I am trying to get a list of my Wordpress categories to display on a Page, but haven't cracked this yet.

So far, I have been able to create a custom category page (category-categoryname.php), to display a list of Page Titles associated with a single category. The code I have used for this includes the following Loop:

while ( have_posts() ) : the_post(); ?>
<h4><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h4>

However, I am now trying to display a list of Category titles on a normal WP Page, using the plugin "Post Snippets" to insert the PHP.

Q1: How do I change The Loop to display all Category titles, instead of Pages associated with a single category?

Q2: Is there anything else I need to add, like some code to functions.php etc?

Q3: Would it be easier to create a custom page template, instead of pasting into a regular page?

Note, I am not trying to filter out any categories from the list, like sub-categories or categories without associated pages/posts etc. Although filtering out 'Uncategorised' would be nice.

Thank you for reading

  • How do you want to display the category titles? Just a simple list? – s_ha_dum Oct 28 '15 at 16:04
  • Note: I wrote my question on the assumption that a different type of Loop would be entered into the Snippet, but please do enlighten me if this is not necessary. Also, in case it is relevant, I am using the 'Genesis framework', with a customised 'Sample' theme. – Toby Oct 28 '15 at 16:05
  • Answer: Yes, just a simple list for the time being. I might develop it into something more fancy in the near future. – Toby Oct 28 '15 at 16:06

I believe you want wp_list_categories (). With a short set of arguments you should be able to get the results you want, including excluding "uncategorized". Something like:

$args = array(
  'exclude' => 1,
);
wp_list_categories( $args ); 
  • Thanks, do you know how to structure the code in the link developer.wordpress.org/reference/functions/wp_list_categories into the correct use on a snippet or custom page? ... I have just tried this: <?php /* Template Name: Show all categories */ ?> <?php wp_list_categories ( string|array $args = '' ) 'show_option_all' (string) 'orderby' (string) default is 'ID' 'order' (string) default is 'ASC' 'show_count' (bool|int) default is 0 ?> <?php genesis(); ?> ... but it has just given me a PHP fail warning on the page - line 5, which starts with: <?php wp_list_categories – Toby Oct 28 '15 at 17:11
  • I'm not in ring of a computer. Give me an hour or so – s_ha_dum Oct 28 '15 at 17:14
  • No probs. Am v. grateful for your help – Toby Oct 28 '15 at 17:21
  • @Toby: See the edit – s_ha_dum Oct 28 '15 at 19:37
  • Many thanks. This works - the snippet displays the categories in a list. I will now try to find the correct Genesis WP commands to display the rest of the page properly. – Toby Oct 29 '15 at 15:38

WordPress Loop only works with posts. Categories (as in terms of category taxonomy) aren't posts and don't have concept of archive in WP.

You can build a list easily via wp_list_categories() and other related functions. For performance reason a page with page template would probably work better for it (so you are not querying number of posts just to throw them away).

  • Thanks, I am using the plugin "Add Categories to Pages" to enable the assigning of Pages under Categories, just like Posts. I would like to be able to add a snippet of PHP in there. I have also tried creating a custom page template. However, it just displays the categories on the top left of the entire page. I would like to be able to place it where I want, but the 3rd PHP command at the bottom seems to generate the entire WP page, so I assume I'll need to get "into" it some how: <?php /* Template Name: All categories */ ?> <?php the_category(', '); ?> <?php genesis(); ?> – Toby Oct 28 '15 at 17:00
  • Between third party plugin and Genesis there I have no guess what is going on in your template there, sorry. :) – Rarst Oct 28 '15 at 17:33
