Jtags is a plugin for WordPress that allows you to call php functions from your posts using ordinary XML-like tags. A jtag is a series of name=value pairs where the first one listed (by convention) is the function name to call and the rest are parameters.
At its heart, it’s a simple substitution routine. You write a jtag and it runs some code, does some formatting or whatever else you want, and outputs the result in place of where you had the jtag originally.
