value of a cookie.

[knuff]

What is the easiest way to get a value from a cookie when I’m using a if. Or better yet, check if there is a cookie at all using if. Like this: if the value of the cookie OR if there is a cookie by the name of XXX then do this. Else don’t bother.

Example:

if($_COOKIE['the_cookie_name']) {
$do_something;
}

or

if($_COOKIE['the_cookie_name'] == $condition) {
$do_something;
} else {
$do_something_else;
}

The if doesn't loop btw 😉

so why dose not this work

if (!isset($COOKIE['terre']))
{
$rostat="nej";
setcookie("terre", $rostat, time()+3600*1000);
}

else
{
echo 'cookie is there';
}

evry time I reload its always creates a new cookie

Possibly because of this line:

if (!isset($COOKIE['terre']))

// should be

if (!isset($_COOKIE['terre']))

dosent matter, still dosent work, Now it wont set the cookie it always echo-out is there.

Erm.. yes, that's because the cookie works 😉

If you want to unset the cookie for testing again, try:

setcookie("terre", "", time()-3600*1000);

Remember also that when the cookie is set, you need to refresh the page an extra time to access the cookie data. They will not be accessible on the cookie-setting.

well it always echo-out is there even if i delete the cookie and refresh it 10 times.

Try to have it echo the value of the cookie:
echo $_COOKIE['terre'];

Does it display?

[edit] Beat to it! [/edit]

Then when it echos out, echo the value of the cookie. If the cookie truly is not set, you will not see the value. If the cookie still exists for some reason, the value of the cookie will be displayed...

// Here is an example of what I mean
if (!isset($_COOKIE['cookie'])) {

// set cookie...

}
 else {
    echo "Cookie is already set. \n<br>\n";
    echo "The cookie's value is: ".$_COOKIE['cookie'];
 }

[knuff]

Ok, this is the output:

Cookie is already set. 
The cookie's value is:

when Im usign this:

if (!isset($_COOKIE['terre'])) {
$rostat = "nej";
setcookie("terre", $rostat, time()+3600*1000);

}
 else {
    echo "Cookie is already set. \n<br>\n";
    echo "The cookie's value is: ".$_COOKIE['terre'];
 }

so it says thats there is one but it isnt.

if i use

if (!$_COOKIE['terre'])

then the value becomes "nej" even if there is no cookie at all on my cpu...

strange..

[mogster]

Try to calculate the time before setting it in the cookie. Create two scripts in the same dir, one that sets cookie, one that unsets it:

## Set cookie ##
if (!isset($_COOKIE['terre'])) {
$rostat = "nej";
$cTime = time()+(3600*1000);
setcookie("terre", $rostat, $cTime);
header("Location:".$PHP_SELF."");
}
 else {
    echo "Cookie is already set. \n<br>\n";
    echo "The cookie's value is: ".$_COOKIE['terre'];
 }

and

## Unset cookie ##
if (isset($_COOKIE['terre'])) {
$rostat = "";
$cTime = time()-(3600*1000);
setcookie("terre", $rostat, $cTime);
header("Location:".$PHP_SELF."");
}
 else {
    echo "The cookie is now unset";
    echo "The cookie's value is: ".$_COOKIE['terre'];
 }

Then access the scripts and try out. The header-statement will refresh the page once, and this is needed to see the cookie value displayed/removed.
