    <p>I've been comparing my code to other examples on the web and I still can't find my errors. When I load the page and click submit, nothing happens on the screen. However, in Firebug I receive the <code>POST 200 OK</code> and the PHP script that should be on screen is spelled out in the POST response tab. </p> <p>Since Firebug is responding appropriately, I am confused as to what is wrong.</p> <p>Basic HTML form</p> <pre><code>&lt;form id="form" action="" method="post"&gt; &lt;input type="submit" name="submit" id="submit" value="submit"/&gt; &lt;/form&gt; &lt;div id="results"&gt;&lt;/div&gt; </code></pre> <p>jQuery creates a JS object. The object is sent through <code>JSON.stringify</code> and <code>JSON.parse</code>. The submit event handler fires off the <code>$.ajax</code>. JSON data is passed to <code>ok.php</code> and it should return the PHP info called in the script, in theory.</p> <pre><code>var addIt = new Object(); addIt.one = "one"; addIt.two = 2; addIt.three = addIt.one +" + "+ addIt.two +" = "+ "three"; $jsonAddIt = JSON.stringify(addIt); $jsonAddIt = JSON.parse($jsonAddIt); $('#submit').click(function(e){ e.preventDefault(); $.ajax({ type: 'POST', url: 'ok.php', dataType:'json', data: ({ json:$jsonAddIt }), success:function(data) { $("#results").html(data); } }); }); </code></pre> <p>PHP</p> <pre><code>&lt;?php $ajaxInfo = $_POST["json"]; if ($ajaxInfo !="") { echo "info transfered"; } else echo "nothing"; ?&gt; &lt;div id="returned"&gt; &lt;?php print_r($ajaxInfo); ?&gt; &lt;/div&gt; </code></pre>

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.
