Having trouble reading cookie values

speedphreak

I've got three scripts that I wrote to see if I was setting cookies properly. Here they are.

<?
//setcookie.php sets a cookie with two values (user_id and user_name)

setcookie('mycookie[user_id]', '1', '60', '/');
setcookie('mycookie[user_name]', 'joe smith', '60', '/');

echo "<a href='showcookie.php'>show cookie values</a>";
?>

<?
//showcookie.php checks to see if the cookies are set, and shows the values

if (isset($HTTP_COOKIE_VARS['mycookie[user_id]']))
	{
	     echo $HTTP_COOKIE_VARS['mycookie[user_id]'];
	     echo $HTTP_COOKIE_VARS['mycookie[user_name]'];
	}
else
	{
	     echo "no cookie set";
	}

echo "<br><a href='setcookie.php'>set a cookie</a><br>";
echo "<a href='removecookie.php'>remove a cookie</a>";
?>

<?
//removecookie.php removes the cookies

setcookie('mycookie[user_id]', '', '60', '/');
setcookie('mycookie[user_name]', '', '60', '/');

echo "<a href='showcookie.php'>click</a>";
?>

I'm accessing setcookie.php first then going to showcookie.php. I keep getting the "no cookie set" message even though the cookie is there. I've checked my Temporary Internet Files to verify it. Any ideas?

try setting the cookie like this

setcookie ("mycookie[0]", "1", time()+7200);
setcookie ("mycookie[1]", "joe smith", time()+7200);

then to call the cookies to echo them try this

echo $_COOKIE["mycookie"][0];
echo $_COOKIE["mycookie"][1];

hope this helps

Will do. Thanks.

Hang on. That's not really what I was asking. I'm able to call the values. My real question is why is the isset function not working. If I comment that all out, I can see the values. When I put it back in it tells me that there aren't any cookies because

isset($HTTP_COOKIE_VARS['mycookie[user_id]'])

isn't returning anything.

You might try using array_key_exists() instead of isset(), sometimes you can get around NULL values that way.

That said, the problem may well be in the array syntax, although it looks OK.

Do a print_r($COOKIE) and see if the cookies are there but are named something other than you expect. And definitely do:

$testvar=isset($_COOKIE['mycookie[user_id]']);
echo $testvar;

Somewhere around here was a thread on testing with isset() being rather unique...but I can't remember the whole thing...

HTH,

Aw, heck, it could just be your using the literal strings, too.

Try double quotes instead....
