Saul Cozens has done a wonderful thing. He's written a WordPress plugin which allows you to integrate content from the new gov.uk site within WordPress pages. You add a WordPress shortcode, of the form:
It pulls in the corresponding JSON data - which is really just a case of adding .json on the end of the URL - and plonks it into your WordPress page. So far, so not tremendously complicated.
Here's the good bit. No, sorry, the fantastic bit. Not only does it plonk the text in, it can also plonk forms into place. And keeps them active as forms. Yes - actual, working forms.
My screenshot above is taken from my test server: no offence Saul, but I'm not putting a v0.1 alpha plugin on my company site! - but it shows me successfully embedding the Student Finance Calculator 'quick answer' form within my current blog theme, and sending data back and forth. Sure, the CSS needs a little bit of work... but Saul's concept is proven.
