CodeIgniter Mod重写规则和控制器

Question

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]

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.

I now want a URL pattern :

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

to get translated to :

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

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]

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.

Many thanks!

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.

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]

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.
