Moving from Movable Type 3.2 to WordPress 2.3

Julie has decided that she wants to blog a little more frequently. One obstacle to this is that her blog is a spam magnet – or it was until I deleted the Movable Type comment CGIs as a last ditch defense. I’ve had very good results with Akismet on WordPress, so inevitably this meant an upgrade from Movable Type to WordPress. It was only a matter of time before this happened, especially now that I am on WordPress myself. Importing is pretty straight forward. It’s making sure that the permalinks don’t break is the problem. In order to do that you need to make sure that WordPress uses the same numerical id’s that Movable Type used. Which means that you have to hack Movable Type to add an ID field to the exported data, and hack WordPress to use that ID when it creates the new blog entries. Then you do a little mod_rewrite action, and the permalinks should keep on ticking. I’ll now proceed with describing the hacks.

I started with the basic WordPress docs to migrate from Movable Type to WordPress.

Go into the Movable Type 3.2 install and edit lib/MT/ImportExport.pm to add an ID field:

I used Joshua Zader’s modified mt.php and modified it some more so that it would work off of a local file since the MT 3.2 export was over 7MB.

I hope this will save some poor person the time I wasted piecing all this together. Most of the documentation that I googled up was for earlier versions of either Movable Type or WordPress or both. Really, some right thinking, PHP handy person ought to just go in and fix the Movable Type importer and document how to use the Movable Type template in order to make this all work.

Oh, and if you’re going to run multiple WordPress blogs with different url prefixes on a Debian supplied WordPress, then you are going to need this.

New blog theme winner – Gridlock K2

For now I’ve settled on a new theme for the blog, “Gridlock K2“. I’m running the latest RC(3) of K2 and there were some issues with the Gridlock style, some of which were also reported on the Gridlock K2 page, without resolution. Matthew Eernisse, our resident AJAX and CSS wizard for Chandler Server, was kind enough to take a look at the issues that I was having, most notably the sidebar being pushed to the bottom, and the menu rendering oddly. Matthew reduced hours of work to just a few minutes. In order to prevent anyone else from having to do that, here’s a pointer to the “fixed” gridlock.css for the Gridlock K2 style.

New Blog theme

I’m trying out a new blog theme. Let me know what you think.

It’s white for now…

Since I switched the blog to WordPress, I’ve been getting a slow but steady stream of complaints about the white on black theme. I’m going to be experimenting with the colors of the theme, but for now, I’ve switched it to black on white. I like that less, but I understand the readability argument that some commenters have made. The black was particularly nice for photo posts, and I’m sorry to be losing that. If there are any Hemingway theme experts out there I’d be happy for some advice.

Comments and suggestions of all kinds welcome.
