这个the_content 过滤器将用于此。此过滤器允许您更改the_content() 和get_the_content():

add_filter( \'the_content\', \'wpse_members_only\', 20 );
function wpse_members_only( $content ) {
    // If user is not logged in, show restricted content message.
    // Change this conditional statement based on how you want to check for
    // membership status. I\'d suggest using capabilites, e.g. current_user_can( $capability , $object_id );
    if ( ! is_user_logged_in() ) {
        $content = __( \'Sorry, this content is reserved for members only.\', \'text-domain\' );
    }

    return $content;
}
