    <p>Change this code:</p> <pre><code>jQuery('form').ajaxForm({ target: '#noteReturn', success: function() { $('#noteReturn').fadeIn('slow'); } }); </code></pre> <p>To this:</p> <pre><code>jQuery('form').ajaxForm({ target: '#noteReturn', dataType: 'json', success: function(data) { $('#noteReturn' + data.id).html(data.note).fadeIn('slow'); } }); </code></pre> <p>And this code:</p> <pre><code>&lt;?php $note = $_POST['note']; $id = $_POST['bid']; $sql = "INSERT INTO notes (business_id, notes) VALUES ('$id', '$note')"; $result = mysql_query( $sql ); if($result) { echo " $note"; } ?&gt; </code></pre> <p>To this:</p> <pre><code>&lt;?php $note = mysql_real_escape_string($_POST['note']); $id = mysql_real_escape_string($_POST['bid']); $sql = "INSERT INTO notes (business_id, notes) VALUES ('$id', '$note')"; $result = mysql_query( $sql ); if($result) { print json_encode(array("id" =&gt; $id, "note" =&gt; $note)); } ?&gt; </code></pre> <h2>What happened?</h2> <p>The change to the PHP code is making use of PHP's <a href="http://us3.php.net/json_encode" rel="nofollow noreferrer"><code>json_encode</code></a> function to print out the id of the business to which the note was added as well as the actual note text. In the javascript code, I added the <code>dataType</code> of 'json' to tell the script what format of response to expect. Once the request is received in the <code>success</code> callback, the <code>data</code> variable is an object with the values we passed through <code>json_encode</code>. So <code>data.id</code> has the business id and <code>data.note</code> has the new note. Using jQuery's <a href="http://docs.jquery.com/Attributes/html" rel="nofollow noreferrer"><code>html()</code></a> manipulation function, the inner html of the div is updated to the latest note. The div selector uses the id we passed, so we can update the corresponding div.</p> <p>Also, this is slightly off topic, but make sure you always use <a href="http://us2.php.net/mysql_real_escape_string" rel="nofollow noreferrer"><code>mysql_real_escape_string</code></a> when putting values into a query like you are. If you do not use this, your queries will be vulnerable and susceptible to injection attacks, and they are not pretty. If a customer decided to enter a note value of <code>');DROP TABLE businesses;</code> you'd really feel the pain. Preferably, switch to <a href="http://us.php.net/pdo" rel="nofollow noreferrer"><code>PDO</code></a> or <a href="http://us.php.net/mysqli" rel="nofollow noreferrer"><code>MySQLi</code></a> and use <a href="http://us.php.net/manual/en/pdo.prepared-statements.php" rel="nofollow noreferrer"><code>prepared statements</code></a>, as they are the 'correct' way of doing queries nowadays.</p>

    1. COThis is exactly what I was looking for, Thank you Paolo. I think that is the most comprehensive answer to a coding question that I have ever received. Solid. The code that I posted was edited so that it it was easier to read, but irl the code has mysql_real_escape_string implented.

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.
