This is a snapshot of my db: link link
db.php
<?php
$con = mysqli_connect("localhost","root","","organisation");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
login.php
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Login</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<body>
<?php
require('db.php');
session_start();
// If form submitted, insert values into the database.
if (isset($_POST['username'])){
// removes backslashes
$username = stripslashes($_REQUEST['username']);
//escapes special characters in a string
$username = mysqli_real_escape_string($con,$username);
$password = stripslashes($_REQUEST['password']);
$password = mysqli_real_escape_string($con,$password);
//Checking is user existing in the database or not
$query = "SELECT * FROM admin WHERE username='$username'and password='".md5($password)."'";
$result = mysqli_query($con,$query) or die(mysql_error());
$rows = mysqli_num_rows($result);
if($rows==1){
$_SESSION['username'] = $username;
// Redirect user to index.php
header("Location: index.php");
}else{
echo "<div class='form'>
<h3>Username/password is incorrect.</h3>
<br/>Click here to <a href='login.php'>Login</a></div>";
}
}else{
?>
<div class="form">
<h1>Log In</h1>
<form action="" method="post" name="login">
<input type="text" name="username" placeholder="Username" required />
<input type="password" name="password" placeholder="Password" required />
<input name="submit" type="submit" value="Login" />
</form>
</div>
<?php } ?>
</body>
</html>
My best guess is that $rows returns false hence I am unable to authenticate the user. I have double checked the code, but I can't seem to find any fault in my db connection.
$query = "SELECT * FROM admin WHERE username='".$username."'and password='".md5($password)."'";
$result = mysqli_query($con,$query) or die(mysql_error());
$rows = mysqli_num_rows($result);
if($rows>=1){
$_SESSION['username'] = $username;
// Redirect user to index.php
header("Location: index.php"); exit();
