Hi,
attached is a preliminary version of wp_list_pages which supports
hierarchies. The file if a diff created with cvs diff -U3 filename
It supports the following options:
- child_of: Only select childern of the specified page ID. - default: 0
- optiondates: display the date the page was created. - default: 0
- modifieddate: if optiondates is set display the date the page was modified. - default: 0
- date_format: use this date format instead of the one from the options. - default: ''
- depth: only recurse this deep, if set to 0 display all levels. - default:0.
_ sort_column: Sort output by this column - default: post_title
- sort_order: specify sort order - default:ASC
Feedback welcome.
Adi
