.htacces重寫規則問題

Question

這是工作：

RewriteRule ^([a-z]{2}/){0,1}showCategory/([0-9]*)/([0-9]*)(/{0,1})$    /main.php?id=$2&il[lang]=$1&page=$3 [L] 

這個網址：

http://localhost/showCategory/590/10 

現在，我想這也工作：

http://localhost/showCategory/590/transport/10 

我嘗試的規則：

RewriteRule ^([a-z]{2}/){0,1}showCategory/([0-9]*)/([a-z\-_0-9\+]*)/([0-9]*)(/{0,1})$    /main.php?id=$2&il[lang]=$1&page=$3 [L] 

如何更改RewriteRule？

Answer 1

這一個工程有兩個URL

RewriteRule ^([a-z]{2}/)?showCategory/([0-9]+)(?:/[A-Za-z0-9_-]+)?/?([0-9]+)/?$ /main.php?id=$2&il[lang]=$1&page=$3 [L] 

我也是{0,1}與簡化？這也是一樣的。

的關鍵是(?:/[A-Za-z0-9_-]+)?，解釋：

(?:     Non-capturing group, so what's in here will not be put in any $n 
/     Match the slash 
    [A-Za-z0-9_-]+  Match any word with letters/numbers/dashes/underscores 
)?     Close non-capturing group, and the ? means it's optional 

Answer 2

試試這個規則：

RewriteRule ^([a-z]{2}/)?showCategory/([0-9]+)/[a-z-_0-9+]+/([0-9]+)/?$ /main.php?id=$2&il[lang]=$1&page=$3 [L]
