Loop through widgets in sidebar
This function from @birgire is almost perfect for me, but how do I call it using the sidebar array as the second parameter, rather than the widget ID. In his example, I would like to do something like this:
wpse_show_widget( 'lobby-sidebar', lobby-sidebar[0] );
In birgire's original post, he gets a Registered Widget called 'sidebar-1' and a registered widget with the ID 'calendar-2'.
Rather than trying to find the specific ID that WordPress assigns to a widget, I'd like the second parameter to be the array ID. That is far easier for me to find than the widget ID.
I modified birgire's function to use wp_get_sidebars_widgets();, but the codex says that's a private function not meant for theme development. I thought someone here might have a more elegant solution.

Reset to default 0I'm using this modification of the original post by birgire, but I don't know if it's "ok" to use wp_get_sidebars_widgets(); in this manner.
function wpse_show_widget_alt( $index, $id ) {
global $wp_registered_widgets, $wp_registered_sidebars;
$did_one = FALSE;
//This built-in func isn't meant for theme or plugin development.
//I don't know any other way to list widgets in an array sorted by sidebar.
$theWidgets = wp_get_sidebars_widgets();
$widgetNumber = $theWidgets[$index][$id];
// Check if $id is a registered widget
if( ! isset( $wp_registered_widgets[$widgetNumber] )
|| ! isset( $wp_registered_widgets[$widgetNumber]['params'][0] ) )
{
return FALSE;
}
// Check if $index is a registered sidebar
$sidebars_widgets = wp_get_sidebars_widgets();
if ( empty( $wp_registered_sidebars[ $index ] )
|| empty( $sidebars_widgets[ $index ] )
|| ! is_array( $sidebars_widgets[ $index ] ) )
{
return FALSE;
}
// Construct $params
$sidebar = $wp_registered_sidebars[$index];
$params = array_merge(
//array( array_merge( $sidebar, array('widget_id' => $id, 'widget_name' => $wp_registered_widgets[$id]['name']) ) ),
array( array_merge( $sidebar, array('widget_id' => $widgetNumber, 'widget_name' => $wp_registered_widgets[$widgetNumber]['name']) ) ),
(array) $wp_registered_widgets[$widgetNumber]['params']
);
// Substitute HTML id and class attributes into before_widget
$classname_ = '';
foreach ( (array) $wp_registered_widgets[$widgetNumber]['classname'] as $cn )
{
if ( is_string($cn) )
$classname_ .= '_' . $cn;
elseif ( is_object($cn) )
$classname_ .= '_' . get_class($cn);
}
$classname_ = ltrim($classname_, '_');
$params[0]['before_widget'] = sprintf($params[0]['before_widget'], $widgetNumber, $classname_);
$params = apply_filters( 'dynamic_sidebar_params', $params );
// Run the callback
$callback = $wp_registered_widgets[$widgetNumber]['callback'];
if ( is_callable( $callback ) )
{
call_user_func_array( $callback, $params );
$did_one = TRUE;
}
return $did_one;}
lobby-sidebar[0]? Because it isn't correct PHP syntax, so it's a little bit hard to guess, what exactly are you trying to achieve... – Krzysiek Dróżdż Commented Nov 28, 2018 at 15:36
