Wordpress 模板自定义 > 相关帖子循环输出当前 post

Wordpress Template customization > Related Posts Loop outputting from current post

所以我试图输出一个循环,其中包含来自同一类别的 3 posts。当它输出每个项目的循环时,它似乎正确地拉动了一切 除了 只有 get_the_content 是正确的。其他数据(图像、标题、link)正在输出当前 post 的值。

所以基本上我需要让这个循环获得 the_post_thumbnail 和 the_title 和 get_permalink 的正确值。

<?php
/**
 * The template used for displaying page content
 *
 * @package WordPress
 * @subpackage Twenty_Fifteen
 * @since Twenty Fifteen 1.0
 */
?>

<?php
$related = get_posts( array( 'category__in' => wp_get_post_categories($post->ID), 'numberposts' => 3, 'post__not_in' => array($post->ID) ) );
if( $related ) {
?>
<div class="related-posts">
    <h2>Related Posts</h2>
<?php    foreach( $related as $related_post ) {
        setup_postdata($related_post);
?>
<article>

    <div class="post-thumbnail">
        <?php the_post_thumbnail('thumbnail'); ?>
    </div><!-- .post-thumbnail -->

    <?php the_title( '<h3>', '</h3>' ); ?>
    <p>
    <?= wp_trim_words( get_the_content(), 10, '<a href="'. get_permalink() .'"> Read More...</a>' ); ?>
    </p>

</article>
<?php        
    }
?>
</div>    
<?php 
} 
wp_reset_postdata();
?>

由于 setup_postdata 函数,您遇到了问题。这个函数接受一个对象作为参数,它应该是 $post

检查文档。 https://codex.wordpress.org/Function_Reference/setup_postdata

<?php
$related = get_posts( array( 'category__in' =>     wp_get_post_categories($post->ID), 'numberposts' => 3, 'post__not_in' => array($post->ID) ) );
if( $related ) {
?>
<div class="related-posts">
    <h2>Related Posts</h2>
<?php
  global $post;
  foreach( $related as $post ) {

        setup_postdata($post);
?>
<article>

    <div class="post-thumbnail">
        <?php the_post_thumbnail('thumbnail'); ?>
    </div><!-- .post-thumbnail -->

    <?php the_title( '<h3>', '</h3>' ); ?>
    <p>
<?= wp_trim_words( get_the_content(), 10, '<a href="'. get_permalink() .'"> Read     More...</a>' ); ?>
    </p>

</article>
<?php
    }
?>
</div>
<?php
}
wp_reset_postdata();
?>
