Woocommerce how to get meta value from the order object

I'm trying to get a custom meta data field from wc_order. I have to clarify that I'm not a pro in php and I have tried many ways to get field, with:

get_meta()
get_meta_data()
get_post_meta( $order_id )
and so on...

But none of them have worked. I have this order object:

I'm trying to get the following user_instagram value: order > meta_data[3] > current_data > value

Does someone know a way to get it?

Edit

I'm trying to add lty_user_instagram field. This is the function in charge of doing it.

public static function create_ticket_on_placing_order( $order_id, $product_id = false ) {

  if ( get_post_meta( $order_id , 'lty_lottery_ticket_created_once' , true ) ) {
    return ;
  }

  $order = wc_get_order( $order_id ) ;

  if ( ! is_object( $order ) ) {
    return ;
  }

  $user_id = $order->get_user_id() ;
  if ( ! $user_id ) {
    return ;
  }

  $user = get_user_by( 'ID' , $user_id ) ;

  if ( ! $user->exists() ) {
    return ;
  }

  $currency   = $order->get_currency() ;
  $ip_address = ! empty( $order->get_customer_ip_address() ) ? $order->get_customer_ip_address() : lty_get_ip_address() ;

  $ticket_ids = array() ;

  foreach ( $order->get_items() as $item ) {
    $product = $item->get_product() ;
    if ( ! is_object( $product ) || 'lottery' != $product->get_type() || ! $product->has_lottery_status( 'lty_lottery_started' ) ) {
      continue ;
    }

    // Validate product id.
    if ( $product_id && $product->get_id() != $product_id ) {
      continue ;
    }

    $answer          = '' ;
    $answers         = array() ;
    $is_valid_answer = 'no' ;

    if ( isset( $item[ 'lty_lottery_answers' ][ 0 ] ) ) {
      $question_answers = $product->get_answers() ;
      if ( array_key_exists( $item[ 'lty_lottery_answers' ][ 0 ] , $question_answers ) ) {
        $answer  = $question_answers[ $item[ 'lty_lottery_answers' ][ 0 ] ][ 'label' ] ;
        $answers = array(
          'label' => $question_answers[ $item[ 'lty_lottery_answers' ][ 0 ] ][ 'label' ] ,
          'key'   => $item[ 'lty_lottery' ][ 'answers' ] ,
          'valid' => $question_answers[ $item[ 'lty_lottery_answers' ][ 0 ] ][ 'valid' ]
            ) ;

        $is_valid_answer = $question_answers[ $item[ 'lty_lottery_answers' ][ 0 ] ][ 'valid' ] ;
      }
    }

    $args = array(
      'lty_user_id'      => $user->ID ,
      'lty_user_instagram' => "Here is where I want to ser order's user_instagram" ,
      'lty_product_id'   => $product->get_id() ,
      'lty_amount'       => $product->get_price() ,
      'lty_user_name'    => $user->user_login ,
      'lty_user_email'   => $user->user_email ,
      'lty_currency'     => $currency ,
      'lty_order_id'     => $order_id ,
      'lty_answer'       => $answer ,
      'lty_answers'      => $answers ,
      'lty_valid_answer' => $is_valid_answer ,
      'lty_ip_address'   => $ip_address ,
        ) ;
            
    $ticket_numbers = $product->get_ticket_numbers($item);
    if ( ! lty_check_is_array( $ticket_numbers ) ) {
      continue ;
    }

    foreach ( $ticket_numbers as $ticket_number ) {

      $args[ 'lty_ticket_number' ] = $ticket_number ;
      $ticket_ids[]                = lty_create_new_lottery_ticket( $args , array( 'post_parent' => $product->get_lottery_id() , 'post_status' => 'lty_ticket_pending' ) ) ;
    }
            
    if ( ! $product->is_manual_ticket() ) {
      // Update order item meta for automatic type.
      $item->add_meta_data( '_lty_lottery_tickets' , $ticket_numbers ) ;
      $item->add_meta_data( esc_html__( 'Ticket Number( s )' , 'lottery-for-woocommerce' ) , implode( ' , ' , $ticket_numbers ) ) ;
      $item->save() ;
    }

    //Unset metas on placing order.
    self::unset_metas_on_placing_order( $product , $order , $ticket_numbers ) ;
  }

  if ( lty_check_is_array( $ticket_ids ) ) {
    // Update custom order meta for ticket ids.
    update_post_meta( $order_id , 'lty_ticket_ids_in_order' , $ticket_ids ) ;
    update_post_meta( $order_id , 'lty_lottery_ticket_created_once' , '1' ) ;
  }
}

The plugin I'm trying to edit is Lottery for Woocommerce by FantasticPlugins (class-lty-order-handler.php)

Solution

The following solutions have been fully tested on wordpress 5.8 and woocommerce 5+.

They're recommended, if you use update_post_meta to store your metadata as part of the order object.

Please keep in mind, if you're using third party plugins that store the metadata for you, then you may encounter discrepancies.

You could use the following ways to get your metadata:

$order_id = 12345;

$order = wc_get_order($order_id);

1- using $order->get_meta():

echo "<pre>";
print_r($order->get_meta('user_instagram'));
echo "</pre>";

2- using get_post_meta():

echo "<pre>";
echo get_post_meta($order->get_id(), 'user_instagram', true);
echo "</pre>";

3-using get_post_meta($order_id):

echo "<pre>";
print_r(get_post_meta($order_id)['user_instagram'][0]);
echo "</pre>";

4- using $order->get_meta_data():

echo "<pre>";
foreach ($order->get_meta_data() as $object) {
  $object_array = array_values((array)$object);
  foreach ($object_array as $object_item) {
    if ('user_instagram' == $object_item['key']) {
      print_r($object_item['value']);
      break;
    }
  }
}
echo "</pre>";
