redirect old pages by .htaccess

Question

i want to redirect pages from www.sitename.com/sitename/pagename.html and www.sitemap.com/sitename/?page_id=213 to

www.sitename.com/sitename/pagename 

how i can do that by using .haccess file

i tried this code RewriteEngine On RewriteBase / RewriteRule . /digitalways/index.php [L] RedirectMatch 301 (.*).html$ http://www.digitalways.com.sa/digitalways/$1

and i tired also to add

 Redirect 301 / http://digitalways.com.sa/digitalways/

but it is not working but i think both not working because it still gives me an error when i open www.sitename.com/pagename.html

%postname% is not a mod_rewrite rewrite tag. You are going to have to write out the path. mod_rewrite operates before WordPress, or PHP, gets involved. You don't have access to any of that functionality.

If your "contact" page-- the page named "contact"-- has ID 213 you shouldn't have to do anything to redirect, though. This will happen when you enable pretty permalinks.

You can also redirect using WordPress functionality by doing something like:

function redirect_213() {
  if (is_page(213)) {
    wp_safe_redirect(wp_safe_redirect(home_url('/contact')));
  }
}
add_action('template_redirect','redirect_213');

This will probably perform slightly less efficiently than the .htaccess but you may not notice.
