WP-Footnotes to YAFootnotes
While moving Darkmatter journal from WP-Footnotes plugin to YAFootnotes plugin (custom tweaked, moved because YAFootnotes was easier for writers/reviewers) we bumped into a problem: a lot of older posts used the old syntax. We had three choices:
- Leave WP-Footnotes plugin for older posts (different look and feel, one more plugin using up resources)
- Change posts by hand (lots of posts)
- Create a script to update all older posts who used old syntax.
I choose to create a script. After it was done I saw that it could be made into WordPress plugin with minimal work, so: download WP-Footnotes to YAFootnotes
Update:
It's available at WordPress plugin repository too: WP-Footnotes to YAFootnotes.

Happy to see that my plugin was helpful!
