Answer 2

Basic query and output of posts with links:

// задаем нужные нам критерии выборки данных из БД
$args = array(
  'posts_per_page' => 5,
  'post_type' => 'post',
);

$query = new WP_Query( $args );

// Цикл
if ( $query->have_posts() ) {
  echo '<ul>';
  while ( $query->have_posts() ) {
    $query->the_post();
    echo '<li><a href="' . get_permalink() . '">' . get_the_title() . '</a></li>';
  }
  echo '</ul>';
} else {
  // Постов не найдено
}
// Возвращаем оригинальные данные поста. Сбрасываем $post.
wp_reset_postdata();
