Question

I’ve tried to make this work for 24 hours now, and now it feels like I’m close to it!

I would like to get date (column:datum) and location (column:plats) from MySQL, where my code looks like:

<?php

$sql = "SELECT datum FROM gigs GROUP BY DATE_FORMAT( datum, '%Y' ) ORDER BY datum DESC";
$result = mysql_query($sql);

 while($r = mysql_fetch_array($result)) {

  $date = $r['datum'];
  $date_new = new DateTime($date);
  $year = $date_new->format('Y');
  $month = $date_new->format('M');
  $day = $date_new->format('d');

  $sql2 = "SELECT * FROM gigs WHERE DATE_FORMAT( datum, '%Y' ) = $year ORDER BY datum ASC";
  $result2 = mysql_query($sql2);

  echo "<tr height=20px><td></td><td align=center><b>".$year."</b></td></tr>";

  echo "<tr><td><b>".$month."</b></td></tr>";

  while($r2 = mysql_fetch_array($result2)) {

   $date2 = $r2['datum'];
   $date_new2 = new DateTime($date2);
   $year2 = $date_new2->format('Y');
   $month2 = $date_new2->format('M');
   $day2 = $date_new2->format('j');

 //echo "<b>Month: ".$month."</b>";
 //echo "<b>Month2: ".$month2."</b>";

    if($month != $month2) {
     echo "<tr><td>&nbsp;</td></tr><tr><td><b>".$month2."</b></td></tr>";
    }

    $month = $month2;

    echo "<tr class=giglist><td>".$day2."</td><td>".$r2['plats']."</td></tr>"; 



  }
    echo "</td></tr>";
 }

?>

This gives me:

2011
Jan
1. Location
2. Location
3. Location
...

Feb
1. Location
2. Location
3. Location
...
...
Dec
1. Location
2. Location
3. Location
...

2010
Dec

Jan
1. Location
2. Location
3. Location
...
Feb
1. Location
2. Location
3. Location
...
...
Dec
1. Location
2. Location
3. Location
...

I do NOT want the extra December written under “2010”…

I hope someone can help, cause I’m lost in my own code xD thanks!

Your code is to much complicated, you can do that with only one query, see this code

<?php 
$sql = 'SELECT
            *, 
            DATE_FORMAT( datum, "%Y" ) "year", 
            DATE_FORMAT( datum, "%M" ) "month", 
            DATE_FORMAT( datum, "%e" ) "day" 
        FROM gigs
        ORDER BY year DESC, month DESC, day ASC';

$year = null;
$month = null;
$stmt = mysql_query($sql);
while($row = mysql_fetch_array($result)) {
    if ($year != $result['year']) {
        // Year changed
        $year = $result['year'];
        echo "<tr height=20px><td></td><td align=center><b>".$year."</b></td></tr>";
    }
    if ($month != $result['month']) {
        // Month changed
        $month = $result['month'];
        echo "<tr><td>&nbsp;</td></tr><tr><td><b>".$month."</b></td></tr>";
    }
    echo "<tr class=giglist><td>".$result['day']."</td><td>".$row['plats']."</td></tr>"; 
}
