自定义主题初始小工具(widge)等方法:add_theme_support()

How to use it

Themes define a subset of core-provided starter content using add_theme_support() – let’s look at a breakdown of how Twenty Seventeen does things. In its setup function hooked to after_setup_theme, we see an array with collections of widgets, posts (pages), attachments, options, theme mods, and nav menus registered as the starter content. The customizer looks for this starter-content at after_setup_theme priority 100, so do make this call at that point or later:

add_theme_support( 'starter-content', array( /*...*/ ) )

Widgets

Each widget area ID corresponds to one sidebar registered by the theme, with the contents of each widget area array being a list of widget “symbols” that reference core-registered widget configurations. Most default widgets are available (archivescalendarcategoriesmetarecent-commentsrecent-posts, and search), as well as text widgets with business hours (text_business_info) and a short prompt for an “about this site” style blurb (text_about). Themes should place widgets based on what works best in that area – for instance, business info in a footer widget of a business-centric theme, or a nicely styled calendar widget in the sidebar of a blog.

Custom widgets can also be registered at the time of starter content registration or later filtered in, which will be more likely the case for plugins, as add_theme_support() for starter content will be overridden by any later calls.

// Custom registration example
add_theme_support( 'starter-content', array(
    'widgets' => array(
        'sidebar-1' => array(
            'meta_custom' => array( 'meta', array(
                'title' => 'Pre-hydrated meta widget.',
            ) ),
        ),
    ),
);
// Plugin widget added using filters
function myprefix_starter_content_add_widget( $content, $config ) {
    if ( isset( $content['widgets']['sidebar-1'] ) ) {
        $content['widgets']['sidebar-1']['a_custom_widget'] = array(
            'my_custom_widget', array(
                'title' => 'A Special Plugin Widget',
            ),
        );
    }
    return $content;
}
add_filter( 'get_theme_starter_content', 'myprefix_starter_content_add_widget', 10, 2 );
