Question

I have a button on my site. When a user clicks on it
it sets a cookie like this:

setcookie("check",$id, mktime (0, 0, 0, 12, 31, 2015));

But when the user goes to other pages and clicks on the button again the cookie for old page is getting replaced by the new page.

How can I set a unique cookie for each page?
I am using PHP.
I tried:

setcookie("$id",$id, mktime (0, 0, 0, 12, 31, 2015));

but it didn’t work.
How can I give it a unique name each time?

Answer 1

Use the 4th parameter, path.

setcookie("check",$id, mktime (0, 0, 0, 12, 31, 2015), "/mypath/mypage.php"); 

See this reference: http://php.net/manual/en/function.setcookie.php

You should also consider setting the 5th parameter, domain:

setcookie("check",$id, mktime (0, 0, 0, 12, 31, 2015), "/mypath/mypage.php", ".mysite.com");
