Gallery2:Themes:Reference:Variables

You can view all variables available on a particular page by turning on debug mode.

Some variables are made available in all themes / template files. Among these are:

isEmbedded -- True if site is viewed embedded in another application; false if viewed standalone.

User Information

Information about the active user:

$user.userName, $user.fullName, $user.email, ... all user attributes
$user.isGuest, $user.isRegisteredUser, $user.isAdmin which help to create page content that is only visible to logged in users (registeredUser) or admins, or guests.

Example code for G2 .tpl files:

 {if $user.isRegisteredUser}
 Welcome {$user.userName}!
 {else}
 Welcome, guest!
 {/if}

$theme.item.id is the id (unique identifier) of the item shown in the current page. in photo.tpl, $theme.item.id is the id of the current data item (e.g. a photo)
Generally, you have access to all members of GalleryItem, e.g. $theme.item.canContainChildren is true for albums, false for photos and other data items.
$theme.item.title, $theme.item.summary, $theme.item.description are available as well. Don't forget to use the |markup modifier when using them.
Look at the smarty debug console to a list of all available variables.
