Add More to the “Howdy” Line

Want to put something else besides “Howdy” and “Log Out” in the upper right hand corner? It’s easy!

add_filter('admin_user_info_links', 'add_user_id_to_top');
function add_user_id_to_top($links) {
	global $current_user;
	get_currentuserinfo();
	$links[] = ' | User ID: '. $current_user->ID;
	return $links;
}

In this example, we’re adding the current user’s ID to the top. I also like adding the blog ID up there when working on a WordPress network.

add_filter('admin_user_info_links', 'add_site_id_to_top');
function add_site_id_to_top($links) {
	global $blog_id;
	$links[] = ' | Site ID: '. $blog_id;
	return $links;
}

Change “Howdy” to Another Greeting

If “Howdy” just ain’t your thing, use this to change it to something more your style.

add_filter('admin_user_info_links', 'change_howdy');
function change_howdy($links) {
	$links[5] = str_replace('Howdy', 'Greetings', $links[5]);
	return $links;
}

Add Featured Image Thumbnail to Posts Page

Customize the information that is displayed on the ‘posts’ page

Adding a column labeled “Thumbnail” (and delete the “Comments” column).

add_filter( 'manage_edit-post_columns', 'set_columns' );
function set_columns($columns) {
	$columns['thumbnail'] = 'Thumbnail';
	unset( $columns['comments'] );
	return $columns;
}

Now we need to tell WordPress what to do with this new “Thumbnail” space. Here, we’re checking for the existence of a featured image and displaying it, or noting that there is no thumbnail.

add_action( 'manage_posts_custom_column', 'fill_columns' );
function fill_columns($column) {
	global $post;
	switch($column) {
		case 'thumbnail' :
			if (has_post_thumbnail($post->ID))
				echo get_the_post_thumbnail($post->ID, array(50, 50));
			else
				echo '<em>no thumbnail</em>';
		break;
	}
}

Customize the Favorites Menu

Ever use that favorites menu up by the “Howdy” greeting? I never really did until I started customizing the options.

One of my favorites is adding a link to the master options page (wp-admin/options.php)

add_filter('favorite_actions', 'custom_favorites');
function custom_favorites($actions) {
		$actions['options.php'] = array('All Settings', 'unfiltered_html'); // this line adds an item
		return $actions;
}

Or, remove the menu entirely

add_filter('favorite_actions', 'remove_favorites');
function remove_favorites($actions) {
		$actions = array(); 
		return $actions;
}

Change “Privacy Mode” Warning Text

If you want to see something other than “Search Engines Blocked” when, well, search engines are blocked, you can use this to customize the text

add_filter('privacy_on_link_text', 'change_privacy_text');
function change_privacy_text() {
	_e('Privacy Mode Enabled');
};

Change Admin Footer Text

If you need to customize the WordPress administration area, you’ll find this useful.

add_filter('admin_footer_text', 'left_admin_footer_text_output'); //left side
function left_admin_footer_text_output($text) {
    $text = 'How much wood would a woodchuck chuck?';
    return $text;
}

add_filter('update_footer', 'right_admin_footer_text_output', 11); //right side
function right_admin_footer_text_output($text) {
    $text = "That's purely hypothetical.";
    return $text;
}
