Custom post type archive page not showing content

Question

I have registered a custom post type called How to videos .

 register_post_type( 'How to videos', theme_build_post_args( // $slug, $singular, $plural 'how-to-videos', 'How to videos', 'How to videos', array( 'menu_icon' => 'dashicons-video-alt3', 'menu_position' => 20, 'has_archive' => true, 'public' => false, 'supports' => array('title','thumbnail'), ) ) );

The custom post type appears in the admin and I can successfully create posts.

I'm trying to create an archive template where I can display all of the posts in this post type (essentially create a level 1 page, there will be no level 2 pages).

To do this, I have created archive-how-to-videos.php , which looks like this:

 <?php get_header(); ?> this is a test <?php get_footer(); ?>

As you can see, all I'm trying to do when accessing this archive at the moment is display dummy text. But, when accessing /how-to-videos it just shows the header and footer. When inspecting, the text "this is a test" is not on the page.

I have flushed permalinks via admin settings also. No avail.

I have other custom post types which are appearing as they should. Only difference between this post type and others is that, this one is the only one that has 'public' => false .

Ideas on what's happening?

Answer 1

when accessing /how-to-videos it just shows the header and footer

I don't know why is that so, but How to videos is not a valid post type key .

More specifically, the first parameter for register_post_type() is the post type key or slug, and not the post type label which is what you've actually used:

register_post_type(
  'How to videos', // <- this should be how-to-videos
  theme_build_post_args(
    // $slug, $singular, $plural
    'how-to-videos', 'How to videos', 'How to videos',
    ... your code.
  )
);

And because a post type key (should not exceed 20 characters and) may only contain lowercase alphanumeric characters, dashes, and underscores, then it means the above code would result in howtovideos being the post type key and not how-to-videos . (because the whitespaces are automatically removed )

Therefore, the archive template should have been named archive-howtovideos.php and not archive-how-to-videos.php .
