codeIgniter现代重写规则及控制器 [英] CodeIgniter Mod Rewrite Rules and the Controller

问题描述

学习PHP，我用的mod_rewrite和codeIgniter玩耍。我曾与正确的配置我的.htaccess文件

Learning PHP, I am playing around with mod_rewrite and CodeIgniter. I have configured my .htaccess file correctly with

RewriteEngine On
RewriteRule ^(resources)/(.*) $1/$2 [L]
RewriteRule ^(user_guide)/(.*) $1/$2 [L]
RewriteRule (.*) index.php?$1 [L]

我有点明白了正则表达式，并能AP preciate这里发生的事情。重写规则被应用，服务器，而不是处理在上面的个案重视的index.php最终URL（前端控制器）以pretty的URL。到目前为止，一切都很好。

I understand a bit of regex, and can appreciate what happens here. The rewrite rules are applied and the server than handles the final URL which in the above case- attaches index.php (the front controller) to the "pretty" URL. So far so good.

我现在想要一个URL模式：

I now want a URL pattern :

/<person-name>/at/<place>

要获得翻译为：

/index.php/person/list?personName=$1&place=$2

和我处理在人控制我的列表功能的要求。我不明白为什么下不工作：

And i handle the request at my list function in the person controller. I do not understand why the following doesn't work:

RewriteRule ^([a-z]+)/(at)/([a-z]+)$ index.php/person/list?personName=$1&place=$2 [L]

我究竟做错了什么/哪里是我的理解有缺陷？我看到占位符正确提取（$ 1和$ 3），但是，它抛出一个codeIgniter 404。

What am i doing wrong/where is my understanding flawed? I see that the placeholders are extracted correctly ($1 and $3), however, it throws a CodeIgniter 404.

非常感谢！

推荐答案

这可能是最简单的修补程序将解决您的问题。通过包装的括号，你创建另外一个匹配的组，这意味着$ 2将永远是在。这可能是打破一切。你想的index.php人/列表PersonName的= $ 1安培;？地方= $ 3 但是，你可能已经注意到这个问题，并固定它不解决这个问题，在这种情况下，接着往下看。

It's possible that the simplest fix will fix your issue. By wrapping "at" in parentheses, you're creating another matching group, which means that $2 will always be "at." That could be breaking everything. You want index.php?person/list?personName=$1&place=$3 But you may have noticed that issue and fixed it without fixing the problem, in which case, read on.

查看<一个href="http://stackoverflow.com/questions/2894250/how-to-make-$c$cigniter-accept-query-string-urls">How使codeIgniter同意]查询字符串＆QUOT;网址？。这似乎表明，你不能混搭段为基础的方法和查询字符串的方法。没有看到你的控制器code，我不能肯定地说，但我开始调查在那里。您也可以尝试：

Check out How to make CodeIgniter accept "query string" URLs?. It seems to indicate that you can't mix and match the segment-based approach and the query string approach. Without seeing your controller code, I can't say for certain, but I'd start investigating there. You might also try:

RewriteRule ^([a-z]+)/(at)/([a-z]+)$ index.php?person/list/$1/$3 [L]

这将做同样的事情下面的通用CI重定向规则确实;发送网址关到的index.php作为处理查询字符串。你说你得到了它与路线的工作，因此而不是传递查询字符串到控制器，你可以期待的人，地点和两个参数。查询字符串的CI的处理留下了很多不足之处，我从来没有试过mod_rewrite的东西，包括一个查询字符串转换成一个查询字符串。

which would do the same thing the general-purpose CI redirect rule below does; send the URL off to index.php as a query string for processing. You've said you got it working with routes, so rather than passing a query string to your controller, you can expect person and place as two arguments. CI's handling of query strings leaves a lot to be desired, and I've never tried to MOD_REWRITE something including a query string into a query string.
