Codeigniter no input file specified error

Question

I have installed CI in subdirecotry www.siteb.com/rexona

My .htaccess inside www.siteb.com/rexona :

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /rexona

#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#‘system’ can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn’t true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#This last condition enables access to the images and css folders, and the robots.txt file
#Submitted by Michael Radlmaier (mradlmaier)
RewriteCond $1 !^(index\.php|images|robots\.txt|css)
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>

ErrorDocument 404 /index.php
</IfModule>

In config.php:

$config['index_page'] = '';
$config['base_url'] = '';
$config['uri_protocol'] = 'AUTO';

Whenever I try access controllers I get No input file specified. However it does load default controller, but I cant access any methods in default controller either.

Any thoughts? Thanks.

Answer 1

Your uri_protocol needs to be set to something - at least set it to auto.

The error you are getting is because PHP runs as CGI which means you need to pass the URL rewrite to index.php?/$1 instead (note the question mark).

Answer 2

Godaddy hosting, it seems fixed on.htaccess, myself it is working by changing:

RewriteRule ^(.*)$ index.php/$1 [L]

to

RewriteRule ^(.*)$ index.php?/$1 [QSA,L]

Answer 3

Your $config['uri_protocol'] should not be empty. The default is AUTO, passing in an empty string will break the core URI class, which is used to route your requests through the Router class.

/*
|--------------------------------------------------------------------------
| URI PROTOCOL
|--------------------------------------------------------------------------
|
| This item determines which server global should be used to retrieve the
| URI string.  The default setting of 'AUTO' works for most servers.
| If your links do not seem to work, try one of the other delicious flavors:
|
| 'AUTO'            Default - auto detects
| 'PATH_INFO'       Uses the PATH_INFO
| 'QUERY_STRING'    Uses the QUERY_STRING
| 'REQUEST_URI'     Uses the REQUEST_URI
| 'ORIG_PATH_INFO'  Uses the ORIG_PATH_INFO
|
*/
$config['uri_protocol'] = 'AUTO';

As the comments say: "If your links do not seem to work, try one of the other delicious flavors".
Empty string is not one of those flavors, it would end up trying to read from $_SERVER[''], which is normally going to be empty.
