Hi,
I have a table of numbers that are loaded from the database and I need to create a totals row to show the totals for each column.

This is the code for the table:
<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td bgcolor="#000000" class="tableTextHeading">&nbsp;</td>
    <td bgcolor="#000000" class="tableTextHeading">Team</td>
    <td width="40" bgcolor="#000000" class="tableTextHeading"><div align="center">Goals</div></td>
    <td width="30" bgcolor="#000000" class="tableTextHeading"><div align="center">YC</div></td>
    <td width="30" bgcolor="#000000" class="tableTextHeading"><div align="center">RC</div></td>
    <td width="30" bgcolor="#000000" class="tableTextHeading"><div align="center">MOM</div></td>
  </tr>
          <?php do { ?>
            <tr bgcolor="<?php echo ($ac_sw1++%2==0)?"#ffffff":"#dfdfdf"; ?>" onmouseout="this.style.backgroundColor=''" onmouseover="this.style.backgroundColor=''">
              <td width="20">
              0<?php echo $i++;?>              </td>
              <td width="187"><a href="player-profile.php?id=<?php echo $row_squad_members['player_id']; ?>" class="playerStats"><?php //echo $row_squad_members['fname']; ?> <?php //echo $row_squad_members['sname']; ?> <?php echo $row_player_match['team_name']; ?></a></td>
              <td><div align="center" class="playerStats"><?php echo $row_player_match['myGoals']; ?></div></td>
              <td><div align="center" class="playerStats"><?php echo $row_player_match['myYC']; ?></div></td>
              <td><div align="center" class="playerStats"><?php echo $row_player_match['myRC']; ?></div></td>
              <td><div align="center" class="playerStats"><?php echo $row_player_match['myMOM']; ?></div></td>
            </tr>
            <?php } while ($row_player_match = mysql_fetch_assoc($player_match)); ?>
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
</table>

Use this kind of pattern.  Where you currently have this...

<?php echo $row_player_match['myGoals']; ?>

... replace it with the code snippet.
<?php 
echo $row_player_match['myGoals']; 
$total_myGoals = $total_myGoals + $row_player_match['myGoals']; 
?>

Add a new query that does something like this:

SELECT SUM(myGoals) as SumMyGoals, SUM(myYC) as SumMyYC etc etc FROM tablename WHERE conditions

and then just place SumMyGoals and SumMyYC in a new table row outside of the repeat.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Then after line 28, put in another row to present the totals you have accumulated, something like this code snippet.

HTH, ~Ray
<tr>
<td><div align="center" class="playerStats"><?php echo $total_myGoals; ?></div></td>
<td><div align="center" class="playerStats"><?php echo $total_myYC; ?></div></td>
<td><div align="center" class="playerStats"><?php echo $total_myRC; ?></div></td>
<td><div align="center" class="playerStats"><?php echo $total_myMOM; ?></div></td>
</tr>

SVN-Blame: Distracted by barking dog.  

But seriously, since we already have all the data we don't need another query.  I think either way will work fine.

best to all, ~Ray

Agreed, either method works but Ray's is more elegant and he beat me by nanoseconds to the post (hence the tiny fist shaking)

There's a small bug in a new closing process and that's why you had "trouble"

It would have closed on its own in four days with points to Ray as intended.
