AEM - Fetching Multifield Values Using Sling Model

In 6.4 and above multifield values get stored as a node. In order to fetch those values in sling models earlier we used to write methods which include node/resource iterators, but now there is a simple and quick way to do so.

Lets see how to do that : 

Let us suppose we have created a mulfield named "socialLinks " which has "socialMedia" & "socialMediaLink" properties. 

Now in order to read these properties, create a model class for your component which has socialLinks as a multifield . 

@Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)

public class Model {

    /** The social links. */

    @Inject

    private List<SocialLinkModel> socialLinks;

    /**

     * Gets the social links.

     *

     * @return the social links

     */

    public List<SocialLinkModel> getSocialLinks() {

        return new ArrayList<>(socialLinks);

    }

}

Create another class named SocialLinkModel.java and get value of  "socialMedia" & "socialMediaLink" using inject or valueMap.

@Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)

public class SocialLinkModel {

    /** The social media. */

    @ValueMapValue

    private String socialMedia;

    /** The social media link path. */

    @ValueMapValue

    private String socialMediaLink;

    /**

     * Gets the social media.

     *

     * @return the social media

     */

    public String getSocialMedia() {

        return socialMedia;

    }

    /**

     * Gets the social media link path.

     *

     * @return the social media link path

     */

    public String getSocialMediaLink() {

        return socialMediaLink;

    }

}

In your html file write the below code to display values:

<sly data-sly-list.socialLinks= "${model.socialLinks}">

    ${socialLinks.socialMedia}

     ${socialLinks.socialMediaLink}

</sly>

    Hope this helps!!

    Happy Coding 🙏
