Customizing the WordPress Admin Dashboard with Code Snippets

Customizing the WordPress Admin Dashboard

Custom Code Solution

Add these code snippets to your theme's functions.php file or in a site-specific plugin.

Remove default dashboard widgets:

function remove_default_dashboard_widgets() {
    remove_meta_box('dashboard_quick_press', 'dashboard', 'side');
    remove_meta_box('dashboard_primary', 'dashboard', 'side');
    remove_meta_box('dashboard_right_now', 'dashboard', 'normal');
    remove_meta_box('dashboard_activity', 'dashboard', 'normal');
}
add_action('admin_init', 'remove_default_dashboard_widgets');

Add a custom welcome widget:

function add_welcome_dashboard_widget() {
    wp_add_dashboard_widget(
        'custom_welcome_widget',
        'Welcome to Your Dashboard',
        'display_welcome_widget_content'
    );
}
add_action('wp_dashboard_setup', 'add_welcome_dashboard_widget');

function display_welcome_widget_content() {
    echo '<h3>Welcome ' . wp_get_current_user()->display_name . '!</h3>';
    echo '<p>Here are some quick links:</p>';
    echo '<ul>
        <li><a href="' . admin_url('post-new.php') . '">Create New Post</a></li>
        <li><a href="' . admin_url('upload.php') . '">Media Library</a></li>
        <li><a href="' . admin_url('users.php') . '">Manage Users</a></li>
    </ul>';
}

Customize dashboard colors and styles:

function custom_admin_css() {
    echo '<style>
        #wpadminbar, #adminmenu, #adminmenuback, #adminmenuwrap {
            background: #2c3338; /* Change main color */
        }
        #dashboard-widgets .postbox {
            background: #fff;
            border-radius: 4px;
            box-shadow: 0 1px 3px rgba(0,0,0,0.1);
        }
        .welcome-panel {
            background: #f0f6fc;
        }
    </style>';
}
add_action('admin_head', 'custom_admin_css');

Rearrange dashboard columns layout:

function set_dashboard_columns() {
    return array(
        'dashboard-primary' => array('side', 'core'),
        'custom_welcome_widget' => array('normal', 'core'),
    );
}
add_filter('dashboard_screen_layout_columns', 'set_dashboard_columns');
