如果你是WordPress开发的新手，我建议你使用这个插件https://wordpress.org/plugins/members/, 有一个选项允许您根据用户角色禁用内容，您还可以使用插件轻松创建角色。

至于你的问题：如果你不想让拥有订阅者角色的用户查看内容，我正在使用twentysixteen 以主题为例

// Start the loop.

if( have_post() ) :
    while ( have_posts() ) : the_post();

        /*
         * Include the Post-Format-specific template for the content.
         * If you want to override this in a child theme, then include a file
         * called content-___.php (where ___ is the Post Format name) and that will be used instead.
         */
        if( current_user_can( \'edit_posts\' ) ) :
            // can accessed by contributor and the others but not subscriber
            get_template_part( \'template-parts/content\', get_post_format() );

        endif;



    // End the loop.
    endwhile;
endif;
