Php RainLab博客-十月CMS-显示特定类别的帖子

我在Posts.php中发现了以下代码-我认为我需要复制它，并将其转换为一个公共函数，将类别限制为sepcific ID。尽管这似乎有些过分了？我可以在前端查询当前函数吗

下面是posts.php代码：

protected function listPosts()
{
    $category = $this->category ? $this->category->id : null;

    /*
     * List all the posts, eager load their categories
     */
    $isPublished = !$this->checkEditor();

    $posts = BlogPost::with('categories')->listFrontEnd([
        'page'       => $this->property('pageNumber'),
        'sort'       => $this->property('sortOrder'),
        'perPage'    => $this->property('postsPerPage'),
        'search'     => trim(input('search')),
        'category'   => $category,
        'published'  => $isPublished,
        'exceptPost' => $this->property('exceptPost'),
    ]);

    /*
     * Add a "url" helper attribute for linking to each post and category
     */
    $posts->each(function($post) {
        $post->setUrl($this->postPage, $this->controller);

        $post->categories->each(function($category) {
            $category->setUrl($this->categoryPage, $this->controller);
        });
    });

       return $posts;
}

前端是这样的：

{% for post in posts %}
    <li>
        <h3><a href="{{ post.url }}">{{ post.title }}</a></h3>
    </li>
{% else %}
    <li class="no-data">{{ noPostsMessage }}</li>
{% endfor %}

{%for posts in posts%}


{%else%}
{{noPostsMessage}
{%endfor%}

有人能给我指出正确的方向吗

干杯，

不确定你想要实现什么。您只想显示特定类别的帖子？ 将blogPosts组件的参数“category filter”设置为特定类别的slug

[blogPosts newsList]
pageNumber = "{{ :page }}"
categoryFilter = "news"
postsPerPage = 100
noPostsMessage = "No posts found"
sortOrder = "published_at desc"
categoryPage = "blog/category"
postPage = "blog/post"
==
{% component 'newsList' %}

这将显示仅来自“新闻”类别的帖子

在再次阅读该插件的文档后偶然发现了这一点。谢谢
