Post problem regarding cookies.

Another questoin after two answered questions. Okkk! This is the problem regarding cookies. where i am creating a mysql table and storing the information of each visit by the browsers. if browser has visited the site. it will treat that as old user. else it will insert the information of new user in database. But the problem is: " Every time it is creating a new row in table and treating each attempt as a new attempt." Can any one help me about this? I am sending the format of the database also. Try it............

create table track_visit (
first_visit INT,
last_visit INT,
num_visits INT,
total_duration INT,
total_clicks INT

************************************************** ************************************************** ****************
$link = mysql_connect( "localhost", "root", "root" );
if ( ! $link )
die( "Couldn't connect to mysqld" );
mysql_select_db( "test", $link ) or die ( mysql_error() );
if ( ! isset ( $visit_id ) ) {

$user_stats = newuser( $link );
else {
$user_stats = olduser( $link, $visit_id, $slength );
print "Welcome back $visit_id<P>";

function newuser( $link )
// a new user!
$visit_data = array (
first_visit => time(),
last_visit => time(),
num_visits => 1,
total_duration => 0,
total_clicks => 1

// $visit_data[id] = mysql_insert_id();
// setcookie( "visit_id", $visit_data[id], time()+(60*60));

$query = "INSERT INTO track_visit ( first_visit,
total_clicks ) ";
$query .= "values( $visit_data[first_visit],
$visit_data[total_clicks] )";
$result = mysql_query( $query );
$visit_data[id] = mysql_insert_id();
setcookie( "visit_id", $visit_data[id], time()+(60*60),"/");
echo "<script type=text/javascript>window.alert(\"Finish of the line.\")</script>";
return $visit_data;
function olduser( $link, $visit_id, $slength )
// s/he's been here before!
$query = "SELECT * FROM track_visit WHERE id=$visit_id";
$result = mysql_query( $query );
if ( ! mysql_num_rows( $result ) )
// cookie found but no id in database -- treat as new user
return newuser( $link );
$visit_data = mysql_fetch_array( $result, $link );
// there has been another hit so increment
if ( ( $visit_data[last_visit] + $slength ) > time() )
// still in session so add to total elapsed time
$visit_data[total_duration] +=
( time() − $visit_data[last_visit] );
// this is a new visit
// update the database
$query = "UPDATE track_visit SET last_visit=".time().",
num_visits=$visit_data[num_visits], ";
$query .= "total_duration=$visit_data[total_duration],
total_clicks=$visit_data[total_clicks] ";
$query .= "WHERE id=$visit_id";
$result = mysql_query( $query );
return $visit_data;
************************************************** ************************************************** ****************

OK, you are using ID field in your database to identify unique users which is wrong because after each insert a new one will be created.

rather use

$id = session_id();

using session_id() the id will remain the same until the browser is closed.

Kind regards.

found you are not reading the cookie value in the else clause

see this page http://php.net/manual/en/reserved.variables.cookies.php

and you need to read the $visit_id from variable $_COOKIES['visit_id']

hope that helps.

kind regards.
