ExtreaHead plugin for Wordpress

The ExtraHead plugin makes it easy to insert arbitrary code into the header of any page on a per-page basis. Just create a custom field with the key “extreahead” and the value will be inserted, untouched, into the header.

Sometimes you just want a little custom CSS or javascript on a page.

I was a bit surprised that nothing like this was easily found on the Wordpress codex or via Google, so I took an existing plugin (HeadMeta) and tweaked it to my needs.

ExtreaHead 1.1

The plugin is absurdly simple, in fact it consists of one file:

< ?

function extrahead() {
    global $posts;

    // only act when viewing a single post or a page. Else, exit.
    if ( !(is_single() || is_page() ) ) return;

    // Get the post
    $post = $posts[0];

    // Get the keys and values of the custom fields:
    $id = $post->ID;
    $data = get_post_meta($id, 'extrahead', false);

    if (is_array($data)) {
        print "\n";
        foreach ($data as $line) {
            print "$line\n";
        }   
        print "\n";
    }

}

// Hook into the Plugin API
add_action('wp_head', 'extrahead');

?>

  1. [...] ExtraHead, a tiny plugin for Wordpress. I’m sure this functionality exists elsewhere in the Wordpress world, but I couldn’t find it after 10 minutes of Googling so I wrote a plugin. ExtraHead just makes it easy to insert arbitrary code into a page header, on a page-by-page basis. Just add a custom field with the key extrahead and whatever code you want in the header as the value. [...]
