Google static maps with directions

I took Bedu33 logic in PHP and write it in javascript to generate the Google Maps Static Image in case someone needs it like I did. This code uses the response from the Directions API

var request = directionsDisplay.directions.request;
var start = request.origin.lat() + ',' + request.origin.lng();
var end = request.destination.lat() + ',' + request.destination.lng();
var path = directionsDisplay.directions.routes[0].overview_polyline;
var markers = [];           
var waypoints_labels = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K"];
var waypoints_label_iter = 0;   
markers.push("markers=color:green|label:" + waypoints_labels[waypoints_label_iter] + '|' + start);

for(var i=0;i<request.waypoints.length;i++){
    //I have waypoints that are not stopovers I dont want to display them
    if(request.waypoints[i].stopover==true){
        markers.push("markers=color:blue|label:" + waypoints_labels[++waypoints_label_iter] + '|' + request.waypoints[i].location.lat() + "," +request.waypoints[i].location.lng());
    }           
}

markers.push("markers=color:red|label:" + waypoints_labels[++waypoints_label_iter] + '|' + end);

markers = markers.join('&');

alert("https://maps.googleapis.com/maps/api/staticmap?size=1000x1000&maptype=roadmap&path=enc:" + path + "&" + markers);

You can do it in two steps.

1. Execute directions request from the PHP code to get the encoded polyline
2. Use encoded polyline from step 1 with static maps

E.g.

https://maps.googleapis.com/maps/api/directions/json?origin=Grodno&destination=Minsk&mode=driving&key=YOUR_API_KEY

This will return encoded polyline in routes[0]->overview_polyline->points

Now use the polyline in static map:

https://maps.googleapis.com/maps/api/staticmap?size=600x400&path=enc%3AohqfIc_jpCkE%7DCx%40mJdDa%5BbD%7BM%7D%40e%40_MgKiQuVOoFlF%7DVnCnBn%40aDlDkN%7DDwEt%40%7DM%7DB_TjBy%7C%40lEgr%40lMa%60BhSi%7C%40%7COmuAxb%40k%7BGh%5E_%7BFjRor%40%7CaAq%7DC~iAomDle%40i%7BA~d%40ktBbp%40%7DqCvoA%7DjHpm%40uuDzH%7Dm%40sAg%7DB%60Bgy%40%7CHkv%40tTsxAtCgl%40aBoeAwKwaAqG%7B%5CeBc_%40p%40aZx%60%40gcGpNg%7CBGmWa%5CgpFyZolF%7BFgcDyPy%7CEoK_%7BAwm%40%7BqFqZaiBoNsqCuNq%7BHk%60%40crG%7B%5DqkBul%40guC%7BJ%7D%5DaNo%7B%40waA%7DmFsLc_%40_V%7Dh%40icAopBcd%40i_A_w%40mlBwbAiiBmv%40ajDozBibKsZ%7DvAkLm%5DysAk%7DCyr%40i%60BqUkp%40mj%40uoBex%40koAk_E_hG%7B%60Ac%7DAwp%40soAyk%40ogAml%40%7Bg%40qKsNeJw%5DeuA%7D%60Fkm%40czBmK%7Bg%40wCed%40b%40_e%40dT%7BgCzx%40csJrc%40ejFtGi%60CnB_pFhCa%60Gw%40%7Du%40wFwaAmP%7BoA%7Dj%40etBsRm_AiGos%40aCyy%40Lic%40tFohA~NeoCvC_%7CAWm~%40gb%40w~DuLex%40mUk_Ae_%40o_Aol%40qmAgv%40_%7DAaf%40qhAkMcl%40mHwn%40iCuq%40Nqi%40pF%7D%7CE~CyiDmFkgAoUedAcb%40ku%40ma%40cl%40mUko%40sLwr%40mg%40awIoA_aApDe~%40dKytAfw%40kyFtCib%40%7DA%7Bj%40kd%40usBcRgx%40uFwb%40%7BCulAjJmbC~CumAuGwlA_%5Du_C_PqyB%7BI%7DiAwKik%40%7DUcr%40ya%40up%40%7DkB%7DoCoQ%7Da%40aMyf%40an%40wjEimBuwKiYybC%7DLuyBoJ%7DhBuMieAwd%40i%7BB%7B~%40g%60D_Si%5Dsi%40%7Bk%40cPeSuH_T%7DNct%40kNcmC_Gyr%40mq%40_~AkmA%7DkCksByrE_N%7Bc%40oAcs%40%60J%7Bi%40t%7DByaHxNqt%40tGgxA%7CJ%7BkGeJ_aDsQi_HmFwuAmI%7BdA_XijByFgv%40%7DAiwBxDocAdM%7BlAtSmcAfUmaAptAmbGh~AcvGbwBc%7DHff%40shB~Isp%40nQu%7DB%60UsuCbBok%40l%40%7DzAhIwbA~OuaAnYwp%40rYwe%40%7CNke%40zc%40%7BhBrOwRdo%40sf%40xNaTb_%40uy%40ta%40k~%40xTap%40hl%40uiCre%40unHlIi~AlFsc%40rEkk%40aAce%40mL%7DlAwPcyB_GohBzDsqAtMqtA~h%40weDtFkd%40Bi%60%40_XwfEdAag%40dEkM%60%40zAqApJef%40%7BP_o%40sYys%40ai%40yf%40_j%40y_%40oi%40mVi%5EmFqSwAiPtDuQbc%40_nAtZyaAlEkc%40r%40eq%40%7CAo%5BrTwcAtVuz%40vQ%7Dd%40%7CPmb%40xT%7B%5CzZyd%40jG%7BRzL%7Dh%40jr%40ov%40rFiImFqPiD%7BJ&key=YOUR_API_KEY

I have created a small utility function for my website that does exactly what you need : https://github.com/bdupiol/php-google-static-map-directions

Given an origin, a destination and a array of waypoints (if needed), it gives you a clean Google Static Maps URL with driving path rendered between those points, and sets proper markers.

index.php

<?php

include "static-map-direction.php";

$origin = "45.291002,-0.868131";
$destination = "44.683159,-0.405704";
$waypoints = array(
    "44.8765065,-0.4444849",
    "44.8843778,-0.1368667"
  );

$map_url = getStaticGmapURLForDirection($origin, $destination, $waypoints);

echo '<img src="'.$map_url.'"/>';

static-map-direction.php

<?php

function getStaticGmapURLForDirection($origin, $destination, $waypoints, $size = "500x500") {
    $markers = array();
    $waypoints_labels = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K");
    $waypoints_label_iter = 0;

    $markers[] = "markers=color:green" . urlencode("|") . "label:" . urlencode($waypoints_labels[$waypoints_label_iter++] . '|' . $origin);
    foreach ($waypoints as $waypoint) {
        $markers[] = "markers=color:blue" . urlencode("|") . "label:" . urlencode($waypoints_labels[$waypoints_label_iter++] . '|' . $waypoint);
    }
    $markers[] = "markers=color:red" . urlencode("|") . "label:" . urlencode($waypoints_labels[$waypoints_label_iter] . '|' . $destination);

    $url = "https://maps.googleapis.com/maps/api/directions/json?origin=$origin&destination=$destination&waypoints=" . implode($waypoints, '|');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, false);
    $result = curl_exec($ch);
    curl_close($ch);
    $googleDirection = json_decode($result, true);

    $polyline = urlencode($googleDirection['routes'][0]['overview_polyline']['points']);
    $markers = implode($markers, '&');

    return "https://maps.googleapis.com/maps/api/staticmap?size=$size&maptype=roadmap&path=enc:$polyline&$markers";
}
