how to store a specific property values of multifield items as string array

Avatar

Level 3

I have a multifield which contains a textfield. I want to store a specific value of that textfield has an array of strings.

 

Below is the content structure

nameDetails (multifield)

       ---------item0 

                      -----------Property name--> name and Property Value--> adobe  (textfield1)

       ---------item1 

                       -----------Property name--> name and Property Value--> league (textfield2)

       ---------item2

                       -----------Property name--> name and Property Value--> communities  (textfield3)

 

I want to store the property values as a string array. Like ["adobe", "league", "communities"]. 

Please help me out here, how I can achieve this?

Use this snippet to return the list as array.

private List<Items> multiitems = new ArrayList<Items>();

@PostConstruct
private void init(){

//Resource multifield = getResource().getChild("multifield");

Iterator<Resource> resource = multifield.listChildren();

String item1;
String item2;
String item3;

while(resource.hasNext()){
Resource childNode = resource.next();
item1 = childNode.getValueMap().get("item1", String.class);
item2 = childNode.getValueMap().get("item2", String.class);
item3 = childNode.getValueMap().get("item3", String.class);

Items item = new Items();
item.setItem1(item1);
item.setItem2(item2);
item.setItem3(item3);

multiitems.add(item);

}

}

Please try the sample code structure, it does store the value as an array. Screenshot attached,Screen Shot 2022-04-06 at 6.22.37 PM.png You can check the sample for vanity url in page properties: - /libs/wcm/foundation/components/basicpage/v1/basicpage/tabs/basic/items/column/items/vanityurl

Hi @anish-s 

I want to get string array in sling model and not store the values as an array in node level

ohh okay, try this sample class. This reads the multifield values and convert it to string:

package com.mysite.core.models;

import java.util.List;

import javax.annotation.PostConstruct;
import javax.inject.Inject;

import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.Model;

@Model(adaptables = Resource.class)
public class Test {
   
   @Inject
   private List<String> testValues;

   @PostConstruct
   protected void init() {
	   String[] array = testValues.toArray(new String[0]);
	   System.out.println(Arrays.toString(array));
   }

   public List<String> getTestValues() {
       return testValues;
   }
}

In sightly you can ereturn this as

<sly data-sly-use.test="com.mysite.core.models.Test">
    <sly data-sly-list.testClass= "${test.testValues}">
	${testClass}
    </sly>
</sly>

String item1;
String item2;
String item3;

while(resource.hasNext()){
Resource childNode = resource.next();
item1 = childNode.getValueMap().get("item1", String.class);
item2 = childNode.getValueMap().get("item2", String.class);
item3 = childNode.getValueMap().get("item3", String.class);

Items item = new Items();
item.setItem1(item1);
item.setItem2(item2);
item.setItem3(item3);

multiitems.add(item);

}

You can use the below sample code to adapt to multifield in any type and get a list, In your case type is String and then convert the list to Array or Json object.
