Page templates function similarly to site templates but at the page level. Each page template provides a pre-configured page to reuse. Within a page template, it’s possible to select a theme or layout template, and add applications to the page and configure app preferences. Both sites and site templates can utilize page templates for creating new pages. Click on Sites → Page Templates in the Control Panel to see a list of page templates.
You can edit or delete existing page templates, configure their permissions, or add new page templates. By default, three sample page templates are provided:.
Content Display Page: provides a page preconfigured to display content. It has three auxiliary applications (Tags Navigation, Categories Navigation, and Search) and an Asset Publisher. The most significant aspect of this page is that the Asset Publisher is preconfigured to display any web content associated with this page. This means that you can select any page created from this page template as a Display Page for a web content article. You can choose a display page for a web content article when creating a new web content article or when editing an existing one. When you create a new web content article, a unique (canonical) URL for the web content pointing to this page will be assigned to it.
Wiki: provides a page with three applications related to authoring a wiki. It also has two columns, the main left column with the Wiki application and two right side appss to allow navigating through pages by tags and categories.
Blog: provides a page with three applications related to blogging. It has two columns, the main left column contains the Blogs application and the small right column provides two side apps, Tag Cloud and Recent Bloggers. The Tag Cloud application shows the tags used within the site and allows navigating through the blog entries shown in the main Blogs app.
To add a new page template, click the Add icon (). Then enter a name and description for your template. Leave the Active button enabled. Click Save and then identify your page template in the list. Use the Actions icon () to edit the page template. Clicking the page template’s name opens a new browser window which you can use to configure your new page. Any changes you make are automatically saved so you can close the new browser window once you’re done.
Note that after a new page template has been created, the default permissions are to only allow the creator to use the page template. To give other users access to it, use the Actions menu in the list of templates and choose Permissions. Once you see the matrix of roles and permissions, check the View permission for the role or roles needed to see the page template in the list of available page templates when creating a new page. If you want any user who can create a page to be able to use the page template, just check the View permission for the User role.
To use your template to create a new page, just navigate to your site’s Site Administration dropdown menu and select the Navigation dropdown option. Select the Actions button () for the page or page set you’d like to add a page to and then click the Add Page button. You’ll be able to select a page template and type a name for the new page.
Note that by default, when a site administrator creates pages based on a page template, any future changes to the template are automatically propagated to those pages. Site administrators can disable this behavior by disabling the Inherit Changes selector. Occasionally, propagation for page templates fails due to unintended errors. To learn how to manage a failed page template propagation, visit the Propagating Changes from Site Templates to Sites section of this chapter.
If staging has been enabled, changes to the page template are automatically propagated to the staged page. These changes still need to be approved before the page is published to live. For this reason, the automatic propagation of page template changes to the staged page cannot be turned off and the Inherit Changes selector does not appear.
You’ll learn about staging later in the User’s Guide. For now you’ll look at importing and exporting templates.
Sharing Page Templates
If you want to export a page that uses a page template to a different environment (through a LAR file or remote publication), the template must be exported and imported manually in advance or the import will fail.
To export a page using a page template, use the following process:
- Go to Control Panel → Sites → Page Templates.
- Next to the page template you would like to export, click Actions → Export. This produces a LAR file you can import later.
- On the target environment, go to Control Panel → Sites → Page Templates and create a new page template.
- Next to the new template, click Actions () → Import.
- Upload the LAR file containing the exported page template from step 3.
The page template can now be imported normally to your new environment. For more information on exporting/importing content, visit the Importing/Exporting Pages and Content article.
Next, you’ll examine the tools Liferay Portal provides for exporting/importing content.
