php counter and check whether cookies are enabled or disabled and if disabled post it

[petergi]

hi i want to create a php and check cookies if they are enabled or disabled then if enables i want to proceed to this code

<?php
$dir = "img";

$file = "counter.txt";

$cookie_name = "my_cookie_name";
$cookie_value = "my_cookie_value";
$cookie_life = "900";

if(!file_exists("$file"))
{
$fp=fopen("$file","a");
fputs($fp,"0");
fclose($fp);
}

$alt = 'alt=""';

$fp=fopen($file,"r+");
$hits=fgets($fp,10);

if(!isset($_COOKIE["$cookie_name"]))
{
$hits++;
fseek($fp,0);
fputs($fp,$hits);
setcookie($cookie_name, $cookie_value, time()+$cookie_life, "");
}
fclose($fp);

echo $hits;
?>

as you can see i have the counter.But i want to echo a message if cookies disabled and dont count +1 in the counter. What changes should i make?

Set a cookie on one page, and check for it on the next. If it's not there, then the user must have cookies disabled.

in next page?the site is a one page site with information...no links and a simle counter.I just want to hit everyone that comes to the site and hit again if the same person comes again in 15 minutes.But if he has cookies disabled i dont want counter to hit. this code is ccode.php that calls this code that you answered too 🙂

By "next page" I simply meant "next page load." You can't tell anything about what a client is doing with cookies until at least two page loads. On the first, you use [man]setcookie/man to send the cookie to the client along with that page. Note that at this point, $COOKIE is empty since no cookies have been received yet. On the second page load, $COOKIE will be populated if the client returns the cookie information... otherwise, it'll still be empty and you'll know that the client rejected the cookie.

if all you are only interested in is the statistics, then google analytics or a log analyser will give you the data without you having to write anything.
