not able to read cookies

billyemo

Alright...I'm running into all kinds of problems with these cookies...hopefully someone can give me a hand 😉

	  

$tte=time()+6000;
setcookie('amiuname',$uname,$tte);

this is the code for setting my cookie.

echo $_COOKIE['amiuname'];

is the code I'm using to read it. I'm beyond confused because this seems like it should work. They are set by two seperate files...one is login.php (the first) the second is right in my index.php. I was thinking it might be a security thing? I dont know...very confused 😕 Especially because I have checked my cookies and the cookie is set

I really appreciate everyones help

Before you set the cookie, try to print out the $uname variable to check if it is not empty.

billyemo

I know its set because when I chekced the cookie in my cookie manager it was set.

intenz

What you don't realize is this...

if $uname is empty, the cookie will be set as ''
and then when you try to print out your cookie, it shows NOTHING so you think it can't read the cookie.

Trust me, try to print out $uname variable to check the value of that variable.

What do you mean by "set by two seperate files"?

If you set the cookie on one page, you cant use it immediately.
You can only use it on the next page load.

yah, I was unclear on that...what I meant is that I created it in a file that was in one folder and read it in a file thats located in another folder, so I wasnt sure how this would affect the ability to read it.

I'm quite sure uname is set, I will double check it though when I Get home to my code.

The reason I'm about 99% positive is because the value of the cookie (according to my cookie manager in Mozilla) is exactly what I set uname to.

edit:
Now that I'm home and checked it, it did print out uname so I know it's set

intenz

Sigh, $uname can be set though the value of uname is '' (empty).
Learn PHP, before you are "quite sure".

billyemo

as I said in the edit of my above post, I did go ahead and print it out and yes, it was set as I said I was sure it was. I don't know a lot about php, but I do know enough to tell when I set a variable correctly.

Have you tried reloading the page, before reading the cookie?
You can't read a cookie from a page that set the cookie and hasn't been reloaded.

billyemo

yah, thats the first thing I do is click to another page that also is supposed to read the cookie

whats confusing me the most is that a

print_r($_COOKIE);

isnt spitting out ANY cookie information (when now I'm messing with session variables too to see if that works so I have the session Id cookie)

intenz

Try this...

<?PHP
$foo = 'this is a value';
setcookie( 'bar', $foo, time()+3600, '/' );
?>

Then put in another file...

<?PHP
echo $_COOKIE['bar'];
?>

billyemo

okay, I got it fixed, here was the way my code was:

main file:

code
...
...
...
include(uname.php);
...
...
...

okay, uname.php is just a file meant to read the cookie and spit out information. Well, it wasnt reading the cookie at all so I tried just setting it into another variable and reading that in the uname.php file and that still didnt work so I said screw it, put the copied the stuff in the uname file and put it straight into the main file and it works fine.
