Cookies

Anon

Heh, my third post in two days... I just need a lot of help or something...

Anyway, now I'm dealing with cookies. I have a script that sets some cookies based upon whether the user has any of my cookies on the hard drive already.
My setcookie call:
setcookie("visitor", $new_id, $the_time, "/", "www.domain.com", 0);
$new_id is just an integer and $the_time is a string created by gmdate();

The cookie is stored on the harddrive (I can see them in c:\windows\cookies on my machine) but when I call the very same script which does if(isset ($visitor)) it always fails.
Anyone have any ideas about this?

Thanks a bunch everyone,
Ross

That's because cookies aren't accessed this way.

Try

(Argh! Hit the wrong button!)

That's because cookies aren't checked this way.

Try this:

$visitor=$HTTP_COOKIE_VARS["visitor"];

$visitor should have what you want.

I want to set cookieS in my site using PHP but I just don´t get to it. Could you help me guys?

To learn about setting cookies, see

http://www.php.net/manual/function.setcookie.php

Get to know php.net. The manual they have their is well-written, and to fill in the spots that are weak, they've got a feedback forum at the bottom!

Buddys,

My setcookie just don´t work at once! Please, watch my code...

SetCookie("cript",$cript,time()+300,"/","",1);
SetCookie("log",$log,time()+300,"/","",1);

and tell me what´s wrong... :-(

I can´t retrieve it also, when in a new page...

Ps.: I´ve read the whole manual of php.net (about cookies).

Thanks.

When you set a cookie, it DOESN'T work immediately. The cookie value will be present at the next page access.

For example,

example.php:
<?

$value='a';

setcookie("name", $value);

echo "<A HREF=example.php> try again </A> \n";

echo "<BR> Value: $HTTP_COOKIE_VARS(name)\n";

?>

Will return

try again
Value:

the first time, but will return

try again
Value: a

when you click on the hyperlink.

If you need the values right away, use a standard naming convention for your variables. Something like this:

$value read from previous form submission

#only setcookie if $value was submitted...
if (isset($value))
{ setcookie("name", $value); }

$value not set, get from cookie.

else { $value=HTTP_COOKIE_VARS(name); }

echo "<A HREF=example.php> try again </A> \n";

echo "<BR> Value: $value\n";

If e can presume that you are relying on the cookie to provide this value, so we pull from the cookie.

Otherwise, we're setting the value from $value and using it right away.

Hope this helps...

For those of you like me who found this v.difficult to understand here is simple version which creates and kills a cookie

?

if($cookieset==yes) { 
	// set cookie contents
     setcookie("atltest",$myval,(time() + 1800));
	 header("Location: $PHP_SELF");
}

if($logout==yes) {
	setcookie("atltest","");
	echo "deleted the cookie<br><br>";
	?> <a href="index.php3">Next</a> <?
}
