[WordPress] What do you include in YOUR functions.php file?

[mikes02]

I’m always curious what others include in every functions.php file when they build out a site, here are some defaults for me, some may be outdated by now:

<?php
// REMOVE JUNK FROM HEAD
remove_action('wp_head', 'feed_links_extra', 3); // Displays the links to the extra feeds such as category feeds
remove_action('wp_head', 'feed_links', 2); // Displays the links to the general feeds: Post and Comment Feed
remove_action('wp_head', 'rsd_link'); // Displays the link to the Really Simple Discovery service endpoint, EditURI link
remove_action('wp_head', 'wlwmanifest_link'); // Displays the link to the Windows Live Writer manifest file.
remove_action('wp_head', 'index_rel_link'); // index link
remove_action('wp_head', 'parent_post_rel_link'); // prev link
remove_action('wp_head', 'start_post_rel_link'); // start link
remove_action('wp_head', 'adjacent_posts_rel_link_wp_head'); // Displays relational links for the posts adjacent to the current post.
remove_action('wp_head', 'wp_generator'); // Displays the XHTML generator that is generated on the wp_head hook, WP version

// ADD FAVICON TO HEADER 
function blog_favicon(){echo '<link rel="Shortcut Icon" type="image/x-icon" href="'.get_bloginfo('template_directory').'/favicon.ico">';}
add_action('wp_head', 'blog_favicon');

// REMOVE WORDPRESS DEFAULT LOGIN ERROR MESSAGES AND ADD CUSTOM
add_filter('login_errors',create_function('$a', "return 'Login Information Incorrect. Please Try Again.';"));

// REPLACE DEFAULT WORDPRESS LOGIN LOGO WITH CUSTOM LOGO
function custom_login_logo() {echo '<style type="text/css">h1 a { background: url('.get_bloginfo('template_directory').'/images/logo-login.png) no-repeat}</style>';}
add_action('login_head', 'custom_login_logo');

// ADD TITLE TO LOGIN LOGO
function change_wp_login_title(){return 'Title Here';}
add_filter('login_headertitle', 'change_wp_login_title');

// ADD POST THUMBNAILS
if(function_exists('add_theme_support')){add_theme_support('post-thumbnails');}

// MENUS
if(function_exists('add_theme_support')){add_theme_support( 'menus' );}

// Customize the footer in admin area
function wpfme_footer_admin () {
    echo '<a href="http://urlhere.com/" target="_blank">Name Here</a>';
}
add_filter('admin_footer_text', 'wpfme_footer_admin');

// Enqueue Main Stylesheet
function main_styles()
{
    wp_enqueue_style( 'style', get_stylesheet_uri() );
}
add_action( 'wp_enqueue_scripts', 'main_styles' );
