    <p>You could try constructing the javascript with PHP. this will allow you to load executable content instead of static. To do this, first you'll nee a javascript function to load the php into a script element. something like :-</p> <pre><code>function loadscript(src){ var myscript = document.createElement('script'); myscript.src = src; document.getElementByTagName('head')[0].appendChild(src); } </code></pre> <p>you can then write php variables to a constructed JS code then load the php by calling the function in the browser. The PHP would be somthing like this.</p> <p>on the server myphpcode.php</p> <pre><code>&lt;?php $sessionid = $_SESSION['user_id']; ?&gt; mydiv.innerHTML = 'User ID ' + &lt;?php echo $sessionid; ?&gt;; </code></pre> <p>js call in HTML page</p> <pre><code>loadscript('myphpcode.php'); </code></pre> <p>use the same method to send data back to the server via PHP by constructing a valid query string in javascript to apppend to the loadscript call.</p> <pre><code>var a = 'some data'; var b = 'some more data'; var urlstring = 'myphpcode.php?a=' + a + '&amp;b=' + b; loadscript(urlstring); </code></pre> <p>you can then store the javascript variables in a database for example by writing a function in myphpcode.php.</p> <pre><code>&lt;?php include mydbconnection.php // some database connection code if ((isset $_GET["a"]) &amp;&amp; (isset $_GET["b"])) { //check the url query string has data $a = $_GET["a"]; $b = $_GET["b"]; $query = "INSERT into mydatabase.mytable (columnA, columnB) VALUES ('" . $a . "','" . $b . "');"; if ($mysqli-&gt;prepare($query)){ $mysqli-&gt;execute(); } } ?&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.
