The effective organization and convenient navigation of website content are crucial for enhancing user experience and extending visit duration.When visitors are immersed in your article, if they can seamlessly jump to related or adjacent content, it will undoubtedly greatly enhance the continuity of their browsing.AnQiCMS as a fully functional content management system provides intuitive and powerful template tags, helping us easily implement the display of 'Previous' and 'Next' document links and titles on the article detail page.

Understanding the template mechanism of AnQiCMS

AnQiCMS template system adopts a syntax style similar to Django, which allows front-end developers familiar with the syntax to quickly get started. In template files, we mainly use two methods to display content or control logic: using double curly braces{{变量}}Output the value of the variable, as well as using curly braces and percent signs{% 标签 %}Execute logical judgments, loop traversal, or call specific function modules.For the 'Previous' and 'Next' navigation on the article detail page, AnQiCMS has built-in tags that can intelligently identify the current article and provide data for its adjacent articles.

Core Function:prevArchiveandnextArchivetags

To display the details of the article page (usually corresponding to template files such as)archive/detail.htmlShow "Previous" and "Next" articles in the list, we need to useprevArchiveandnextArchiveThese tags work in a very simple way:

  • prevArchivetags[en] : Used to obtain the data of the 'previous' article in the order of publication time for the current article.
  • nextArchivetags[en] : Used to obtain the data of the 'next' article in the order of publication time for the current article.

These tags do not require additional parameters. The system will automatically find the corresponding adjacent articles based on the current article's ID and category (or other internal logic).They will return a variable containing the detailed information of the article, and an empty value will be returned if there is no previous or next article.We can take advantage of this feature to flexibly control the display of navigation.

These tags provide variables that include the article'sId/Title(Title),Link(Link),Description(description),Thumb(thumbnail) and other rich information, which is enough to meet our navigation needs.

Implementing the link and title of the 'Previous Article' article

Assume we want to display a navigation link to the previous article at the bottom of the article. We can write the code in the template like this:

<div class="article-prev-nav">
  {% prevArchive prev %}
    {% if prev %}
      <a href="{{ prev.Link }}" title="{{ prev.Title }}">
        « 上一篇: {{ prev.Title }}
      </a>
    {% else %}
      <span class="no-prev">« 没有了</span>
    {% endif %}
  {% endprevArchive %}
</div>

The meaning of this code is:

  1. {% prevArchive prev %}This line of code attempts to retrieve the data of the 'previous' article of the current article and assign it to a variable namedprev.
  2. {% if prev %}We use conditional judgment to checkprevwhether the variable is empty. IfprevIf it exists (i.e., there is an article before this one), then executeifCode within the block.
  3. <a href="{{ prev.Link }}" title="{{ prev.Title }}">...</a>: Here, we created a hyperlink.{{ prev.Link }}it will output the URL address of the previous article,{{ prev.Title }}The link text will display the title of the previous article.titleThe settings of the attribute also help improve user experience and SEO.
  4. {% else %}IfprevThe variable is empty (i.e., there is no previous article, such as the current article is the first article in the category), then executeelseCode within the block.
  5. <span class="no-prev">« 没有了</span>[en]: Display a prompt message to inform the user that there are no earlier articles. You can hide or beautify this prompt according to your design requirements.
  6. {% endif %}and{% endprevArchive %}[en]: Close the conditional judgment andprevArchiveLabel.

Implement the link and title of the next article

Similar to the implementation of the previous article, to display the link and title of the next article, we usenextArchiveTags:

<div class="article-next-nav">
  {% nextArchive next %}
    {% if next %}
      <a href="{{ next.Link }}" title="{{ next.Title }}">
        下一篇: {{ next.Title }} »
      </a>
    {% else %}
      <span class="no-next">没有了 »</span>
    {% endif %}
  {% endnextArchive %}
</div>

This code's logic is exactly the same as in the previous article, just thatprevthe variable is replaced withnext, and the text direction is adjusted.

Integrated into the article detail page template

In your article detail page template file (for example/template/您的模板目录/archive/detail.html), you can place these two navigation code snippets in the appropriate position, usually below the article content:

<!-- 文章详情内容区域... -->
<div class="article-content">
  {{ archive.Content|safe }} {# 假设 archive 是当前文章变量，Content 是文章内容 #}
</div>

<div class="article-pagination-nav">
  <div class="article-prev-nav">
    {% prevArchive prev %}
      {% if prev %}
        <a href="{{ prev.Link }}" title="{{ prev.Title }}">
          « 上一篇: {{ prev.Title }}
        </a>
      {% else %}
        <span class="no-prev">« 没有了</span>
      {% endif %}
    {% endprevArchive %}
  </div>

  <div class="article-next-nav">
    {% nextArchive next %}
      {% if next %}
        <a href="{{ next.Link }}" title="{{ next.Title }}">
          下一篇: {{ next.Title }} »
        </a>
      {% else %}
        <span class="no-next">没有了 »</span>
      {% endif %}
    {% endnextArchive %}
  </div>
</div>
<!-- 其他模板底部内容... -->

By using the simple tag calls and conditional judgments mentioned above, we can provide users with a clear and convenient 'Previous Article' and 'Next Article' navigation function on the article detail page of AnQiCMS.This not only optimizes the internal link structure of the website, but also helps improve the user's browsing depth and the overall SEO performance of the website.
