Struggling to rewrite the URL using htaccess - .htaccess

Question

I'm totally newbie in htaccess and it has been a month since I'm trying to rewrite this one URL but no luck. Tried searching on the internet a lot and tried out the method that worked for others but not working for me unfortunately.
The htaccess rule for my dynamic page works, for example site/index.php?viewpage=application shows up as site/application
What I'm struggling to do is, I'm trying to rewrite the following url: site/application?name=abcd&date1-2-3&version=5.0 to site/application/abcd/1-2-3/5.0
This is my htaccess code
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php?viewpage=$1 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/([^/]*)/([^/]*)$ /application?name=$1&date=$2&version=$3 [L]

Answer 1

Try this :
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{QUERY_STRING} !name
RewriteRule ^([^/]+)$ index.php?viewpage=$1 [L]
RewriteRule ^(.+)/(.+)/(.+)/(.+)$ /$1?name=$2&date$3&version=$4 [L]
If you want the last line to be limited with application only , replace with this :
RewriteRule ^application/(.+)/(.+)/(.+)$ /application?name=$1&date$2&version=$3 [L]
UPDATE CODE:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{QUERY_STRING} !name
RewriteRule ^([^/]+)$ index.php?viewpage=$1 [L]
RewriteRule ^(.+)/(.+)/(.+)/(.+)$ index.php?viewpage=$1?name=$2&date$3&version=$4 [L,NE]
