listrecord.php does not contain a form, so what you send to update.php is just the id through the link, so in update.php change $id=$_POST['id']; to $id=$_GET['id']; and remove the others $_POST, they are not defined.

"UPDATE web_members SET name='$name', lastname='$lastname', email='$email' WHERE id='$id'";

$PDO_con = new PDO; // Create DB connection
$sql = "UPDATE web_members SET name='$name', lastname='$lastname', email='$email' WHERE id='$id'";
$q = $PDO_con->prepare($sql);
$q->execute; // Execute cmd
