[wp-hackers] Prevent display of dynamic sidebar in widgets.php

Sun May 15 20:51:06 UTC 2011

Ok ive done it. thought i would let you all know the solution i came up
with.

Added a conditional statement to 'admin_menu' action which unregisters the
dynamic sidebar i didnt want to display.

However the problem then is that when ever a widget is added, edited or
removed the ajax that takes care of that resaves all the sidebars and their
consequent widgets. Which means the sidebar that i dont want to display
loses all its settings. which is bad! so... I added a call to the sidebar i
want to hide wrapped in a hidden div. Here is the relevant code-

function add_hidden_sidebar_for_ajax(){
if($_SERVER['PHP_SELF'] == '/wp-admin/widgets.php'){
require_once(ABSPATH . 'wp-admin/includes/widgets.php');
echo "<div id=\"thisOneHere\" style=\"display:none;\">";
wp_list_widget_controls('the-id-of-the-sidebar-i-want-to-hide');
echo "</div>";
unregister_sidebar( 'the-id-of-the-sidebar-i-want-to-hide' );
}
}

add_action( 'admin_menu', 'add_hidden_sidebar_for_ajax' );

My plugin then reregisters the sidebar.

Sorted.

Just thought you may be interested in the solution.
