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

<h3><?php the_title() ?></h3>

<?php the_content() ?><br><a href="<?php the_permalink(); ?>">more info</a> 

<?php endwhile; ?>  

Answer 1

So if you want to select multiple categories, set multi=>true to your select option. Then you will be provided with the category IDs and you can query accordingly.

Answer 2

如果可以/想要更改模板的该部分，也可以使用WP_Query的类别参数 ，并将多个类别作为数组传递。

$query = new WP_Query( 'cat=2,6,17,38' );
