This is What to Do If Your WordPress Custom Post Type Archive Returns No Posts
One of the most common issues WordPress developers face is when a custom post type archive page returns no posts, despite having content that should be displayed. This can be a frustrating problem, especially if you've spent time setting up your custom post type and expect it to function correctly.
In this article, we'll dive into the potential causes of this problem and provide step-by-step instructions on how to troubleshoot and resolve the issue. By the end, you'll have a better understanding of what might be causing the problem and the methods you can use to get your custom post type archive working as intended.
Why Your WordPress Custom Post Type Archive Might Not Display Any Posts
There are several potential reasons why your WordPress custom post type archive might not be displaying any posts. Let's explore the most common causes:
1. The Custom Post Type is Not Registered Properly
One of the most common reasons for a custom post type archive not displaying any posts is that the custom post type is not registered correctly. When you create a custom post type in WordPress, you need to register it using the register_post_type()
function.
If there's an issue with the way you've registered the custom post type, such as a typo in the post type name or incorrect arguments, it can prevent the archive page from functioning as expected.
2. The Custom Post Type is Not Publicly Queryable
Another potential issue is that the custom post type is not set to be publicly queryable. When you register a custom post type, you can set the 'public'
argument to true
or false
. If you set it to false
, the custom post type won't be publicly queryable, meaning the archive page won't display any posts.
3. The Custom Post Type is Not Publicly Visible
Similar to the previous point, if the custom post type is not set to be publicly visible, the archive page won't display any posts. You can control the visibility of the custom post type by setting the 'publicly_queryable'
argument to true
or false
when registering the post type.
4. The Custom Post Type Archive Template is Not Set Up Correctly
Another potential cause of the issue is that the custom post type archive template is not set up correctly. WordPress uses specific template files to display the content for custom post type archive pages, and if these templates are not properly configured, the archive page won't display any posts.

5. The Custom Post Type Has No Published Posts
Finally, it's possible that the custom post type simply has no published posts. If you've created the custom post type but haven't actually added any content to it, the archive page will naturally not display any posts.
How to Troubleshoot and Fix the Issue
Now that we've identified the potential reasons for the issue, let's go through the steps you can take to troubleshoot and fix the problem.
1. Check the Custom Post Type Registration
The first step is to double-check the way you've registered the custom post type. Make sure that the register_post_type()
function is being called correctly and that all the arguments are set up properly.
Here's an example of how you might register a custom post type for "Products":
function register_product_post_type() {
$labels = array(
'name' => __( 'Products', 'your-textdomain' ),
'singular_name' => __( 'Product', 'your-textdomain' ),
'menu_name' => __( 'Products', 'your-textdomain' ),
'name_admin_bar' => __( 'Product', 'your-textdomain' ),
'archives' => __( 'Product Archives', 'your-textdomain' ),
'attributes' => __( 'Product Attributes', 'your-textdomain' ),
'parent_item_colon' => __( 'Parent Product:', 'your-textdomain' ),
'all_items' => __( 'All Products', 'your-textdomain' ),
'add_new_item' => __( 'Add New Product', 'your-textdomain' ),
'add_new' => __( 'Add New', 'your-textdomain' ),
'new_item' => __( 'New Product', 'your-textdomain' ),
'edit_item' => __( 'Edit Product', 'your-textdomain' ),
'update_item' => __( 'Update Product', 'your-textdomain' ),
'view_item' => __( 'View Product', 'your-textdomain' ),
'view_items' => __( 'View Products', 'your-textdomain' ),
'search_items' => __( 'Search Products', 'your-textdomain' ),
'not_found' => __( 'Not found', 'your-textdomain' ),
'not_found_in_trash' => __( 'Not found in Trash', 'your-textdomain' ),
'featured_image' => __( 'Featured Image', 'your-textdomain' ),
'set_featured_image' => __( 'Set featured image', 'your-textdomain' ),
'remove_featured_image' => __( 'Remove featured image', 'your-textdomain' ),
'use_featured_image' => __( 'Use as featured image', 'your-textdomain' ),
'insert_into_item' => __( 'Insert into Product', 'your-textdomain' ),
'uploaded_to_this_item' => __( 'Uploaded to this Product', 'your-textdomain' ),
'items_list' => __( 'Products list', 'your-textdomain' ),
'items_list_navigation' => __( 'Products list navigation', 'your-textdomain' ),
'filter_items_list' => __( 'Filter Products list', 'your-textdomain' ),
);
$args = array(
'label' => __( 'Product', 'your-textdomain' ),
'description' => __( 'Custom post type for products', 'your-textdomain' ),
'labels' => $labels,
'supports' => array( 'title', 'editor', 'thumbnail' ),
'taxonomies' => array( 'category', 'post_tag' ),
'hierarchical' => false,
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'menu_position' => 5,
'show_in_admin_bar' => true,
'show_in_nav_menus' => true,
'can_export' => true,
'has_archive' => true,
'exclude_from_search' => false,
'publicly_queryable' => true,
'capability_type' => 'post',
);
register_post_type( 'product', $args );
}
add_action( 'init', 'register_product_post_type' );
Make sure that the 'public'
and 'publicly_queryable'
arguments are both set to true
. Also, check that the post type name (in this case, 'product'
) matches the name you're using to query the archive page.
2. Check the Custom Post Type Archive Template
The next step is to ensure that the custom post type archive template is set up correctly. WordPress looks for specific template files when displaying the archive page for a custom post type.
The template file that WordPress will use is determined by the following hierarchy:
archive-{post_type}.php
archive.php
index.php
If the archive-{post_type}.php
file doesn't exist in your theme, WordPress will fall back to the archive.php
file, and if that doesn't exist, it will use the index.php
file.
Make sure that you have either the archive-{post_type}.php
file or the archive.php
file in your theme, and that the content inside the file is properly structured to display the custom post type's content.
3. Verify the Custom Post Type Has Published Posts
If you've checked the custom post type registration and the archive template, and you're still not seeing any posts, the issue might be that the custom post type simply has no published posts.
You can check this by going to the WordPress admin dashboard, navigating to the custom post type's menu, and verifying that there are indeed posts that have been published.
If the custom post type has no published posts, you'll need to create some content and publish it before the archive page will display anything.
4. Check for Conflicts with Other Plugins or Themes
In some cases, the issue with the custom post type archive not displaying any posts might be caused by a conflict with another plugin or theme on your WordPress site.
Try disabling any plugins that might be interfering with the custom post type functionality, and see if that resolves the issue. You can also try switching to a different theme to see if the problem is theme-related.
5. Use the pre_get_posts
Action to Modify the Query
If you've tried all of the above steps and you're still not seeing any posts on the custom post type archive page, you can use the pre_get_posts
action to modify the query that WordPress uses to retrieve the posts.
Here's an example of how you might use the pre_get_posts
action to ensure that the custom post type is included in the archive query:
function include_custom_post_type_in_archive( $query ) {
if ( $query->is_archive() && !is_admin() && $query->is_main_query() ) {
$query->set( 'post_type', array( 'post', 'product' ) );
}
}
add_action( 'pre_get_posts', 'include_custom_post_type_in_archive' );
This code will ensure that the 'product'
custom post type is included in the archive page query, along with the standard 'post'
post type.
