如何在同一个表的另一个字段上填充一个字段的值

Question

I have a table that has "customer registration" "Update Billing Address" and "Update Shipping Address" a group of fields. Upon registration the user fills the "customer registration".

I'd like the values on this field ("customer registration") to be populated automatically on "Update Billing Address" and "Update Shipping Address" instead of filling both fields manually. Note these are different fields but on same table in the Database.

How do I achieve this? Please pardon me if this question is too elementary, I've tried to find the answer here from previous post but can't get what I want. enter image description here

<?php require_once('header.php'); ?>

<?php
// Check if the customer is logged in or not
if(!isset($_SESSION['customer'])) {
    header('location: '.BASE_URL.'logout.php');
    exit;
} else {
    // If customer is logged in, but admin make him inactive, then force logout this user.
    $statement = $pdo->prepare("SELECT * FROM tbl_customer WHERE cust_id=? AND cust_status=?");
    $statement->execute(array($_SESSION['customer']['cust_id'],0));
    $total = $statement->rowCount();
    if($total) {
        header('location: '.BASE_URL.'logout.php');
        exit;
    }
}
?>

<?php
if (isset($_POST['form1'])) {

    $valid = 1;

    if(empty($_POST['cust_name'])) {
        $valid = 0;
        $error_message .= LANG_VALUE_123."<br>";
    }

    if(empty($_POST['cust_phone'])) {
        $valid = 0;
        $error_message .= LANG_VALUE_124."<br>";
    }

    if(empty($_POST['cust_address'])) {
        $valid = 0;
        $error_message .= LANG_VALUE_125."<br>";
    }

    if(empty($_POST['cust_country'])) {
        $valid = 0;
        $error_message .= LANG_VALUE_126."<br>";
    }

    if(empty($_POST['cust_city'])) {
        $valid = 0;
        $error_message .= LANG_VALUE_127."<br>";
    }

    if(empty($_POST['cust_state'])) {
        $valid = 0;
        $error_message .= LANG_VALUE_128."<br>";
    }

    if(empty($_POST['cust_zip'])) {
        $valid = 0;
        $error_message .= LANG_VALUE_129."<br>";
    }

    if($valid == 1) {

        // update data into the database
        $statement = $pdo->prepare("UPDATE tbl_customer SET cust_name=?, cust_cname=?, cust_phone=?, cust_country=?, cust_address=?, cust_city=?, cust_state=?, cust_zip=? WHERE cust_id=?");
        $statement->execute(array(
                    strip_tags($_POST['cust_name']),
                    strip_tags($_POST['cust_cname']),

            </div>
        </div>
    </div>
</div>

I expect the value of the cust_name, cust_cname, cust_phone, cust_country, cust_address, cust_city, cust_state, cust_zip to populate on the equivalent fields. If you understand what I mean.

Answer 1

The answear is in your code:

$statement = $pdo->prepare("SELECT * FROM tbl_country ORDER BY country_name ASC");
$statement->execute();
$result = $statement->fetchAll(PDO::FETCH_ASSOC);
foreach ($result as $row){ }?>

The last foreach is a cicle it runs on all the result table, so if you want to update the filds, you need to change the "question" to the table you want to query and then on the cicle store them in the correct variables cust_name, cust_cname, cust_phone, cust_country, cust_address, cust_city, cust_state, cust_zip i suppose.

Good Luck
