do_action("before_sidebar") / do_action("after_sidebar")

   We need to fire some actions before a sidebar is displayed or after a sidebar is displayed.

   It is important for:
   1. Filtering HTML generated by all the widgets in a sidebar.
   2. Outputting custom HTML in the beginning and the end of a sidebar.
   3. Detecting if a specific piece of HTML was generated by a sidebar or not.

   The function dynamic_sidebar() In the file wp-includes/widgets.php should have these lines:
   In the beginning of the function do_action('before_sidebar');
   and in the end of the function do_action('after_sidebar');

   It would really help developers add functionalities to the sidebars.

   Thanks

   @karimzai
   if you look on line 84 of /wp-includes/general-template.php you will see the following code:

   do_action( 'get_sidebar', $name );

   Which will allow you to execute an action at the start of any sidebar included via the get_sidebar() function.

   @mfields

   ya but with do_action( 'get_sidebar', $name ); you never know where the output of a sidebar ends.

   I would like to program this into my theme. However, I'm not really sure how to do it.

   At the end of your sidebar-whatever.php file put do_action('after_sidebar');

   Concept being worked on in multiple places.

   @Ipstenu, this is not a dupe of the idea you linked, it is quite distinct. Before/after action hooks would allow plugin and theme developers to modify the output of widgets, rather than just wrapping them in some pretty. See here for an example, where I was lucky enough to have access to the code calling dynamic_sidebar():

   http://snippets.webaware.com.au/snippets/filtering-the-output-of-wordpress-widgets/

   The action "dynamic_sidebar" is nice, but only tells you when the sidebar starts; you need to know when the sidebar ends too, so that you can capture a sidebar's output using PHP output buffering and then modify it accordingly.

   Ideally, the action hooks would both pass a parameter identifying the sidebar, so that the hooker can apply output buffering and filtering to only the sidebars of interest.

   Incidentally, this has nothing (directly) to do with the "get_sidebar" action Michael Fields is referring to, because the issue is widget zones, not sidebar templates.
