Sort A ACF Repeater Field Results

Sometimes getting ACF result is not enough. We may need to modify , filter or may be some other action. for that we need to use a ACF hook which is called ” ‘acf/load_value’” . my example is regarding sorting the result according to our choice . but we can use it to modify content.

Filters the field $value after being loaded.

apply_filters( 'acf/load_value', $value, $post_id, $field );

Parameters
$value (mixed) The field value.
$post_id (int|string) The post ID where the value is saved.
$field (array) The field array containing all settings.

Modifers
This filter provides modifiers to target specific fields. The following filter names are available:

   acf/load_value Applies to all fields.
   acf/load_value/type={$type} Applies to all fields of a specific type.
   acf/load_value/name={$name} Applies to all fields of a specific name.
   acf/load_value/key={$key} Applies to all fields of a specific key.

function my_acf_load_value( $value, $post_id, $field ) {
   $order = array();
   foreach( $value as $i => $row ) {
      $order[ $i ] = strtolower($row['field_612f382fb1ad5']);//field key
   }
  array_multisort( $order, SORT_ASC, $value );
  return $value;
}
add_filter('acf/load_value/name=keyword_name', 'my_acf_load_value', 10, 3);

my_acf_load_value( $value, $post_id, $field ) {
    if( is_string($value) ) {
        $value = str_replace( 'Old Company Name', 'New Company Name',  $value );
    }
    return $value;
}

// Apply to all fields.
add_filter('acf/load_value', 'my_acf_load_value', 10, 3);

// Apply to textarea fields.
// add_filter('acf/load_value/type=textarea', 'my_acf_load_value', 10, 3);

// Apply to fields named "hero_text".
// add_filter('acf/load_value/name=hero_text', 'my_acf_load_value', 10, 3);

// Apply to field with key "field_123abcf".
// add_filter('acf/load_value/key=field_123abcf', 'my_acf_load_value', 10, 3);
