Disable the “please update now” message in WP dashboard
Security is indeed a crucial aspect of a website and you should always update all blogs you manage to prevent any risk of hacking. But when working with clients, sometimes you may want to hide the “please update now” message generated by WordPress when a new version is available.
Simply add this code to your functions.php file to hide the message.
if ( !current_user_can( 'edit_users' ) ) {
add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
}

Custom login form with full screen background
Here is a super cool code snippet that your clients will definitely love: a custom login form with a full screen background. Click here for a demo. Once again, the code goes to your functions.php file.
Please note that I left the CSS code “as it” so you can have a look at it, but on a production site you should definitely use an external stylesheet instead.
function login_enqueue_scripts(){
echo '
<div class="background-cover"></div>
<style type="text/css" media="screen">
.background-cover{
background:url('.get_bloginfo('template_directory').'/images/background) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
position:fixed;
top:0;
left:0;
z-index:10;
overflow: hidden;
width: 100%;
height:100%;
}
#login{ z-index:9999; position:relative; }
.login form { box-shadow: 0px 0px 0px 0px !important; }
.login h1 a { background:url('.get_bloginfo('template_directory').'/images/logo.png) no-repeat center top !important; }
input.button-primary, button.button-primary, a.button-primary{
border-radius: 3px !important; background:url('.get_bloginfo('template_directory').'/images/button.jpg);
border:none !important;
font-weight:normal !important;
text-shadow:none !important;
}
.button:active, .submit input:active, .button-secondary:active {
background:#96C800 !important;
text-shadow: none !important;
}
.login #nav a, .login #backtoblog a {
color:#fff !important;
text-shadow: none !important;
}
.login #nav a:hover, .login #backtoblog a:hover{
color:#96C800 !important;
text-shadow: none !important;
}
.login #nav, .login #backtoblog{
text-shadow: none !important;
}
</style>
';
}
add_action( 'login_enqueue_scripts', 'login_enqueue_scripts' );

Disable theme switching
The best way to prevent your clients from switching theme is definitely by disabling theme switching. Paste the following code into functions.php and your clients will not be able to switch themes anymore.
add_action('admin_init', 'slt_lock_theme');
function slt_lock_theme() {
global $submenu, $userdata;
get_currentuserinfo();
if ($userdata->ID != 1) {
unset($submenu['themes.php'][5]);
unset($submenu['themes.php'][15]);
}
}

If you’re building a site for a client and they have some problems with some parts of the dashboard, a good idea is to provide contextual help to the client.
The following hack will allow you to add a custom help messages for the blog admin. As usual, you only have to paste the code into your functions.php file.

// Check we're only on my Settings page
if (strcmp($screen, MY_PAGEHOOK) == 0 ) {
$text = 'Here is some very useful information to help you use this plugin...';
return $text;
}
// Let the default WP Dashboard help stuff through on other Admin pages
return $text;
}
add_action( 'contextual_help', 'my_admin_help' );
