function pager_find_page in Drupal 7

Same name and namespace in other branches

1. 8 core/includes/pager.inc \pager_find_page()

Returns the current page being requested for display within a pager.

Parameters

$element: An optional integer to distinguish between multiple pagers on one page.

Return value

The number of the current requested page, within the pager represented by $element. This is determined from the URL query parameter $_GET['page'], or 0 by default. Note that this number may differ from the actual page being displayed. For example, if a search for "example text" brings up three pages of results, but a users visits search/node/example+text?page=10, this function will return 10, even though the default pager implementation adjusts for this and still displays the third page of search results at that URL.
