same here, how to make fields not required?

this is not working anymore. how to disable mandatory fields on checkout?

i tried several things its not working

/**

• PMPro: Entfernt Pflichtfeld-Fehler für State und Phone im Checkout

• Greift nach der internen Validierung
  */
  add_action( 'pmpro_checkout_preheader', function() {
  global $pmpro_msg, $pmpro_msgt;

  if ( empty( $pmpro_msg ) ) {
  return;
  }

  // Messages können String oder Array sein
  if ( is_array( $pmpro_msg ) ) {
  foreach ( $pmpro_msg as $key => $msg ) {
  if (
  stripos( $msg, 'state' ) !== false ||
  stripos( $msg, 'phone' ) !== false
  ) {
  unset( $pmpro_msg[ $key ] );
  }
  }

   // Wenn keine Fehler mehr da sind → Status zurücksetzen
   if ( empty( $pmpro_msg ) ) {
   	$pmpro_msgt = false;
   }
  

  } else {
  // Fallback bei String
  if (
  stripos( $pmpro_msg, 'state' ) !== false ||
  stripos( $pmpro_msg, 'phone' ) !== false
  ) {
  $pmpro_msg = false;
  $pmpro_msgt = false;
  }
  }
  });

@cremigerhonig This is still a valid hook and available in core. There may be another plugin requiring the fields running after this one.

You can try loading this snippet as late as possible to see if this helps:
