Question

我需要自定義默認設計的相關文章從噴墨包在wordpress到我的自定義設計我無法找到錯誤，在我的代碼錯了。我在functions.php文件中寫了一個鉤子。

這是我的functions.php鉤

function jetpackme_custom_related() { 
$posts = '<div class="single-article-popularGi">'; 
$posts .= '<h1>related</h1><div class="row">'; 

if (class_exists('Jetpack_RelatedPosts') && method_exists('Jetpack_RelatedPosts', 'init_raw')) { 
    $related = Jetpack_RelatedPosts::init_raw() 
     ->get_for_post_id(
      get_the_ID(), 
      array('size' => 2) 
     ); 

    if ($related) { 
     foreach ($related as $result) { 
      // Get the related post IDs 
      $title = get_the_title($result[ 'id' ]); 
      $link = get_permalink($result[ 'id' ]); 
      $image = featuredOrFirstImage($result[ 'id' ], 'blog-post-image'); 
      $category_name = get_the_category($result[ 'id' ]); 


      $posts .= '<div class="col-sm-3 col-3"><span class="thumbnail-image"><a href="'.$link.'">'.$image.'</a></span></div>'; 
      $posts .= '<div class="post-details col-sm-3 col-3 align-self-center"><div class="entry-cat post-category">'.$category_name.'</div>'; 
      $posts .= '<div class="mostPopularTitle"><h2 class="entry-title"><a class="post-title" href="%s" rel="bookmark">'.$title.'</a></h2>'; 

      $posts .= '<div class="readArticle"><a class="readMorePost" href="'.$link.'">MORE GI></a>'; 
     } 
    } 
} 

$posts .= '</div>'; 
$posts .= '</div>'; 

// Return a list of post titles separated by commas 
if($related){ 
    return $posts; 
}else{ 
    return false; 
} 
} 
add_action('admin_init', 'jetpackme_custom_related'); 

我曾經在single.php中稱它是這樣

<?php echo $related = jetpackme_custom_related();?> 

但沒有什麼顯示和獲得錯誤，不顯示一些時間沒有。任何人都可以請讓我解決出來..

我改變了程序的方式，它適用於me.My代碼

$related_posts = array(); 
$query = array(); 
$query['showposts'] = 2;// Number of posts to show 
if (class_exists('Jetpack_RelatedPosts') && method_exists('Jetpack_RelatedPosts', 'init_raw')) : 
    $related = Jetpack_RelatedPosts::init_raw() 
    ->set_query_name('theme-custom') // optional, name can be anything 
    ->get_for_post_id(get_the_ID(), array('size' => $query['showposts']) 
); 
    if ($related) : 
    foreach ($related as $result) : 
     $related_posts[] = $result[ 'id' ]; 
    endforeach; 
    endif; 
endif; 

if ($related_posts) { 
    $query['post__in'] = $related_posts; 
    $query['orderby'] = 'post__in'; 
    $title = __('Related', 'prefix'); 
} else { 
    $query['post__not_in'] = array($post->ID); 
    $title = __('Related', 'prefix'); 
} 

我曾呼籲，如相關的文章..

<div class="single-article-popularGi"> 
    <h1><?php esc_attr_e($title); ?></h1> 
    <div class="row"> 
    <?php $related = new WP_Query($query); ?> 
     <?php while ($related->have_posts()) : $related->the_post(); ?> 
      <div class="col-sm-3 col-3"> 
       <div class="thumbnail-image"> 
       <a href="<?php the_permalink();?>"><span class="thumb-wrap"><?php the_post_thumbnail('medium', array("class" => "img-fluid")); ?></span></a> 
       </div> 
      </div> 
      <div class="post-details col-sm-3 col-3 align-self-center"> 
       <?php if (has_category()) : ?> 
       <div class="entry-cat post-category"> 
        <?php the_category(' '); ?> 
       </div><!-- end .entry-cats --> 
       <?php endif; // has_category() ?> 
       <div class="mostPopularTitle"> 
       <?php the_title(sprintf('<h2 class="entry-title"><a class="post-title" href="%s" rel="bookmark">', esc_url(get_permalink())), '</a></h2>'); ?> 
       </div> 
       <i class="postIntro"><?php echo $intro = wp_trim_words(get_field('intro'), 20,'...'); ?></i> 
       <div class="readArticle"> 
       <a class="readMorePost" href="<?php echo get_permalink(); ?>">MORE GI></a> 
       </div> 
      </div> 
     <?php endwhile; 
    wp_reset_query(); ?> 
    </div>
