.htaccess的URL重写的问题：如何区分上市和详细页 [英] Htaccess Rewriting URL issue: how to distinguish Listing and detail page
问题描述
我正在开发一个电子商务网站，用户可以在任何类别发布项目（类别可用2〜4级）。
I am developing an commerce site, Where users can post items in any categories (categories can be 2 to 4 levels).
我要生成上市和详细信息页面网址：
I want to generate URL for listing and details pages:
- 清单页面将显示在内部类的产品清单
- 详细页面将显示在内部类别中的所有信息项
（内蒙古类是指分层，即最后一类在/分类/ autos4x4s /三菱/职业者/内平均枪骑兵）
- Listing page will show list of items in inner category
- Detail Page will show all information for item in inner category
(Inner category means Last Category in hierarchic i.e. in
/classified/autos4x4s/mitsubishi/lancer/inner mean "lancer")
下面是链接我要生成
-
/分类/ autos4x4s /三菱/职业者/（上市为）
<$c$c>/classified/autos4x4s/mitsubishi/lancer/2011/3/12/lancer-2002-in-good-condition-14/ （查看详细）
我想重定向如果URL，如果6项被传递（4类别名称+ 2日期和名称），以detail.php存在只有4类别ads.php。
I want to redirect to ads.php if just 4 categories exist in URL and to detail.php if 6 items are passed (4 category name + 2 date and title).
我写这些规则：
#listing ads
RewriteRule ^(.*)/(.*)/(.*)/(.*)/?$ ads.php?c1=$1&c2=$2&c3=$3&c4=$4 [NC,L]
#Detail pages
RewriteRule ^(.*)/(.*)/(.*)/(.*)/(.*)/(.*)/?$ detail.php?c1=$1&c2=$2&c3=$3&c4=$4&dt=$5&at=$6 [NC,L]
但是，所有的网站页面重定向到ads.php（列表页）甚至主页。
But all the sites page redirect to ads.php (Listing page) even home page.
我改变了规则如下：（虽然我不想使用清单和详细的网址为什么我在一些网站上看到，因为我想开始： <$c$c>/classified/autos4x4s/mitsubishi/lancer/2011/3/12/lancer-2002-in-good-condition-14/)
I changes the rules as follow: (Even though I do not want to Use Listing and Detail in start of URL. Why as I see on some site as I want: /classified/autos4x4s/mitsubishi/lancer/2011/3/12/lancer-2002-in-good-condition-14/)
#Listing pages
RewriteRule ^Listing/(.*)/(.*)/(.*)/(.*)/?$ ads.php?c1=$1&c2=$2&c3=$3&c4=$4 [NC,L]
#Detail pages
RewriteRule ^Detail/(.*)/(.*)/(.*)/(.*)/(.*)/(.*)/?$ detail.php?c1=$1&c2=$2&c3=$3&c4=$4&dt=$5&at=$6 [NC,L]
现在所有其它页面都很好，但是当我通过 /分类/ autos4x4s /三菱/撰稿人/ 2011/3/12 /蓝瑟-2002-在良好的条件-14 / 它总是转到页列表（ads.php）不详细页面。
Now all other pages are fine, but when I pass /classified/autos4x4s/mitsubishi/lancer/2011/3/12/lancer-2002-in-good-condition-14/ it always goes to Listing page (ads.php) not to detail page.
任何帮助将是AP preciated。
Any help would be appreciated.
推荐答案
请用正则表达式的部分注意：
Please watch out with the regex part:
(.*)/(.*)/(.*)/(.*)/(.*)/(.*)
该点会匹配'/'太多，因此对于某些URL这将导致可能匹配的combinatoric爆炸，使得它非常低效重写。请考虑写这部分就像任何一种：
The dot will match a '/' too, so for certain urls this leads to a combinatoric explosion of possible matches, making it very inefficient to rewrite. Please consider writing this part like any of these:
(\w+)/(\w+)/(\w+*)/(\w+*)/(\w+*)/(\w+*)
([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)
您的问题是与此相关的还有：含有6/字符的URL会被你的4倍匹配斜线图案太（因为匹配/和）
Your question is related to this as well: a url containing 6 '/' characters will be matched by your 4 times slash pattern too (because . matches / as well)
您可以尝试：
#Listing pages
#e.g. /classified/autos4x4s/mitsubishi/lancer/
RewriteRule ^(\w+)/(\w+)/(\w+)/(\w+)/$ ads.php?c1=$1&c2=$2&c3=$3&c4=$4 [NC,L]
#Detail pages
#e.g. /classified/autos4x4s/mitsubishi/lancer/2011/3/12/lancer-2002-in-good-condition-14/
RewriteRule ^(\w+)/(\w+)/(\w+)/(\w+)/(\d+/\d+/\d+)/([^/]+)/$ detail.php?c1=$1&c2=$2&c3=$3&c4=$4&dt=$5&at=$6 [NC,L]
