    <p>I don't exactly understand why so complicated call of ajax and parsing of value from serverpage, but maybe You have one JS code for more than one edit function at more places... But to the point:</p> <p>It looks like You don't have Your <code>&lt;div id="editpersoneelform"&gt;&lt;/div&gt;</code> inside the HTML from where the AJAX is called...</p> <p>Lets suppose You have similar HTML file (I recommend using of jQuery at least for working with elements when You need the AJAX to be called in raw way):</p> <pre><code>&lt;div id="editpersoneelform"&gt;&lt;/div&gt; &lt;div class="jbutton"&gt; &lt;a onclick="edit(\'editpersoneel.php\',\''.$b['id'].'\')"&gt;Adjust&lt;/a&gt; &lt;/div&gt; &lt;script type="text/javascript"&gt; function edit(serverpage, persoonid) { $(".opendg").dialog({ open:function () { $(this).load('/location/php/' + serverpage); }, title: 'Change!', autoOpen: true, closeOnEscape: true, height: 335, width: 650, modal: true, resizable: false, close: function(){}, buttons: { "Change": function() { sendedit(serverpage, persoonid); return; }, "Cancel": function() { $(this).dialog("close"); } } }); xmlhttp = ajaxFunction(); if (xmlhttp) { var url = "/location/php/" + serverpage; var pagelength = serverpage.length; var value = serverpage.substr(0,pagelength - 4); var params = "edit=" + value + "&amp;id=" + persoonid; xmlhttp.open("POST", url, true); xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", params.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.onreadystatechange = function() { if(xmlhttp.readyState == 4 &amp;&amp; xmlhttp.status == 200) { if(xmlhttp.responseText != '') { value = value + 'form'; alert(value); $('div#'+value).html(xmlhttp.responseText); } } } xmlhttp.send(params); } } &lt;/script&gt; </code></pre> <p>and then You have Your PHP file that is called by AJAX:</p> <pre><code>&lt;?php if($_POST['edit'] == 'editpersoneel') { //Query run here to get the results $form = '&lt;form&gt; &lt;table&gt; &lt;tr&gt; &lt;td class="first"&gt;Location: &lt;/td&gt; &lt;td&gt;&lt;input type="text" value="'.$result['location'].'" /&gt;&lt;/td&gt; &lt;td class="first"&gt;phonenumber&lt;/td&gt; &lt;td&gt;&lt;input type="text" value= "'.$result[phonenumber'].'" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt;'; echo $form; } ?&gt; </code></pre> <p>If You want to load AJAX response to a certain element, that element has to be recent in the code from where the AJAX is called.</p> <p>Try this and let us know if You'd succeeded.</p>

    1. COThanks for your help, but I didn't got it worked. Still same issues. Also <div id="editpersoneelform"></div> is on a different page then <div class="jbutton"> <a onclick="edit(\'editpersoneel.php\',\''.$b['id'].'\')">Adjust</a> </div> The first div is on editpersoneel.php and the second (with the call) is on personeel.php

    2. COYes, and that is what I point out - the <div id="editpersoneelform"></div> must be on the same page where the AJAX call (so <a onclick=...>) is...

    3. COI tried putting it on the same page, just as your code implied, but couldn't get it work. I'll try a few things more with your example, I'll let you know.

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).
