[英]get stored Database variables on php login session
i would like to read $Session[] variables on my profile page but im having issues while trying it.我想在我的个人资料页面上读取 $Session[] 变量,但我在尝试时遇到了问题。 this is my php script on my login file
这是我的登录文件中的 php 脚本
<?php
if (isset($_POST['LoginBtn']))
{
$username = $_POST['username'];
$password = $_POST['password'];
if (empty($username) || empty($password))
{
$show -> showError("please fill out all the fields");
}
else
{
$SQLCheckUser = $odb -> prepare("SELECT COUNT(*) FROM `Account` WHERE `username` = :user AND `password` = :password LIMIT 1");
$SQLCheckUser -> execute(array(':user' => $username, ':password' => hash('SHA512', $password)));
$loginCheck = $SQLCheckUser -> fetchColumn(0);
if ($loginCheck)
{
$SQLGetID = $odb -> prepare("SELECT `ID`, FROM `Account` WHERE `username` = :username LIMIT 1");
$SQLGetID -> execute(array(':username' => $username));
$_SESSION['username'] = $username;
$_SESSION['ID'] = $SQLGetID -> fetchColumn(0);
$show -> showSuccess('Willkommen... <meta http-equiv="refresh" content="2;url=index.php">');
}
else
{
$show -> showError('user was not found!');
}
}
}
?>
in the Database on Account i have variables like, username, password, firstname, lastname, adress and i would like to display them on the profile.php page for example like this在帐户数据库中,我有变量,如用户名、密码、名字、姓氏、地址,我想在 profile.php 页面上显示它们,例如像这样
<h4 class="profile-user"><?php echo $_SESSION['firstname']; ?></h4>
<p class="profile-job"><?php echo $_SESSION['lastname']; ?></p>
<p class="profile-job"><?php echo $_SESSION['adress'];?></p>
how could i solve this issue ?我怎么能解决这个问题? page contains a php file starting a session with
页面包含一个开始会话的 php 文件
<?php session_start(); ?>
and a db connection和一个数据库连接
<?php
$show = new show();
$user = new user($odb);
$status = new status($odb);
class show
{
function showError($error)
{
echo '<div class="alert alert-danger"><a class="close" data- dismiss="alert" href="#">×</a><h4 class="alert-heading">error!</h4>'.$error.'</div>';
}
function showSuccess($success)
{
echo '<div class="alert alert-success"><a class="close" data-dismiss="alert" href="#">×</a><h4 class="alert-heading">Login success!</h4>'.$success.'</div>';
}
}
class user
{
var $odb;
function __CONSTRUCT($odb)
{
$this -> odb = $odb;
}
function loggedIn()
{
if (isset($_SESSION['username'], $_SESSION['ID']))
{
return true;
}
else
{
return false;
}
}
function isAdmin()
{
$SQL = $this -> odb -> prepare("SELECT `admin` FROM `Account` WHERE `ID` = :id");
$SQL -> execute(array(':id' => $_SESSION['ID']));
$rank = $SQL -> fetchColumn(0);
if ($rank == 1)
{
return true;
}
else
{
return false;
}
}
}`
my goal is it to display all the database variables of the logged in user on the profile page (Full name, Adress , Phone number) if someone could help me fix my code that would be really appreciated :)我的目标是在个人资料页面上显示登录用户的所有数据库变量(全名、地址、电话号码),如果有人可以帮助我修复我的代码,将不胜感激:)
this page profile.php这个页面 profile.php
session_start();
$dbh = new PDO(" --- connection string --- ");
$user = new user($dbh);
if ($user->loggedIn()) {
$stmt = $odb->prepare("SELECT `firstname`, `lastname`,`adress`,FROM `Account` WHERE ID=$_SESSION['ID'] LIMIT 1");
$stmt->execute();
$row = $stmt->fetch();
}
foreach ($row as $item)
{
<h4 class="profile-user"><?php echo $item['firstname']; ?></h4>
<p class="profile-job"><?php echo $item['lastname']; ?></p>
<p class="profile-job"><?php echo $item['adress']; ?></p>
}
i received an error with this solution, i fixed it by changing the code in the profile.php to this.我收到此解决方案的错误,我通过将 profile.php 中的代码更改为此进行了修复。
<div class="col-lg-3">
<!-- Page Widget -->
<?php
$stmt = $odb->prepare("SELECT 'vorname', 'nachname','email',FROM 'Account' WHERE ID=$_SESSION[ID] LIMIT 1");
$stmt->execute();
$row = $stmt->fetch();
foreach ((array) $row as $item){
$vorname = $item['vorname']; // german word for firstname
$nachname = $item['nachname']; // german word for lastname
$email = $item['email']; // german word for email
} ?>
<h4 class="profile-user"><?php echo $vorname ?></h4>
but it doesnt seem to appear if i reload the screen.但如果我重新加载屏幕,它似乎不会出现。
looks really weird to me对我来说看起来很奇怪
