Import b2evolution blog to wordpress

A few months ago I decided that it’s time to say goodbye to b2evolution. I liked the platform, and I’ve been using it for almost 5 years, but development seemed to have stalled, and while I compensated the stillstand for a while by developing my own tools, I grew tired of the fact that everything I wanted is just a click away in WordPress.

All I had to do now was to find a way to feed my b2evolution data into the WordPress scheme. It took a good while until I found someone with a similar task who was willing to share. And to my shame, I have to admit that I don’t know anymore where I got the script from. It proved to be broken anyway, probably because it wasn’t up to date. So I based my importing script on that script, and it worked well. Needless to say that there’s no guarantee that this will still work. And you should (in any case) be sure that you have backed up everything.

What you will need for this setup:

1. A running b2evolution installation
2. A running WordPress installation
3. WordPress Counterize Plugin
4. Database access parameters (see first 20 lines in script)

The script could look nicer, but I wanted to limit it to just one file, so this is what I came up with (again, based on someone else’s work):
