如何在同一个表的另一个字段上填充一个字段的值

标签： php html mysql

我有一个表，其中包含“客户注册”，“更新帐单地址”和“更新收货地址”一组字段。注册后，用户将填写“客户注册”。

我希望此字段（“客户注册”）上的值自动填充在“更新帐单地址”和“更新送货地址”上，而不是手动填写两个字段。请注意，这些是不同的字段，但是在数据库的同一表上。

我该如何实现？如果这个问题太基础了，请原谅我，我试图从上一篇文章中找到答案，但无法获得我想要的。 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

    $valid = 1;

    if(empty($_POST['cust_name'])) {

                        <input type="submit" class="btn btn-primary" value="<?php echo LANG_VALUE_5; ?>" name="form1">

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

我希望cust_name, cust_cname, cust_phone, cust_country, cust_address, cust_city, cust_state, cust_zip的值填充在等效字段上。如果你明白我的意思。

答案 0 :(得分：0)

答案在您的代码中

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

最后一个foreach是一个cicle，它在所有结果表上运行，因此，如果要更新filds，则需要将“ question”更改为要查询的表，然后在cicle上将它们存储在我猜想正确的变量cust_name，cust_cname，cust_phone，cust_country，cust_address，cust_city，cust_state，cust_zip。

祝你好运
