I have a range of numbers from 1 to 40 say that I pull from a table in my database and out put onto the screen using a while loop! with these numbers I am using a submit button which i will replace with a image button later on! Just now i can only get them in one line using a table but I want to get them into groups of say 5 or so colums and then go to next line print the next 5 or so colums! I have been trying for loops but they print out 1111, 2222, 3333, 4444, etc. in diffrent lines which is not what i want! I want,

<?     
  $q3 = "SELECT * FROM tblgame";
  $r3 = mysql_query($q3);
  while($row2 = mysql_fetch_array($r3))
  {
    $game_cost = $row2['game_cost'];      

    echo "<p>Game ID: ".$row2['game_id'];
    echo "<br>Game Day: ".$game_day;
    echo "<br>Next Game Date: ".$row2['game_date_day']."/".$row2['game_date_month']."/".$row2['game_date_year'];

    $fyear = $row2['game_date_year'];
    $fmonth = $row2['game_date_month'];
    $fday = $row2['game_date_day'];

       }
       ?>
     </td>
     <?
   }
   ?>
 </tr>
 </table>

Please help me i have been stuck on this problem for a good number of days and its driving me loopy lol!

Thank you Stephen


nested for-loops is the key:

$list=array();
while($row2 = mysql_fetch_array($r3)) $list[] = $row2;

$countList = count($list);
$cols = 5;
$rows = ceil($countList / $maxPerRow);

for ($i=0; $i<$rows; $i++) {
    echo 'opening stuff per row... <tr> or something';
    for ($j=0; $j<$rows; $j++) {
        echo 'your stuff per item... might be somthing like <td>s';
    }

    echo 'closing stuff per row... </tr> or something';
}

something like this


I'm assuming that the 'real' problem lays somewhere between <table> and </table> and that you want to put the values returned by the fourth query (for some reason mapped to $row3) in a table with 5 columns.

Using the PHP modulo operator ('%'), you could do something like this:

<?php
    $r4 = <your mysql_query>
    $i = 0;
    while ($row3 = mysql_fetch_array($r4)) {
        if ($i % 5 == 0) { // true for 0, 5, 10, ...
            echo "<tr>";
        }
        echo "<td>";
        // what you want to put between your <td> tags comes here
        echo "</td>";
        if (($i+1) % 5 == 0) { // true for 4, 9, 14, ...
            echo "</tr>";
        }
        $i++;
    }
    // if the number of rows is not a multiple of 5, we must clean up after ourselves:
    if ($i % 5 != 0) {
        echo "<td colspan=\"" + (5-($i % 5)) + "\">&nbsp;</td></tr>";
    }
?>

I haven't tested the code myself.

For the sake of clearity, please consider using proper indentation and consistent variable naming in your code. Also note that using a proper title and less exclamation marks in your question would improve the clearity of it.
