    <p>I'm having a hard time figuring this one out. Seems like no matter what I try, PHP always ends up returning an empty array. Here's the code of my main file(index.php):</p> <pre><code>&lt;script language="javascript" type="text/javascript"&gt; $(document).ready(function(){ $(".ajaxlink").click(function() { callServer(); return false; //Stop link from redirecting }); }); var test = { "testName": "testValue" } var testJSON = JSON.stringify(test); function updatePage(data) { document.getElementById("testDiv").innerHTML = data; } function callServer() { $.ajax({ type: "POST", url: "ajax/server.php", data: testJSON, success: function(data) { updatePage(data); }, //Upon error, output message containing a little info on what went wrong error: function (XMLHttpRequest, textStatus, errorThrown) { alert('An Ajax error occured\ntextStatus = ' + textStatus + '\nerrorThrown = ' + errorThrown + '\nstatus = ' + XMLHttpRequest.status); } }); } &lt;/script&gt; &lt;div id="testDiv"&gt;Something here&lt;/div&gt; &lt;a href="test1.htm" class="ajaxlink"&gt;Link!&lt;/a&gt; &lt;br&gt; </code></pre> <p>This basically runs the callServer() function when you click the "Link!". It then sends the test json data, that is { "testName": "testValue" } to server.php. Firebug reports that the json-data is indeed sent to the server.php.</p> <p>My server.php looks like this:</p> <pre><code>&lt;?php print_r($_POST); ?&gt; </code></pre> <p>This returns the following in the testDiv:</p> <pre><code>Array ( ) </code></pre> <p>The datatype in the .ajax function is not defined, so whatever output the server.php file spits out, it should be readable. All the necessary libraries(json, jquery) are included in my document as well. I'm running this on Apache 2.2 and PHP 5.3.1, but it shows the same on my webserver (which is a host for thousands of websites). The content-type used in the request-header is 'application/x-www-form-urlencoded; charset=UTF-8' so that should work correctly.</p> <p>Thanks for your time. Best regards soren</p>

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.
