I don’t think using ‘init‘ or ‘admin-init‘ makes much of a difference. It means it’ll either run on init only when in the admin area or on init in general. Either way, init happens and the function doesn’t seem very intensive. Using ‘admin-init‘ could possibly increase front-end performance though, as the function would not be running on the front-end. Not sure if the performance difference would be noticeable though.

It looks, to me, like it’s a case of 6 of 1 or half a dozen of the other. Using either method, the function will run at the init stage.

Thanks for the link and quote. I find the Wordpress codex to be a useful resource which I use regularly.

Cheers,

From: http://codex.wordpress.org/Query_Overview:

“So if you want to modify rewrite rules, you will need to call $wp_rewrite->flush_rules() to force them to recalculate. You’ll need to do this in your plugin’s init action, so that it happens early enough in the process. ”

I’ll look into the call to flush_rewrite_rules.

I’ll be writing a few more posts discussing custom rewrite rules in Wordpress, how to work with them and a few advanced uses. These may be followed up with a plugin.

Cheers,
Matt.

I’ll check into flush_rules() and optimise the code accordingly.

Cheers and thanks again,
Matty.

p.s., i love your blog design!

Please tweet some URLs where you use this tut. I’d be keen to see your implementation of it.

Cheers and thanks again,
Matt.
