PHP Cookies Wen Post to New Form

HI. I have the following code in each of to forms, one of which posts to the other:

<?php
if(!isset($_COOKIE['ej_saveabuck_CartID'])) {
 $CartID = md5(uniqid(rand()));
  setcookie("ej_saveabuck_CartID", $CartID, time() + 31536000);
} else {
   $CartID = $_COOKIE['ej_saveabuck_CartID'];
}
?>

When I stick to the first page, doing posts to itself to calculate totals and such, it's fine. But when I post to the second page, it has a whole different cookie value which has nothing in the database.

Help!!!!

You could instead use sessions to store the ID, although if its a cookie issue we might come back to the same problem

session_start(); //this must be at top of script

if (!isset($_SESSION['cartID'])) {
 $CartID = md5(uniqid(rand()));
 $_SESSION['cartID'] = $CartID;
} else {
   $CartID = $_SESSION['cartID'];
}

Access the ID using $_SESSION['cartID']

Code looks ok, so browser may be rejecting cookies, check your security settings in your browser.

also, add this code for debugging to check whether it is set or not on the next page.

echo (isset($_COOKIE['ej_saveabuck_CartID'])) ? "cookie is set" : "cookie is NOT set";

Just tested to double check and the code is fine

if(!isset($_COOKIE['ej_saveabuck_CartID'])) {
 $CartID = md5(uniqid(rand()));
  setcookie("ej_saveabuck_CartID", $CartID, time() + 31536000);
} else {
   $CartID = $_COOKIE['ej_saveabuck_CartID'];
}

outputting the contents with:

echo $_COOKIE['ej_saveabuck_CartID'];

returns the same cookie value for both pages.


You do have that full code on both pages right? otherwise you might be accidently overwriting the value is the isset check is not present second time around.

Yes, the exact same code.

did you check your browser security level?

if it it set to a higher level it may be blocking your cookie so on the second form when the conditional statement is parsed it will regard the cookie as not having been set and so will generate a new cart id and will try to set a new cookie.

If your error reporting level has been turned down you can also add the following to the top of your script for debugging purposes so you can see any problematic errors:

error_reporting(E_ALL ^ E_NOTICE);

Is the second page in the same directory and path as the the first page,

for example

http://test.com/program.php  posts to itself then you try to get the cookie at http://www.test.com/program.php

this may not work properly since the cookie was originally set under http://test.com/program.php (no www)
