Gan mau minta saran dong...
lagi bikin Tugas Akhir, lagi tahap pembuatan login. Dengan database berisi colom login dan password aja
Login : admin
Password : 12345
Cuma pas ane test masukin user dengan 'ASD' login malah berhasil
mohon bantuannya...

Untuk index.php:
<div id="template">
<button id="loginbutton">Login</button>
<div style="clear: both"></div>
<div id="login" style="display: none">
<form id="actionlogin" action="login.php" method="post">
<fieldset id="body">
<fieldset>
<label>Username</label>
<input type="text" name="username" id="username" autocomplete="off" />
</fieldset>
<fieldset>
<label>Password</label>
<input type="password" name="password" id="password" autocomplete="off" />
</fieldset>
<button type="submit" id="submitlogin">LOGIN</button>
</fieldset>
<div id="message"></div>
</form>
</div>
</div>

untuk login.php
<?php
$conn = mysql_connect ("localhost","root","");
$db = mysql_select_db ("anime");
$username = $_POST['username'];
$password = $_POST['password'];

$query = "select username,password from login where username like $password and password like $password";
$result = mysql_query($query);
if ($q = 1) {
echo "[removed]alert(Login sukses, $result[username])[removed]";
echo "[removed][removed].href = 'test.php'";
}else{
echo "error";
}
?>


Mohon maaf kalo agak berantakan, masih newbe
