我在Wordpress的第一天，一切都不顺利。。。我只是有一个简单的循环，我希望在其中显示特定类别的一些帖子。这是我的代码：

<?php 
    $args = array(
        \'numberposts\' => 5,
        \'category\' => 2,
        \'offset\' => 0,
        \'order\' => \'date\',
        \'post_type\' => \'post\',
        \'post_status\' => \'publish\'
    );
    $foodPosts = get_posts($args);
    foreach ($foodPosts as $foodPost) : setup_postdata($foodPost); 
?>
    <div><?php the_permalink(); ?></div>
    <div><?php the_title(); ?></div>
    <div><?php the_content(); ?></div>
<?php endforeach; wp_reset_postdata(); ?>

这是输出：

http://10.0.1.174/mysite/?p=7
Cool post title
this is yet another food post

http://10.0.1.174/mysite/?p=7
Cool post title
this post is in the food category

http://10.0.1.174/mysite/?p=7
Cool post title
this is a post about food

因此，每个帖子的内容都是正确的，但由于某种原因，所有的永久链接和标题都与第一篇帖子相同。怎么了？

<?php 
    $args = array(
        \'posts_per_page\' => 5,
        \'cat\' => 2,
        \'offset\' => 0,
        \'order\' => \'date\',
        \'post_type\' => \'post\',
        \'post_status\' => \'publish\'
    );
    $post_query = new WP_Query($args);

    if($post_query->have_posts()) : while($post_query->have_posts()) : $post_query->the_post();   
?>
    <div><?php the_permalink(); ?></div>
    <div><?php the_title(); ?></div>
    <div><?php the_content(); ?></div>
<?php
endwhile;
endif;
wp_reset_postdata();
?>
