt["lat"], 
                'lon' => $pt["lon"]
            ];
        }
    }
}
unset($gpx);

$previousPoint = null;

foreach ($points as $point) {
    if ($previousPoint !== null) {
        Mapper::polyline([['latitude' =>  $previousPoint['lat'], 'longitude' => $previousPoint['lon']], ['latitude' => $point['lat'], 'longitude' => $point['lon']]]);
    }
    $previousPoint = $point;
}
