我们可以利用page_template 过滤以实现此目的。我们需要做的就是确保confirmation 是页面标题中的第一个单词
add_filter( \'page_template\', function ( $template )
{
    // Get the current page object
    $post = get_queried_object();
    /**
     * Get the first instance of confirmation, if it is not 0, bail
     * We will be using the page name, which is the slug
     */
    if ( 0 !== stripos( $post->post_name, \'confirmation\' ) )
        return $template;
    // We have confimation as first word, lets continue
    $locate_template = locate_template( \'page-confirmation.php\' );
    // Check if $locate_template is not empty, if so, bail
    if ( !$locate_template )
        return $template;
    // page-confirmation.php exist, return it
    return $locate_template;
});
