No input file specified

Question

I'm running Anchor CMS and I just upgraded to version 0.8. When I try and run the installer I get a 'No input file specified' error. I believe it's more than likely a .htaccess problem but I'm not sure what the correct settings should be. My site can be found here. My .htaccess is set to: ``` RewriteEngine On RewriteBase {base} # Allow any files or directories that exist to be displayed directly RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d # Rewrite all other URLs to index.php/URL RewriteRule ^(.*)$ {index} [L] ErrorDocument 404 index.php ``` I'm also using a GoDaddy as the hosting provider if that helps.

Accepted Answer

The No input file specified is a message you are presented with because of the implementation of PHP on your server, which in this case indicates a CGI implementation (can be verified with `phpinfo()`).

Now, to properly explain this, you need to have some basic understanding on how your system works with URL's. Based on your .htaccess file, it seems that your CMS expects the URL to passed along as a `PATH_INFO` variable. CGI and FastCGI implementations do not have `PATH_INFO` available, so when trying to pass the URI along, PHP fails with that message.

We need to find an alternative.

One option is to try and fix this. Looking into the documentation for core php.ini directives you can see that you can change the workings for your implementation. Although, GoDaddy probably won't allow you to change PHP settings on a shared enviroment.

We need to find an alternative to modifying PHP settings Looking into `system/uri.php` on line 40, you will see that the CMS attempts two types of URI detection - the first being `PATH_INFO`, which we just learned won't work - the other being the `REQUEST_URI`.

This should basically, be enough - but the parsing of the URI passed, will cause you more trouble, as the URI, which you could pass to `REQUEST_URI` variable, forces `parse_url()` to only return the URL path - which basically puts you back to zero.

Now, there's actually only one possibilty left - and that's changing the core of the CMS. The URI detection part is insufficient.

Add `QUERY_STRING` to the array on line 40 as the first element in `system/uri.php` and change your .htaccess to look like this:

```
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d

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

This will pass the URI you request to `index.php` as `QUERY_STRING` and have the URI detection to find it.

This, on the other hand, makes it impossible to update the CMS without changing core files till this have been fixed. That sucks...
