PHP .htaccess->漂亮的网址(反过来) [英] PHP .htaccess -> pretty url (in reverse)

问题描述

我知道如何重写URL，例如: www.example.com/index.php?id=1&cat=3到www.example.com/1/3/(或其他).我知道.

I know how to make URL's rewrite, for example: www.example.com/index.php?id=1&cat=3 to www.example.com/1/3/ (or whatever). I know that.

我不知道到底是如何更改所有页面中的整个链接以链接到漂亮的URL.我网站上的所有链接都是旧样式(<a href="index.php?id=1&cat=2">)，并且有很多.

What I don't know is how on earth to change my whole links in all pages to link to pretty URL's. All my site's links are old fashion (<a href="index.php?id=1&cat=2">) and there are many.

我要问的是，如果用户单击index.php?id = 1，则有人是否有主意或知道如何自动重定向到该漂亮的url. (如果您在URL中更改标题，则几乎与此站点Stackoverflow一样.)

I`m asking if someone has an idea or know how to automaticaly redirect to that pretty url if the user click on index.php?id=1. (Almost like this site Stackoverflow if you change title in the url).

所以我的推测是...

So my presumtions are...

1. 使用.htaccess读取index.php?id = 1& cat = 2重写本身又重新解释的index/1/3(奇怪)

1. Use .htaccess to read the index.php?id=1&cat=2 to rewrite index/1/3 that itself interprets again (strange)

一个用于执行htaccess改写回原始文件的重定向的php文件...

a php file to do the redirects that htaccess rewrites back to original...

结论:将<a href="index.php?id=1&.....">自动更改为index/1/2

Options +FollowSymLinks
RewriteEngine On
RewriteBase /

# This turns index.php?id=1&cat=2 into index/1/2 and then back 'transparent' into    index.php?id=1&cat=2 if you have old fashioned
# links in your site and don't want to change them :)


# Avoid mod_rewrite infinite loops 
# This is critical if you want to use this code

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule .* - [L]

# Hard-rewrite ("[R]") to "friendly" URL.
# Needs RewriteCond to match original querystring.
# Uses "?" in target to remove original querystring,
#   and "%n" backrefs to move its components.
# Target must be a full path as it's a hard-rewrite.
RewriteCond %{QUERY_STRING} ^id=(\d+)&cat=(\d+)$
RewriteRule ^index.php$ http://localhost/index/%1/%2/? [L,R]

# Soft-rewrite from "friendly" URL to "real" URL.
# Transparent to browser.
# Won't re-trigger the above rewrite, though I'm
#   not really sure why! The order of the rules
#   doesn't seem to make a difference.
RewriteRule ^index/(\d+)/(\d+)/$ index.php?id=$1&cat=$2 [L]

推荐答案

RewriteEngine on

# Prevents browser looping, which does seem
#   to occur in some specific scenarios. Can't
#   explain the mechanics of this problem in
#   detail, but there we go.
RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule .* - [L]

# Hard-rewrite ("[R]") to "friendly" URL.
# Needs RewriteCond to match original querystring.
# Uses "?" in target to remove original querystring,
#   and "%n" backrefs to move its components.
# Target must be a full path as it's a hard-rewrite.
RewriteCond %{QUERY_STRING} ^id=(\d+)&cat=(\d+)$
RewriteRule ^index\.php$ http://example.com/index/%1/%2/? [L,R]

# Soft-rewrite from "friendly" URL to "real" URL.
# Transparent to browser.
RewriteRule ^index/(\d+)/(\d+)/$ /index.php?id=$1&cat=$2

当然，理想情况下，只需修复链接，然后只需要软重写即可. :)

Of course, ideally, you'd just fix your links, and then you'd only require the soft-rewrite. :)

_{经过Apache/2.2.3测试.我想我把硬重写"和软重写"这两个术语组成了.}
