Select and Insert Cannot save session in database base - php

Question

how can I get the selected database into second page, And insert into another table.
Here is my first page :
<?php
session_start();
$result = mysqli_query($con,"SELECT * FROM qwerty
WHERE ID LIKE '$id' ");
while($row = mysqli_fetch_array($result))
{
echo "Name:" . $row['Fname'] . " " . $row['Lname'];
}
$_SESSION['fname']=$row['Fname'];
$_SESSION['lname']=$row['Lname'];
?>
Here is my second page:
<?php
session_start();
$sql="INSERT INTO login (Fname, Lname)
VALUES
('{$_SESSION['fname']}','{$_SESSION['lname']}')";

Answer 1

$sql="INSERT INTO login set
Fname='".$_SESSION['fname']."',
Lname='".$_SESSION['lname']."'";

Answer 2

Please look and try the following:
session_start();
$firstName = $_SESSION['fname'];
$lastName = $_SESSION['lname'];
$sql="INSERT INTO `login` (Fname, Lname) VALUES ('$firstName','$lastName')";
Also ensure that when you populate the sessions
while($row = mysqli_fetch_array($result))
{
echo "Name:" . $row['Fname'] . " " . $row['Lname'];
}
$_SESSION['fname']=$row['Fname']; //CHECK
$_SESSION['lname']=$row['Lname'];
that there are data assigned. Maybe add it in the loop. If you are looking for the last record it will be assinged anyway:
while($row = mysqli_fetch_array($result))
{
echo "Name:" . $row['Fname'] . " " . $row['Lname'];
$_SESSION['fname']=$row['Fname']; //CHECK
$_SESSION['lname']=$row['Lname'];
}
