How to identify a Page Template using Freemarker

Issue

• I need to identify if the current page is a page template or not, using Freemarker from the applied theme.
• Is there a method similar to Layout.isPublicLayout() to achieve this?

Environment

• Liferay DXP 7.2
• Liferay DXP 7.3

Resolution

• Unfortunately there is no direct method available such as isPublicLayout(), however, we can use the  fetchLayoutPageTemplateEntryByPlid method to achieve this.
• Here is a code example to do it:

  <div id="wrapper" role="main">
     <#assign layout = themeDisplay.getLayout()/>
     <#assign plid = layout.getPlid() />
  
     <!-- Note that the page template could be a Draft -->
     <#if layout.getClassNameId() != 0>
        <#assign realPlid = layout.getClassPK()/>
     <#else>
        <#assign realPlid = plid/>
     </#if>
  
     <#assign layoutPageTemplateEntryLocalService = serviceLocator.findService("com.liferay.layout.page.template.service.LayoutPageTemplateEntryLocalService") />
     <#if layoutPageTemplateEntryLocalService.fetchLayoutPageTemplateEntryByPlid(realPlid)??>
        Template
     <#elseif layout.isPublicLayout() >
        Public
     <#else>
        Private
     </#if>
  </div>
