I need to redirect users to different pages based on the roles given to them in the database. Only the username and password is submitted on the login page. I have to fetch the role from the database which looks like this:
username | password | role
admin1 admin1 admin
alex12 alex12 (nothing to normal users)Here is the code:
<?php
session_start();
// conectare la baza de date
$db = mysqli_connect("localhost", "root", "", "inregistrare");
if (isset($_POST['login_btn'])) {
$username = mysqli_real_escape_string($db,$_POST['username']);
$password = mysqli_real_escape_string($db,$_POST['password']);
$password = md5($password); // parola cryptata
$sql = "SELECT * FROM users WHERE username='$username' AND password='$password'";
$result = mysqli_query($db, $sql);
if (mysqli_num_rows($result) == 1) {
$_SESSION['message'] = "Te poti Conecta!";
$_SESSION['username'] = $username;
header("location: clasa.php"); //spre o pagina
}else{
$_SESSION['message'] = "Parola gresita!";
}
}
?>
<head>
<title>Conectare</title>
<link rel="stylesheet" type="text/css" href="./css/index-style.css">
</head>
<body>
<?php
if (isset($_SESSION['message'])) {
echo "<div id='error_msg'>".$_SESSION['message']."</div>";
unset($_SESSION['message']);
}
?>
<form method="post" action="clasa.php"> <!-- modifica si aici cand modifici mai sus la php-->
<table align="center">
<tr>
<th id="titlu" class="titlu" colspan="2">Conectare</th>
</tr>
<tr>
<td class="border">Username:</td>
<td class="border"><input type="text" name="username" class="text-input" size="20"></td>
</tr>
<tr>
<td class="border">Password:</td>
<td class="border"><input type="password" name="password" class="text-input" size="20"></td>
</tr>
<tr>
<td class="spatiu"></td>
<td class="spatiu"></td>
</tr>
<tr>
<td><button class="register" type="submit" formaction="./register.php">Inregistrare</button></td>
<td><button class="connect" type="submit" name="login_btn">Conectare</button></td>
</tr>
</table>
</form>
</body>
</html></div>
