Am was already created form like this and working perfect but on last two forms not working, it displays warning-Undefined variable: reg_no and cost. Am trying to follow algorithm as previous forms but nothing happen. My goal is to update inserted data and here is my form

<?php
@session_start();

if(!isset($_SESSION['b_lname'])){

    echo "<script>window.open('../login.php?not_authorize=<h3>Authentication failure! Please Contact Your System Admin.</h3>','_self')</script>";
}

else {

?>

<?php

include("db_con.php");

$edit_i_id = filter_input(INPUT_GET, 'edit_invoice', FILTER_VALIDATE_INT, ['options' => ['default' => NULL]]);

if(isset($_POST['update'])){ 

    $update_i_id = $edit_i_id;

    //getting the text data from the fields
    $reg_no = $_POST["reg_no"];
    $cost = $_POST["cost"];;

    $update = "update invoice set
    reg_no = '$reg_no', cost = '$cost' where i_id = '$update_i_id'";

    $run = mysqli_query($con, $update);

    if($run)
    {
        echo "<script>alert('An invoice has been updated')</script>";
        echo "<script>window.open('index.php?view_all_customers','_self')</script>";
    }
    else
    {
        echo "<script>alert('There is something wrong! Details not Updated')</script>";
    }

}

?>

If you are updating numbers in your table why you have put the variables in quotes?

$update = "update invoice set reg_no = '$reg_no', cost = '$cost' where i_id = '$update_i_id'";

Am done my friends, Thank you for your cooperation. I remove while loop on that codes and it is working perfectly. here are the codes:

<?php

include ("db_con.php");

if(isset($_GET['edit_invoice'])){
    $edit_i_id = $_GET['edit_invoice'];
    $select_invoice = "select * from invoice where i_id='$edit_i_id'";
    $run_query = mysqli_query($con, $select_invoice);
    $row_invoice = mysqli_fetch_array($run_query);

    $i_id = $row_invoice['i_id'];   
    $reg_no = $row_invoice['reg_no'];
    $cost = $row_invoice['cost'];
}

?>
