What are the potential pitfalls of using sessions for passing values in PHP popups?

One potential pitfall of using sessions for passing values in PHP popups is that it can lead to security vulnerabilities, such as session hijacking or session fixation attacks. To solve this issue, it is recommended to use POST or GET requests to pass values between pages instead of relying on sessions. 

// Using POST method to pass values between pages

// Page 1: Form submission
<form action="page2.php" method="post">
    <input type="hidden" name="value" value="example">
    <button type="submit">Submit</button>
</form>

// Page 2: Receiving the value
<?php
if(isset($_POST['value'])){
    $value = $_POST['value'];
    echo "Value passed from page 1: " . $value;
}
?>
