How to implement the previous/next navigation in AnQiCMS
AnQiCMS provides two special template tags for this:prevArchiveand the previous document"),nextArchive(The next document). The cleverness of these tags lies in their ability to intelligently identify adjacent articles based on the context of the current article, without the need to manually pass complex parameters, greatly simplifying the development and maintenance workload.
When you are using the article detail pageprevArchiveWhen the tag is used, it will automatically try to get information about the previous article of the current article; similarly,nextArchiveThe tag will retrieve the next article. If there is no previous or next article (for example, if the current article is the first or last in the category), these tags will return empty values, allowing us to flexibly handle this situation in the template, for example, by displaying a friendly prompt.
Add navigation code in the template

First, let's take a look at the simplest implementation, which will display the title and link of the previous and next articles:
<div class="article-navigation">
{# 上一篇文档 #}
<div class="prev-article">
{% prevArchive prev %}
{% if prev %}
<a href="{{prev.Link}}" title="{{prev.Title}}">
上一篇：{{prev.Title}}
</a>
{% else %}
<span>没有上一篇了</span>
{% endif %}
{% endprevArchive %}
</div>
{# 下一篇文档 #}
<div class="next-article">
{% nextArchive next %}
{% if next %}
<a href="{{next.Link}}" title="{{next.Title}}">
下一篇：{{next.Title}}
</a>
{% else %}
<span>没有下一篇了</span>
{% endif %}
{% endnextArchive %}
</div>
</div>

If there is a value (i.e., there is an article from the previous one), then executeifThe code inside the statement block.<a href="{{prev.Link}}" title="{{prev.Title}}">上一篇：{{prev.Title}}</a>This line of code creates a hyperlink.{{prev.Link}}It will output the URL of the previous article, and{{prev.Title}}it will display the title.{% else %}If:prevIf the variable is empty (i.e., there is no previous article), then executeelseCode within the block, which shows “No previous article.”{% endprevArchive %}and{% endif %}: are used to endprevArchiveTags andifConditional judgment.nextArchiveThe way of using tags andprevArchiveExactly the same, but it processes the data of the next article and assigns it tonextVariable.

Frequently Asked Questions (FAQ)
Q1: Why do some article detail pages show 'No previous article' or 'No next article'?
A1:This usually has several cases. First, if the current article is the first article in the category of your website, then there is no previous article content;On the contrary, if it is the last one, there is no 'next one'.Secondly, these navigation tags of AnQiCMS are sorted according to the publication time or ID of the articles. If adjacent articles are deleted, or the publication order is 'discontinuous', it may also cause the display of 'nothing'.
Q2: Can I customize the display order of the previous/next article, such as sorting by views?
A2: prevArchiveandnextArchiveThe tag itself mainly works based on the direct adjacent relationship of the current article in the time or ID sequence, without built-in parameters to directly change the sorting logic (such as by views). If you need a more complex sorting logic to get the previous or next recommended article, you may need to consider usingarchiveListLabel, combining the current article ID and category ID, get a list sorted according to specific rules, and then manually select adjacent articles.
