    <p>On initial page load: The process flow looks like this:</p> <blockquote> <p>Server Side code -> sends data to client -> browser begins rendering and executing JS</p> </blockquote> <p>On form Submit:</p> <blockquote> <p>Client Executes code (javascript) -> Sends data to server -> Server gets data and processes</p> </blockquote> <p>to change the way this works you would want to do an <a href="http://api.jquery.com/jQuery.ajax/" rel="nofollow">ajax</a> or <a href="http://api.jquery.com/jQuery.post/" rel="nofollow">post</a> form submit and on "success" then execute the above JavaScript. You can post to the same page or change it to a RESTful service.</p> <p>Here are examples of AJAX and POST functions from jQuery:</p> <h2>AJAX</h2> <pre><code>$.ajax({ type: "POST", url: url, data: data, success: success, dataType: dataType }); </code></pre> <h2>POST (JS)</h2> <pre><code>$.post('ajax/test.html', function(data) { $('.result').html(data); }); </code></pre> <hr> <p>Here is the <strong>result specifically for you</strong>, taking the two snippets above.</p> <h2>JavaScript/jQuery</h2> <pre><code>$(function () { if ($('form').length &gt; 0) { $('form').submit(function (e) { e.preventDefault(); $.ajax({ type: "POST", url: "YOUR-URL", data: YOUR - FORM - DATA, success: function (result) { //result will contain the xml or JSON result of calling the FORM var check = "&lt;?php echo $studentID; ?&gt;"; alert(check); if (check != "") { alert("This user already exists"); return false; } else { return true; } }, dataType: "XML-OR-JSON" }); }); } }) </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
