Simple Search: Passing Form Variable to URI Using CodeIgniter

Question

I have a search form on each of my pages. If I use form helper, it defaults to $_POST. I\'d like the search term to show up in the URI:

http://examp

Check out this post on how to enable GET query strings together with segmented urls.

After enabling that you can use the following method to retrieve the additional variables.

// url = http://example.com/search/?q=text
$this->input->get('q');

This is better because you don't need to change the permitted_uri_chars config setting. You may get "The URI you submitted has disallowed characters" error if you simply put anything the user enters in the URI.
