获取 user_id 记录并计算列

Question

Basically I have a table with dozens of records, inside I have the wordpress user_id and some columns with stats.

I need to get all the records, combine all user data and show like a rank table.

table example of how I'm storing it:

2 (wordpress user_id) / 2 / 4 / 1
3 / 4 / 1 / 2
2 / 1 / 3 / 0

I'm getting the results: $result = $wpdb->get_results("SELECT * FROM wp7s_g_stats");

And I'm printing in a table:

<?php $i = 1; foreach($result as $column){ ?>
    <tr>
        <td><?php echo $i++."º"; ?></td>
        <td><?php $username = get_user_by( 'id', $column->stats_user_id ); echo $username->display_name; ?></td>
        <td><?php echo $column->stats_sales;?></td>
        <td><?php echo $column->stats_refunds;?></td>
        <td><?php echo $column->stats_cancellations;?></td>
    </tr>
<?php } ?>

How I want to show, where is order by sales:

Rank 1º / username 3 / 4 / 1 / 2
Rank 2º / username 2 / 3 / 7 / 1

Can someone please advise?

Answer 1

If the rest of the code is correct, which I did not test, and your model is correct, then it should be enough to sort your results by stats_sales to obtain the ranking:

$stats = $wpdb->get_results("SELECT * FROM wp7s_g_stats ORDER BY stats_sales DESC"); 

BTW, I think that $column as a variable name is confusing. Maybe $user_stat would be more fitting

<?php $i = 1; foreach($stats as $user_stat){ ?>
    <tr>
        <td><?php echo $i++."º"; ?></td>
        <td><?php $username = get_user_by( 'id', $user_stat->stats_user_id ); echo $username->display_name; ?></td>
        <td><?php echo $user_stat->stats_sales;?></td>
        <td><?php echo $user_stat->stats_refunds;?></td>
        <td><?php echo $user_stat->stats_cancellations;?></td>
    </tr>
<?php } ?>
