My website has a PHP login script but the if(isset($_POST['submit'])) doesn't seem to work. It keeps returning with echo "Unable to login. Please contact administrator.";. The code is
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
session_start();
require "dbc.php";
if(isset($_POST['submit']))
{
$username = mysql_real_escape_string($_POST['username']);
$password = mysql_real_escape_string($_POST['password']);
$enc_password = md5($password);
if($username && $password)
{
$query = mysql_query("SELECT * FROM users WHERE username='$username'");
$numrow = mysql_num_rows($query);
if($numrow!=0)
{
while($row = mysql_fetch_assoc($query))
{
$db_username = $row['username'];
$db_password = $row['password'];
}
if($username==$db_username&&$enc_password==$db_password)
{
echo "Logged in <a href='membersarea.php'>Click here to enter the members area</a>";
$_SESSION['username']=$db_username;
header("location: membersarea.php");
}
else
{
echo "Incorrect Username/Password";
}
}
else
{
echo "Incorrect Username/Password";
}
}
else
{
echo "All fields are required";
}
}
else{
echo "Unable to login. Please contact administrator.";
}
?>

I also have one last thing to say, the second script it the one where you type in your login information, when you click 'Login' it directs it to the first one. If you have any questions, please ask me at any time.
