Codeigniter - How to get url variable value inside contoller function?

Question

I have URL like this: http://localhost/sitename/some-post-title/code=24639204963309423

Now I have one findUser function in my controller file

Answer 1

If your URI contains more then two segments they will be passed to your function as parameters.

For example, lets say you have a URI like this:

example.com/index.php/products/shoes/sandals/123

Your function will be passed URI segments 3 and 4 ("sandals" and "123"):

If you are using GET to get parameters, you can do like this:

$this->input->get('get_parameter_name'); 

Typically there is a one-to-one relationship between a URL string and its corresponding controller class/method. The segments in a URI normally follow this pattern:

example.com/class/function/id/
