Thank you John,

As a beginner I am still not able to get it working this way. This is the code I have:

In my functions.php file:

    function my_sort_function($a, $b) {
        if ($a->star_rating == $b->star_rating) {
            return 0;
        } elseif ($a->star_rating < $b->star_rating) {
            return -1;
        } else {
            return 1;
        }
    }

On my home page:

<?php 
$args = array(
    'taxonomy'     => 'sock-club',
    'hide_empty'   => '0'
      );
$terms = get_terms('sock-club', $args);
if ($terms) {
    foreach ($terms as $index => $term) {
        $terms[$index]->star_rating = get_field('star_rating', $taxonomy.'_'$term_id);
    
        $term_list .= '<a href="' . get_term_link( $term ) . '" title="' . sprintf( __( 'View all post filed under %s', 'my_localization_domain' ), $term->name ) . '">' . $term->name . '</a>';
      
    }
    usort($terms, 'my_sort_function');
}

?>

Can you see what is wrong with my code?

Thank you for the quick response.

I am not that advanced when it comes to ACF (excuse the pun). Do you know how I could make the value the single image field?

Hi,

Thank you for the detailed feed. I have been struggling to get this working on my site for the past hour.

I am trying to set the first image in a repeater row as the featured image for each existing and new post.

The repeater is called sock_image and the image field is called sock_images. Any clue on what I am doing wrong? This is what I put in my functions file:

// Set the first sock image uploaded as the featured image
function acf_set_featured_image( $value, $post_id, $field  ){
    
    if($value != ''){
      delete_post_thumbnail( $post_id);
      //Add the value which is the image ID to the _thumbnail_id meta data for the current post
      add_post_meta($post_id, '_thumbnail_id', $value);
    }
 
    return $value;
}

// acf/update_value/name={$field_name} - filter for a specific field based on it's name
add_filter('acf/update_value/name=sock_images', 'acf_set_featured_image', 10, 3);
