If you run into problems like:

PHP Fatal error: Call to a member function register() on a non-object in ../wp-includes/widgets.php

You may need to adjust your registration code to wait until the WordPress init is completed, like this:

function register_My_RSS_Widget(){
register_widget('My_RSS_Widget');
}
add_action('init', 'register_My_RSS_Widget', 1)

TZS,
with a plugin you can use

add_action( 'widgets_init', create_function('', 'return register_widget("My_RSS_Widget");') );

HI!

Nice tut! But, i have a question. When i try to make a plugin by the above code, the WP has dropped an error, such as "register is not a member class" or something else like this...

So how can i make a widget by the API in a plugin file? I have to use add_action() ot register_widget_controller() or what?

Thanks for the help!

I figured it out, my actual code execution that I would place inside the function widget() area I actually have *above* the class and called by function widget() {} .. call it My_RSS(){ ..

Now if I go and hardcode it on the site someplace I can do that.

You don't have to call widget(). Wordpress does it for you if the widget is active.

How would I call that function" function widget($args, $instance) " ?

in 2.5ish it was easy just to do and it would execute the function.

Can you please tell me how to create a widget to show a drop-down list of authors in a multi-author blog using the WP 2.8 widget API.

I find that the default widgets have categories list but not author list.

Thanks

Thanks Christian! Fixed.

@Michael: your snippet works as expected.

There's a typo in the code above: inside the My_RSS_Widget class, line 10 inside the widget function - "wp $entry_title" should be "$entry_title".

Anyway, thanks for the great post!

Not tested:

if (version_compare($wp_version, '2.8', '>=')) {
    class My_RSS_Widget extends WP_Widget {
    //code inside the class 
    }
    register_widget('My_RSS_Widget');
}
