How to change tag's language present on page based on language of page?

[sangrampatil111]

We are trying to change tag language depending on page language. We have jcr.title.language_locale property in each tag. but When select page with language other English, it is still showing in english.

Hi @sangrampatil111 ,

Would it be possible for you to share the logs for this.

Maybe the jcr.title.language_locale property is not being correctly set or read when the page language is changed.

Another possibility is that there is a problem with the way that the tags are being displayed on the page, and that they are not properly picking up the language from the jcr.title.language_locale property.

Only way to confirm would be to look at the logs.

Hi @sangrampatil111,

Localized tags requires proper implementation, setting different language versions on tag level is only first step.

On code level you should utilize one of below methods from Tag java api:

• getLocalizedTitle
• getTitle

Both methods rely on Local object that allows to recognize which language version of tag should be returned.

Local can be retrieved using Page java api via:

• getLanguage
• getLanguage(boolean ignoreContent)

Above methods will base on jcr:language property that can be set on page properties level under Advanced tab or on url structure.

Here is sample of Sling model implementation that returns localized list of tags base on url.

@Model(adaptables = {SlingHttpServletRequest.class})
public class TagComponent {

    @Self
    private SlingHttpServletRequest request;

    @SlingObject
    private ResourceResolver resourceResolver;

    private List<String> localizedTags;

    @PostConstruct
    protected void init() {
        localizedTags = new ArrayList<String>();
        PageManager pageManager = resourceResolver.adaptTo(PageManager.class);

        if (pageManager != null) {
            Page page = pageManager.getContainingPage(request.getResource());
            if (page != null) {
                Locale locale = page.getLanguage(true);
                for (Tag tag : page.getTags()) {
                    localizedTags.add(tag.getTitle(locale));
                }
            }
        }
    }

    public List<String> getLocalizedTags() {
        return localizedTags;
    }
}
