I’m trying to reverse a repeater field I have that contains track listings. How can I get the subfield to display?

if( have_rows('track_listing') ):

  $tracks_forward = get_field('track_listing');
  $tracks_reversed = array_reverse($tracks_forward);

  foreach ($tracks_reversed as $track):
    the_sub_field('track_artist');
  endforeach;

endif;

Thanks.

As per ”, I should have done the following code works…

<?php

// Define custom query parameters
$custom_query_args = array (
	'post_type'              => array( 'post' ),
	'category_name'          => 'thebigshow',
	'pagination'             => false,
	'posts_per_page'         => '-1',
	'order'                  => 'DESC',
);

// Instantiate custom query
$custom_query = new WP_Query( $custom_query_args );

// Output custom query loop
if ( $custom_query->have_posts() ) :

	$track_number = 0;
	echo '<table class="sortable">';

		echo '<tr>';
		echo '<th>ID</th>';
		echo '<th>Artist</th>';
		echo '<th>Track</th>';
		echo '<th>Date</th>';
        echo '<tr>';

    while ( $custom_query->have_posts() ) :
        $custom_query->the_post();

        if( have_rows('track_listing') ):

        	$tracks_forward = get_field('track_listing');
			$tracks_reversed = array_reverse($tracks_forward);

			 	// loop through the rows of data
			    foreach ($tracks_reversed as $track):

			    	$track_number = $track_number+1;

			    	echo '<tr>';

			        // display a sub field value
			    	echo '<td class="track_number">';
			        echo $track_number;
			        echo '</td>';

			        echo '<td>';
			        echo $track['track_artist'];
			        echo '</td>';

					echo '<td>';
			        echo $track['track_title'];
			        echo '</td>';

			        echo '<td>';
			        echo get_post_time('jS M Y');
			        echo '</td>';

			        echo '</tr>';

			    endforeach;

			else :

			    // no rows found

			endif;

    endwhile;

    echo '</table>';

endif;

// Reset postdata
wp_reset_postdata();

?>
