How to modify category.php to list posts alphabetically?

2 comments

1. Try to do all theme modifications in functions.php whenever possible. It keeps the theme files clean and uncluttered. Here’s an example using the pre_get_posts action:

   function order_category_archives( $query ) {
     if ( is_category() && $query->is_main_query() ){ // is_category() can specify a category, if necessary
       $query->set( 'orderby', 'title' );
       $query->set( 'order', 'ASC' );
     }
   }
   
   add_action( 'pre_get_posts', 'order_category_archives' );
   

   Notice that this uses is_category() to modify the query only if we’re looking at a category archive page. An optional parameter can be added to specify which category (or categories) this should be limited to.

   Finally, we use is_main_query() to avoid modifying any additional queries that may be on the page.

2. <ul>
   
   <?php
   
       // we add this, to show all posts in our
       // Glossary sorted alphabetically
       if (is_category())
       {
           $args = array( 'posts_per_page' =&gt; -1, 'orderby'=&gt; 'title', 'order' =&gt; 'ASC' );
   
           $glossaryposts = get_posts( $args );
       }
   
       foreach( $glossaryposts as $post ) :
           setup_postdata($post);
           ?>
           <li>
           <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>;
   
   <?php endforeach; ?>
   
   </ul>
