Pull Two Posts Into Custom Post Type `single-cpt.php`

文章数量:1325713

I have a custom post type and in the CPT's single-cpt.php file I would like to pull in two posts instead of one.

The two posts will be the post the user clicked in the relevant archive, and the next post in date order (i.e. the default post sorting method of WordPress). The reason for this is the posts are essentially small, useful pieces of information and having two posts pulled in will create a better SEO and user experience.

Normally when I want to pull in a set number of posts on an archive page I would use WP_Query() and set 'posts_per_page' => 2 but out of the box this won't work on a single-cpt.php file because such code pulls in posts that are the most recent, not the post that was clicked on the archive page (and then the next most recent).

What I'm looking for is something that works with the WP loop so each post looks the same, but pulls in two posts (the selected one from the archive and then the next one in date order).

Note: If this isn't possible with WP_Query() any other way to do it would be most welcome.

<?php 
$newsArticles = new WP_Query(array(
    'posts_per_page' => 2,
    'post_type'=> 'news'
));
while(  $newsArticles->have_posts()){
        $newsArticles->the_post(); ?>

// HTML content goes here

<?php } ?>
<?php wp_reset_postdata(); ?>

Any help would be amazing.

Try this:

<?php
$current_id = get_the_ID();
$next_post = get_next_post();
$next_id = $next_post->ID;
$cpt = get_post_type();
$cpt_array = array($current_id, $next_id);
$args = array(
   'post_type' => $cpt,
   'post__in' => $cpt_array,
   'order_by' => 'post_date',
   'order' => 'ASC',
);
$the_query = new WP_Query($args);
if($the_query->have_posts()):
    while($the_query->have_posts() ): $the_query->the_post();
       echo '<h2>'.the_title().'</h2>';
    endwhile;
endif;
wp_reset_postdata();
?>

Tested locally and seems to work fine. get the current post id get the next post id get the current post post type run query

If I'm understanding you correctly, on your single CPT template, I'd do something like this:

$next_post = get_next_post();

Which will chronologically get the next page object, which you can then use built in parameters (found here) to output the content parts you need, such as:

echo $next_post->post_title;

Which will output the next pages title.

I didn't put it into a template part, but that would be a fairly simple next step I think. Here's what I would do though:

<!-- The original loop -->
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
    <?php the_post_thumbnail( 'medium' ) ?>
    <h3><?php the_title(); ?></h3>
    <span class="date"><?php the_date( ); ?></span> <span class="author"><?php the_author_nickname(); ?></span>
    <?php the_content(); ?>
<?php endwhile; endif; ?>

<!-- Get Next Post Data -->
<?php $next_post = get_next_post(); ?>

<!-- Format Next Post to mimic the above -->
<img src="<?php get_the_post_thumbnail_url( $next_post->ID, 'medium' ); ?>">
<h3><?php echo $next_post->post_title; ?></h3>
<span class="date"><?php echo $next_post->post_date; ?></span> <span class="author"><?php echo get_the_author_nickname( $next_post->post_author ); ?></span>
<?php echo get_the_content( $next_post->ID ); ?>

This echos the original loop at the top of the page, when inside the loop. Then, the loop ends, and the next post is called. The markup for that next post call is identical to the original post, thus you would end up with a like-for-like post layout on one post page.
