php - htaccess redirect virtual directory -

can't figure out i'm doing wrong.

rewriteengine on  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewritecond %{request_filename} !-l  rewriterule ^(.+)\.php$ detail.php?name=$1 [nc,qsa,l] rewriterule ^(.+)/directory/\.php$ detail2.php?name=$1 [nc,qsa,l] 

the first rewriterule should redirect (ending on php domain.com/product1.php) root domain detail.php (it can not affect things domain.com/contact.php)

a 2nd rewriterule should redirect domain.com/directory/product-b1.php detail2.php

rewriteengine on rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d  rewriterule .* /foldernamehere/index.php/$0 [pt,l]  

paste code in .htaccess file resolve problem
