How to retrive or display added cq:tags on the page using tag manager

[Tessa_learner1]

Hi all, 

I have created one custom tab under properties and given tagfield to let the author to select tags. Now I want to display those selected tags in the page. How can I do that ??

You should resolve a tag via TagManager (https://developer.adobe.com/experience-manager/reference-materials/6-5/javadoc/index.html?com/day/cq...

 resourceResolver.adaptTo(TagManager.class)

@Tessa_learner1 It should be straight forward:

@Model(adaptable=Resource.class)

public class myClass {

@Self

Resource resource;
List<String> tagNames;
@PostConstruct

public void init() {

  	PageManager pm = resource.getResourceResolver().adaptTo(PageManager.class);
  	Page containingPage = pm.getContainingPage (resource);
  	ValueMap pageProperties = containingPage.getProperties();
	String[] tags = pageProperties.get("cq:tags", new String[0]);
        tagNames = new ArrayList<>();
	TagManager tagManager = resourceResolver.adaptTo(TagManager.class);
	for(String tag : tags){
		Tag tag = tagManager.resolve(tag);  
                tagNames.add(tag.getTitle);
	}
}

}

You can display the list using sightly in the component.

Thanks

You should use InheritanceValueMap to get page properties in Sling Model and Use Tag Manager to Resolve cq:tags.

@Model(adaptables = SlingHttpServletRequest.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class TagReadingFromPageProperties {

    @Inject
    private InheritanceValueMap pageProperties;

    @Self
    private SlingHttpServletRequest request;

    Map<String, String> tagMap;

    @PostConstruct
    protected void init() {
        String[] allTags = pageProperties.get("cq:tags", String[].class);
        TagManager tagManager = request.getResourceResolver().adaptTo(TagManager.class);
        tagMap = new HashMap<>();

        for (String tags : allTags) {
            Tag tag = tagManager.resolve(tags);
            tagMap.put(tag.getName(), tag.getTitle());
        }
    }

    public Map<String, String> getTagMap() {
        return tagMap;
    }
}

You can iterate tagMap to get list through sightly.
