#17078 new defect (bug)

is_active_sidebar() doesn't work with Numeric sidebar ID's

This needs a small fix:

Function is_active_sidebar( $index) converts $index to a string

then uses wp_get_sidebars_widgets() to see if the sidebar is active

..but keys in the array wp_get_sidebars_widgets() generates can be integers if the ID's of the registered sidebars are integers

Using an integer breaks dynamic_sidebar() as well, so the sidebar would never be displayed anyway. Also noticed that even using a numeric string breaks a sidebar's widgets from being displayed in the dashboard, but does work with dynamic_sidebar() and related.

Numeric sidebar IDs sound like bad practice too.

Code to reproduce:

add_action( 'wp_head', 'sidebar_dump' );
function sidebar_dump() {
	echo '<pre>';
	var_dump( wp_get_sidebars_widgets() );
	echo '</pre>';

add_action( 'wp_head', 'sidebar_display' );
function sidebar_display() {
	echo '<pre>Sidebar integer: ';
	echo 'Sidebar string: ';
	echo '</pre>';

register_sidebar( array(
    'id'          => 5,
    'name'        => 'Mambo No. 5',
    'description' => 'I break themes',
) );

register_sidebar( array(
    'id'          => '6',
    'name'        => 'Mambo Number 6',
    'description' => 'I break themes',
) );

  • Summary changed from functions not compatible to is_active_sidebar() doesn't work with Numeric sidebar ID's

Just updating the title to something descriptive. I think I've interpreted the issue here correctly..

I think there is a more established ticket somewhere.

WordPress defaults to sidebar-$index when given a numeric sidebar ID. If we were to allow numeric sidebar IDs there's no way to tell if the user is asking for sidebar-$index or index 123 since both could exist. Even if we prioritize sidebar-$index then 123 it wouldn't be clear if/when one loads over the other. I guess my point is that it makes backwards compatibility rough and we likely need to choose one over the other. Since sidebar-$index is the default we should stick with that methodology and alert the user otherwise.

I guess the next question is, should we force register_sidebar() to fail when given a numeric ID accompanied with a __doing_it_wrong() notice or?...
