    <p><code>$.post()</code> is an abbreviated form of the $.ajax() structure. I usually prefer to use the <code>$.ajax()</code> structure because:</p> <ul> <li>It's easier to see if I've missed anything</li> <li>I can more easily add additional params, such as <code>asynch: false,</code></li> <li>When new to ajax I found it considerably easier to troubleshoot this structure</li> </ul> <p>In your case, you might find your problem easier to solve in a <code>$.ajax()</code> structure, since it would be easier to see that <em>a second ajax call (that depends on the outcome of a first ajax call) must happen in the success function of the first ajax call</em>.</p> <p>Here is a standalone example (too bad jsFiddle cannot handle ajax...):</p> <p>TESTER.PHP</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function() { $('#eml').focus(); $('#mybutt').click(function() { var $a = $('#eml').val(); var $b = $('#pw').val(); //alert('Email: ' +$a+ ' Pass: ' +$b); $.ajax({ type:"POST", url: "yourphpfile.php", data: 'email=' +$a+ '&amp;pass=' +$b, success: function(data) { alert(data); var aData = data.split('|'); var name = aData[0]; var code = aData[1]; alert('Name: ' +name+ ' Code: ' +code); $.ajax({ type:"POST", url: "yourphpfile.php", data: 'name=' +name+ '&amp;code=' +code, success: function(newdata) { alert(newdata); } //END success_ajax2 }); //END ajax() #2 } //END success_ajax1 }); //END ajax() #1 }); //END mybutt.click() }); //END $(document).ready() &lt;/script&gt; &lt;/head&gt; &lt;body&gt; Email: &lt;br /&gt; &lt;input type="text" id="eml" /&gt;&lt;br /&gt; Password: &lt;br /&gt; &lt;input type="password" id="pw" /&gt;&lt;br /&gt; &lt;input type="button" id="mybutt" value="Submit"&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <hr> <p><strong>yourphpfile.php</strong></p> <pre><code>&lt;?php if (isset($_POST['email'])) { $e = $_POST['email']; $p = $_POST['pass']; $name = 'Bob'; $code = '1234'; $resp = $name .'|'. $code; echo $resp; }else if (isset($_POST['name'])) { $n = '&lt;h1&gt;Here is something new&lt;/h1&gt;'; echo $n; } </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.
