    <p>You can try to correct somme errors first, as it's difficult to see PHP script errors when called with AJAX.</p> <p>As all records are in a single form, we must identify each record individually like "<strong>user-field123-updated</strong>":</p> <p>js:</p> <pre><code>$(".listen").keyup(function() { var myname = $(this).attr("name"); if(! myname.match(/updated/i)) { $(this).attr("name", myname + "-updated"); } }) </code></pre> <p>HTML while () {} loop, user name will be identified by user-field123:</p> <pre><code>&lt;form action="post"&gt; &lt;?php while($rows=mysql_fetch_array($result)) { ?&gt; &lt;tr&gt; &lt;td&gt;Whatever this row name is: &lt;?php echo $rows['Name']; ?&gt; &lt;input type="hidden" name="ID" value="&lt;?php echo $rows['ID']; ?&gt;&lt;/td&gt; &lt;td&gt;The editable field: &lt;input class="listen" type="text" name="user-field&lt;?php echo $rows['ID']; ?&gt;" size="4" value="&lt;?php echo $rows['Users']; ?&gt;"&gt;&lt;/input&gt;&lt;/td&gt; &lt;/tr&gt; &lt;?php } ?&gt; &lt;input type="submit" name="submit-button" value="Click to update only fields I changed"&gt;&lt;/input&gt; &lt;/form&gt; </code></pre> <p>PHP to save in DB, syntax:</p> <pre><code>// // Users table $tbl_name must be set before: // if(isset($_POST['submit-button'])) { // // IDs is an array: // $IDs = $_POST['ID']; foreach($IDs as $ID) { if(isset($_POST['user-field' . $ID .

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).
