Hi - I have a calendar that is changing the days, and finding the first day ok when next or prev is clicked on, but it doesn't change the heading to reflect the new month.  Does anyone have a hint for me?  I'm stuck and can't think where to go next.  thanks.  My code is below:

 

<?php

 

  $year =  date("Y");    // current year - 2008

  $mo = date("F");        // September for September

 

  if (isset($_GET['month']))

    $month = $_GET['month'];

  else

    $month = date("n");  // 9 for September

 

    print ("<html>\n");

    print ("<head>\n");

    print ("<title></title>\n");

    print ("</head>\n");

    print ("<body>\n");

      // Output to HTML table (frame in grey)

      print ("<table style='border:1px solid grey' width='350' cellspacing='0' align='center'>\n");

          print ("<tr>\r\n");  // PREV and NEXT rows

    // First get the previous month

            $prevMonth = $month - 1; 

    print ("<td><a href='a2.php?month=$prevMonth&year=$year'>PREV</a></td>\n");

    // blank spaces for between PREV and NEXT

            print ("<td colspan='5'> </td>\n");

    // Then get the next month

    $nextMonth = $month + 1;

    print ("<td><a href='a2.php?month=$nextMonth&year=$year'>NEXT</a></td>\n");

          print ("</tr>\n");

          print ("<tr>\n");  // Month and year row

            print ("<th colspan='7'><h2>$mo $year</h2></th>\n");

    //echo "<a href='", $_SERVER['SCRIPT_NAME'], $month+1, "'>", "Next</a>\n";

          print ("</tr>\r\n");

  print ("<tr>\r\n");  // horizontal line

            print ("<td colspan='7' ><hr /></td>");

          print ("</tr>\r\n");

          print ("<tr style='background:lightgrey;'>\r\n");  // day initials

            print ("<td width='50' align='center'>S</td>\n");

    print ("<td width='50' align='center'>M</td>\n");

    print ("<td width='50' align='center'>T</td>\n");

    print ("<td width='50' align='center'>W</td>\n");

    print ("<td width='50' align='center'>T</td>\n");

            print ("<td width='50' align='center'>F</td>\n");

            print ("<td width='50' align='center'>S</td>\n");

          print ("</tr>\r\n");

  print "<tr>\n";

    $date = mktime(12, 0, 0, $month, 1, $year);

            $daysInMonth = date("t", $date);

            // calculate position of the first day in the calendar (sunday = 1st)

            $firstDay = date("w", $date);

            $rows = 1;

   

    // blank tds before first day

    for($blanktd = 1; $blanktd <= $firstDay; $blanktd++)

            {

              print "<td></td>";

            }

           

            for($day = 1; $day <= $daysInMonth; $day++)

            {

              if( ($day + $firstDay - 1) % 7 == 0 && $day != 1)

                {

                    print "</tr>\n\t<tr>";

                    $rows++;

                }

             

              print "<td align='center'>" . $day . "</td>";

            }

   

          print "</tr>\n";

   

    print ("</table>\n");

 

 

  print ("</body>\r\n");

  print ("</html>\r\n");

 

  ?>
