Your Location from the BT SDK (Web21c) in Google Maps

The steps to setting up a very  basic example of the BT Web21c location service are below.  Over the coming weeks I will evolve these example and hope to release a new version of the PHP examples provided on the official Web21c site.

 This app results in in a link which when clicked displays the mobiles current location in google maps.

If you need to get the SDK set up you may find some help in this post.  When the examples have  evolved I will publish a new step by step example of how to get set up in the first place.

1 ..  Before you can view a phones location you must first register the user who you wish to track. This is done using the addUser.php page in the examples directory. I have added the code below:




WhitelabelAuthentication();     $wla->addUser([](;     //  dump response     var\_dump($wla->getAllUsers()); ?>  \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Please note that you will need to change "[](" to the email address of the user that you wish to be added.  The bottom line will display any errors that are returned.  2 ..  When the user has been added they will recieve a password via email. 3 ..  With the password you will now be able change three variables in locate.php  and then run the file. The three variables you need to change are : $deviceId = 'tel:+440000000000'; $username = [youremail@mail]([.](; $password = "YOURPASS"; \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ locate.php \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_  WhiteLabelAuthentication(); $wla->login($username, $password);  //  locate mobile $location = $web21c->Location(); $location->web21cUser = $wla->web21cUser; try {  $r = $location->getGeoLocation($deviceId); } catch (Web21cPermissionDeniedException $e) {  print "requesting device owner's permission to be located ..\\n";  print "try again later when the owner may have responded\\n";  $access = $web21c->LocationPermission();  $access->web21cUser = $wla->web21cUser;  $access->requestPermission($deviceId); } // var\_dump($r->geoLocation); echo 'Longitude : '.$r->geoLocation->longitude. '
'; echo 'Latitude : '.$r->geoLocation->latitude. '
'; echo "Click below to see the location of mobile number ".$deviceId."
"; echo "Google Maps "; //echo 'start : '.$r->getGeoLocation()->getLongitude(); ?>
