Hello,
I created a php script in which I call php fumcion which looks like
this
function confirm($vl) {
?>
<head>
<script type='text/javascript'>
<!--
document.cookie = "qrv=''";
alert(document. cookie);
var answer = confirm("ARE YOU SURE?")
if (answer){
alert('ok');
document.cookie = "qrv=yes";
alert(document. cookie);
}
else{
alert('no');
document.cookie = "qrv=no";
alert(document. cookie);
}
//-->
</script>
</head>
<?
}
Later after I call the above function I want to check what is the
session value
echo $_COOKIE["qrv"];
it is null, but the actual cookie in the browser is set to yes or no.
When I try again the echo command give me the right output.
Problem is that I always have to refresh the webpage in order to get
the cookie value.
It looks like php reads the cookie that was set before you load the
browser page.
Any ideas how to fix that?
Thank You

It's the old story:
Javascript runs on the users computer, PHP on the server. PHP sends output
"as is" to the client, with the variables available.
Because the cookie is set AFTER the user has gotten the page, at the time
the page was set this cookie variable wasn't available. No way to "fix"
that, that's just how it works. If you need this functionality, it needs a
different approach. Either create the dynamic content using javascript (for
instance XMLHTTPRequest) , or let the user go to a different page.
Grtz,

Hi all.
I'm trying to set a cookie expiry date but my script is JS (JavaScript). I've
tried
Response.Cookies("Test").Expires = Date();
Response.Cookies("Test").Expires = Date().toLocaleString();
Response.Cookies("Test").Expires = Date().toString();
Response.Cookies("Test").Expires = Date().toUTCString();

Server sends cookie to browser and the browser send the same cookie
back to the server according to Wikipedia.
Do browsers send even javascript-generated cookie to servers?
For example, if I browse to a page on a server and if the content of
the page is the following:
<html>
<head><script>
alert(document.cookie);

Hi -
I'm trying to use javascript to determine if a user's browser has cookies enabled or not.
To test: copy this code into a file with a 'html' extension, and load it into your IE browser directly, through a local web server and through a remote web server.
By turning cookies on/off in your browser, running the file, then clicking the 'test1' or 'test2' buttons, the displayed text should accurately inform you if your cookies are On or...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
