The following are the baseline variables available to all template files. They are generated through the preprocessor function, template_preprocess Drupal 6 or template_preprocess Drupal 7. Variables specific to the template are documented inside the file.

New Variables available in D7

$attributes_array

$title_attributes_array

$content_attributes_array

$classes_array

Array of html class attribute values. It is flattened into a string within the variable $classes.

$title_prefix

An array containing additional output populated by modules, intended to be displayed in front of the main title tag that appears in the template.

$title_suffix

An array containing additional output populated by modules, intended to be displayed after the main title tag that appears in the template.

$id: The placement of the template. Each time the template is used, it is incremented by one.
$zebra: Either "odd" or "even". Alternate each time the template is used.
$directory: The theme path relative to the base install. example: "sites/all/themes/myTheme"
$is_admin: Boolean returns TRUE when the visitor is a site administrator.
$is_front: Boolean returns TRUE when viewing the front page of the site.
$logged_in: Boolean returns TRUE when the visitor is a member of the site, logged in and authenticated.
$db_is_active: Boolean returns TRUE when the database is active and running. This is only useful for theming in maintenance mode where the site may run into database problems.
$user: The user object containing data for the current visitor. Some of the data contained here may not be safe. Be sure to pass potentially dangerous strings through check_plain.
