使用CodeIgniter获取URL段并将其存储到Cookie中

Question

For a kind of conversion tracking, I want to store a part of the URL into a cookie and use this into my model functions.

So I think about https//:www.example.com?track=this

How I can get the part of the track (=this) with CodeIgniter and save it into a cookie?

To create a cookie I think that's the way,

$this->load->helper('cookie');
                $cookie = array(
                        'name'   => 'track',
                        'value'  => '???',                            
                        'expire' => '300',                                                                                   
                        'secure' => TRUE
                        );
               set_cookie($cookie);  

How I can get the part of URL and set cookie etc with CodeIgniter on every possible page? So I mean, no matter over which page the user call the website, I need to make sure that this tracking info is stored in every case.

Go get the cookie later, I think I can use $cookie= get_cookie('track');

Thanks for showing me the way to do it with CodeIgniter.

Answer 1

Mainly you need to use parse_url to extract url to query string and then parse_str to extract query string .

First, you need to get query string from you URL

$query = parse_url('https//:www.example.com?track=this&h=1');
echo'<pre>';print_r($query);

Output:

Array
(
    [path] => https//:www.example.com
    [query] => track=this&h=1
)

Then you need to extract query

parse_str($query['query'],$array);
echo'<pre>';print_r($array);die;

Output:

Array
(
    [track] => this
    [h] => 1
)

From here you can store your above array information in cookies

Answer 2

to get the wanted part of the query-string there is a built-in function of Codeigniter

$myval=$this->input->get('track', TRUE);

I've add this with a part to store and get the cookie in the header of my mainlayout-theme.

So it will works :-)
