Clean up output added via wp_head()

by

The question:

I know that wp_head() is important, but using it injects so much crap into the header. I’d like to get it out and just add manually the 2-3 line of code that I need.

But, there is certain code added by WordPress that I want to keep: 

<meta name="description" content="" />
<meta name="keywords" content="" />
<link rel='canonical' href='http://jlecologia.com/cms/' />
...
<meta http-equiv="Content-Language" content="fr-FR" />

How can this be generated for me? (Something like bloginfo('name') will be fine for me.)

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

You can remove some of the header stuff with the following.

// remove unncessary header info
function remove_header_info() {
    remove_action('wp_head', 'rsd_link');
    remove_action('wp_head', 'wlwmanifest_link');
    remove_action('wp_head', 'wp_generator');
    remove_action('wp_head', 'start_post_rel_link');
    remove_action('wp_head', 'index_rel_link');
    remove_action('wp_head', 'adjacent_posts_rel_link');
}
add_action('init', 'remove_header_info');

The default installation does not include stuff like meta keywords, so that is either a theme or plugin that you are using.

Method 2

Have a look here: http://codex.wordpress.org/Plugin_API/Action_Reference/wp_head

Essentially you need to add an action for the wp_head hook, and (probably) remove the other actions that have been associated with the wp_head hook.
