At OrangeValley, we’re currently working on migrating a large Dutch blog network over from it’s own proprietary system to a WordPress Multi User install, one of our more serious WordPress MU development projects. There’s quite a few things about WordPress MU that I like, but what I like most is, well, that’s it’s WordPress :)
For this project I needed some fairly simple things, that I could have used other plugins for but I wanted them to be simpler and cleaner than most plugins could do for me. One of those things was I needed to show an image for each post on the index and archive pages, if there was one, and wanted to be able to add a certain class to that.
So I wrote a small plugin called WordPress MU Attached Image, which does just that. It’s use is simple, you download the attached image plugin, upload it to your mu-plugins folder, and use this in the loop in your theme:
Or, as in my case:
Now this plugin will work in a normal WordPress install too, but that’s not what I wrote it for :)
Another thing I badly wanted was a plugin that would force the same permalink structure on all new blogs, and disallowed blog admins from changing them. This plugin does that, and immediately shows why I love WordPress MU development: the power it has to easily change things on tons of blogs at the same time is very cool.
It works like this: you download the fixed permalink plugin, make sure that on line 11, this reflects the permalink structure you want:
$yst_permalink_structure = '/%postname%/';
And you upload it to your mu-plugins folder. Voila: you’re now the only one who can change permalink structures, and all new blogs will automatically have the right permalink structure.
You can expect more posts on WordPress MU in the coming weeks, as I dive deeper into the system. In the mean while, if you have a WordPress MU development project you’d like us to take on, contact me!
