    <p>I came across this website and was impressed by it and wanted to try and learn how it works: <a href="http://demo.pellegrom.me/uptime/" rel="nofollow">http://demo.pellegrom.me/uptime/</a></p> <p>My attempt is here: <a href="http://www.4playtheband.co.uk/up/up.php" rel="nofollow">http://www.4playtheband.co.uk/up/up.php</a> but I have had to fade out the entire section rather than just the status'. My tooltips are also broken because they are dynamically generated - I'm sure I need to apply the <code>live</code> function but just not sure on how to do this without breaking it.</p> <p>Here is the code:</p> <p>up.php:</p> <pre><code>&lt;?php require('../db.php'); ?&gt; &lt;script type="text/javascript"&gt; $(document).ready(function(){ $("#container").load("response.php").fadeIn("slow"); setInterval(function() { $('#container').fadeOut('slow').load('response.php').fadeIn("slow"); }, 3600000); $('.icon').each(function(){ $(this).simpletip({ showEffect: 'fade', hideEffect: 'fade', fixed: 'true', position: 'right', offset:[10, 0], content: $('img',this).attr('alt') }); }); $('#check').click(function(){ $('.http-status').empty(); $('.http-status').html('&lt;img src="images/spinner.gif"/&gt;'); $('#container').fadeOut('slow').load('response.php').fadeIn("slow"); }); }); &lt;/script&gt; &lt;h2&gt;Website Checker&lt;/h2&gt; &lt;div id="container"&gt;&lt;/div&gt; &lt;br /&gt; &lt;a href="#" id="check" class="button"&gt;Check Now&lt;/a&gt; </code></pre> <p>process.php:</p> <pre><code>&lt;?php require('../db.php'); function Visit($url) { $agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";$ch=curl_init(); curl_setopt ($ch, CURLOPT_URL,$url ); curl_setopt($ch, CURLOPT_USERAGENT, $agent); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch,CURLOPT_VERBOSE,false); curl_setopt($ch, CURLOPT_TIMEOUT, 5); $page=curl_exec($ch); //echo curl_error($ch); $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); if($httpcode&gt;=200 &amp;&amp; $httpcode&lt;300) { echo '&lt;span class="up"&gt;'.$httpcode.'&lt;span class="icon"&gt;&lt;img src="images/info.png" alt="website is up"/&gt;&lt;/span&gt;&lt;/span&gt;'; } else { $httpcode=404; echo '&lt;span class="down"&gt;'.$httpcode.'&lt;span class="icon"&gt;&lt;img src="images/info.png" alt="website is down"/&gt;&lt;/span&gt;&lt;/span&gt;'; $date = date("l, j \of F Y \@ H:i"); $to = "someone@domain.com"; $subject = "Urgent: $url is down"; $message = "Hello,\n\nIt appears that on our latest check of $url on $date that the site was down.\n\nRegards,\nWeb Checker"; $headers = 'From: noreply@webchecker.co.uk' . "\r\n" . 'Reply-To: noreply@webchecker.co.uk' . "\r\n"; mail($to, $subject, $message, $headers); } } ?&gt; &lt;ul id="site-list" class="list"&gt; &lt;li class="title"&gt; &lt;span class="id"&gt;&lt;/span&gt; &lt;span class="name"&gt;Title&lt;/span&gt; &lt;span class="url"&gt;URL&lt;/span&gt; &lt;span class="status"&gt;HTTP Status&lt;/span&gt; &lt;/li&gt; &lt;?php // some PHP to fetch all the gig entries from the shows table $sql = "SELECT * FROM `check`"; $query = mysql_query($sql) or die(mysql_error()); // a loop to place all the values in the appropriate table cells while ($row = mysql_fetch_array($query)){ //begin the loop... $id=$row['id']; $name=$row['name']; $url=$row['url']; ?&gt; &lt;li&gt; &lt;span class="id"&gt;&lt;?php echo $id; ?&gt;&lt;/span&gt; &lt;span class="name"&gt;&lt;?php echo $name; ?&gt;&lt;/span&gt; &lt;span class="url"&gt;&lt;?php echo $url; ?&gt;&lt;/span&gt; &lt;span class="status http-status"&gt;&lt;?php echo Visit("$url"); ?&gt;&lt;/span&gt; &lt;/li&gt; &lt;?php } ?&gt; &lt;/ul&gt; </code></pre> <p>That's quite a lot of code, apologies if it's difficult to follow.</p> <p>Aside from the two points already mentioned, the only other thing puzzling me is how to avoid the e-mail sending when <code>container</code> is first loaded upon the page being visited?</p> <p>Thanks in advance for all help and suggestions.</p>

    2. COI don't feel like reading all that so i m just gonna ask, have you considered AJAX? In simplest terms, you can just echo back individual results and just replace content within status `.http-status` tags so everything else stays as is. I can provide details on this if you are interested.

    3. COHi Tumharyyaaden, thanks for the comment. If you are able to explain then that would be great - I know how to process forms using jquery's ajax function but I don't know how to do it in this situation since it is not a form. All I need to do is somehow refresh the data within 'http-status', i.e. to call the php function again inside that `span` element, rather than the entire section which is what I am doing at the moment.

Querying!

 
Guidance
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.

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