You can use wp_get_sidebars_widgets() with an “on demand” filter callback. This means we’re adding the filter callback, right before the call to the function and then remove right inside the callback again. This allows us, to use it only once. It also means, that we need to set it right before the call to wp_get_sidebars_widgets() … Read more
The parameters are given (as an array) as the first argument provided to the widget method. The second argument, $instance, holds the options for that particular instance of the widget.

Sure, you can do this. It sounds like it would make more sense to add a protected forum to your installation though… but here’s how you would do it: // Create the function to output the contents of our Dashboard Widget function iframe_dashboard_widget_function() { // Display whatever it is you want to show echo ‘<iframe … Read more
As the comment says, you should validate the values of the new instance. What happens if one of these values is invalid? You can either set a predefined default value or use the value from the old instance, because that must be valid. So a very simple update code could look like this: function update( … Read more
http://codex.wordpress.org/Function_Reference/unregister_widget add something like this to functions.php: if (!function_exists(‘my_unregister_default_wp_widgets’)) { function my_unregister_default_wp_widgets() { unregister_widget(‘WP_Widget_Calendar’); unregister_widget(‘WP_Widget_Recent_Posts’); } add_action(‘widgets_init’, ‘my_unregister_default_wp_widgets’, 1); } Also… you can look at the http://codex.wordpress.org/Widgets_API examples to see how you can extend the WP_Widget class to create custom widgets that you want.
Just register another widget area. Don’t take the name sidebar literally, you can use the fields anywhere on your page. In your theme’s functions.php: add_action( ‘after_setup_theme’, ‘register_multiple_widget_areas’ ); function register_multiple_widget_areas() { register_sidebar( array( ‘name’ => ‘Sidebar’, ‘id’ => ‘sidebar’, ‘description’ => ‘describe the function of the box.’ ) ); register_sidebar( array( ‘name’ => ‘Header’, ‘id’ … Read more
