来自PHP数据库（PDO）的MySQL数据库的自动填充数据（输入字段）

时间：2016-05-28 12:29:45

标签： php mysql html5 pdo

这篇文章包含：

  • 3个PHP页面
  • MySQL表格图片
  • 表单图片

正如标题所说，我需要从数据库 提取一些信息 。

到目前为止，我有以下内容：

  • 索引页＆lt; - 您需要使用个人代码登录此处。 （这是我从联系页面开始获得“会话用户名”的地方）

  • 配置页＆lt; - 用于数据库访问和所有

  • 联系页面＆lt; - 在这里，我想自动填写用户数据。

数据库表包含：

  • 用户名;电子邮件; realName（以及其他一些我不需要的东西）

因此，在联系页面中，我希望看到以下内容：

  • 卡号=用户名（已经有效）

  • 根据用户名自动填写：realName和电子邮件。

也许可以在登录时提取信息并将其存储在POST变量中？但是如何？

数据库：

  • 表格我需要使用：'成员'

members

用户自己提供的信息= 用户名

我需要自动填写的信息= realName 和电子邮件

表格的图片。

电子邮件应该在SESSION语句中，因此我可以向该人发送确认电子邮件，并且应该从数据库输入realName。

这些是当前正在运行的文件：

的config.php：

<?php
ob_start();
session_start();

//set timezone
date_default_timezone_set('Europe/Brussels');

//database credentials
define('DBHOST','*****');
define('DBUSER','*****');
define('DBPASS','*****');
define('DBNAME','*****');

//application address
define('DIR','http://*****/');
define('SITEEMAIL','noreply@*****');

try {

//create PDO connection
$db = new PDO("mysql:host=".DBHOST.";dbname=".DBNAME, DBUSER, DBPASS);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

} catch(PDOException $e) {
//show error
echo '<p class="bg-danger">'.$e->getMessage().'</p>';
exit;
}

//include the user class, pass in the database connection
include('classes/user.php');
include('classes/phpmailer/mail.php');
$user = new User($db);
?>

联系表格：

<?php require('includes/config.php'); 

//if not logged in redirect to login page
if(!$user->is_logged_in()){ header('Location: index.php'); } 
?>

2 个答案:

答案 0 :(得分：1)

已编辑：由于您拥有用户类（例如：$user->is_logged_in()），因此在$_POST[]方法中忽略$_POST['name2']，因为它仍然可以通过DEV工具进行更改，而是更改到$_SESSION['username']（假设这是正确的值）。这比使用HTML字段更可靠。 PHP部分（查询）也有所不同，因为你正在使用PDO，但我无法帮助解决这个问题，因为我使用的是mysqli_，而不是PDO（抱歉），但查询本身应该是类似的

"SELECT * FROM `table` WHERE `number` = '".$_POST['number']."'"

但不要忘记escape your string，否则，您的查询容易受到攻击。

答案 1 :(得分：1)

我解决了这个问题。

在user.php文件中，我已经准备好了所有内容，但我只是不明白为什么它不起作用。

原来是一个简单的错误XD 

<?php
include('password.php');
class User extends Password{

private $_db;
function __construct($db){
    parent::__construct();
    $this->_db = $db;
}
private function get_user_hash($username){
    try {
        $stmt = $this->_db->prepare('SELECT password, username, memberID, realName, email FROM members WHERE username = :username AND active="Yes" ');
        $stmt->execute(array('username' => $username));
        return $stmt->fetch();
    } catch(PDOException $e) {
        echo '<p class="bg-danger">'.$e->getMessage().'</p>';
    }
}
public function login($username,$password){
    $row = $this->get_user_hash($username);
    if($this->password_verify($password,$row['password']) == 1){
        $_SESSION['loggedin'] = true;
        $_SESSION['username'] = $row['username'];
        $_SESSION['memberID'] = $row['memberID'];
        $_SESSION['realName'] = $row['realName']; 
        $_SESSION['email'] = $row['email'];  
        return true;
    }
}

public function logout(){
    session_destroy();
}

public function is_logged_in(){
    if(isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true)    {
        return true;
    }
}
}
?>

我忘记将realName和电子邮件添加到此行:( idiot me：D）

$stmt = $this->_db->prepare('SELECT password, username, memberID, realName, email FROM members WHERE username = :username AND active="Yes" ');
