hi,

i have implemented a calendar in php and added contols to display the previous and next months. How will I enhance my code to add links to display the previous and next year calendars?

My code is as follows:

<?php
session_start();
$_SESSION['username'];
$_SESSION['unique_id'];
$username = $_SESSION['username'];
$unique_id = $_SESSION['unique_id'];
?>

<?php
    $host = "localhost";
    $user=""; 
    $password=""; 
    $db_name=""; 
    $tbl_name=""; 
    
    $con = mysql_connect("localhost","","");
    if (!$con)
      {
          die('Could not connect: ' . mysql_error());
      }
    mysql_select_db("$db_name", $con);
    
    // Now we need to define "A DAY", which will be used later in the script:
    define("ADAY", (60*60*24));
     
    // The rest of the script will stay the same until about line 82
     
    if ((!isset($_GET['month'])) || (!isset($_GET['year']))) {
        $nowArray = getdate();
        $month = $nowArray['mon'];  //mon - Numeric representation of a month
    $year = $nowArray['year'];
    } else {
        $month = $_GET['month'];
    $year = $_GET['year'];
    }
    $start = mktime(12,0,0,$month,1,$year);
    $firstDayArray = getdate($start);
    ?>

    <form method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>" style="padding-top:50px">

$previous_year = '<a href="?month='.($year != 2011 ? $year - 1 : 2050).'&year='.($year != 2011 ? $year : $year - 1).'" class="control" style="text-decoration:none; padding-left:150px;"><<  Previous Year</a>';
