Topic: Pagination across mutliple custom post types

Hi there,
I have a portfolio archive page that is made up of two different custom post types. I’ve added the URL into the private info.

The page contains a query loop which queries two different custom post types (WordPress Projects & Shopify Projects) and displays the results in chronological order. This is exactly as I want this page to function.

When I click into one of the portfolio items, down the bottom I have added a pagination element of whereby I can move back and forwards between projects. However, the pagination only applies to the custom post type I’m currently on. So, if I am looking at a Shopify project item, I can only move forwards and backwards between other Shopify projects.

This makes sense I guess as the dynamic data is only pulling data from a single custom post type and not both. My question is, can I include both custom post types within the query? Or is there some other way I can create pagination to move between both custom post types in a chronological order.

See attached screenshot of the current dynamic data query.

Hi there,

This is expected behaviour. In WordPress, previous_post_link() and next_post_link() (and their underlying function get_adjacent_post()) only work within the same custom post type (CPT) by default — they don’t cross post types.

Give this PHP code a try to include multiple post types in post navigation:

function include_multiple_cpts_in_navigation( $where, $in_same_term, $excluded_terms, $taxonomy, $post ) {
    // List of post types you want to include
    $post_types = [ 'cpt1', 'cpt2', 'cpt3' ];

    // Convert array into quoted, comma-separated list
    $post_types_in = "'" . implode( "', '", esc_sql( $post_types ) ) . "'";

    // Replace the default post_type condition
    $where = preg_replace( "/post_type = '(.*?)'/", "post_type IN ($post_types_in)", $where );

    return $where;
}
add_filter( 'get_previous_post_where', 'include_multiple_cpts_in_navigation', 10, 5 );
add_filter( 'get_next_post_where', 'include_multiple_cpts_in_navigation', 10, 5 );

Perfect, that works! Thanks very much.

Just reopening this with a follow up question.

I’d like to move this to the top of the page under the header and make it sticky. I’ve moved it to the top ok (thought I haven’t figured why the big gap yet), but is it possible to make it sticky?

Thanks! See attached image.

Hi there,

Try adding this CSS:

.single .paging-navigation {
    position: sticky;
    top: 100px;
}
