    <p>I want to pass variables to PHP from JavaScript. I've read about not being able to do this without a AJAX call, or putting it in the URL in JavaScript and then working with <code>$_GET</code>. The problem is that my variables are created on initialize (on window load) so if I try <code>$_GET</code> I get stuck in an infinite loop.</p> <p>The variables are <code>lati</code> and <code>longi</code>.</p> <p>Here is my JavaScript (without the AJAX call, since that created an infinite loop etc..):</p> <pre><code>var map; function initialize() { var mapOptions = { zoom: 12, streetViewControl: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions); // Try HTML5 geolocation if(navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { var pos = new google.maps.LatLng(position.coords.latitude, position.coords.longitude); var lati = position.coords.latitude; var longi = position.coords.longitude; map.setCenter(pos); }, function() { handleNoGeolocation(true); }); } else { // Browser doesn't support Geolocation handleNoGeolocation(false); } var length = locationsArray.length, element=null; for (var i = 0; i &lt;length; i++) { element= locationsArray[i]; var element1 = element.split(";"); var posi = new google.maps.LatLng(element1[0],element1[1]); var marker = new google.maps.Marker({ position: posi, map: map, icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter_withshadow&amp;chld='+i+'|e74c3c|333333', url: 'index.php?id='+i+'#eventDetails' }); google.maps.event.addListener(marker, 'click', function() { window.location.href = this.url; }); } } google.maps.event.addDomListener(window, 'load', initialize); </code></pre> <p>The PHP where I want to use the variable:</p> <pre><code>$url="http://build.uitdatabank.be/api/events/search?key=AEBA59E1-F80E-4EE2-AE7E-CEDD6A589CA9&amp;latlng=".$lati.";".$longi."!10km&amp;format=json"; $events= json_decode(file_get_contents($url)); </code></pre>

    1. COjQuery ajax is what you're looking for. What have you tried?

    2. COI've tried this: $.ajax({ type: 'POST', url: 'index.php', data: {variable : lati, variable2: longi} }); and then getting them in my .php with this: $lati = $_POST['variable']; $longi = $_POST['variable2']; I have no idea if this is the right way though, since I suck at ajax.

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.
