Cookie Recognising

NZ_Kiwis

I've set a cookie to my computer when a user logs in and selects to save their details. How do I now write a code which tells if there is a cookie and will start a session??

I guess the first part of this is to get the cookie information, how is this done???

With $_COOKIE

NZ_Kiwis

This is my cookie
RLNZkiwiswww.site.com/login/153614007420162954444212198034531429731546*

This is my PHP
<?php
echo $_COOKIE["RLNZ"];
echo $HTTP_COOKIE_VARS["RLNZ"];
?>
But nothing is displayed... why???

Give the simplest and smallest script that demonstrates your problem.

How about the one above. I should echo my cookie. but it doesn't.... I don't know why

laserlight

You havent set your cookie yet.

NZ_Kiwis

sorry this is the code for that

if ($auto == '1') {
$value = $_POST["username"];
setcookie("RLNZ", $value, time()+3600);

Where does $auto and $_POST["username"] come from?
Basically, keep all the extra stuff away until you're sure that you got the basics working.

Test with something like this:

<?php
if (isset($_COOKIE['testcookie'])) {
	echo 'Cookie: ' . $_COOKIE['testcookie'];
} else {
	setcookie("testcookie", "cookie data", time() + 3600);
	echo 'Refresh the page';
}
?>

Yes, that's the entire script.

NZ_Kiwis

if ($auto == '1') {
$value = $_POST["username"];
setcookie("RLNZ", $value, time()+3600);

Auto is to see if they want a cookie set. $_POST["username"] is the username they enter when they sign in.....

Looking at the cookie
RLNZkiwiswww.site.com/login/1536140074201629544442121......
It seems to get the username "Kiwis" but it still does not echo, I don't know why??

NZ_Kiwis

Okay reason being is the has the url of site.com/login
So to do a cookie test I would need to have a script looking into the folder

BUT

When i'm in the login folder and I do a script echo $_COOKIE["RLNZ"]; is works,

if i'm on my main page to a
require("login/echocode.php");
It does not find the cookie.

How can I fix this?

What I'm trying to do is find a cookie and if it's set then log a user in starting a session with session_start();

I thought i would only need one cookie for when they logged in.... would this be right???

Check out the 4th parameter to setcookie().
