力用户的语言preference在URL - 重写规则？ [英] force user's language preference in the URL - rewriterule?

问题描述

我要指定用​​户的语言preference在URL中。 是否有可能使用的.htaccess重写规则，如果缺少一个段添加到URL。

URL通常应该有这样的结构

  mysite.com/directory/en
mysite.com/directory/fr
mysite.com/directory/en/about_us.php
mysite.com/directory/fr/about_us.php
 

如果语言不存在，我想自动变换链接直接默认为英语。

  mysite.com/directory
＆GT;＆GT;应转化为mysite.com/directory/en~~V

mysite.com/directory/about_us.php
＆GT;＆GT;应转化为mysite.com/directory/en/about_us.php~~V
 

例如：

  RewriteEngine叙述上

＃不重定向

的RewriteCond％{} REQUEST_FILENAME！-f
的RewriteCond％{} REQUEST_FILENAME！-d
的RewriteCond％{} REQUEST_FILENAME！-l


重写规则^！（FR | EN）/ / ... ...的东西

＃重定向
重写规则^（。+）$的index.php？URL = $ 1 [QSA，L]
 

的**的 * 的**的 一天之后的 的**的 * **的 * 的****

有人可以帮助我了解正是迈克尔的解决方案正在做，以及如何改变htaccess的，如果我移动到新的子目录

  mysite.com/directory
＆GT;＆GT;应转化为mysite.com/directory/en~~V

mysite.com/directory/subdirectory/about_us.php
＆GT;＆GT;应转化为mysite.com/directory/en/subdirectory/about_us.php~~V
 

...

 ＃如果网址不匹配/ XX / otherstuff
！＃^（[AZ] {2}） - 整整两个字母字符不是在字符串的开头
＃$（*） - 存储上述发现为$ 1的结果
的RewriteCond％{REQUEST_URI}！^（[A-Z] {2} /）（。*）$

＃重写到/ EN /
＃^（。+）$  - 开始
＃HTTP：//％{HTTP_HOST} / EN / $ 1  - 取代以http：//主机名/ EN
＃L =最后一站，立即重写过程中，不施加任何更多的规则。
＃R =重定向强制外部重定向，可选择与指定的HTTP状态code
＃QSA  - 查询字符串追加 - 强制重写引擎追加替换字符串的查询字符串部分，以现有的字符串
重写规则^（+）$的http：//％{HTTP_HOST} / EN / $ 1 [L，R，QSA]
 

解决方案

使用的RewriteCond 寻找2信郎code的URI的开始

  RewriteEngine叙述上

的RewriteCond％{} REQUEST_FILENAME！-f
的RewriteCond％{} REQUEST_FILENAME！-d
＃如果网址不匹配/ XX / otherstuff
的RewriteCond％{REQUEST_URI}！^（[A-Z] {2} /）（。*）$
＃重写到/ EN /
重写规则^（+）$的http：//％{HTTP_HOST} / EN / $ 1 [L，R，QSA]
 

如果您使用的是2个以上的字符郎codeS一样，最多4个，使用 [AZ] {2,4} 代替。

I want to specify the user's language preference in the URL. Is it possible to use .htaccess rewrite rule to add a segment to the url, if missing.

URL should normally have this structure

mysite.com/directory/en
mysite.com/directory/fr
mysite.com/directory/en/about_us.php
mysite.com/directory/fr/about_us.php

If language is missing, I want to automatically transform the url to default to english language.

mysite.com/directory                
>> should be transformed to mysite.com/directory/en 

mysite.com/directory/about_us.php   
>> should be transformed to mysite.com/directory/en/about_us.php

Example:

RewriteEngine On 

# don't redirect 

RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l


RewriteRule !^(fr|en)/ /... something...

# redirect 
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

***** one day later **********

can someone help me understand exactly what Michael's solution is doing and how to change htaccess if I move to new subdirectory

mysite.com/directory                
>> should be transformed to mysite.com/directory/en 

mysite.com/directory/subdirectory/about_us.php   
>> should be transformed to mysite.com/directory/en/subdirectory/about_us.php

...

# If the URL doesn't match /xx/otherstuff
# !^([a-z]{2}) - exactly two alpha characters not at the beginning of the string
# (.*)$ - store the result found above as $1
RewriteCond %{REQUEST_URI} !^([a-z]{2}/)(.*)$

# Rewrite to /en/
# ^(.+)$ - begins with 
# http://%{HTTP_HOST}/en/$1 - replace with http://hostname/en
# L = Last Stop the rewriting process immediately and don't apply any more rules.
# R = Redirect Forces an external redirect, optionally with the specified HTTP status    code
# QSA - Query String Append - forces the rewrite engine to append a query string part of the substitution string to the existing string
RewriteRule ^(.+)$ http://%{HTTP_HOST}/en/$1 [L,R,QSA]

解决方案

Use a RewriteCond to look for the 2 letter lang code at the beginning of the URI:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# If the URL doesn't match /xx/otherstuff
RewriteCond %{REQUEST_URI} !^([a-z]{2}/)(.*)$
# Rewrite to /en/
RewriteRule ^(.+)$ http://%{HTTP_HOST}/en/$1 [L,R,QSA]

If you are using more than 2 character lang codes, like up to 4, use [a-z]{2,4} instead.
