Code:

$data['query'] = $this->registrationmodel->delete_by_pkey($this->uri->segment(3));

I've put uri segment 3. You should put there whatever corresponds to the id of your item.

And the link:

Code:

<a href="&lt;?= site_url ( 'controller/method/' . $id ) ?&gt;">click</a>

[/quote]

i tired that using the anchor() and it sent it to a function in the class with the number that didnt exist so i got a 404 error. is there a difference between using <a > and using the anchor() to make a link?
