book_export_html
- Versions
- 4.7 – 5
book_export_html($nid,$depth)- 6 – 7
book_export_html($nid)
This function is called by book_export() to generate HTML for 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.
