我是 Wordpress 的新手，一直在努力创建类别循环。该循环应该：

- echo out the category name (with link to
- echo out the last 5 posts in that category (with permalink to post)

Oops, missed that you wanted 5 posts
糟糕，错过了你想要的 5 个帖子
<?php
//for each category, show 5 posts
$cat_args=array(
'orderby' => 'name',
'order' => 'ASC'
);
$categories=get_categories($cat_args);
foreach($categories as $category) {
$args=array(
'showposts' => 5,
'category__in' => array($category->term_id),
'caller_get_posts'=>1
);
$posts=get_posts($args);
if ($posts) {
echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </p> ';
foreach($posts as $post) {
setup_postdata($post); ?>
<p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
<?php
} // foreach($posts
} // if ($posts
} // foreach($categories
?>

I have made this bit of code to loop through the nested categories. Sharing.
我已经制作了这段代码来循环遍历嵌套类别。分享。
//Start on the category of your choice
ShowCategories(0);
function ShowCategories($parent_category) {
$categories = get_categories(array('parent' => $parent_category, 'hide_empty' => 0));
foreach ($categories as $category) {
?><ul><li><?=$category->cat_name;?><?
ShowCategories($category->cat_ID);
?></li></ul><?
}
}

Take a look at this other Stackoverflow thread:
看看另一个 Stackoverflow 线程：
I posted an answer that I use in production and works like a charm.
我发布了一个我在生产中使用的答案，并且效果很好。
Just remember to adjust the arguments to display only 5 posts, instead of all.
请记住调整参数以仅显示 5 个帖子，而不是全部。
$args = array( 'showposts' => 5 );
Add 'showposts' => 5 to your current array of arguments in the loop that iterates through the posts of each category.
将 'showposts' => 5 添加到循环中的当前参数数组，循环遍历每个类别的帖子。
