我正在尝试为使用Twig的网站进行用户登录,我拥有所有适用于基于php的网站的php登录文件,
我正在尝试找到将php登录变量(会话和用户名)传递到树枝模板的正确方法。
我为twig添加了扩展名,以便$ _SESSION可以使用以下代码在我的.twig文件上运行:
public function getGlobals() {
return array(
'session' => $_SESSION,
) ;
}
但是我仍然不知道如何在不将server.php包含在php include中的情况下,将$ _SESSION传递到我的树枝模板(显然不起作用)。
将会话传递到树枝模板的正确方法是什么?
下面的Server.php:
<?php
session_start();
// initializing variables
$username = "";
$email = "";
$errors = array();
// connect to the database
$db = mysqli_connect('host', 'user', 'pass', 'dbname');
// REGISTER USER
if (isset($_POST['reg_user'])) {
// receive all input values from the form
$username = mysqli_real_escape_string($db, $_POST['username']);
$email = mysqli_real_escape_string($db, $_POST['email']);
$password_1 = mysqli_real_escape_string($db, $_POST['password_1']);
$password_2 = mysqli_real_escape_string($db, $_POST['password_2']);
// form validation: ensure that the form is correctly filled ...
// by adding (array_push()) corresponding error unto $errors array
if (empty($username)) { array_push($errors, "Username is required"); }
if (empty($email)) { array_push($errors, "Email is required"); }
if (empty($password_1)) { array_push($errors, "Password is required");
}
if ($password_1 != $password_2) {
array_push($errors, "The two passwords do not match");
}
// first check the database to make sure
// a user does not already exist with the same username and/or email
$user_check_query = "SELECT * FROM users WHERE username='$username' OR
email='$email' LIMIT 1";
$result = mysqli_query($db, $user_check_query);
$user = mysqli_fetch_assoc($result);
if ($user) { // if user exists
if ($user['username'] === $username) {
array_push($errors, "Username already exists");
}
if ($user['email'] === $email) {
array_push($errors, "email already exists");
}
}
// Finally, register user if there are no errors in the form
if (count($errors) == 0) {
$password = password_hash("$password_1", PASSWORD_DEFAULT);//encrypt
the password before saving in the database
$query = "INSERT INTO users (username, email, password)
VALUES('$username', '$email', '$password')";
mysqli_query($db, $query);
$_SESSION['username'] = $username;
$_SESSION['success'] = "You are now logged in";
header('location: /');
}
}
// ...
// LOGIN USER
if (isset($_POST['login_user'])) {
$username = mysqli_real_escape_string($db, $_POST['username']);
$password = mysqli_real_escape_string($db, $_POST['password']);
if (empty($username)) {
array_push($errors, "Username is required");
}
if (empty($password)) {
array_push($errors, "Password is required");
}
if (count($errors) == 0) {
$query = "SELECT * FROM users WHERE username='$username'";
$result = mysqli_query($db, $query);
if (mysqli_num_rows($result) === 1) {
$user = mysqli_fetch_assoc($result);
if (password_verify($password, $user['password'])) {
$_SESSION['username'] = $username;
$_SESSION['success'] = "You are now logged in";
header('Location: /');
die();
}
}
array_push($errors, "Wrong username/password combination");
}
}
?>
