UNIXTIME PROBLEM

I had this 'if else' statement which calls a function depending on whether a location or a date has been chosen from drop downs. The database has a field called 'depart_time' ie which is entered as UNIXTIME and has two rows, one for outward departure, and one for inward departure (flights) ie only their chronological difference indicates which. Although my solution for the location SQL query seems to have sorted the dates error, when searching by location, I can't figure out if I can alter my dates SQL to correct the problem when searching by month/year, or whether I should be looking elsewhere. BTW I'm fairly new to php/mySQL and this is me trying to correct someone elses code.

See: [a href=\"http://www.travelforthearts.co.uk/shtml/master_detail.php?type=3&month=03&year=2006\" target=\"_blank\"]http://www.travelforthearts.co.uk/shtml/ma...th=03&year=2006[/a]
where the 11th comes before the 8th.

[b]OLD CODE[/b]
[code]    

<?php
                          if($_GET['location'] && $_GET['type'])
                          {
                              $tours = $_TOURS->get_tours_by_location($_GET['type'],$_GET['location']);
                          }    
                          elseif($_GET['month'] && $_GET['year'])
                          {
                              $tours = $_TOURS->get_tours_by_date($_GET['type'],$_GET['month'],$_GET['year']);
                          }                          
                          
                          if(is_array($tours))
                          {
                              foreach($tours as $key => $data)
                              {?>
                          <tr bgcolor="#FFFFFF" class="bodycopywht">
                            <td valign="top"><span class="style14"><a href="master_result.php?tid=<?php echo $data['tour_id']?>"><?php echo $data['tour_name'];?></a></span><span class="style6"><br>
                              </span></td>
                            <td align="center" valign="top" class="style14"><?php echo $data['day'].'/'.$data['month'].'/'.$data['year'];?></td>
                          </tr>
                          <?}
                          }?>
[/code]

[b]This was the old function for location:[/b]

[code]
function get_tours_by_location($type,$location)
{
    $SQL = 'SELECT tour.*,
    performances.performance_id,
    venues.venue_id,
    FROM_UNIXTIME(flights.depart_time,"%d") AS day,
    FROM_UNIXTIME(flights.depart_time,"%m") AS month,
    FROM_UNIXTIME(flights.depart_time,"%Y") AS year
    FROM tour
    LEFT JOIN performances ON performances.tour_id = tour.tour_id
    LEFT JOIN venues on performances.venue_id = venues.venue_id
    LEFT JOIN flights on flights.tour_id = tour.tour_id
    WHERE tour.tour_type LIKE("%'.$type.'%") AND venues.venue_location = "'.$location.'"
    GROUP BY tour.tour_id, venues.venue_location
    ORDER BY flights.depart_time ASC';

[/code]

... and this for date

[code]
function get_tours_by_date($type,$month,$year)
{
    $SQL = 'SELECT tour.*,
    performances.performance_id,
    venues.venue_id,
    FROM_UNIXTIME(flights.depart_time,"%d") AS day,
    FROM_UNIXTIME(flights.depart_time,"%m") AS month,
    FROM_UNIXTIME(flights.depart_time,"%Y") AS year
    FROM tour
    LEFT JOIN performances ON performances.tour_id = tour.tour_id
    LEFT JOIN venues on performances.venue_id = venues.venue_id
    LEFT JOIN flights on flights.tour_id = tour.tour_id
    WHERE tour.tour_type LIKE("%'.$type.'%") AND FROM_UNIXTIME(flights.depart_time,"%m") = "'.$month.'" AND     FROM_UNIXTIME(flights.depart_time,"%Y") = "'.$year.'"
    GROUP BY tour.tour_id, venues.venue_location
    ORDER BY flights.depart_time ASC';
[/code]

[b]unfortunately it was returning the dates on the results page in the wrong order in some searches, so I changed the if else too:[/b]

[code]

   <?php
                          if($_GET['location'] && $_GET['type'])
                          {
                              $tours = $_TOURS->get_tours_by_location($_GET['type'],$_GET['location']);
                          }    
                          elseif($_GET['month'] && $_GET['year'])
                          {
                              $tours = $_TOURS->get_tours_by_date($_GET['type'],$_GET['month'],$_GET['year']);
                          }                          
                          
                          
                          if(is_array($tours))
                          {
                              foreach($tours as $key => $data)
                              {?>
                          <tr bgcolor="#FFFFFF" class="bodycopywht">
                            <td valign="top"><span class="style14"><a href="master_result.php?tid=<?php echo $data['tour_id']?>"><?php echo $data['tour_name'];?></a></span><span class="style6"><br>
                              </span></td>
                            <td align="left" valign="top" class="style14"> <?php echo $data['day']?></td>
                          </tr>
                          <?}
                          }?>

[/code]

[b]and the functions to:[/b]
[code]

function get_tours_by_location($type,$location)
{
    $SQL = 'SELECT tour.*,
    performances.performance_id,
    venues.venue_id,
    DATE_FORMAT(MIN(FROM_UNIXTIME(flights.depart_time)),"%D %b %Y") AS day
    FROM tour
    LEFT JOIN performances ON performances.tour_id = tour.tour_id
    LEFT JOIN venues on performances.venue_id = venues.venue_id
    LEFT JOIN flights on flights.tour_id = tour.tour_id
    WHERE tour.tour_type LIKE("%'.$type.'%") AND venues.venue_location = "'.$location.'"
    GROUP BY tour.tour_id, venues.venue_location
    ORDER BY flights.depart_time ASC';
[/code]

and:

[code]

function get_tours_by_date($type,$month,$year)
{
    $SQL = 'SELECT tour.*,
    performances.performance_id,
    venues.venue_id,
    DATE_FORMAT(MIN(FROM_UNIXTIME(flights.depart_time)),"%D %b %Y") AS day
    FROM tour
    LEFT JOIN performances ON performances.tour_id = tour.tour_id
    LEFT JOIN venues on performances.venue_id = venues.venue_id
    LEFT JOIN flights on flights.tour_id = tour.tour_id
    WHERE tour.tour_type LIKE("%'.$type.'%")
    AND FROM_UNIXTIME(flights.depart_time,"%m") = "'.$month.'"
    AND FROM_UNIXTIME(flights.depart_time,"%Y") = "'.$year.'"
    GROUP BY tour.tour_id, venues.venue_location
    ORDER BY flights.depart_time ASC';

[/code]

[b]...which as I say sorted the location searches, but not the date searches[/b]
