I'm new to WordPress. I created my first ugly widget. It located in wp-content/plugins/my-awesome-widget/widget_init.php (no more files in this folder). And it's working. I created a sidebar and registered it in functions.php in my theme folder:
function register_page_widgets() { if (function_exists('register_sidebar')) { register_sidebar( array( 'name' => 'Page sidebar', 'id' => 'page_sidebar', 'description' => '', 'class' => '', 'before_widget' => '<div class="page-sidebar">', 'before_title' => '<div class="title"><span>', 'after_title' => '</span></div>', 'after_widget' => '</div>' ) ); } } add_action( 'widgets_init', 'register_page_widgets' ); All widgets, that located in this sidebar, wrapped in elements, that I defined in array: before_widget, before_title etc. Besides my widget. In my code (in widget_init.php) I wrote:
print_r($args); And I got the result:
Array ( [name] => Page sidebar [id] => page_sidebar [description] => [class] => [before_widget] => [after_widget] => [before_title] => [after_title] => [widget_id] => my_first_widget [widget_name] => My First Widget ) Somehow before_widget, after_widget, before_title and after_title are empty. What's wrong?
My code:

print_r?
