php - Index.php 登录功能修复
问题描述
我有一个使用 loginfunc 函数的 index.php，它可以让用户登录。但奇怪的是，当您单击登录时，什么也没有发生。下面是 index.php 的代码。我无法弄清楚问题是什么，因为我没有收到错误消息，也没有看到错误，因此什么也没发生。
<?php
require_once('functions/loginfunc.php');
include_once("globals.php");
$username = $_POST['username'];
$passwort = $_POST['passwort'];
if (isset($_POST['register'])) {
header("Location: /register.php");
}
if (isset($_POST['login'])) {
loginfunc();
}
?>
<html>
<head>
<script type="text/javascript">
document.getElementById("registerbutton").onclick = function () {
location.href = "/register.php";
};
</script>
<link rel="stylesheet" type="text/css" href="stylesheet.css">
<title> Coiffure Creation Login </title>
</head>
<body>
<a href="index.php">
<img src="https://doriansandbox.toolmaster.ch/images/creation-coiffure-logo-neu.png" align="middle">
</a>
<div id="login">
<form method="POST" action="">
Username:<br>
<img src="/images/figure.png" alt="Icon" height="42" width="42>">
<input type="text" name="username"><br>
Passwort:<br>
<img src="/images/Key_lock.png" alt="Icon" height="42" width="42>">
<input type="password" name="passwort"><br>
<input type="submit" name="login" value="Login" />
<input type="submit" name="register" value="Neuen User erstellen" />
</form>
</div>
</body
</html>
和登录函数
<?php
function loginfunc() {
session_start();
include 'globals.php';
if(empty($_POST["username"]) || empty($_POST["passwort"]))
{
echo "Bitte tragen Sie Ihr Passwort und Benutzername ein";
}
else {
$query = "SELECT * FROM benutzer WHERE username = '$username'";
$result = mysqli_query($con, $query);
if(mysqli_num_rows($result) > 0)
{
while($row = mysqli_fetch_array($result))
{
if(password_verify($passwort, $row["password"]))
{
session_start();
$_SESSION['username'] = $username;
header("Location:dashboard.php");
}
else
{
echo "Kevin";
}
}
}
else
{
}
}
}
?>
