Hook to override language.properties

Liferay has more than 43 languages available.
Using Hook we can add new language messages or even can modify existing one.
Steps :

Modify liferay-hook.xml :

        <hook>        <portal-properties>portal.properties        </portal-properties>        <language-properties>     content/Language_en.properties     </language-properties>        <language-properties>     content/Language_hi_IN.properties     </language-properties>     </hook>



Create folder within hooks\myfirsthook-hook\docroot\WEB-INF\src\content

Create file Language_en_US.properties and Language_hi_IN.properties .

Language_en.properties

        what-is-your-lucky-number=What is ur Lucky Number ?

        what-is-ur-girl-friend-name=What is ur girl friend Name?

Language_hi_IN.properties:

       what-is-your-lucky-number=आपका पहला Lucky नंबर क्या था?

     what-is-ur-girl-friend-name=आपके पहले girlfirnd का नाम क्या था?

Portal.properties.

locales=hi_IN,en_US

     users.reminder.queries.questions= what-is-your-lucky- number,what-is-ur-girl-friend-name

Deploy Hook.

So new messages get display :

Liferay JSP Hook Creation
-------------------------------------------------------------------------------------

To view it require latest version of firefox and adobe flash player. -------------------------------------------------------------------------------------

         LIFERAY HOOKS

             Advance-I

Hook to override jsp files :

This is most simple hook.

Task: We are going to modify Terms of use page when user gets Login first time.

Steps

Create directory inside our hook : liferay-plugins-sdk-6.1\hooks\myfirsthook-hook\docroot\META-INF\custom_jsps

Modify liferay-hook.xml file.

       `<hook>             <custom-jsp-dir>             /META-INF/custom_jsps             </custom-jsp-dir>         </hook>`

terms_of_use.jsp file is present within tomcat\webapps\root\html\portal.

Create Similar mirror folder structure within /META-INF/custom_jsps in our hook..

Create hooks\myfirsthook-hook\docroot\META-INF\custom_jsps\html\portal folder.

Now copy tomcat\webapps\root\html\portal\terms_of_use.jsp and put it into \myfirsthook-hook\docroot\META-INF\custom_jsps\html\portal in hook folder.

Edit the terms_of_use.jsp as u like.

Now deploy hook.

Create new user and login to liferay, modified tems_of_use.jsp will get displayed.

After deployment of hook old jsp will get rename to terms_of_use.portal and new one get placed at their place.

Note: Don’t use different hook to override same jsp as liferay will not recognizes which one to use.
