Introduction
A user in the WPSearch WordPress community recently asked how to create a website directory feature like the one on WPSearch, and whether a plugin is required.
No plugin is needed. This functionality can be implemented purely with code, primarily using WordPress's Custom Post Type feature. If you're unfamiliar with Custom Post Types, please refer to the linked article for a detailed explanation.
Once you understand the concept, you can add a website directory to your own WordPress blog.

Frontend Implementation
To display the directory entries on the frontend of your site, you can use a custom WP_Query. Here is a basic example:
$args = array(
'post_type' => 'site',
'posts_per_page' => 10
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
the_title();
echo '
';
endwhile;
This code queries for 10 posts of the custom 'site' post type and displays their title and content. The visual styling (CSS) for the frontend page must be designed and implemented according to your theme and preferences.
