title: redirect all product_details.php?id=p_id to mysite/products/product_name
body: <p>i have configured my Wordpress website product detail's permalink to follow <code>&quot;Mysite/products/product_name&quot;</code> url pattern
  but the old pattern <code>&quot;mysite.com/product_details.php?id=1&quot;</code> still working.</p>
