    <p>what i am trying to achieve is basically mark the location of all the users logged into my chat which is another thing. so i though i'd use geolocation api (http://code.google.com/apis/gears/api_geolocation.html) and store the generated location in a session variable. but its not working. here is the code-` </p> <pre><code>&lt;?php $my_lat= $_GET['test']; // get data $my_long= $_GET['fname']; $my_name = "vivek"; $lat1=28.635308; $long1=77.22496; //$latitude = $_GET['latitude']; //$longitude = $_GET['longitude'];// get data echo $my_lat.''.$my_long; ?&gt; &lt;script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key='' &amp;sensor=true"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function(){ if(navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { var lat = position.coords.latitude; var longi= position.coords.longitude; var url = 'bam.php'; //post to the server! $.get(url, { test: lat,fname: longi },function(data){ alert('data was passed!'); }); }, function() { //now is when the marking should be done. handleNoGeolocation(true); }); } }); &lt;/script&gt; &lt;script type="text/javascript"&gt; function initialize() { var myLatlng = new google.maps.LatLng(28.635308,77.22496); var myOptions = { zoom: 4, center: myLatlng, mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var thelat = '&lt;?php echo $my_lat;?&gt;'; var thelong = '&lt;?php echo $my_long;?&gt;'; var seslatlng = new google.maps.LatLng(thelat,thelong); alert(seslatlng); var marker = new google.maps.Marker({ position: seslatlng, map: map, animation: google.maps.Animation.DROP, title:"Hello world!", }); } &lt;/script&gt;` </code></pre> <p>and the problem is. that the variable seslatlng is set to (0,0) always which is not what i want. i am new to PHP and i only have rough idea how server side scripting works. can somebody please fix this?</p>

    1. CO1) What do you get when you run echo $my_lat.''.$my_long? 2) Why do you set the center of the map to a hard-coded value instead of centering it based on client's IP location?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
