Hi,
for the widget itself there isn’t, but you can make a copy of the widget by extending the widget class like this
add_action( 'widgets_init', 'my_widgets_init', 100 );
function my_widgets_init() {
class My_Recent_Ads_Widget extends Adverts_Widget_Ads {
public function widget($args, $instance) {
// your custom HTML here
return parent::widget($args, $instance);
}
}
unregister_widget( "Adverts_Widget_Ads" );
register_widget( "My_Recent_Ads_Widget" );
}
Now you will just need to modify the content function widget() returns to display your own version of the template.
