Put code into body tags near top, using a plugin

by

How do I use a plugin to put this inside the body of every page on my WP site, for facebook integration. (Yes, I know other plugins can do it, but I want to do it myself.) Facebook recommends as close to the top of the lead body tag as possible.

Thanks!

<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=99999999999";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

Put that script into a file somewhere in your theme folder. Include it using the following code in your theme’s functions.php file:

<?php
function wpa_65602_enqueue_scripts() {
     wp_enqueue_script( 'facebook', get_bloginfo( 'template_url' ) . '/path/to/script.js' );
}
add_action( 'wp_enqueue_scripts', 'wpa_65602_enqueue_scripts' );
