Add active class and territory name to language switcher

Question

I've worked up this code with big help from @carlcs. I want to set up a class if current locale is turned on.

• Firstly, I tried the easiest way by putting {{ current ? 'my-class' }} into li.
• Secondly, I tried to set variable for current locale.

I've end up by struggling to answer my question, Why all locales are turned on?

{# Language switcher #}
{% set locale = craft.i18n.getCurrentLocale() %}

{# Configure site locales #}
{% set locales = ['en', 'en_gb'] %}

{# Check if locale equals the requested page locale #}
{% if locale == craft.locale %}
    {% set current = true %}
{% else %}
    {% set current = false %}
{% endif %}

{# Give locales class or text #}   
{% if locale == 'en' %}
     {% set territoryCode = 'world' %}
     {% set active = 'uk-active' %}    
{% endif %}

{% if locale == 'en_gb' %}
     {% set territoryCode = 'uk' %} 
     {% set active = 'uk-active' %}     
{% endif %}  


{# This is the current locale #}
<span>{{ territoryCode|upper }}</span>

<ul>
{% set locales = ['en_001', 'en_gb'] %}
{% for locale in locales %}
{% set subTags = locale|split('_') %}
{% set territory = subTags|length > 1 ?craft.i18n.getLocaleData(craft.locale).getTerritory(subTags|last) : '' %}  
{% set language = craft.i18n.getLocaleById(locale).name %}
{% set language = language ?: craft.i18n.getLocaleById(subTags|first).name %}
{% set language = language|replace("/- #{territory}$/", '') %}    

<li {% if active %}class="{{ active }}{% endif %}">
    <a href="{{ craft.config.siteUrl[locale] ~ craft.request.getPath() }}">
       {% if territory and language %}
            {{ territory }} ({{ language }})
       {% endif %}
    </a>
</li>
{% endfor %} 
</ul>

Update

<ul>
{% set locales = ['en_001', 'en_gb'] %}  

 {% for locale in locales %}    

 {# Check if locale equals the requested page locale #}
 {% if locale == craft.locale %}
      {% set current = true %}
 {% else %}
      {% set current = false %}        
 {% endif %}

 {% set subTags = locale|split('_') %}
 {% set territory = subTags|length > 1 ? craft.i18n.getLocaleData(craft.locale).getTerritory(subTags|last) : '' %}  
 {% set language = craft.i18n.getLocaleById(locale).name %}
 {% set language = language ?: craft.i18n.getLocaleById(subTags|first).name %}
 {% set language = language|replace("/- #{territory}$/", '') %}    


 <li class="{{ current is defined ? 'uk-active' }}">
     <a href="{{ craft.config.siteUrl[locale] ~ craft.request.getPath() }}">
        {% if territory and language %}
            {{ territory }} ({{ language }})
        {% endif %}
     </a>
 </li>
 {% endfor %} 
</ul>

Answer 1

The comparison is meant to be used within the for loop that loops your array of locales. And you can of course only compare the current locale tag craft.locale to real locale tags and not with fake ones like 'en_001' that Craft doesn't know about.

{% set locales = ['en', 'en_gb'] %}

{% for locale in locales %}
    {% set current = (locale == craft.locale) ? true %}
{% endfor %}

So you need to find a way to map real locales to your fake ones! The real ones for your craft.locale comparison and the fake ones to get your territories. But then there would be no need to compose fake ones to start with and you would simply map the real locales you installed and use in Craft to the territory names or territory codes for your output string. So let's do this.

{% set locales = {
    'en':    '001',
    'en_gb': 'gb',
    'hu':    'sk',
    'de':    'sk',
} %}

{% for locale, territory in locales %}

    {% set current = (locale == craft.locale) ? true %}

    {% set territory = craft.i18n.getLocaleData(craft.locale).getTerritory(territory) %}
    {% set language = craft.i18n.getLocaleById(locale).name %}
    {% set language = language|replace("/- #{territory}$/", '') %}

    {% if territory and language %}
        <li class="{{ current ? 'myCurrentLocale'}}">
            Territory: {{ territory }},
            Language: {{ language }}
        </li>
    {% endif %}

{% endfor %}
