In AnQiCMS, the category page is not just a simple list of content, but also an important part of the website's information architecture, as well as a key entry point for displaying specific themes to users and guiding them to delve deeper into browsing.A well-designed category page that not only enhances user experience but also effectively optimizes search engine rankings.This article will provide a detailed introduction on how to flexibly display the detailed information of a specific category in AnQiCMS, including its introduction and beautiful Banner image.

Back-end settings for category information

To display exclusive introductions and Banner images on the category page, you first need to make the corresponding settings in the AnQiCMS backend.Please log in to the backend management interface and then navigate to the 'Content Management' module under the 'Document Category' option.Here, you can edit or create a new category.

In the category editing page, you will find several key input boxes:

• Category Name: This is the category title, which will be displayed directly on the website front end.
• Category introduction: Here you can fill in a brief text to summarize the main content of this category.This introduction is usually used for displaying summaries on category list pages or as an opening introduction on category detail pages.It is also very important for search engine optimization (SEO), and can help search engines understand the core content of category pages.
• Banner imageThis is an image upload area, you can upload one or more images for the current category.These images are usually used at the top of the category page, as a visual focus, enhancing the aesthetics and professionalism of the page.You can upload multiple images to achieve a carousel effect, or you can upload just one as a fixed Banner.

Make sure you have correctly filled in the 'Category Description' and uploaded the 'Banner Image' for the categories that need to be displayed in the background.This background data is the basis for the display on the front end.

The method called in the front-end template

After completing the background settings, next, we need to use the template tags provided by AnQiCMS in the website template to retrieve and display this information.AnQiCMS uses a syntax similar to the Django template engine, making data calls intuitive and easy to understand.

We mainly use in the category page templatecategoryDetailTags to get the detailed information of the category.

Display the category introduction

To display the category overview, you can use it in the template file.categoryDetailtags, and specifyname="Description"To get the category overview field value.

• Get the current category overview:When you are on the details page of a category, AnQiCMS will automatically identify the current category, and you do not need to specify the category ID to directly obtain its introduction:

  
  <div class="category-description">
      {% categoryDetail with name="Description" %}
  </div>
  

• Get the introduction of a specified category:If you need to display the introduction of a specific category on other pages (such as the homepage or navigation menu), you canidspecify the category ID with parameters:

  
  <div class="some-other-place-description">
      {% categoryDetail with name="Description" id="1" %} {# 这里的 "1" 替换为您的分类ID #}
  </div>
  

Display the category Banner image

Category banner images usually exist in the form of image groups, AnQiCMS usesImagesfields to store them. In the template, you need to retrieve this image group and iterate over it to display.

• Display all Banner images (for carousel):If your category has uploaded multiple Banner images and you want them to be displayed in a carousel, you can write the template code like this:

  {% categoryDetail categoryBanners with name="Images" %}
  {% if categoryBanners %} {# 检查是否存在Banner图 #}
    <div class="category-banner-carousel">
      {% for imageUrl in categoryBanners %}
        <img src="{{ imageUrl }}" alt="分类Banner图 - {% categoryDetail with name='Title' %}" />
      {% endfor %}
    </div>
  {% endif %}
  

  This code will traversecategoryBannersAn array of image URLs, and generate a<img>Label. The CSS or JavaScript on the front end (if a carousel effect is needed) will implement the visual effects on this basis.altThe property settings help with SEO and improve the accessibility of images.

• Only display the first Banner image:If the category has multiple Banner images, but you only want to display the first one, you can handle it like this:

  {% categoryDetail categoryBanners with name="Images" %}
  {% if categoryBanners %} {# 再次检查是否存在Banner图 #}
    {% set firstBannerUrl = categoryBanners[0] %} {# 获取数组的第一个元素 #}
    <img src="{{ firstBannerUrl }}" alt="分类Banner图 - {% categoryDetail with name='Title' %}" />
  {% endif %}
  

  Here we usesetThe tag defines a temporary variablefirstBannerUrlto store the URL of the first image.

• Consider using Logo or Thumb as Banner (if only one):If your category usually only has one representative image as a Banner, and this image is also set in the background fields such as "Category Thumbnail Large Image (Logo)" or "Category Thumbnail (Thumb)", then directly calling these fields will be more concise:

  {# 如果Logo字段代表分类Banner图 #}
  {% categoryDetail categoryLogo with name="Logo" %}
  {% if categoryLogo %}
    <img src="{{ categoryLogo }}" alt="分类Banner图 - {% categoryDetail with name='Title' %}" />
  {% endif %}
  

Template file placement and modification

These template codes are usually placed in the category list template file of your AnQiCMS theme directory. According to the AnQiCMS template conventions, the template files for category pages are generally:

• General category list page: {分类模型}/list.htmlfor examplearticle/list.htmlorproduct/list.html)
• Specific category list page: {分类模型}/list-{分类ID}.htmlfor examplearticle/list-10.htmlused for the article category with ID 10)

You can/templateFind the currently used theme folder in the directory, and then modify the correspondinglist.htmlFile.If a specific category needs an exclusive layout, you can also specify a custom template file for it in the backend editing page of that category, through the 'Other Parameters' option under 'Category Template'.

Practical suggestions and precautions
