Add elements to a page before it is rendered.

Use this hook when you want to add elements at the page level. For your additions to be printed, they have to be placed below a top level array key of the $page array that has the name of a region of the active theme.

By default, valid region keys are 'page_top', 'header', 'sidebar_first', 'content', 'sidebar_second' and 'page_bottom'. To get a list of all regions of the active theme, use system_region_list($theme). Note that $theme is a global variable.

If you want to alter the elements added by other modules or if your module depends on the elements of other modules, use hook_page_alter() instead which runs after this hook.

Parameters

$page: Nested array of renderable elements that make up the page.
