I am looking for inserting a function's output before sidebar's first widget, and one in the end after the last widget

Is it possible?

You can create your own actions using do_action, like this:

<?php do_action('before_sidebar'); // you can name it whatever you want ?>
<?php if ( is_active_sidebar('main-sidebar') ) : ?>
        <?php dynamic_sidebar('main-sidebar'); ?>
<?php endif; ?>
<?php do_action('after_sidebar'); ?>

and use add_action() normally:

add_action('before_sidebar', 'before_sidebar_function');
add_action('after_sidebar', 'after_sidebar_function');

UPDATE: depending on the codex you can use wp_meta hook:

Runs when the sidebar.php template file calls the wp_meta function, to allow the plugin to insert content into the sidebar.

but it should be added by theme authors.

k so that means there isn't an already made action for it. i am working on a plugin this might not work as the user wud have to add the sidebar name or add it before sidebar.. etc. – Ayaz Malik Jun 12 '12 at 12:13
If there was sidebar actions they should be on the action reference page on the codex. – Pierre Jun 12 '12 at 14:03
i already went through it, can't find anything like what i need and stated above. i am actually making my 1st plugin.. so new to this. as i see a way around is i would need to register a widget with required function in ti ? and the user wud need to add it from widgets area right ? or is there a way around? – Ayaz Malik Jun 12 '12 at 15:19
yes widgets will do the job, it's not a big deal if the user will have to activate the widget. – Pierre Jun 13 '12 at 6:29

Yes. Put your function, and anything else you want, before and after the dynamic_sidebar function. For example.

<?php if(function_exists ('my_function')) {
} ?>

<p>This is above the first widget.</p>

<?php if ( ! dynamic_sidebar( 'sidebar-1' ) ) : ?>

<?php endif; // end sidebar widget area ?>

<?php if(function_exists ('my_second_function')) {
} ?>

Put the function inside a plugin, or even easier, inside your theme's functions.php file.

There are two options that may not yield the results you are looking for, but it's something.

Hooking a function onto the sidebar?
