php - php中的表单数据没有更新到mysql表

标签 php html mysql

我有一个登录网站，用户可以使用存储在数据库中的电子邮件和密码进行注册，用户注册后，他可以登录并转到个人资料页面，并根据需要填写额外的详细信息。个人资料页面如下所示:

<?php
  require_once "server.php";

  if (!isset($_SESSION['username'])) {
  	$_SESSION['msg'] = "You must log in first";
  	header('location: login.php');
  }

?>

现在，当用户向表单添加任何数据时，它不会被更新，并且会显示以下错误:

Notice: Undefined index: phone in C:\xampp\htdocs\vendor\profile.php on line 174

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\vendor\profile.php:10) in C:\xampp\htdocs\vendor\profile.php on line 179

现在的问题不是错误，问题是为什么我的数据没有添加到数据库中，任何人都可以告诉我我的代码有什么问题吗？

(注意:我知道这段代码容易受到 SQL 注入(inject)，这样做是为了测试目的)

最佳答案

更新数据不起作用，因为您将所有输入名称值设置为 cc- payment name="cc- payment"。每个输入的它应该是唯一的。根据您的帖子请求，它应该是这样的:

考试:

<div class="form-group">
<label for="full_name_label" class="control-label mb-1">Full Name</label>
<input id="full_name_label" name="full_name" type="text" class="form-control" aria-required="true" aria-invalid="false" >
</div>

<div class="form-group has-success">
<label for="phone_label" class="control-label mb-1">Phone</label>
<input id="phone_label" name="phone" type="text" class="form-control" aria-required="true" aria-invalid="false" value="">
</div>

在 php 中:你可以获得值

$fullname = $_POST['full_name'];
$email = $_POST['phone'];

希望你能理解。 :)
