WordPress - How to know if a sidebar is empty without loading it?

I'm trying to wrap the sidebar by a DIV, and if the sidebar is empty the DIV should not be displayed

But i cannot use codes like

if(dynamic_sidebar(1))
{
  echo '<div>';
  dynamic_sidebar(1);
  echo '</div>';
}

as it will load the sidebar before the DIV if it is not empty, any ideas?

You can use the WordPress is_dynamic_sidebar(); function.

It returns true if any registered sidebar contains a widget; otherwise false.

Example:

<?php if(is_active_sidebar('my-sidebar') ) { ?>

<div class="about-us">

    <?php dynamic_sidebar('my-sidebar'); ?>

</div>

<?php } ?>

This is the widget-area/sidebar register script I run from the functions.php:

function foxinni_widgets_init() {

    register_sidebar( array(
      'name' => 'My Sidebar',
      'id' => 'my-sidebar',
      'description'   => '','before_widget' => '','after_widget'  => '','before_title'  => '','after_title'   => '',
    ) );

}
add_action( 'widgets_init', 'foxinni_widgets_init' );

Notice that I use the string, my-sidebar, to identify the sidebar by id.

You can always use output buffering. When output buffering is on, anything which would normally be echoed to the screen is instead stored in a buffer. You can then test to see if there is anything in the buffer before outputting your div tags.

ob_start();
dynamic_sidebar(1);
$sidebar = ob_get_clean();  // get the contents of the buffer and turn it off.
if ($sidebar) {
    echo "<div>" . $sidebar . "</div>";
}

Try:

if ( is_active_sidebar(1) )
{
  echo '<div>';
  dynamic_sidebar(1);
  echo '</div>';
}
