Get value from Structure Field for Journal Article/Web Content in Liferay.

During your liferay development, many time you need get value from DDM Structure field. So, here i have piece of code which gives you value of structure field for journal article/ web content.

Suppose you have article content field data(from JournalArticle table) something like (Mention only one field for example.)...


<?xml version="1.0"?>

 <root available-locales="en_US" default-locale="en_US">
  <dynamic-element name="country" type="text" index-type="" index="0" instance-id="Page_Title">
  <dynamic-content language-id="en_US"><![CDATA[India]]></dynamic-content>
  </dynamic-element> 
 </root>


Then your code to get value of country field is like...

JournalArticle article = JournalArticleLocalServiceUtil.getArticle(...);

Document document = SAXReaderUtil.read(article.getContent());

Node node = document.selectSingleNode("/root/dynamic-element[@name='country']/dynamic-content");

String country = node.getText();


if you have multiple field then your code looks like...(Suppose your field have two times as repeated field )

1) Access first element value is....

Node node = document.selectSingleNode("/root/dynamic-element[@name='country' and @index='0']/dynamic-content");
String country = node.getText()


2) Access second element value is....

Node node = document.selectSingleNode("/root/dynamic-element[@name='country' and @index='1']/dynamic-content");
String country = node.getText()



HTH...!!!

Template : some important variable in template(.vm)

Hi All,

   Many time we use webcontent OOTB functionality for our solution. for that we also use Structure/Template. here Template is render part of WebContent. so many time developer stuck with how to get value of some important properties like theme-dispaly,scopegroupid,image path, etc. so, here give some instruction for that.

1) to get instance of class (some times we can't get accesss class by serviceLocator.findService())
$portal.getClass().forName("com.liferay.portlet.dynamicdatamapping.storage.StorageEngineUtil").newInstance()   

2)currentScopegroupid 
    - $getterUtil.getLong($request.get("theme-display").get("scope-group-id"))
    - $request.theme-display.scope-group-id
3) images path in theme
    $request.get("theme-display").path-theme-images
4) themeDispaly
    $request.theme-display
5) globalScopeGroupId
    $groupId

5) find service
 $serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFileEntryLocalService")


Enjoy!!!

Servidce/Util classes access in template (.vm) file in Liferay

Hi Developers,

Many times you need to access services/util class in template. 

Below is some importance hits for the same.

=> Access services using findService method in Velocity(vm)

#set ($userLocalService= $serviceLocator.findService("com.liferay.portal.service.UserLocalService"))

=>Access util class using  findUtil Method for inbuilt Util of Liferay

#set ($journalContentUtil = $utiLocator.findUtil("com.liferay.portlet.journalcontent.util.JournalContentUtil"))

=> some times you also need to access util class which is not have access in template file like StorageEngineUtil. for that you can use below approch..

#set ($util = $portal.getClass().forName("com.liferay.portlet.dynamicdatamapping.storage.StorageEngineUtil").newInstance()) 


HTH.. :))
