php - Reverse Geocode On Google Maps api v3 -


i wonder whether may able me please.

i using code shown below correctly plot markers retrieved mysql database on google map.

<script type="text/javascript">              //sample code written august li              var icon = new google.maps.markerimage("images/location-marker-2.png")              new google.maps.point(16, 32);              var center = null;              var map = null;              var bounds = new google.maps.latlngbounds();              function addmarker(lat, lng, info) {              var pt = new google.maps.latlng(lat, lng);              bounds.extend(pt);              var marker = new google.maps.marker({              position: pt,              icon: icon,              map: map              });              }              function initmap() {              map = new google.maps.map(document.getelementbyid("gmaps-canvas"), {              center: new google.maps.latlng(0, 0),              zoom: 6,              scrollwheel: true,                   draggable: true,               maptypeid: google.maps.maptypeid.satellite              });                 <?php                          include("admin/link.php");                         include("admin/opendb.php");                          $query = mysql_query("select * `detectinglocations` `locationid` = '$lid'");                         while ($row = mysql_fetch_array($query)){                             $locationname=$row['locationname'];                             $osgb36lat=$row['osgb36lat'];                             $osgb36lon=$row['osgb36lon'];                             echo ("addmarker($osgb36lat, $osgb36lon,'<b>$locationname</b><br/>');\n");                         }                              mysql_close($connect);                  ?>                           center = bounds.getcenter();                          map.fitbounds(bounds);                         } </script>

what i'm trying add further functionality allows users click on map plot new markers, in essence using pre-existing marker database point work from, performing reverse geocode.

i've been researching number of days , i've tried implement whole host of tutorials, can't seem both parts of functionality working.

i know enable on-click event need incorporate along lines of:

google.maps.event.addlistener(map, 'click', function(event) { marker.setposition(event.latlng) geocode_lookup( 'latlng', event.latlng ); }); }

but must admit i'm little unsure else need incorporate.

i wondered whether may able take @ please, , i'd grateful if show me i've gone wrong.

many , kind regards

i wrote separate maps page click-to-reverse-geocode functionality

http://jsfiddle.net/zdqem/

the address details confusing work with, think. results array, @ different levels of precision, 1 might include county, state, street address. use results[0]. details in docs: https://developers.google.com/maps/documentation/javascript/geocoding#geocodingresponses

if need specific information sure way obtain iterate through whole results array until find need (types[] containing postal_code, example).

    google.maps.event.addlistener(map, 'click', function(event) {       usermarker = new google.maps.marker({         map: map,         position: event.latlng       });        geocoder.geocode({'latlng': event.latlng}, function(results, status) {         if(status == google.maps.geocoderstatus.ok) {           if (results[0]) {             alert(results[0].formatted_address);           }           else {             alert("no results");           }         }         else {           alert("geocoding unsuccessful: status " + status);         }       });     });

where in code?

<script type="text/javascript">          //sample code written august li          var icon = new google.maps.markerimage("images/location-marker-2.png")          new google.maps.point(16, 32);          var center = null;          var map = null;          var bounds = new google.maps.latlngbounds();          function addmarker(lat, lng, info) {          var pt = new google.maps.latlng(lat, lng);          bounds.extend(pt);          var marker = new google.maps.marker({          position: pt,          icon: icon,          map: map          });          }          function initmap() {          map = new google.maps.map(document.getelementbyid("gmaps-canvas"), {          center: new google.maps.latlng(0, 0),          zoom: 6,          scrollwheel: true,               draggable: true,           maptypeid: google.maps.maptypeid.satellite          });             <?php                      include("admin/link.php");                     include("admin/opendb.php");                      $query = mysql_query("select * `detectinglocations` `locationid` = '$lid'");                     while ($row = mysql_fetch_array($query)){                         $locationname=$row['locationname'];                         $osgb36lat=$row['osgb36lat'];                         $osgb36lon=$row['osgb36lon'];                         echo ("addmarker($osgb36lat, $osgb36lon,'<b>$locationname</b><br/>');\n");                     }                          mysql_close($connect);              ?>                       center = bounds.getcenter();                      map.fitbounds(bounds);                       var geocoder = new google.maps.geocoder();                       google.maps.event.addlistener(map, 'click', function(event) {                        var usermarker = new google.maps.marker({                          map: map,                          position: event.latlng                        });                       geocoder.geocode({'latlng': event.latlng}, function(results, status) {                        if(status == google.maps.geocoderstatus.ok) {                          if (results[0]) {                            alert(results[0].formatted_address);                          }                          else {                            alert("no results");                          }                        }                        else {                          alert("geocoding unsuccessful: status " + status);                        }                      });                    });                  } </script>
