将单个和连续的下划线重写为破折号

Question

我正在尝试将带有下划线的 URL 重写为购物网站的破折号。

产品名称当前使用下划线表示空格。一个典型的 URL 如下：

http://test.local/category-name/product_name_a

我目前的.htaccess如下，成功改写为：

http://test.local/category-name/product-name-a

RewriteEngine On
RewriteBase /

#Rewrite Underscores to dashes
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^_]*)_([^_]*)$ $1-$2 [L,R=302,NE]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^_]*)_+(.+)$ $1-$2 [L]

# Redirect to index.php & standard Opencart stuff
RewriteRule ^sitemap.xml$ index.php?route=feed/google_sitemap [L]
RewriteRule ^googlebase.xml$ index.php?route=feed/google_base [L]
RewriteRule ^download/(.*) /index.php?route=error/not_found [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css)
RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]

但是有些产品中有连续的下划线，例如

http://test.local/category-name/product__name__b

或两者的混合，例如：

http://test.local/category-name/product__name_a

我已经尝试将这些重写为：

http://test.local/category-name/product--name--b

http://test.local/category-name/product--name-a

不破坏现有的重写。非常感谢任何帮助。

只需在第二条规则中调整您的正则表达式：

RewriteEngine On
RewriteBase /

#Rewrite Underscores to dashes
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^_]*)_([^_]*)$ $1-$2 [L,R=302,NE]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^_]*)_(.+)$ $1-$2 [L]

# Redirect to index.php & standard Opencart stuff
RewriteRule ^sitemap\.xml$ index.php?route=feed/google_sitemap [L]

RewriteRule ^googlebase\.xml$ index.php?route=feed/google_base [L]

RewriteRule ^download/(.*) /index.php?route=error/not_found [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css)
RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]
