Language suggestion

Sometimes, you may not want your visitors to be automatically redirected to their preferred language. Instead, you only want to let them know that a better language match was found based on their preferences, and let them decide if the redirection is relevant.

Such a thing is possible using the following methods:

{% if craft.languageRedirector.hasLanguageSuggestion() %}
    {% set currentLanguage = craft.app.i18n.getLocaleById(craft.app.language) %}

    {% set guessedLanguage = craft.languageRedirector.getGuessedLanguage() %}
    {% set guessedLanguageInformation = craft.languageRedirector.getInformationForLanguage(guessedLanguage)|first %}

    {% if currentLanguage and guessedLanguageInformation %}
        <p>{{ 'You are currently visiting the website in ' ~ currentLanguage.displayName|capitalize ~ ' while we think that you may prefer ' ~ guessedLanguageInformation.nativeName|capitalize ~ '.' }}</p>
        <a href="{{ guessedLanguageInformation.url }}" hreflang="{{ guessedLanguageInformation.id }}" lang="{{ guessedLanguageInformation.id }}">{{ 'Switch to ' ~ guessedLanguageInformation.nativeName|capitalize ~ '?' }}</a>
    {% endif %}
{% endif %}
