Question

我有一个wordpress网站，我想在类别中显示帖子标题列表。像

Category 1
post 1
post 2

category 2 
post 1
post 2
post 3

category 3
post 1 
post 2


    $show_count = 0; 
    $pad_counts = 0; 
    $hierarchical = 1; 
    $taxonomy = 'filter';
    $title = true;
    $description = true;

    $args = array(
    'show_count' => $show_count,
    'pad_counts' => $pad_counts,
    'hierarchical' => $hierarchical,
    'taxonomy' => $taxonomy,
    'use_desc_for_title' => $description,
    'title_li' => $title
     );

   $categories=get_categories($args);
   foreach($categories as $category) { 
  echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';


    //display posts
$cat_new = $category->term_id;
$post_args = array( 'numberposts' => -1, 'category' => $cat_new, 'caller_get_posts' => 0 );


$myposts = get_posts( $post_args );
    foreach( $myposts as $post ) :  setup_postdata($post); ?>

echo '<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?>';

   endforeach; }

上面的代码只显示了一个类别列表，而不是它下面的帖子标题。

我很困惑，我已经阅读了很多博客，并为此发帖但仍未完成。任何帮助将不胜感激。提前谢谢。

Answer 1

首先，您的代码已损坏，可能会破坏您的主题，因此帖子不会显示。在endforeach之前的最后一行缺少

和的结束标记。 PHP代码中也存在php开始和结束标记，这是非常错误的。

    $show_count = 0; 
        $pad_counts = 0; 
        $hierarchical = 1; 
        $taxonomy = 'filter';
        $title = true;
        $description = true;

        $args = array(
        'show_count' => $show_count,
        'pad_counts' => $pad_counts,
        'hierarchical' => $hierarchical,
        'taxonomy' => $taxonomy,
        'use_desc_for_title' => $description,
        'title_li' => $title
         );

       $categories=get_categories($args);
       foreach($categories as $category) { 
      echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';



    $cat_new = $category->term_id;
    $post_args = array( 'numberposts' => -1, 'category' => $cat_new, 'caller_get_posts' => 0 );


    $myposts = get_posts( $post_args );
        foreach( $myposts as $post ) :  setup_postdata($post);

    echo '<li><a href="'.the_permalink().'">'.the_title().'</a></li>';

       endforeach;
endforeach;
 }

Answer 2

您在此代码中使用了一个非常陈旧且已弃用的参数caller_get_posts：

$post_args = array( 'numberposts' => -1, 'category' => $cat_new, 'caller_get_posts' => 0 );

您应该使用ignore_sticky_posts

替换

$post_args = array( 'numberposts' => -1, 'category' => $cat_new, 'ignore_sticky_posts' => 0 );

Answer 3

<?php
    $query = new WP_Query( array( 'post_type' => 'post','posts_per_page' => -1 ) ); 
    while($query->have_posts()) : $query->the_post();
?>
<ul>
    <li>
    <h3><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h3>
        <a href="<?php the_permalink() ?>" rel="bookmark"><?php the_category(); ?></a> 

    </li>
</ul>
<?php endwhile; ?>

在每个类别wordpress下面显示帖子标题
