function book_export_html
7.x book.pages.inc | book_export_html($nid) |
6.x book.pages.inc | book_export_html($nid) |
Generates HTML for export when invoked by book_export().
The given node is embedded to its absolute depth in a top level section. For example, a child node with depth 2 in the hierarchy is contained in (otherwise empty) <div> elements corresponding to depth 0 and depth 1. This is intended to support WYSIWYG output - e.g., level 3 sections always look like level 3 sections, no matter their depth relative to the node selected to be exported as printer-friendly HTML.
Parameters
$nid: An integer representing the node id (nid) of the node to export.
Return value
A string containing HTML representing the node and its children in the book hierarchy.
