code for sql connection:
<?php
define('DB_SERVER','localhost');
define('DB_USER','root');
define('DB_PASS' ,'');
define('DB_NAME', 'shopping');
$con = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME);
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
code for login:
<?php
session_start();
error_reporting(0);
include("include/config.php");
if(isset($_POST['submit']))
{
$username=$_POST['username'];
$password=md5($_POST['password']);
$ret=mysqli_query($con,"SELECT * FROM admin WHERE username='$username' and password='$password'");
$num=mysqli_fetch_array($ret);
if($num>0)
{
$extra="change-password.php";//
$_SESSION['alogin']=$_POST['username'];
$_SESSION['id']=$num['id'];
$host=$_SERVER['HTTP_HOST'];
$uri=rtrim(dirname($_SERVER['PHP_SELF']),'/\\');
header("location:http://$host$uri/$extra");
exit();
}
else
{
$_SESSION['errmsg']="Invalid username or password";
$extra="index.php";
$host = $_SERVER['HTTP_HOST'];
$uri = rtrim(dirname($_SERVER['PHP_SELF']),'/\\');
header("location:http://$host$uri/$extra");
exit();
}
}
?>
It gives invalid username and password error all time even username and password are correct. Connection with mysql server done and work properly but issue with login as admin in admin penal.
