How to display the link and title of the previous and next article in AnQiCMS template?

In website operation, it is crucial to provide visitors with a smooth navigation experience.When a user finishes reading an article, they naturally expect to find more related content, and the 'Previous' and 'Next' links are the key features that meet this need.They can not only improve the user's stay time on your website, but also have a positive impact on search engine optimization (SEO) by building internal link structure.

AnQiCMS provides concise and efficient built-in tags for template developers, allowing you to easily display links and titles of the previous and next articles on the article detail page.Below, we will together learn how to implement this feature in the AnQiCMS template.

Understand core tags:prevArchiveandnextArchive

AnQiCMS provides two special tags for retrieving adjacent article information:

• prevArchive: Used to retrieve information about the 'previous' article of the current article.
• nextArchiveUsed to get the information of the next article of the current article.

These tags work intelligently in the context of the article detail page, automatically determining the current article's ID and category, and finding adjacent articles in the same category.

Basic Usage: Display Links and Titles

The most common requirement is to display the title and corresponding link of the previous and next articles. You can add the following code snippet to the template below the content area or above the comment area on the article detail page:

<nav class="article-navigation">
    <div class="prev-article">
        {# 获取上一篇文章信息，并将其赋值给变量 'prev' #}
        {% prevArchive prev %}
            {# 检查是否存在上一篇文章 #}
            {% if prev %}
                <span>上一篇：</span>
                <a href="{{ prev.Link }}" title="{{ prev.Title }}">{{ prev.Title }}</a>
            {% else %}
                {# 如果没有上一篇文章，则显示提示信息 #}
                <span>上一篇：没有了</span>
            {% endif %}
        {% endprevArchive %}
    </div>
    <div class="next-article">
        {# 获取下一篇文章信息，并将其赋值给变量 'next' #}
        {% nextArchive next %}
            {# 检查是否存在下一篇文章 #}
            {% if next %}
                <span>下一篇：</span>
                <a href="{{ next.Link }}" title="{{ next.Title }}">{{ next.Title }}</a>
            {% else %}
                {# 如果没有下一篇文章，则显示提示信息 #}
                <span>下一篇：没有了</span>
            {% endif %}
        {% endnextArchive %}
    </div>
</nav>

Code analysis:

• {% prevArchive prev %}This tag attempts to retrieve the previous article of the current article, if found, it will store all its information in a namedprev.{% endprevArchive %}This is the end tag.
• {% if prev %}: This is a conditional judgment, used to check.prevWhether the variable successfully retrieves the content (i.e., whether the previous article exists). If it exists, then executeifThe code within the block.
• {{ prev.Link }}: fromprevRetrieve the link address of the previous article in the variable.
• {{ prev.Title }}: fromprevRetrieve the title of the previous article in the variable.
• {% else %}If:prevIf the variable is empty (i.e., there is no previous article), then executeelseThe code inside the block displays the prompt 'Nothing here'.
• nextArchiveThe way of using tags andprevArchiveExactly the same, but it retrieves the information of the next article and stores it in.nextthe variable.

Advanced usage: Add more information

In addition to the title and link, you may also want to display more details of the articles in the navigation, such as thumbnails (Thumb), description (Description) etc., to provide a richer preview.prevandnextThe variable contains various fields in the article, you can call it as needed.

Here is an example of adding a thumbnail to the navigation.

<nav class="article-pagination">
    <div class="pagination-item prev-item">
        {% prevArchive prev %}
            {% if prev %}
                <a href="{{ prev.Link }}" title="{{ prev.Title }}" class="pagination-link">
                    {% if prev.Thumb %}
                        <img src="{{ prev.Thumb }}" alt="{{ prev.Title }}" class="pagination-thumb">
                    {% endif %}
                    <span class="pagination-text">上一篇：{{ prev.Title }}</span>
                </a>
            {% else %}
                <span class="pagination-text no-more">上一篇：没有了</span>
            {% endif %}
        {% endprevArchive %}
    </div>
    <div class="pagination-item next-item">
        {% nextArchive next %}
            {% if next %}
                <a href="{{ next.Link }}" title="{{ next.Title }}" class="pagination-link">
                    <span class="pagination-text">下一篇：{{ next.Title }}</span>
                    {% if next.Thumb %}
                        <img src="{{ next.Thumb }}" alt="{{ next.Title }}" class="pagination-thumb">
                    {% endif %}
                </a>
            {% else %}
                <span class="pagination-text no-more">下一篇：没有了</span>
            {% endif %}
        {% endnextArchive %}
    </div>
</nav>

In this example, we added{% if prev.Thumb %}Determine whether the previous article has a thumbnail and display it. This provides users with a more intuitive navigation cue.

How to apply the code to your template

Important reminder and **practice
