Localization Specific Logo Image : Liferay Portal

Often there are requirements to show customized logo image according to portal's current locale. In Liferay Portal there is no way achieve this but locale specific logo can applied by using the theme.

In theme, portal_normal.vm contains the following statement to display logo -

<a href="$company_url" title="#language("go-to") $company_name">
<span>$company_name</span>
</a>

Here you can place check for the locale and accordingly change the logo image -

<a href="$company_url" title="#language("go-to") $company_name">
#if($locale == "en_US")
<img src="englishlogoimage" />
#else
<img src="spanishlogoimage" />
#end
</a>

but now you can't manage the logo from the community settings as image urls are hardcoded in the theme. To make it manageable you can use web content to render the logo image.

Any comments or suggestions will be appreciated ....

 

Community Specific Locale Liferay Portal (Per Community BasisLocalization)

Liferay provides us with fine grained built-in localization features. In Liferay Portal one can apply localization on per user basis. But how to apply default locale to a Community, Liferay doesn’t provide any such functionality but it can be implemented using Portal Properties Hook.

So case is, portal instance have more than one Community and we need to apply a default language setting for one Community that is different from other Communities. To achieve this implement an Event Hook for servlet.service.events.pre.

Following is the step by step description to achieve this functionality-

1.  Create a portal properties hook and choose the servlet.service.events.pre Event

2.  Create a new class say SampleClass by extending the com.liferay.portal.kernel.events.Action


3.  Now en_US locale will be applied to LONG_GROUP_ID Community.

Communities in Liferay Portal

Community is the group of users who shares the same interests. Each community have its own private and public pages in liferay portal.

Types of Communities:

There are 3 types of communities Liferay Portal. These are as follows-

1. Open: Open Community allows users to join and leave a Community whenever they want to.


2. Restricted: In Restricted Community user first have to make request for the membership. It means Restricted Community requires administrator or owner approval to add users to the community or to remove users from the community but users have the ability to leave the community.


3. Private: In case of Private Community there is no way to join or make request for membership.Both  Community Owner and Community administrator can assign a user to the Community.

So basic difference between Restricted and Private Community is that, in case of Restricted Community membership is subject to administrator approval but in case of Private Community there is no way of joining the Community.
