Shopify新手技术求助：如何按分类展示对应博客文章？

Hey there! Let's get that duplicate article issue sorted for your Shopify multi-blog setup. Since you're using 5 separate blogs as your categories, the core problem right now is that your code is pulling all site-wide articles instead of targeting only the ones tied to each specific blog/category.

Here's how to rewrite your loops correctly: #

1. If you're displaying all 5 blog categories on a single page (like a main blog hub)

Use the global blogs object to iterate through each of your blogs, then nest a loop for only that blog's articles inside:

<!-- Loop through each of your blogs (categories) -->
{% for blog in blogs %}
  <section class="blog-category">
    <!-- Display the blog/category title -->
    <h2>{{ blog.title }}</h2>
    
    <!-- Loop ONLY through articles belonging to this blog -->
    <div class="articles-grid">
      {% for article in blog.articles %}
        <article class="article-card">
          <h3><a href="{{ article.url }}">{{ article.title }}</a></h3>
          <p class="article-excerpt">{{ article.excerpt | strip_html | truncatewords: 25 }}</p>
          <a class="read-more" href="{{ article.url }}">Continue Reading</a>
        </article>
      {% empty %}
        <p>No articles in this category yet.</p>
      {% endfor %}
    </div>
  </section>
{% endfor %}

2. If you're working on a single blog's template (e.g., blog.liquid)

If your individual blog pages are showing all articles instead of just their own, you probably used site.articles instead of the context-specific blog object. Replace your loop with this:

<!-- This pulls ONLY articles from the current blog/category -->
{% for article in blog.articles %}
  <article class="single-article">
    <h1>{{ article.title }}</h1>
    <div class="article-content">
      {{ article.content }}
    </div>
  </article>
{% endfor %}

3. If you need to target specific blogs (not all of them)

If you don't want to display every blog in your store, filter by your 5 category blog handles (you can find each blog's handle in your Shopify Admin under Blogs > [Blog Name] > URL handle):

<!-- List your 5 blog handles here -->
{% assign target_blogs = ['fitness-tips', 'recipe-ideas', 'product-guides', 'customer-stories', 'industry-news'] %}

{% for handle in target_blogs %}
  {% assign current_blog = blogs[handle] %}
  {% if current_blog %}
    <section class="blog-category">
      <h2>{{ current_blog.title }}</h2>
      <div class="articles-grid">
        {% for article in current_blog.articles %}
          <article class="article-card">
            <h3><a href="{{ article.url }}">{{ article.title }}</a></h3>
            <p>{{ article.excerpt | strip_html | truncatewords: 25 }}</p>
            <a href="{{ article.url }}">Read More</a>
          </article>
        {% empty %}
          <p>No articles here yet—check back soon!</p>
        {% endfor %}
      </div>
    </section>
  {% endif %}
{% endfor %}

Quick Checks to Ensure It Works: #

• Double-check that each article is published to the correct blog in your Shopify Admin (when creating/editing an article, select the right blog from the "Blog" dropdown).
• Make sure you're not using site.articles anywhere in your loops—that's the main culprit behind duplicate articles across categories.
