Do I need to extend the session class? (Last visited url) - El Forum - 03-25-2010
[eluser]tomdelonge[/eluser]
So I made a little function so that when something is done, I can redirect the user to the last page. For example, maybe they added an item to their cart, I could give them a link that says, "back to search results" or "back to example product". I have a shopping library I'm making that just takes care of simple functions like add_to_cart and stuff. The library is autoloaded, and In the construct I run _history(). It seems to work fine.
If I wanted to extend the session class, how would I do so? I know how to make MY_Session extends CI_Session or whatever, but how do I make it so this function runs everytime the session class does? (In other words, can I "extend" a function?)
Do you recommend that? Or should I just leave it as is (It works).
Code:
function _history()
{
$current = $this->session->userdata('current');
if( ! $current)
{
$current = current_url();
}
$this->session->set_userdata('before', $current);
$this->session->set_userdata('current', current_url());
}Thanks.

Why would you want to extend the session class? What benefit do you see from doing that?

I just figured it's useful and has to do with the user's session. I'd be able to use it in future projects more easily if I just extended the class.
Should I just not worry about it? And copy and paste (or rewrite, since it's simple enough) into each project?
I can do that I guess. Just wondered how I could extend the construct of the session class.

tomdelonge,
Make it by using hooks.
Let me explain better:
file: ../application/hooks/url_register.php
Code:
Class UrlRegister {
function history()
{
$current = $this->session->userdata('current');
if( ! $current)
{
$current = current_url();
}
$this->session->set_userdata('before', $current);
$this->session->set_userdata('current', current_url());
}
}file: application/config/hooks.php
Code:
$hook['post_controller'][] = array(
'class' => 'UrlRegister',
'function' => 'history',
'filename' => 'url_register.php',
'filepath' => 'hooks',
'params' => null
);
