System language package:This mainly affects the management interface of AnQiCMS, the system-built prompts, and some front-end preset texts.You can select the 'Default Language Pack' in the 'Global Feature Settings' to switch the display language of these built-in parts, such as Chinese or English.
2. Content in multiple languages:For actual content on the website, such as articles, products, and single-page applications, AnQiCMS usually recommends using the "Multi-site Management" feature to implement this.

What makes this label unique is thatNo parameters are required. Simply declare and use it, AnQiCMS will automatically and intelligently find and display all multilingual site information configured in the background management.It returns an array containing multiple site objects, you can accessforLoop through these objects to build a language selector.

Practical exercise: Use it cleverly in the templatelanguagesTag

UnderstoodlanguagesAfter looking at the working principle and available fields of the tag, let's see how to apply it in practice templates to achieve the multilingual switching function and SEO optimization of the website.

Example 1: Build an intuitive language switcher

On a website's navigation bar, footer, or sidebar, a prominent language switcher can greatly enhance user experience.Users can simply tap to access their familiar language version.

{# 假设这是您模板文件中的某个位置，例如 header.html 或 footer.html #}
{%- languages websites %}
{# 只有当存在多个语言站点时才显示切换器，确保页面简洁 #}
{%- if websites and websites|length > 1 %}
<div class="language-switcher">
    <span>切换语言：</span>
    {%- for item in websites %}
    <a href="{{item.Link}}" title="切换到 {{item.LanguageName}}">
        {%- if item.LanguageIcon %} {# 优先显示图标，如果存在 #}
        <img src="{{item.LanguageIcon}}" alt="{{item.LanguageName}} 国旗" class="language-icon" />
        {%- else %} {# 否则显示Emoji表情 #}
        <span class="language-emoji">{{item.LanguageEmoji}}</span>
        {% endif %}
        <span class="language-name">{{item.LanguageName}}</span>
    </a>
    {%- endfor %}
</div>
{%- endif %}
{%- endlanguages %}

In the above code, we first use{%- languages websites %}Label to get information about all language sites. To avoid displaying unnecessary switches when only one language is present, we added{%- if websites and websites|length > 1 %}the judgment. Subsequently, throughforLoop through eachitem(i.e., each language site), utilizingitem.Linkto generate jump links, and combineitem.LanguageIconoritem.LanguageEmojias well asitem.LanguageNameto build intuitive switching options.{%-and-%}The use is to remove the extra blank lines before and after the tag, to keep the output HTML neat.

You need to specify in the<head>area (usually located inbash.htmlorheader.htmlAdd the following code to the public template file:

{# 这是在您的 <head> 标签内 #}

{%- for item in websites %}
<link rel="alternate" href="{{item.Link}}" hreflang="{{item.Language}}">
{%- endfor %}
{%- endlanguages %}

This code will iterate through all configured language sites and generate one for each site:<link rel="alternate" hreflang="xx-xx" href="yyy.com">tags. Among themitem.LinkIt provides the URL for the current language version, whileitem.LanguageIt provides the corresponding language or region code (for exampleenmeans English,en-us
