Mod Rewrite Help

[jgd12345]

Hi, i'm useless at regular expressions and having trouble implement mod_rewrite to make my site search engine friendly. The url I want to rewrite is:

 

/products/index.php?category_id=$cid(&page=$page)?

 

to:

 

/products/[a-zA-Z0-9-/]*/([0-9]+)$/? (something like this - i've read alot of tutorials but can't get my head around it)

 

eg

 

/products/cat-1/subcat-1/subcat-2/12/ or

/products/cat-1/subcat-1/subcat-2/12 (with or without the ending slash) or

/products/cat-1/subcat-1/subcat-2/12/1 (including the page number - again with or without the ending slash)

 

note: the 12 is the category_id and the 1 is the page

 

and:

 

/products/product.php?product_id=$pid

 

to:

 

/products/cat-1/subcat-1/subcat-2/product-name/19 (again with or without the ending slash)

 

note: the 19 is the product_id.

 

Would appreciate it if someone could help. Thanks
