apache rewrite url for codeigniter

Question

I need to build app and i'm using codeigniter for this. Company sends me a link in format that cant be changed from their side Link is like:

someurl.com/sms.php?phone=12345678&msg=msg15&code=777&country=cc&oper=someoper& mssid=1234567892&notcharged=0&date=2011-12-26+23%3A31%3A27&keyword=msg&created=2011-12-26+23%3A31%3A26

How can i rewrite it with .htaccess so the codeigniter gets link in segmented format like

someurl.com/sms/myfunction/12345678/msg15/777/cc/someoper/1234567892/0/2011-12-26+23%3A31%3A27/msg/2011-12-26+23%3A31%3A26

Thanks

Edit. Spent some hours and tried something like this:

RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} ^phone\=([^&]+)\&msg\=([^&]+)\&code\=([^&]+)\&country\=([^&]+)\&oper\=([^&]+)\&mssid\=([^&]+)\&date\=([^&]+)\&keyword\=([^&]+)$
RewriteRule ^test\.php$ /sms/doParse/%1/%2/%3/%4/%5/%6/%7/%8 [R,L]

And then typing url like this:

http://test.airtel.lv/test.php?phone=12345678&msg=msg15&code=777&country=cc&oper=someoper&mssid=1234567892&date=2011-12-26+23%3A31%3A27&keyword=msg

I got this:

http://test.airtel.lv/sms/doParse/12345678/msg15/777/cc/someoper/1234567892/2011-12-26+23%253A31%253A27/msg?phone=12345678&msg=msg15&code=777&country=cc&oper=someoper&mssid=1234567892&date=2011-12-26+23%253A31%253A27&keyword=msg

Why returned url has GET params in the ending ? And one more question, if that company will change and add extra param to link, the rewriting will be broken ? Then how can it be more universal ?

Answer 1

Try this placing this in your .htaccess file in an appropriate place in your document root:

RewriteEngine on

RewriteRule ^sms.php$ /sms/myfunction/ [L]

RewriteCond %{QUERY_STRING} ^[^=]+=([^&]+)&?(.*)
RewriteRule ^sms/myfunction/(.*)$ /sms/myfunction/$1/%1?%2 [L]

The first RewriteRule changes the /sms.php part of the URI to /sms/myfunction/ and the second rule will append each value in your query string into its own part of the path. So a url like this: http://someurl/sms.php?a=1&b=2&c=3&d=4&e=5&f=6&g=7&h=8&i=9 will have the URI internally rewritten to /sms/myfunction/1/2/3/4/5/6/7/8/9. There's no checks on what the variable names are in the query string, only the value is extracted and appended to the URI path.

If you put that code in your server or vhost config (instead of an htaccess file) add a / in front of the sms in each of the rules so it says ^/sms because rules in the htaccess have the leading slash stripped off when matching against the URI.

Answer 2

just handle the GETs in your controller. it's okay, GET isnt evil.

parse_str($_SERVER['QUERY_STRING'], $_GET);

then you can have a simpler rewrite to handle the special route
