How to correctly refer to the image address of the homepage banner (`item.Logo`) in the template?

As an experienced website operations expert, I fully understand the importance of the website homepage banner.It is not only the "front page" of the website, carrying the brand image and core promotional information, but also the first visual point for users after entering the website.item.LogoIt is a common and basic requirement in daily operation.Today, let's delve into the correct method of referencing the home page Banner image address in AnQiCMS template, so that your website's homepage shines with brilliance.

Understand the AnQiCMS Banner mechanism

AnQiCMS with its concise and efficient template engine, processes the background configuration of Banner data in an intuitive and convenient manner.When we talk about the reference to the homepage banner, the core is to obtain data using specific template tags.bannerList.

bannerList标签是AnQiCMS系统内置的工具，它负责从您的AnQiCMS后台系统中抓取所有与首页Banner相关的数据集合。This data includes key information such as each Banner's image address, link, and ALT text.bannersso that it can be used in templates in a loop.

Exact referenceitem.Logo: Core image address

Once we have passed through{% bannerList banners %}Label successfully retrieved the Banner dataset, the next step is to display them one by one in the HTML structure. Since the home page Banner usually has more than one image, we naturally useforUsing loop structures to iterate and processbannersEach Banner item in the collection. During the loop process, each independent Banner data will be temporarily assigned to a variable nameditem.

At this time, the specific address of each Banner image is clearly displayeditem.Logoin this field.item.LogoThe image path on the server is provided directly, you can place it without any hesitation.<img>Tagssrcin the attribute. For example:<img src="{{item.Logo}}" alt="{{item.Alt}}" />.

Exceptitem.Logo,itemThe variable also includes other fields that are crucial for Banner display, such as:

  • item.LinkThe target URL address linked to this Banner.
  • item.Alt：Image alternative text, crucial for search engine optimization (SEO) and accessibility.
  • item.Title：Banner title or brief description, commonly used for<h5>tags or as links.titleproperties.

实战演示：构建一个基本的Banner区域

Let's look at a real template code snippet that shows how to reference the home page banner image in the AnQiCMS template:

<div class="main-banner">
    {% bannerList banners %}
        {% for item in banners %}
        <a href="{{item.Link}}" target="_blank">
            <img src="{{item.Logo}}" alt="{{item.Alt}}" />
            <h5>{{item.Title}}</h5>
        </a>
        {% endfor %}
    {% endbannerList %}
</div>

In this code block:

  1. {% bannerList banners %}: First callbannerListLabel, assign all Banner data tobanners.
  2. {% for item in banners %}: Then, we traversebannersthis collection, each loop will assign a Banner's data toitem.
  3. <a href="{{item.Link}}" target="_blank">：we have created a link for each Banner, the target address of which comes fromitem.Link.target="_blank"make sure it opens in a new window after clicking, to enhance user experience.
  4. <img src="{{item.Logo}}" alt="{{item.Alt}}" />：The core comes, item.LogoProvided the image source address,item.Altthen the description information for the image was added.
  5. <h5>{{item.Title}}</h5>: If there is a title requirement for the Banner, it can be directly referenced.item.Title.

Advanced Usage: Specific Group Banner and Conditional Judgment

The strength of AnQiCMS lies in its flexibility.In addition to the general home page Banner, you may also need to set specific Banner groups for different events or pages.bannerListTagstypeThe parameter comes into play. Suppose you have created a Banner group named "Event Special" in the AnQiCMS backend, you can accurately call the Banner images under this group in the following way:

<div class="activity-banner">
    {% bannerList banners with type="活动专题" %}
        {% for item in banners %}
        <a href="{{item.Link}}" target="_blank">
            <img src="{{item.Logo}}" alt="{{item.Alt}}" />
        </a>
        {% endfor %}
    {% endbannerList %}
</div>

In addition, in actual website development, you may need to add special styles to the first Banner (such as marking it as "active" in the carousel). AnQiCMS's template engine providesforloop.CounterThis variable can conveniently determine the number of times the current loop runs:

<div class="carousel">
    {% bannerList banners %}
        {% for item in banners %}
        <div class="carousel-item {% if forloop.Counter == 1 %}active{% endif %}">
            <a href="{{item.Link}}" target="_blank">
                <img src="{{item.Logo}}" alt="{{item.Alt}}" />
                <h3>{{item.Title}}</h3>
            </a>
        </div>
        {% endfor %}
    {% endbannerList %}
</div>

Pass{% if forloop.Counter == 1 %}active{% endif %}We can accurately add the first Banner:activeclass name, which is particularly useful when building carousel components.
