Calendar problem???

[cturner]

My calendar code does not display the next or previous month by clicking on the next and previous links. Can someone please look at my code that is below and tell me why this happening? Thanks in advance.

[code=php:0]
//This gets today's date
$date = time();

//This puts the day, month, and year in seperate variables
$day = date('d', $date);
$month = date('m', $date);
$year = date('Y', $date);

//Here we generate the first day of the month
$first_day = mktime(0,0,0,$month, 1, $year);

//This gets us the month name
$title = date('F', $first_day);

//Here we find out what day of the week the first day of the month falls on
$day_of_week = date('D', $first_day);

//Once we know what day of the week it falls on, we know how many blank days occure before it. If the first day of the week is a Sunday then it would be zero
switch($day_of_week){
case "Sun": $blank = 0; break;
case "Mon": $blank = 1; break;
case "Tue": $blank = 2; break;
case "Wed": $blank = 3; break;
case "Thu": $blank = 4; break;
case "Fri": $blank = 5; break;
case "Sat": $blank = 6; break;
}

//We then determine how many days are in the current month
$days_in_month = cal_days_in_month(0, $month, $year);

// next and previous links
$previous_link = "<a href=\"".$_SERVER['PHP_SELF']."?date=";
if ($month == 1) {
$previous_link .= mktime(0,0,0,12,$day,($year-1));
} else {
  $previous_link .= mktime(0,0,0,($month -1),$day,$year);
}
$previous_link .= "\"><< Prev</a>";

$next_link = "<a href=\"".$_SERVER['PHP_SELF']."?date=";
if($month == 12){
  $next_link .= mktime(0,0,0,1,$day,($year + 1));
} else {
  $next_link .= mktime(0,0,0,($month +1),$day,$year);
}
$next_link .= "\">Next >></a>";

//Here we start building the table heads
echo "<table border=1 width=294>";
echo "<tr><th colspan=7>$previous_link $title $year $next_link</th></tr>";
echo "<tr><td width=42>S</td><td width=42>M</td><td width=42>T</td><td width=42>W</td><td width=42>T</td><td width=42>F</td><td width=42>S</td></tr>";

//This counts the days in the week, up to 7
$day_count = 1;

echo "<tr>";
//first we take care of those blank days
while ( $blank > 0 )
{
echo "<td></td>";
$blank = $blank-1;
$day_count++;
}

//sets the first day of the month to 1
$day_num = 1;

//count up the days, until we've done all of them in the month
while ( $day_num <= $days_in_month )
{
echo "<td><a href=booked.php?entry_date=$day_num&entry_month=$title>$day_num</a></td>";
$day_num++;
$day_count++;

//Make sure we start a new row every week
if ($day_count > 7)
{
echo "</tr><tr>";
$day_count = 1;
}
}

//Finally we finish out the table with some blank details if needed
while ( $day_count >1 && $day_count <=7 )
{
echo "<td> </td>";
$day_count++;
}

echo "</tr></table>";

Simple, you have hard coded the values for $date at the top of the script to be todays date. You are not utilizing the value passed in the link.

Set $date using this:

$date = (isset($_GET['date']))?$_GET['date']:time();
