Use the ‘Name’ parameter in your register_sidebar call. E.g., see the following code in the default Twenty Ten theme, line 351. function twentyten_widgets_init() { // Area 1, located at the top of the sidebar. register_sidebar( array( ‘name’ => __( ‘Primary Widget Area’, ‘twentyten’ ), ‘id’ => ‘primary-widget-area’, ‘description’ => __( ‘The primary widget area’, ‘twentyten’ … Read more
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.

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

Adding a page would automatically create a sidebar for it. However – that’s a lot of sidebars. For something tightly coupled with the page content, … Read more
How about native Thickbox with the native jQuery tabs for example: the widget it self is simple and only has a link but one you click on it the thickbox pops up and shows all of the options grouped by tabs: let me know what you think I’ll fetch the code for you.
widget() method is called when widget is rendered, so the style you’re enqueuing are printed in the footer (header is already printed at that time). Even if majority of browser can render styles linked from page body, that’s invalid HTML because, according to HTML standards, unlike scrypts, styles must be placed in page <head>. (Try … Read more
The why part can be found in ticket #24889. Let me quote @azaozz: When support for multi-use widgets was introduced, a lot of widgets got converted from “single” to “multi” at the same time. To keep backward compatibility and not break the existing widgets, there was some conversion code that would set the “single” widgets … Read more
Your problem is that you’re calling the wrong method for generating the name attribute. It should be $this->get_field_name(‘via_cat’) Also, you can use wp_dropdown_categories(), no need to reinvent the wheel: wp_dropdown_categories(array( ‘name’ => $this->get_field_name(‘via_cat’), ‘selected’ => (int)$instance[‘via_cat’], ));
