Using variables with WordPress translation functions

Keith Devon — Sun, 14 Sep 2014 16:45:50 +0000

OK, why did nobody tell me about this, and why is it not documented! I just found out today that WordPress does some browser detection of its own. I’ve previously relied on other code libraries for this, but maybe now I can use the ‘WordPress Way’. Detecting mobile in WordPress using $is_iphone In wp-includes/vars.php there […]

In my quest to master PHP, I’m going to start investigating some of the bits I’m unfamiliar with, and blogging about them. This morning, I was reading through the excellent “Professional WordPress Plugin Development” by Brad Williams, Ozh Richards and Justin Tadlock (I’ve made a resolution to read a bit every couple of days).
