我会开始一个新的循环，使用循环函数（the_content（），the_title（）等）获得发布数据。

I would start a new loop, as it's much easier to get post data using the functions made for the Loop ( the_content(), the_title(), etc.)

试试这个作为一个起点：

Try this as a staring point:

<?php
    $new_loop = new WP_Query( array(
    'post_type' => 'post',
        'orderby' => 'category'
    ) );
?>

<?php if ( $new_loop->have_posts() ) : while ( $new_loop->have_posts() ) : $new_loop->the_post(); ?>

<section>
<a href='javascript:history.back();'>&#8592;Tilbake</a>
<header style='font-size: 30px;'>
<h2><?php the_title();?></h2>
</header>
<p><?php the_content();?></p>
</section>

<?php endwhile; else: ?>
<?php endif; ?>
<?php wp_reset_query(); ?>
