Code Update WP Sub Post

This post is a child post of WordPress Plugin WP Sub Post. To view the parent post, please click here.

There are some changes to the WP Sub Post:

  • Fixed/Added, now child post can be viewed as a single post, with link to the Parent Post instead of displaying blank post with ‘Post not found’ title.
  • Added, CSS class and id to the blockquote of the child post. It would be useful to make a link like http://example.com/parentpost.html#childpostXXX. while XXX is your child post ID.

Two functions that are changed subpost_template() and where_no_parent()
