我正在使用以下代码输出三个不同类别的帖子。来自加拿大和世界的帖子正确显示,但没有来自美国的帖子。我尝试var_dump($context['posts']);
在 WordPress PHP 文件中转储,该文件确实返回了包括美国在内的所有类别的帖子。{{ dump(post) }}
当我在 Twig 模板中使用 Timber's进行转储{{ dump(posts.united-states) }}
时,会显示以下内容int(0)
。我尝试从类别 slug 中删除连字符并更新for loop
,但这并没有解决问题。
关于导致此问题的任何想法?
PHP 代码
$context = Timber::context();
$timber_post = new Timber\Post();
$query = array(
// Canada, United States, and World categories
'cat' => '3,4,6',
'orderby' => 'title',
'order' => 'ASC',
'posts_per_page' => -1,
);
$posts = Timber::get_posts( $query );
$sorted_posts = array();
foreach ( $posts as $post ) {
// Get first category of post
$category = $post->category();
// Fill post back to sorted_posts
$sorted_posts[ $category->slug ][] = $post;
}
// Add sorted posts to context
$context['posts'] = $sorted_posts;
$context['post'] = $timber_post;
Timber::render( array( 'page-' . $timber_post->post_name . '.twig', 'page.twig' ), $context );
树枝模板代码
{% extends "base.twig" %}
{% block content %}
<section>
<h2>Canada</h2>
{% for story in posts.canada %}
<article class="story" id="story-{{ story.ID }}">
</article>
{% endfor %}
</section>
<section>
<h2>United States</h2>
{{ dump(posts.united-states) }}
{% for story in posts.united-states %}
<article class="story" id="story-{{ story.ID }}">
</article>
{% endfor %}
</section>
<section>
<h2>The World</h2>
{% for story in posts.world %}
<article class="story" id="story-{{ story.ID }}">
</article>
{% endfor %}
</section>
{% endblock %}
