Dynamically Dynamic Sidebar

This plugin enables you to create unlimited custom sidebar/widget areas and switch existing areas. You can do this without touching your theme.

This plugin utilizes term meta api and so it works only with WordPress 4.4 and above.

Your theme needs to use is_active_sidebar() when calling dynamic_sidebar() function.

This will work.

if ( is_active_sidebar( 'sidebar-1' ) ) {
    dynamic_sidebar( 'sidebar-1' );
}

This doesn’t work.

dynamic_sidebar( 'sidebar-1' );

If you only want to output your custom sidebar, put this code on where you want to display the sidebar in your theme.

do_action( 'dynamically_dynamic_sidebar' );

ウィジェットエリアをいくつでも定義し、カテゴリやタグ、カスタム分類ごとに差し替えたり、投稿・ページ・カスタム投稿から使いたいサイドバーを指定したりすることができます。「スクリーンショット」のタブをごらんいただくと、イメージが湧きやすいと思います。

How many widget areas can I create?

Unlimited.

How do I switch existing sidebar or widget area?

Choose the target widget area in admin panel. The admin page for this plugin is located at Admin > Appearance > Dynamically Dynamic Sidebar.

You need to make sure that the call of dynamic_sidebar is properly wrapped with is_active_sidebar() conditional tag.

if ( is_active_sidebar( 'sidebar-1' ) ) {
    dynamic_sidebar( 'sidebar-1' );
}

Or you can just output your dynamically created sidebar with do_action( 'dynamically_dynamic_sidebar' );, too.
