Let WordPress display all categories of articles on one page
1. Copy a page.php file and change it to page -abc.php, and create a new page in the WordPress background, and change the fixed link address to abc (this abc can be optional, but it must correspond to page-abc).
2. Find the following code in this page-abc.php file
<?php the_content(); ?>
and add the following code after the code
<?php $cats = get_categories(); foreach ( $cats as $cat ) { query_posts( 'showposts=10&cat=' . $cat->cat_ID ); ?> <h3><?php echo $cat->cat_name; ?></h3> <ul class="sitemap-list"> <?php while ( have_posts() ) { the_post(); ?> <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php } wp_reset_query(); ?> </ul> <?php } ?>
Remember to save and update page-abc.php document.
At this point, let’s refresh the abc page we just created to see if articles under all categories have been displayed? The above code displays 10 articles in each category by default. If you need to display all articles, you only need to change the 10 in the code to a value of 1000 or greater.
