I need a little help with .htaccess rewrite

Hello, I need a little help with .htaccess file. I have songs, singers and albums links I want to rewrite.

I already rewrote the links and they are like this:

• for the songs is like this: /song/song_name
• for singers: /singer_name
• for albums: /album_name

This is the code in my .htaccess file:

RewriteEngine on
RewriteRule ^singer/([^/\.]+)/?$ /core/controller.php?singer=$1 [L]
RewriteRule ^song/([^/\.]+)/?$ /core/controller.php?song=$1 [L]
RewriteRule ^album/([^/\.]+)/?$ /core/controller.php?album=$1 [L]

I need the links for the songs, singers and albums to be like this:

• for songs /singer_name/song_name
• for singers /singer_name
• for albums /singer_name/album_name

Can anyone help me with this please.

Answer 1

for /singer_name add:

RewriteCond $1 !^(singer|song|album)
RewriteRule ^/?([^/\.]+)/?$ /core/controller.php?singer=$1 [L]

for /singer_name/song_name add:

RewriteCond $1 !^(singer|song|album)
RewriteCond $3 !^(album)
RewriteRule ^/?([^/\.]+)(/([^/\.]+))?.*$ /core/controller.php?singer=$1&song=$3 [L]

for /singer_name/album/album_name add:

RewriteCond $1 !^(singer|song|album)
RewriteCond $3 (album)
RewriteRule ^/?([^/\.]+)(/([^/\.]+))?.*$ /core/controller.php?singer=$1&album=$3 [L]

edit:

Sorry, but rewriting: /singer_name/song_name and /singer_name/album_name can not be done at the same time, as Apache doesn't know the difference between Song name and Album name, unless all song name start with numbers like: 01. Song Name etc.
