Overview
HiFi is a head injection and foot injection plugin (or head include, foot include, head insert, foot insert, what ever you want to call it). It basically allows you to inject <script>, <style>, <meta> and any other code you want into the head and foot areas of your posts and pages. The code injected is page-specific, this means that only the pages you want code inserted into will be affected.
This plugin is most useful when you have specific functionality that needs to be added on a per-post/page basis.

Works perfectly! 2015 and WP 4.1
by JeremyBorum·11 years ago
Adds fields for header and footer inserts below the page content of individual pages. Perfect!
Great plugin but one feature missing
by cedrix·11 years ago
This plugin works very well.
I just think it is too bad it do’est allow to choose a default head/header injection and that it is only on a per-post system.
Such a useful plugin

Was a little put off with the “This plugin has not been updates in 2 years” thing but have no fear!
I am using 3.8 and it works perfectly.
Such an amazingly useful plugin!
LOVE IT!!!!
Works on 3.5.2

Still works like a charm.
Don’t be fooled by “This plugin hasn’t been updated in over 2 years….”
Works in 3.5.1
by japheth·13 years ago
Tested to work in WordPress 3.5.1 with Headway 3.4.8. If you use CloudFlare with your site and discover that injected JavaScript does not seem to work, add data-cfasync=”false” to the opening script tag: http://stackoverflow.com/a/10611827
