一个简单的版本看起来像：

function deny_post_date_change_wpse_131049( $data, $postarr ) {
  $user = wp_get_current_user();
  //   var_dump($user); die; // debugging
  if (in_array($user->ID,array(14,19))) {
    unset( $data[\'post_date\'] );
    unset( $data[\'post_date_gmt\'] );
  }
  return $data;
}
add_filter( \'wp_insert_post_data\', \'deny_post_date_change_wpse_131049\', 0, 2 );
