I’m sure this already exists out on the net, but I found a little gem today. When you are working with Codeigniter, you can remove the index.php from your URL’s by creating an .htaccess file with the following information:
RewriteCond $1 !^(index\.php|sitemap\.xml|robots\.txt|user_guide|blog|public|favicon\.ico|LiveSearchSiteAuth\.xml)RewriteRule ^(.*)$ /index.php/$1 [L]
If you notice, I have some other stuff in there to not exclude from passing to index.php like a sitemap.xml, the user_guide directory, the blog directory, a “public” directory (that I use for css/images/js), etc.
You set that in your .htaccess file first, then go into your config.php file and set this:$config['index_page'] = "";
Basically, what that does, is that removes the whole site from processing through index.php in the URL bar (it still goes through there as far as I know, but doesn’t show it), specifically when using Codeigniter built-in functions like redirect().
Figured I’d share that little nugget of knowledge…happy coding!
