im trying to pass a session between 2 div on the same page. i have links, when i click on one i want the id to pass to the other div to populate it with the info from the link, but it doesnt pass!!

this is the code from my links div

$q =mysqli_query($link, "SELECT * FROM products WHERE status = 1 ORDER BY id DESC");
while($row = mysqli_fetch_array($q)){
$data = $row['image'];
$file = substr($data, strpos($data, "/") + 1);
$_SESSION['id']=$row['id'];

echo"<div class='homedogs'>",
"<a href='merchandise.php' class='productchoice'>",
"<img class='nailthumb-container3' src='$file' alt='{$row['name']}. Image' />",
"</a>",
"<br />",
'NAME: ',$row['name'],"<br />",'PRICE: ',$row['price'],
"</div>";
}
}

and this is other div that i want to use the session in

include 'inc/connect.php';
$q = mysqli_query($link, "SELECT *  FROM products WHERE id = '".$_SESSION['id']."'") or  
                 die (mysql_error());
while($row = mysqli_fetch_array($q)){
$data = $row['image'];
$file = substr($data, strpos($data, "/") + 1);
echo"<div class='rehomediv'>",
"<img class='nailthumb-container2' src='$file' alt='{$row['name']}. Image' />","<br 
  />",
"<div class='nameagesex'>",

"<br />",
"<span class='item_price'>{$row['price']}</span>",
"</div>",

您在循环$_SESSION['id']内多次分配。while这将最终只保留最后一个值，前提是您这样做session_start()，正如您声称的那样。

如果您希望它起作用，请不要使用$_SESSION，而是使用GET查询。将您的链接生成代码更改为：

"<a href='merchandise.php?pid={$row['id']}' class='productchoice'>"

...并且，merchandise.php检查$_GET['pid']以确定所请求的产品 ID：

if(isset($_GET['pid']))
  // show corresponding product (your second listing)
else
  // show something else, i.e. the product catalog (your first listing)
