I have been trying to use mysqli_query to connect to database define in an external file but am getting an repeated error as undefined $conn
index.php
<?php
require 'connect.in.php';
include 'loginform.php';
?>
connect.in.php
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbase = "users";
$conn = mysqli_connect($servername,$username,$password);
if($conn ||!mysqli_select_db($dbase)){
die('error message');
}
?>
loginform.php
<?php
if(isset($_POST['username']) && isset($_POST['password'])){
$username = 'username';
$password = 'password';
if(!empty($username) && !empty($password)){
$query = "SELECT 'id' FROM 'user_list' WHERE 'username'= '$username' AND 'password' = '$password'";
if(mysqli_query($conn, $query)){
echo "correct";
}
else{
echo "false";
}
}
}
?>
<form method="post">
Username:<input type="text" name="username">
Password:<input type="password" name="password">
<input type="submit" value="Login">
</form>
also is it possible to incorporate CSS and Bootstrap in this php files say for loginform.php?
