Question

我在Posts.php中找到了以下代码 - 我认为我基本上需要复制它并将其转换为将类别限制为特定ID的公共函数。虽然这看起来有点矫枉过正？我可以查询前端的当前功能吗？

这是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;
}

前端的

是：

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

有人能指出我正确的方向吗？

干杯，

不确定要实现的目标。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' %}

这将仅显示来自“新闻”类别的帖子
