I decided to make a recent view box that allows users to see what links they clicked on before. Whenever they click on a posting, the posting's id gets stored in a cookie and displays it in the recent view box.
In my ad.php, I have a definerecentview function that stores the posting's id (so I can call it later when trying to get the posting's information such as title,
price from the database) in a cookie. How do I create a cookie array for this?
**EXAMPLE:** user clicks on ad.php?posting_id='200'
//this is in the ad.php
function definerecentview()
{
$posting_id=$_GET['posting_id'];
//this adds 30 days to the current time
$Month = 2592000 + time();
$i=1;
if (isset($posting_id)){
//lost here
for($i=1,$i< ???,$i++){
setcookie("recentviewitem[$i]", $posting_id, $Month);
}
}
}
function displayrecentviews()
{
echo "<div class='recentviews'>";
echo "Recent Views";
if (isset($_COOKIE['recentviewitem']))
{
foreach ($_COOKIE['recentviewitem'] as $name => $value)
{
echo "$name : $value <br />\n"; //right now just shows the posting_id
}
}
echo "</div>";
}
How do I use a for loop or foreach loop to make it that whenever a user clicks on an ad, it makes an array in the cookie? So it would be like..
1. clicks on ad.php?posting_id=200 --- setcookie("recentviewitem[1]",200,$month);
2. clicks on ad.php?posting_id=201 --- setcookie("recentviewitem[2]",201,$month);
3. clicks on ad.php?posting_id=202 --- setcookie("recentviewitem[3]",202,$month);
Then in the displayrecentitem function, I just echo however many cookies were set?
I'm just totally lost in creating a for loop that sets the cookies. any help would be appreciated
