Ordering by a selected column from database - php

Question

I have the following table that is meant to show a win/loss record and to have rankings. I'm running into two issues with it though.
First issue is that my rank <td> is not progressing like I want it to. What I mean by that is for each record that is looped and output, I want it to be numbered for.
i.e.:
1
2
3, etc.
The second part I cannot figure out is I want the person with the highest win total to be ranked the highest. I also want losses to be configured into that. So if someone is 5-0, their rank will be higher than someone's that is 5-1.
Could someone point me in the right direction with these issues I am running into?
<h2>Division 1</h2>
<table>
<tr>
<th>Rank</th>
<th>Name</th>
<th>Wins</th>
<th>Losses</th>
</tr>
<?php
try {
//Prepare
if ($stmt = $con->prepare("SELECT * FROM team_rankings WHERE `division`=1")) {
$stmt->execute();
$stmt->bind_result($ranking_id, $ranking_user_id, $ranking_firstname, $ranking_username, $ranking_division, $ranking_wins, $ranking_losses);
//var_dump($stmt);
if (!$stmt) {
throw new Exception($con->error);
}
$stmt->store_result();
while ($row = $stmt->fetch()) {
?>
<tr>
<td>1</td>
<td><?php echo $ranking_firstname; ?></td>
<td><?php echo $ranking_wins; ?></td>
<td><?php echo $ranking_losses; ?></td>
</table>
<?php
}
} else {
echo "<p>There aren't any players in division 1 yet.</p>";
}
}
catch (Exception $e)
{
echo "Error: " . $e->getMessage();
}
?>

Answer 1

You need to use ORDER BY like this
Do this:
SELECT * FROM team_rankings WHERE `division`=1" ORDER BY Wins DESC, Losses

For your first question you </table> needs to be out of your php while loop. Also have a counter which you can increment and show the order.
$count = 0;
while ($row = $stmt->fetch()) {
?>
<tr>
<td><php echo $count; $count++; ?></td>
<td><?php echo $ranking_firstname; ?></td>
<td><?php echo $ranking_wins; ?></td>
<td><?php echo $ranking_losses; ?></td>
</tr>
<?php } ?>
</table>
Something better? Use foreach

Answer 2

The numbering issue can be resolved as such:
$i = 1;
while ($row = $stmt->fetch()) {
?>
<tr>
<td><?php echo $i ?></td>
<td><?php echo $ranking_firstname; ?></td>
<td><?php echo $ranking_wins; ?></td>
<td><?php echo $ranking_losses; ?></td>
</tr>
<?php
$i++;
}
This sets a variable $i to '1' (outside the loop), echos the variable as the number in your <td>, and increments the variable $i++ before the loop is closed.
Oh yeah, and don't close your <table> inside the loop. :)

Answer 3

Looks like you want to use the ORDER BY clause in your query. It can sort by a column directly or by some calculation. For example, you could do:
SELECT *
FROM team_rankings
WHERE division = 1
ORDER BY
(wins - losses) DESC,
wins DESC
This way 1-0 would be ranked higher than 6-6 but lower than 2-1. How appropriate this is is up to you to decide.
