Rewriterule for CodeIgniter not working

Question

I have installed a clean Apache2 (plus PHP & MySQL) server and enabled the mod_rewrite in the apache config. I added the .htaccess file to remove the index.php from the url as described in the CodeIgniter wiki.

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

I placed this file in the website's root.

When I try to access the url mydomain.local/index.php/welcome then I get the default page of CodeIgniter. But when I try to access the same page through mydomain.local/welcome then I get the 404 page.

How can I check if the whole rewrite rule is working? And why isn't it working?

Answer 1

Assuming that your configuration (/application/config/config.php) has the index_page disabled:

$config['index_page'] = '';

And your Apache DocumentRoot is: /srv/www/

Create an .htaccess file at the same level as your /application/ directory, with the following content:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

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

You should notice that RewriteBase points to the DocumentRoot (/). If the index.php is in another directory, your should change RewriteBase accordingly.

For a directory structure like:

/srv/www/application/
/srv/www/system/
/srv/www/index.php
/srv/www/.htaccess

Your RewriteBase should be: /

For a directory structure like:

/srv/www/codeigniter/application/
/srv/www/codeigniter/system/
/srv/www/codeigniter/index.php
/srv/www/codeigniter/.htaccess

Your RewriteBase should be: /codeigniter/

And so on, you get the picture.

I found the solution. The htaccess file wasn't allowed to run by the Apache config. So I had to set the AllowOverride flag on the directory to AllowOverride ALL.

Thanks for all the help!

Default .htaccess (from ci userguide http://ellislab.com/codeigniter/user-guide/general/urls.html)

RewriteEngine on 
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

I have confuse above code for a moment, but i have code like this:

RewriteEngine on
RewriteCond $1 !^(index\.php|robots\.txt|.*\.css|.*\.js|.*\.png)
RewriteRule ^(.*)$ ./index.php/$1 [L]

On localhost you must add "./" in front of index.php (3rd line) because in my case, ci directory not placed on root. I think "./" means it should be relative path. For additional condition ".*\.css|.*\.js|.*\.png", it means apache should not rewrite on file with extensions css, js and png.
