Question

I have a strange problem. Everything was working fine untill yesterday and suddenly just noticed this problem.

The webiste is here:
http://www.famtripsandinspectionvisits.com/all_trips

If you visit above page and click on “india-kerala” link, it should take you to the following page.

http://www.famtripsandinspectionvisits.com/trips/old_trips/india_kerala

However the browser redirects to this page:
http://www.famtripsandinspectionvisits.com/all_trips/old_trips/india_kerala?/trips/old_trips/india_kerala
This indicates that the following part was added that is extra.
all_trips/old_trips/india_kerala?

I checked my .htaaccess and reset it to defaultbut it still doesn’t affect it. I checked my cofnig.php for base url and everything is same as before. If anyone can help, I will appriciate.

my .htaccess file

# Use PHP5 Single php.ini as default
AddHandler application/x-httpd-php5s .php
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]  

Redirect 301 /invest.php http://www.famtripsandinspectionvisits.com/investment_opportunity
Redirect 301 /buyers.php http://www.famtripsandinspectionvisits.com/buyers

Redirect 301 /register.php http://www.famtripsandinspectionvisits.com/register
Redirect 301 /trips http://www.famtripsandinspectionvisits.com/all_trips

My routes.php

$route['default_controller'] = "site";
$route['404_override'] = '';

$route['fam_admin'] = "fam_admin/login";
/* End of file routes.php */
/* Location: ./application/config/routes.php */

Kind regards

I think what you need to do here is tell mod_rewrite that you want to combine the new and old query strings, which requires the use of the QSA flag:

    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?$1 [QSA,L]

That is my ‘standard’ base set of rules for my Codeigniter projects, the rest I accomplish much as you have with custom routes and the occasional redirect.

Ending the substitution with just a question mark (in the absence of the QSA flag) will erase the existing query string and replace it with the new one, which I think explains what you’re seeing.

The documentation for mod_rewrite gets a bit more in depth when it comes to this:

Modifying the Query String

By default, the query string is passed through unchanged. You can,
however, create URLs in the substitution string containing a query
string part. Simply use a question mark inside the substitution string
to indicate that the following text should be re-injected into the
query string. When you want to erase an existing query string, end the
substitution string with just a question mark. To combine new and old
query strings, use the [QSA] flag.
