Reply To: Repeater sub field display by group based on value

I was trying to do the same thing a while ago. Couldn’t figure out how to do it natively in ACF so I just made a normal PHP array, sorted it, then looped through it.

Full credit to the following (my solution is basically these stuck together):

<?php

// check if the repeater field has rows of data
if( have_rows('person_repeater') ):

    $personArray = get_field('person_repeater');

    function callback( $a, $b ) {

        if ( $a['person_group'] > $b['person_group'] ) {

            return 1;

        } else if ( $a['person_group'] < $b['person_group'] ) {

            return -1;

        }

        return 0;

    }

    uasort( $personArray, 'callback' );

    foreach ($personArray as $person) {

        ?>

        Group name: <?php echo $person['person_group']; ?>, Person Name: <?php echo $person['person_name']; ?><br>

    <?php

    }

else :

    // no rows found

endif;

?>
