php - Cannot populate JSON request with correctly formatted data -


i trying populate json request data coming phpsearch.php file (shown here)

<?php include "base.php"; $name = $_get["name"]; $query = "select lat, lng markers name = '".$name."'"; $result = mysql_query($query); $json = array(); while($row = mysql_fetch_array ($result))      {   $bus = array(         'lat' => $row['lat'],         'lng' => $row['lng']     );     array_push($json, $bus); } $jsonstring = json_encode($json); echo $jsonstring; ?>

the data shows in console in format:

[{"lat":"37.730267","lng":"-122.498589"}]

the route calculation function @ bottom of question, had used asynchronous json rewquest causing code execjte before origin value set, being set looks incorrect

how can make sure latitude , longitude results in correct json format? json request looks this:

 request url:https://maps.googleapis.com/maps/api/js/directionsservice.route?4b0&5m4&1m3&1m2&1dnan&2dnan&5m4&1m3&1m2&1d37.738029&2d-122.499481&6e1&8b1&12sen-gb&100b0&102b0&callback=_xdc_._1rqnjk&token=80599

route calculation code:

  function calcroute() {         var startname = document.getelementbyid('start').value;         var endname = document.getelementbyid('end').value;         var waypts = [];         var checkboxarray = document.getelementbyid('waypoints');         (var = 0; < checkboxarray.length; i++) {           if (checkboxarray.options[i].selected == true) {             waypts.push({                 location:checkboxarray[i].value,                 stopover:true});           }         }  $.ajax({     url:'phpsearch2.php',      datatype:'html',      data:{name:startname},     async:false,     success:function (result) {     console.log(result)     origin = new google.maps.latlng(result[0].lat, result[0].lng); }});      var end = new google.maps.latlng('37.738029', '-122.499481');     var request = {             origin: origin,             destination: end,             waypoints: waypts,             optimizewaypoints: true,             travelmode: google.maps.directionstravelmode.walking         };              directionsservice.route(request, function(response, status) {         document.write('<b>'+ origin +'</b>');           if (status == google.maps.directionsstatus.ok) {             directionsdisplay.setdirections(response);             var route = response.routes[0];             var summarypanel = document.getelementbyid('directions_panel');             summarypanel.innerhtml = '';             // each route, display summary information.             (var = 0; < route.legs.length; i++) {               var routesegment = + 1;               summarypanel.innerhtml += '<b>time walkabout </b><br>';               summarypanel.innerhtml += '<b>from ' + startname + '   </b>';               summarypanel.innerhtml += '<b>to ' + endname + '('+ route.legs[i].distance.text +')</b><br>';           }            }         });      }

the latlng constructor takes 2 numbers arguments, you're passing json object. latitude , longitude properties out , pass numbers directly, this:

function (result){     origin = new google.maps.latlng(result[0].latitude, result[0].longitude); }

i'm guessing on specific properties, may want console.log(result) see exact object structure.
