Creating a Multilingual Site

You can use language variants to set up a multilingual site. Language Variants allow you to have variants of the same content all under the same project. So, if you open a page and a language variant is enabled, you will see the option to switch the language from the drop-down list. Additionally, you can view or input the translated content.

This tutorial explains how to set up a basic multilingual website.

Adding a New language

To add a new language, follow these steps:

1. Go to the Settings section.

2. Go to Languages in the Settings tree. The Languages window opens in the editor.

3. Click Add Language. The Add Language window opens in the editor.

4. Select a Language from the dropdown list. In this tutorial, we will pick Danish.
5. In Settings, select the following options to set the new language as the:

   • Default language for your site, toggle Default Language.

   • Mandatory language for your site, toggle Mandatory Language.

6. Select a Fallback Language from the drop-down list.
7. Click Save.

Adding Multiple Languages

We can add multiple languages depending on our website requirements. In the previous step, we have already set Danish as our default language. We will now set-up English and German as our variants for this tutorial.

1. Go to Languages in the Settings tree and click Add Language.

2. For English Variant:

   • Select English (United States) from the drop-down list.

   • Click Save.

3. For German Variant:

   • Select German from the drop-down list.

   • Toggle Mandatory Language option.

   • Select Danish from the Fallback Language drop-down list.

   • Click Save.

Changing the Default Language of a Website

To change the default language of a website:

1. Go to Languages in the Settings tree.

2. Select the language you want to set as the new default language.

3. Toggle Default Language.
4. Click Save.

Changing the Default Backoffice Language of a User

To change the default language of a User:

1. Go to Users section.

2. Select the user whose backoffice language you wish to change.

3. Select the new language from the Language drop-down list.
4. Click Save.

Document Types

For this tutorial, we will create the following document types:

• Home Page
• Blogs
• Contact Us

Enabling Language Variants on Document Types and Properties

To enable language variants on Document Types, follow these steps:

1. Go to the Settings tab.

2. Select Contact Us from the Document Types folder.

3. Go to the Permissions tab and toggle Allow vary by culture
4. Click Save.

5. Go to the Design tab.

6. Click on the gear icon ⚙ of the Page Title and toggle Allow vary by culture.
7. Click Submit.

8. For this tutorial, we will not make any changes to the Address. Click Save.

Viewing the Language Variants in the Content section

When you return to your content node you will notice two things:

1. At the top of the content tree, there is a dropdown to view the content tree in the language of your choice.
2. To the right of the content name, there is now a dropdown where you can select a language. You can also open a split view so you can see two languages at once.

Adding Culture and Hostnames to the Root Node of the Website

To add culture and hostnames, follow these steps:

1. Go to the Content tab.

2. Right-click on the ... dots next to the Contact Us content node and select Culture and Hostnames...

3. In the Culture and Hostnames... pane, let's add a domain for each hostname, like it's done here:
4. Click Save.

Using Side-by-Side Mode for Editing Content

To use side-by-side mode for editing content at the same time, follow these steps:

1. Go to the Contact Us node. You will find a language dropdown next to the title at the top:
2. Click the dropdown and hover over the new language. You will see an Open in Splitview option will appear.
3. Click Open in Splitview. In this splitview, we can see the content node with each language side by side.

   You may notice that the Address and other fields are greyed out - this is because we haven't checked the Allow vary by culture checkbox.

   To enable these fields, follow the steps mentioned in the Enabling Language Variants on Document Types and Properties section.

Adding Language Variants to the Content

To add language variants to the content.

1. Go to the Contact Us node.

2. Enter the Name for your content node and the Page Title in the new language.

3. Click Save and Publish. The Ready to Publish window opens providing the option to publish in one or more languages.
4. You can select either one or multiple languages and click Publish.

Rendering Variant Content in Templates

To render the values of the Contact Us page, use the following in the template:

@Model.Value("pageTitle")

The .Value() method has a number of optional parameters that support scenarios where we want to "fall-back" to some other content, when the property value does not exist on the current content item. To use the fallback type, add the @using Umbraco.Cms.Core.Models.PublishedContent; directive.

To display a value for a different language, if the language we are requesting does not have content populated:

@Model.Value("pageTitle", "en-Us", fallback: Fallback.ToLanguage)

For more information, see the Using fall-back methods article.

Using Dictionary Items

Depending on how your site is set up, not all content is edited through the content section. Some of the content may be written in the template or labels of the content node and dictionary items can play a part here. Dictionary items store a value for each language. They have a unique key and can be managed from the Translation section. For this tutorial, let's add dictionary items for the Address and Contact Number labels of the Contact Us page.

Creating Dictionary Items

To create dictionary items:

1. Go to the Translation section.

2. Right-click Dictionary in the Translation tree and select Create.

3. Enter a Name for the dictionary item. Let's say Address and click Create.

4. Enter the different language versions for the dictionary item.
5. Click Save.

6. Similarly, we will add different language versions for the Contact Number field.

Rendering Dictionary Items

To render dictionary items in the template, replace the text with the following snippet:

@Umbraco.GetDictionaryValue("Address")
@Umbraco.GetDictionaryValue("Contact Number")

Adding a Translator to the Website

You can assign a Translator when you need a 1-1 translation of your site. For example, let's say we originally created a website in "Danish" which works from a .dk domain and now there is a need for an "English" site on a .com domain. In this case, it might be easier to copy the entire danish site and then provide access to a Translator who can then translate the site page by page.

Translators are used for the translation workflow. By default, Translators have permission to Browse and Update nodes. Someone must review the translations of site pages before publishing the nodes. For more information on managing User Groups, assigning access or User permissions, see the Users article.

Viewing the Language Variant on the Browser

To view the language variant on the browser, follow these steps:

1. Go to the Content tab.

2. Select your new language from the language dropdown above your content tree.

3. Select the Contact Us node and go to the Info tab.

4. You will notice the links with the new language domain added to it. If it's not there, you might need to refresh the page.
5. Click on the link to view the new language varied node in the browser.

6. Alternatively, you can add the domain name to your localhost in the browser. For example: http://localhost:xxxx/da/

For viewing purposes, I've added a stylesheet to my website. The final result should look similar to the image below:

Danish Version:

German Version:

Using Multiple languages across APIs

When requesting content over an API, the culture will fall back to the default, unless explicitly set.

To do this, you can use the IVariationContextAccessor.

public class ExampleController : SurfaceController
{
    private readonly ILocalizationService _localizationService;
    private readonly IVariationContextAccessor _variationContextAccessor;

    public ExampleController(IUmbracoContextAccessor umbracoContextAccessor, IUmbracoDatabaseFactory databaseFactory, ServiceContext services, AppCaches appCaches, IProfilingLogger profilingLogger, IPublishedUrlProvider publishedUrlProvider, ILocalizationService localizationService, IVariationContextAccessor variationContextAccessor) : base(umbracoContextAccessor, databaseFactory, services, appCaches, profilingLogger, publishedUrlProvider)
    {
        _localizationService = localizationService;
        _variationContextAccessor = variationContextAccessor;
    }

    public IActionResult Index(string culture = null)
    {
        IEnumerable<ILanguage> UmbracoLanguages = _localizationService.GetAllLanguages(); //a helpful method to get all configured languages
        var requestedCulture = UmbracoLanguages.FirstOrDefault(l => l.IsoCode == culture);

        if (requestedCulture != null)
        {
            _variationContextAccessor.VariationContext = new VariationContext(requestedCulture.IsoCode);
        }

        //this will now be in the requested culture
        var content = UmbracoContext.Content.GetAtRoot();

        //Content requested in this View Component will now be in the requested culture
        return ViewComponent();
    }
}

Creating a Language Switching Navigation

To navigate between languages, we need to do two key things:

1. Get all the languages that the site can provide

2. Identify the language used on the current page

Once you have these, you need to loop through the languages and provide links to each home node.

Getting all the languages for a site

There are two ways to achieve this. One is to use localizationService.GetAllLanguages(); to call the database, which is expensive and ideally includes caching.

The alternative is to get the Home node and find all cultures associated with it. This has a few benefits including speed and providing us with a link to show the user. It is the process you will use when following this guide.

Identify the language for the current page

This is achieved in cs.html files using umbracoHelper.AssignedContentItem.GetCultureFromDomains();.

Steps

Now that you have what you need, take the following steps to create a working example.

1. Create a new view called Navigation.cshtml

2. Paste in the following code:

@using Umbraco.Cms.Web.Common
@inject IUmbracoHelperAccessor _umbracoHelperAccessor;

@{
    _umbracoHelperAccessor.TryGetUmbracoHelper(out var umbracoHelper);

    var homePage = umbracoHelper.ContentAtRoot().FirstOrDefault(c => c.ContentType.Alias == "{{homeNodeContentAlias}}");
    var cultures = homePage?.Cultures;
}

@if (cultures.Count > 1)
{
    <ul aria-label="Language switcher">
        @foreach (var cult in cultures)
        {
            //get the settings for this culture
            System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo(cult.Key);
            //if the current page has a language variant, otherwise link to the homepage language variant
            string langUrl = umbracoHelper.AssignedContentItem.Url(cult.Key, UrlMode.Relative) ?? homePage.Url(cult.Key, UrlMode.Relative);

            <li>
                @if (cult.Key.ToLower() == umbracoHelper.AssignedContentItem.GetCultureFromDomains().ToLower())
                {
                    <span aria-current="true" >@culture.NativeName</span>
                }
                else
                {
                    <a href="@langUrl" hreflang="@cult.Key" lang="@cult.Key" >@culture.NativeName</a>
                }
            </li>
        }
    </ul>
}

1. Replace {{homeNodeContentAlias}} with the Document Type alias of your Home node.

This will render links to either the language variant of the current page or the home node for the language variant.

Additionally, System.Globalization.CultureInfo is used to obtain the native name of the language being rendered. This is useful if a user does not speak the default language.
