ok i have made this login script and it connects to the database and all but it says "Incorrect password!" when i KNOW i put in the correct password, here is the code.

 

login2.php

<?php

$username = $_POST['username'];
$password = md5($_POST['password']);

if ($username)
{

include "connect.php";

$query = mysql_query("SELECT * FROM users WHERE username='$username'");

$numrows = mysql_num_rows($query);

if ($numrows!=0)
{

while ($row = mysql_fetch_assoc($query))
{
		$dbusername = $row['username'];	
		$dbpassword = $row['password'];	
}

// check to see if they match
if ($username==$dbusername&&$password==$dbpassword)
{
	echo "You have sucessfully been logged in! <a href='mem.php'>Click here!</a>";
	$_SESSION['username']=$username;	
}
else
	die("Incorrect password!");

}
else
die("That user Does NOT exist");



}
else
die("Please enter a username and a password!");



?>

while ($row = mysql_fetch_assoc($query))

  {

        $dbusername = $row['username']; 

        $dbpassword = $row['password']; 

  }

 

modify to:

 

list($dbusername, $dbpassword) = mysql_fetch_array($query, MYSQL_NUM);

while ($row = mysql_fetch_assoc($query))

  {

        $dbusername = $row['username']; 

        $dbpassword = $row['password']; 

  }

 

modify to:

 

list($dbusername, $dbpassword) = mysql_fetch_array($query, MYSQL_NUM);

 

Still says "Incorrect password!"

 

and i have even changed my password in the DB to make sure it is the rite password.

After the query check you're getting results.

 

If you are echo the results and compare them to what's being entered into the form.

 

Yes, i am

 

i tried taking out the md5 because in the DB it is not encrypted rite now.

 

still says incorrect password

try this;

 

<?php
session_start();
if(isset($_POST['username']))
{
$username = $_POST['username'];
$password = md5($_POST['password']); //remove md5 if needed
include "connect.php";
$query = mysql_query("SELECT `password` FROM `users` WHERE `username`='$username' LIMIT 1");

$numrows = mysql_num_rows($query);
if ($numrows > 0)
{

	$row = mysql_fetch_assoc($query);
	$dbpassword = $row['password'];

	// check to see if they match
var_dump($password);
echo '<br />should equal<br />';
var_dump($dbpassword);
	if ($password==$dbpassword)
	{
		echo "You have sucessfully been logged in! <a href='mem.php'>Click here!</a>";
		$_SESSION['username']=$username;   
	}
	else
	{
		die("Incorrect password!");
	}

}
else
{
	die("That user Does NOT exist");
}
}
else
{
die("Please enter a username and a password!");
}
?>

try this;

 

<?php
session_start();
if(isset($_POST['username']))
{
$username = $_POST['username'];
$password = md5($_POST['password']); //remove md5 if needed
include "connect.php";
$query = mysql_query("SELECT `password` FROM `users` WHERE `username`='$username' LIMIT 1");

$numrows = mysql_num_rows($query);
if ($numrows > 0)
{

	$row = mysql_fetch_assoc($query);
	$dbpassword = $row['password'];

	// check to see if they match
var_dump($password);
echo '<br />should equal<br />';
var_dump($dbpassword);
	if ($password==$dbpassword)
	{
		echo "You have sucessfully been logged in! <a href='mem.php'>Click here!</a>";
		$_SESSION['username']=$username;   
	}
	else
	{
		die("Incorrect password!");
	}

}
else
{
	die("That user Does NOT exist");
}
}
else
{
die("Please enter a username and a password!");
}
?>
