这是可能的，将此代码放入主题的functions.php 文件：

add_action( \'init\', \'wpse_244614_no_dashboard_for_subscriber\' );
function wpse_244614_no_dashboard_for_subscriber() {

    $to = \'https://google.com/\';

    $is_subscriber = current_user_can( \'subscriber\' );
    $in_backend    = is_admin();
    $doing_ajax    = defined( \'DOING_AJAX\' ) && DOING_AJAX;

    if ( $is_subscriber && $in_backend && ! $doing_ajax ) {
        wp_redirect( $to );
        exit;
    }
}
