Cookie in PHP 5.2

rajug

I have set one cookie in page1.php as :

setcookie("mycookie","MyCookieValue",time()+3600*24);

Then when i try to access the above set cookie in page2.php as :

echo $_COOKIE['mycookie'];
//or
print_r($_COOKIE);

It works fine because i came to page2.php by clicking on the link in the page2.php. Then after i have a form in page2.php and i submit that form to page3.php and try to access (use) cookie in the same way in page2.php, i could not found the value. Where did i loose the value?

Please help on it.

With Regards

Are you still on the same domain and subdomain the entire time? Using your code, if I went to http://yoursite.com/page1.php and the cookie was set, a script located at http://www.yoursite.com/page3.php would not be able to read the cookie. The same would be true if the situation was reversed.

Don't believe me? Log in to PHPBuilder, and then take the "www." out of the address (or add it, if it's not there) - you'll be logged out. Why? Because the cookie wasn't set - different subdomain

You can solve this by specifying the domain of your site as ".yoursite.com" . The preceding period basicaly means any subdomain.

Thank you for the reply. I am aware of that case what you have mentioned in the post.

Actually i am working on the web tracking site. So, I have used JavaScript code to be installed in the tracking pages. When the page of tracking domain is loaded the JavaScript will call my server's php page and that php page will set the cookie as the visitor id. Then when the vistor goes to the next page, then next page will also call my server's same php script. It checks the cookie whether it is set already or not. Till now it is working properly.

But in some pages of tracking web pages, i have to post some data to my server's same php script page. So i have used curl to post the data. At that time too i want to check whether the cookie has already been set or not. But i could not get the value of the cookie that is already set when the previous page was loaded.

Where I am missing what and what should i do for this. Or this is impossible at all.

Please help me.

Thanx in advance.
