Question

Let’s say I have this loop in my header.php:

<div id="top-20">
    <h2 class="top-20-title">TOP 20 TEAMS</h2>

    <div class="top-20-content">

        <?php
            $params = array(
               'limit'   => -1 // get everything
            );

            $matches = pods( 'matches', $params );

            if ( 0 < $matches->total() ) {
                while ( $matches->fetch() ) {
            ?>

                 <?php echo $matches->field( 'winner_team' ); ?>
                 <br>

            <?php
                    } // end of while loop
                } // end of if any exists
            ?>

    </div><!-- /top-20-content -->  
</div><!-- /top-20 -->  

And this is what my simplified table looks like:

id | team_1 | team_2 | winner_team
--------------------------------
1  | 3      | 15     | 3
--------------------------------
2  | 20     | 8      | 8
--------------------------------
3  | 18     | 11     | 18
--------------------------------
4  | 8      | 7      | 8
--------------------------------
...

But I want instead of echoing inside while loop like

<?php echo $matches->field( 'winner_team' ); ?>

create a new array i.e. $matches_array which will contain 2 columns like id_new and winner_team_new and save the value of winner_team in winner_team_new instead of echoing it directly inside while loop.

Then I would like to loop this new created array $matches_array inside another while loop after groupby occurrences of winner_team_new and orderby them DESC.

So, I will get something like this:

8
3
18

instead of what I am currently getting when using echo in while loop:

3
8
18
8

Why I can not just do it inside sql? I need to be done using another array not using conditions in $params or sql array due to this bug: https://github.com/pods-framework/pods/issues/595 and the fact that pods framework is too complicated for my to make my own code adjustements into core so I would like to bypass this by working with an array that will be created from while loop.

So, what I need is to create an array and rearange the results based on occurrences of winner_team from the most to the less.

I have tried using

$matches_array = array_count_values(array_map($matches,array_keys($new_row)));

And then loop it in while loop but it is not working at all.

I need help with the count array/group by part.

I don’t know practically anything about it.

I just guess that I need after grouping based on the same winner_team field create a new field e.g. wins where the number of occurrences for every team(based on winner_team) value will be stored. And then order that new array DESC.

Btw. all columns in the table are INTEGERS

EDIT 2:
I have figured out how to store values from the while loop inside a new array called $matches_array and the code looks like this:

<div id="top-20">
    <h2 class="top-20-title">TOP 20 TEAMS</h2>

    <div class="top-20-content">

        <?php
            $params = array(
               'limit'   => -1 // get everything
            );

            $matches = pods( 'matches', $params );

            if ( 0 < $matches->total() ) {
                while ( $matches->fetch() ) {
            ?>

                 <?php // echo $matches->field( 'winner_team' ); ?>
                      <?php $row_array = $matches->field( 'winner_team' ); ?>
                      <?php $matches_array[]; ?>

                 <br>

            <?php
                    } // end of while loop
                } // end of if any exists
            ?>

    </div><!-- /top-20-content -->  
</div><!-- /top-20 -->

Now, I need probably do a foreach loop after a groupby(based on occureces of the numbers in winner_team field) and order the result before the output DESC.

Any advice how to do that?

The issue that initially kept you from sorting by an aliased column should be resolved. I’ve tested it with the initial scenario and it’s doing exactly what it should. I think you can happily discard this attempted work-around.
