Cookie Problem

katkurisrinivas

Hello,
See this Cookie Code and Iam getting errors. But it should work fine. I taken it from book only.

===========================================
<?php
$days = 1;
$expires = time()+($days * 86400);

if($sitevisits) {
$sitevisits++;
// now we need to set the cookie with the new value
setcookie("sitevisits", $sitevisits, $expires);
} else {
// this must be a new visitor, so set initial cookie
setcookie("sitevisits", 1, $expires);
}
?>

<BODY>
<script language="php">
print("Thank you for visiting this page $sitevisits times!");
</script>
</BODY>

============================================
Iam Getting the following error in my browser:

Warning: Undefined variable: sitevisits in C:\Inetpub\wwwroot\creatriznet_new\dbin.php on line 5

Warning: Cannot add header information - headers already sent by (output started at C:\Inetpub\wwwroot\creatriznet_new\dbin.php:5) in C:\Inetpub\wwwroot\creatriznet_new\dbin.php on line 11

Warning: Undefined variable: sitevisits in C:\Inetpub\wwwroot\creatriznet_new\dbin.php on line 18
Thank you for visiting this page times!

So please see this code and check any wrong in the code of cookies.

I think, there is no wrong but it is not working in my system. May be other reasons
So please just check it and reply.

Hi
I saw ur problem.There seems to be in checking condition.

Instead of 'if($sitevisits)'
check the condition like this:
'if(isset($sitevisits)) {
........
}
else {
.....
}

go ahead!..

The other thing is that you have your error warning level turned up very high - so high that if you use a variable without it being set it generates a warning message about an "undefined variable".

Then, once it's generated and sent that warning message to the browser, it can't set a cookie (things like setting cookies that involve headers have to be done before anything else is sent to the browser). As a result, it complains about not being able to send any more header information.

Either change the error_reporting setting in your php.ini file to something like E_ALL & ~E_NOTICE (it's the "& ~E_NOTICE" that turns the uninitialised variable warnings off), or do it at the start of your script with

error_reporting(E_ALL & ~ENOTICE);

Please Can u see this code in ASP,
I want the same code in PHP. Then my problem will be solved.

ASP code:

<%
SiteVisited=Request.ServerVariables("server_name")
present_page = Request.ServerVariables("SCRIPT_NAME")
if Request.Cookies("HitCount")(present_page) <> "Visited" then

rs("PageVisited") = present_page 
rs("SiteVisited") = SiteVisited
    if Request.Cookies("SiteCount")(SiteVisited) <> "Visited" then 
	   rs("HitCount") = 1
	   Response.Cookies("SiteCount")(SiteVisited) = "Visited"
	end if

Response.Cookies("HitCount")(present_page) = "Visited"

end if
%>
