Timetable Help

Plug-in · August 6, 2011

Hello, I'm having a lot of trouble trying to achieve something. I've got a timetable that starts at the current hour and shows four more hours (current is 10 so it would shout 10, 11, 12, 1, 2) but on the sides I have arrows that change it so you can see the next five hours but even with my code to prevent it the numbers always end up above 12 or below 0 (negatives). Here is the code the displays the times:

<?php $time = $t->current(); ?>

<div id='arr_left' onclick='show(<?php echo $time-5; ?>);'><!-- Left Arrow --></div>
<div id='content'><?php echo $t->hour(0, $time); ?></div> <div id='bar'></div>
<div id='content'><?php echo $t->hour(1, $time); ?></div> <div id='bar'></div>
<div id='content'><?php echo $t->hour(2, $time); ?></div> <div id='bar'></div>
<div id='content'><?php echo $t->hour(3, $time); ?></div> <div id='bar'></div>
<div id='content'><?php echo $t->hour(4, $time); ?></div>

<div id='arr_right' onclick='show(<?php echo $time+5; ?>);'><!-- Right Arrow --></div>

If you notice the JQuery then I'll show you that at the end if there's an error in there but here is the actions.php where the classes are:

<?php
date_default_timezone_set('Australia/Perth');

class time {

function hour($num, $time) {

  $date = $time + $num;

  if (strpos($date, '-')) {
   $date = str_replace('-', '', $date);
   $date = ($date<(-13))? $date-12 . "PM" : $date . "AM";
   return $date;
   }
   else {
    $date = ($date>12) ? $date-12 . "AM" : $date . "PM";
    return $date;
   }
}

function current() {
  $dfunc = date('h');
  $date = (isset($_GET['n'])) ? $_GET['n'] : $dfunc-1+1;;
  return $date;
}

}


$t = new time;
?>

Here is the JQuery, it is linked in the <head></head> tags to the JQuery library.

<script type='text/javascript'>
        function show(date) {
         $('body').load('index.php?n=' + date);
        }
</script>

Again I would really appreciate it if you could help me
