在colorbox中使用的PHP Cookies

Question

I create a cookie in login.php

setcookie("mes_mod_kull",$userid,time() + 3600,'/');

I have a link for open colorbox like this :

<a href="file_add.php" class="colorbox">Add File</a>

In file_add.php I have to use cookie. I mean, I have to reach to cookie which I was created in login.php

I use this code for test cookie value : print $_COOKIE["mes_mod_kull"]; But there is an error here : Notice: Undefined index: mes_mod_kull in..........

Can someone help me ?

Answer 1

The problem is in setcookie function. It's need to define domain.

I change the following code

setcookie("mes_mod_kull",$userid,time() + 3600,'/');

to

setcookie("mes_mod_kull",$userid,time() + 3600,'/','mydomain.com');

and it's worked. It's little bit ridiculous.

Assuming your print call is in the SAME script as the setcookie, you'll have to wait until the NEXT execution of the script for $_COOKIE to be populated with that new cookie. PHP builds/populates the superglobal (_GET, _POST, _COOKIE, etc...) ONCE while the script is initialization, then does not touch them again for the life of the script. setcookie update $_COOKIE for you.
