In a lot of my controllers, I use pagination along with the HTML <base> tag’s href attribute for relative link URLs.

Example URL: http://www.domain.com/admin/users/index/pagination_offset

HTML Base tag: <base href=”http://www.domain.com/admin/”>

What this means, is I usually have to build pagination’s base_url option based on where I am and what information is being passed in the URI. A lot of times it ends up looking something like…

$this->load->library('pagination', array(
    'base_url'       => $this->uri->segment(2) . '/' . $this->uri->segment(3) . '/' . $this->uri->segment(4),
    'total_rows'     => $total_rows,
    'per_page'       => 20,
    'uri_segment'    => 4
));

What I decided to do what extend the core CodeIgniter URI class to provide a basic slice method to grab a chunk of the URI by applying PHP’s array_slice function to the segments property of the URI class. Continue reading →
