Can someone please help me? My username is Blimeo and my password is "password" but when I put my credentials in, it says "Access denied" like I told it to. I am 100% sure that I configured my mySQL database correctly.
<html>
<body>
<?php
echo sha1('Blimeo');
if (isset($_REQUEST['attempt'])) {
$link = mysql_connect('localhost', 'root', 'password') or die('Could not connect to database');
$user = mysql_real_escape_string($_POST['user']);
$password = sha1(mysql_real_escape_string($_POST['password']));
mysql_select_db('test_users');
$query = mysql_query(
"SELECT user
FROM users
WHERE user = '$user'
AND password = '$password'
") or die(mysql_error());
mysql_fetch_array($query);
$total = mysql_num_rows($query);
if ($total > 0) {
session_start();
$_SESSION['user'] = 'blah';
header('location: dashboard.php');
}
else {
echo '<br>Access denied!';
}
}
?>
<form method="post" action="login.php?attempt">
Enter your username:<input type="text" name="user"/><br/>
Enter your password:<input type="password" name="password"/><br/>
<input type="submit"/>
</form>
</body>

Php login script is used to provide the authentication for our web pages. the Script executes after submitting the user login button.
php session_start(); /*This is the equivalent of login.
Insert admin login information: Here, we are inserting two records in our table. You can add as many as you want. Or copy and paste the following code to insert records into the SQL panel. INSERT INTO `adminlogin` (`id`, `username`, `password`) VALUES (NULL, 'admin', 'admin'), (NULL, 'admin2', 'admin2');
UPDATE, 2016
Please only use existing login systems, which are provided out-of-the-box in nearly every PHP framework! There's absolutly no reason to write this by yourself, as user authentication is a big topic and it will take months (years) to write a serious, stable and modern login solution.
ORIGINAL TEXT, FROM 2012:
As login systems are a security issue and EVERYBODY makes the same mistakes over and over again, i can clearly say:
Take a professional script and work through the code to understand whats happening, what hashing and salting is and what problems session can have.
