WordPress ist ein großartiges Tool für kleine Homepages und professionelle Websites. Noch dazu ist es kostenlos und quelloffen. Aber es gibt weitaus mehr Einsatzmöglichkeiten. Zum Beispiel als kleines Intranet-Wiki oder für den Digital Signage Bereich.

Manchmal ist es dann notwendig alle WordPress-Brandings inklusive Logos und Links von der Login-Seite und aus dem Backend zu entfernen um ein Whitelabel zu schaffen. Folgendes Script, welches man entweder im Theme oder in einem eigenen Plugin unterbringen kann, erledigt das:

<?PHP
 
/*
	Configure login
*/
define('SIGNPRESS_CHANGE_LOGIN_LOGO_PATH',true);
define('SIGNPRESS_LOGIN_LOGO_PATH','/wp-content/your_logo.png');
define('SIGNPRESS_LOGIN_LOGO_WIDTH',300);
define('SIGNPRESS_LOGIN_LOGO_HEIGHT',150);
define('SIGNPRESS_CHANGE_LOGIN_LOGO_TITLE',true);
define('SIGNPRESS_LOGIN_LOGO_TITLE','My Logo Title');
define('SIGNPRESS_CHANGE_LOGIN_LOGO_LINK',true);
define('SIGNPRESS_LOGIN_LOGO_LINK','http://www.mypage.com/');
 
/*
	Configure admin
*/
define('SIGNPRESS_REMOVE_WP_FROM_ADMIN_BAR',true);
define('SIGNPRESS_REMOVE_WP_ADMIN_WIDGETS',true);
define('SIGNPRESS_REMOVE_WP_WELCOME_PANEL',true);
define('SIGNPRESS_REMOVE_WP_ADMIN_HELP_TAB',true);
 
/*
	Clear, change and remove the WordPress soul :-(
*/
 
// Change login logo
if(SIGNPRESS_CHANGE_LOGIN_LOGO_PATH){
	add_action('login_enqueue_scripts', function () {
		$html = '';
		$html.= '<style type="text/css">';
			$html.= 'body.login div#login h1 a {';
				$html.= 'background-image: url('.SIGNPRESS_LOGIN_LOGO_PATH.');';
				$html.= 'background-size: '.SIGNPRESS_LOGIN_LOGO_WIDTH.'px auto;';
				$html.= 'width:'.SIGNPRESS_LOGIN_LOGO_WIDTH.'px;';
				$html.= 'height:'.SIGNPRESS_LOGIN_LOGO_HEIGHT.'px;';
			$html.= '}';
		$html.= ' </style>';
		echo $html;
	});
}
 
 
// Change login logo link
if(SIGNPRESS_CHANGE_LOGIN_LOGO_LINK){
	add_filter( 'login_headerurl', function () {
		return SIGNPRESS_LOGIN_LOGO_LINK;
	} );
}
 
 
// Change login logo title
if(SIGNPRESS_CHANGE_LOGIN_LOGO_TITLE){
	add_filter( 'login_headertitle', function () {
		return SIGNPRESS_LOGIN_LOGO_TITLE;
	} );
}
 
 
// Remove WordPress logo from admin bar
if(SIGNPRESS_REMOVE_WP_FROM_ADMIN_BAR){
	add_action('wp_before_admin_bar_render', function () {
		global $wp_admin_bar;
		$wp_admin_bar->remove_menu('wp-logo');
	}, 0);
}
 
 
// Remove WordPress news widgets from backend
if(SIGNPRESS_REMOVE_WP_ADMIN_WIDGETS){
	add_action( 'admin_init', function () {
		remove_meta_box('dashboard_incoming_links', 'dashboard', 'normal' );
		remove_meta_box('dashboard_plugins', 'dashboard', 'normal' );
		remove_meta_box('dashboard_primary', 'dashboard', 'normal' );
		remove_meta_box('dashboard_secondary', 'dashboard', 'normal' );
		remove_meta_box('dashboard_incoming_links', 'dashboard', 'normal' );
		remove_meta_box('dashboard_quick_press', 'dashboard', 'side' );
		remove_meta_box('dashboard_recent_drafts', 'dashboard', 'side' );
		remove_meta_box('dashboard_recent_comments', 'dashboard', 'normal' );
		remove_meta_box('dashboard_right_now', 'dashboard', 'normal' );
		remove_meta_box('dashboard_activity', 'dashboard', 'normal' );
	} );
}
 
 
// Remove WordPress welcome panel
if(SIGNPRESS_REMOVE_WP_WELCOME_PANEL){
	remove_action('welcome_panel', 'wp_welcome_panel');
}
 
 
// Remove admin help tab
if(SIGNPRESS_REMOVE_WP_ADMIN_HELP_TAB){
	add_filter( 'contextual_help', function ($old_help, $screen_id, $screen){
		$screen->remove_help_tabs();
		return $old_help;
	}, 999, 3 );
}
