removing wordpress generated code from the head section?

1 Views

Specifically, I’m talking about the following which gets added automatically:

1) <script type='text/javascript' src='http://mysite.com/wp-includes/js/l10n.js?ver=20101110'></script>

2) <script type="text/javascript">
//<![CDATA[
var _wpcf7 = { cached: 1 };
//]]>
</script>

3) <link rel="stylesheet" href="http://disqus.com/stylesheets/theme/disqus.css?v=2.0" type="text/css" media="screen" />

4) 

<style type='text/css'> 
#wpadminbar .quicklinks li#wp-admin-bar-stats {height:28px}
#wpadminbar .quicklinks li#wp-admin-bar-stats a {height:28px;padding:0}
#wpadminbar .quicklinks li#wp-admin-bar-stats a img {padding:4px 11px}
</style>

Not sure about #1, I know #2 is generated by the Contact Form 7 plugin, #3 is Disqus, and #4 is from the new admin bar in 3.1 and although I added show_admin_bar( false ); to my functions file, the styles still show up in my head section. Anyway to get rid of all or at least some of these?

  1. 1) Normally not (that’s the translation mechanism offered for javscript strings), but you can probably de-register that l10n script. But be warned that some plugins and the site might not work as intended any longer.

    2) Yes, by uninstalling the contact form 7 plugin.

    3) Yes, by removing the disqus plugin.

    4) If disabling the admin bar did not work, please report this as a bug in wordpress trac. I assume it left’s over a registered hook to be removed, but that’s just an assumption.

  2. 4) Plugins > WordPress.com Stats. Uncheck Admin Bar. Unfortunately, it doesn’t saved but you can easily fix it.

-                               if ( isset($_POST['admin_bar']) )

                                $options['reg_users'] = isset($_POST['reg_users']) && $_POST['reg_users'];

    … or use this until someone report the bug:

    
add_action( 'plugins_loaded', 'remove_stats_admin_bar_head' );
    function remove_stats_admin_bar_head() {
        remove_action( 'wp_head', 'stats_admin_bar_head', 100 );
    }

  3. You can de-register #1 by doing, but as hakre said it probably best to keep it;

    function my_removal_thang() {
wp_deregister_script( 'l10n' );
}
add_action('init', 'my_removal_thang');
