<p>I am creating an online exam page for my project. I have a countdown timer, but it resets on page refresh. How can I make it not to reset? The timer is set by fetching time from db. I am using php mysql. Please help me. Here is my code.</p> <pre><code><?php $result=mysql_query("select * from test where testid='29'"); while($time=mysql_fetch_array($result)){ $dateFormat = "d F Y -- g:i a"; $targetDate = time() + ($time['duration']*60); $actualDate = time(); $secondsDiff = $targetDate - $actualDate; $remainingDay = floor($secondsDiff/60/60/24); $remainingHour = floor(($secondsDiff-($remainingDay*60*60*24))/60/60); $remainingMinutes = floor(($secondsDiff-($remainingDay*60*60*24)-($remainingHour*60*60))/60); $remainingSeconds = floor(($secondsDiff-($remainingDay*60*60*24)-($remainingHour*60*60))-($remainingMinutes*60)); $actualDateDisplay = date($dateFormat,$actualDate); $targetDateDisplay = date($dateFormat,$targetDate); } ?> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript"> var days = <?php echo $remainingDay; ?> var hours = <?php echo $remainingHour; ?> var minutes = <?php echo $remainingMinutes; ?> var seconds = <?php echo $remainingSeconds; ?> function setCountDown () { seconds--; if (seconds < 0){ minutes--; seconds = 59 } if (minutes < 0){ hours--; minutes = 59 } if (hours < 0){ hours = 23 } document.getElementById("remain").innerHTML = " "+hours+" hr "+minutes+" min "+seconds+" sec"; SD=window.setTimeout( "setCountDown()", 1000 ); if (minutes == '00' && seconds == '00') { seconds = "00"; window.clearTimeout(SD); window.location = "result.php" } } </script> </head> <body onLoad="setCountDown();"> <div id="remain"> <?php echo "$remainingHour hours, $remainingMinutes minutes, $remainingSeconds seconds";?> </div> </code></pre>

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.
