    <p>I'm quite a beginner in ajax technology. I have a php for execute a mysql_query and I would like to use the result on the client side.</p> <p>My <code>database.php</code>:</p> <pre><code>$q=mysql_query("SELECT name FROM customers"); $res=mysql_fetch_array($q); echo json_encode($res); </code></pre> <p>and my <code>client.php</code></p> <pre><code>&lt;div id="output"&gt;this element will be accessed by jquery and this text replaced &lt;/div&gt; &lt;script id="source" language="javascript" type="text/javascript"&gt; $(function () { $.ajax({ url: 'database.php', //the script to call to get data data: "", dataType: 'json', //data format success: function(data) //on recieve of reply { var name = data[0]; $('#output').html("&lt;b&gt;id: &lt;/b&gt;"+name); } }); }); &lt;/script&gt; </code></pre> <p>This is from some tutorial I've found. And as I saw the <code>database.php</code> works. It prints right data, but in the <code>client.php</code> I can't get anything. What could be the problem?</p> <p>---------EDITED---------</p> <p>So, seems like on the web server runs php 4.4.7 and looks like json_encode() function does not wokrs because of that. I' ve found a "solution". I include upgrade.php, which implemets new methods for older versions of php, as far as i understands. here is the webste of it <a href="http://include-once.org/p/upgradephp/" rel="nofollow">http://include-once.org/p/upgradephp/</a></p> <p>I can't upgrade php version so could this be a good solution? At the moment it does not works</p>

    1. COcould you check the value of `data` inside the callback? what if you also define an `error` callback so you can check for errors?

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.
