Parameters

$type: Specifies what will show up in the link: the twitter icon, the twitter icon and text, or just text. Pass 'icon' to show just the icon, 'icon_text' to show the icon and text, and 'text' to show just the text. Required if display options for nodes are set to 'none' on the settings page.

$format: A string representing the tweet text, optionally with the case-insensitive tokens [url] and [title]. If not passed, the format from the settings page will be used.

$nid: The NID of the node for which the twitter link should be constructed.

$q: The absolute URL of the page for which the twitter link should be constructed. If this is not the current page, the title must be set manually, or it will be incorrect.

Return value

A themed link to post the specified or current page to twitter.
