wp_admin_bar_wp_menu()
云策文档标注
概述
wp_admin_bar_wp_menu() 函数用于向 WordPress 管理工具栏添加 WordPress 徽标菜单,包含关于 WordPress、参与贡献等子菜单项。该函数根据用户权限和站点类型动态生成菜单链接。
关键要点
- 函数接受一个必需的 WP_Admin_Bar 实例参数,用于操作管理工具栏。
- 根据 current_user_can('read') 和 is_multisite() 条件,动态设置 about_url 和 contribute_url。
- 使用 WP_Admin_Bar::add_node() 添加主菜单节点和多个子菜单节点,如关于、参与、WordPress.org、文档等。
- 当 about_url 不可用时,设置 tabindex="0" 以确保子菜单可访问。
- 函数内部调用了多个 WordPress 核心函数,如 self_admin_url()、get_dashboard_url() 和 __() 进行本地化。
代码示例
function wp_admin_bar_wp_menu( $wp_admin_bar ) {
if ( current_user_can( 'read' ) ) {
$about_url = self_admin_url( 'about.php' );
$contribute_url = self_admin_url( 'contribute.php' );
} elseif ( is_multisite() ) {
$about_url = get_dashboard_url( get_current_user_id(), 'about.php' );
$contribute_url = get_dashboard_url( get_current_user_id(), 'contribute.php' );
} else {
$about_url = false;
$contribute_url = false;
}
$wp_logo_menu_args = array(
'id' => 'wp-logo',
'title' => '' .
/* translators: Hidden accessibility text. */
__( 'About WordPress' ) .
'',
'href' => $about_url,
'meta' => array(
'menu_title' => __( 'About WordPress' ),
),
);
if ( ! $about_url ) {
$wp_logo_menu_args['meta'] = array(
'tabindex' => 0,
