Re: Cookie Help Required
You need to use the setcookie() function.

Re: Cookie Help Required
Hi visualAd,
Thanks for the tip, i figured it out but now i am facing another problem. I setup 2 cookies...for example:
If user comes to page1.php i set a cookie: testcook1 with value step1
then user is taken to next page page2.php which sets another cookie named testcook2 with value step2
now after all 2 cookies are set i want to display the cookies value:
So the testcook1 is displaying successfully but the testcook2 is not showing its value ...can you please tell me what i am doing wrong with this one ? All the code is same as testcook1...just names changed etc. and still its not working please tell me why..
Thanks

Re: Cookie Help Required
Without seeing code, not sure, but this is a very basic example:
page1.php
PHP Code:
<html>
<head>
</head>
<body>
<?php
$value = 'Test 1';
setcookie("TestCookie", $value);
?>
<a href="page2.php">Next page</a>
</body>
</html>
page2.php
PHP Code:
<html>
<head>
</head>
<body>
<?php
$value = 'Test 2';
setcookie("TestCookie2", $value);
?>
<a href="page3.php">Next page</a>
</body>
</html>
page3.php
PHP Code:
<html>
<head>
</head>
<body>
<?php
echo $_COOKIE['TestCookie'] . "<br>" . $_COOKIE['TestCookie2'];
?>
</body>
</html>
It'd easier to help if you post up your code...

Re: Cookie Help Required
A cookie is probably best described as a small information token. After the cookie has been set by the server, the client sends it back thereafter with each request. The parameters for the setcookie() function allow you to specify the cookies constraints, i.e: path, domain, secure. These tell the client which pages it should pass the cookie back to.
In answer to your question a cookie is valid for all pages within the specified path and/or the domain. If none are given its available globally throughout your site. It is worth however noting that the cookie will not be visible until the page request after you have set it.
If you are thinking of storing a lot of information inside the cookie, or find yourself needing more than one, or will be using it to identify users then I would recommend you use PHP's built in session module instead.

Re: Cookie Help Required
Yes, when you start a session for the first time it attempts to set a cookie, so you should use the session_start() function like you would use the setcookie() function.

That code will not work, because you have called the setcookie() function after output as started. It should be at the very top of the page before and other echo or print statements and before and HTML.
