Reply To: dynamically generate subfield content

I’m able to set the value of the repeater so that the number of subfields matches the number of subfields in my options repeater.
But I still don’t understand how you would go about setting the values of the subfields from there. If I try to access the subfields I only get the structure and not the content. So even if I wanted to create another filter for each subfield I wouldn’t know the field_key to do so.

function repeater_field_load_value($value, $post_id, $field) {
		
    $keywords = get_field('app_store_metadata_keywords', 'option', true);
    $num_of_keywords = sizeof( $keywords );
	
    if ( $value != $num_of_keywords ) {
        $value = $num_of_keywords;
    }
    
    // This doesn't show any value for the subfields ?
    echo '<pre>';
    print_r( $field['sub_fields'] );
    echo'</pre>';
	
    return $value;
}

add_filter($'acf/load_value/name='my_field_name', 'repeater_field_load_value', 10, 3);
