PHP - Login Script Help

Hey ppl

I have a login script that I found in a PHP MySQL book. And yesterday I realized that it is easy to hack this script as it use session variables and it can use cookies.

DOes anyone have login script for me that is secure and easy to implement?

It would really help!

Thanks

Hi all again,

This script was working perfectly but I have not got a clue what changed in it or how and can not seem to find the problem.

The connection works, email and password variables match the mysql databases so must be my Syntax.

appreciate if you can help.

Hello everybody!

I am trying to make a forum for my class and I will do it from scratch I am from Denmark so my english could be a little wrong! Sorry!

The problem is when i try to login, I allways get the error that I had defined to do.. But only if both password and username dosn't exist...
Before i post the code i will give you a translation: Brugernavn = Username kodeord = password brugerid = userid
My register.php file works fine!
But I will post them both:
This is the register form:
http://pastebin.com/h6fgHSFB
And here are the code for my login.php, the strange thing is, that i do not get any kind of error dont even mysql errors, that i had hope on so i could fix it!

I have a login script that isn't rejecting non-users. For whatever reason, it's passing them on to the welcome page where an actual user sees user specific information. I'm newer to php, but can't for the life of me understand why the script doesn't seem to ever utilize the 'else' portion of the 'if' statement. So in short it works as expected for actual users, but non-users are not getting rejected. Below is my code. Any help is appreciated.

Code: [Select]
$sqla = "SELECT count(*) FROM authorize WHERE username='$_POST[username]' and password='$_POST[password]'";
$result = mysql_query($sqla) or die ("Error: ". mysql_error(). " with query ". $query);
$count = mysql_num_rows($result);

if($count==1) {
//start session for user

session_start();

//get company id and user first and last name
$query = mysql_query("SELECT comp_id FROM authorize WHERE username='$_POST[username]'") or die ("Error: ". mysql_error(). " with query ". $query);
$query2 = mysql_query("SELECT firstname, lastname FROM authorize WHERE username='$_POST[username]'") or die ("Error: ". mysql_error(). " with query ". $query);


$resultb = mysql_fetch_assoc($query);
$resultc = mysql_fetch_array($query2);


$_SESSION['coid'] = $resultb['comp_id'];
$_SESSION['firstn'] = $resultc['firstname'];
$_SESSION['lastn'] = $resultc['lastname'];


//get company name
$query3 = mysql_query("SELECT comp_name FROM companies WHERE comp_id='$resultb[comp_id]'") or die ("Error: ". mysql_error(). " with query ". $query);
$resultd = mysql_fetch_assoc($query3);

$_SESSION['conm'] = $resultd['comp_name'];

header("location: overview.php");

} Else {

echo "That user does not exist.";
header("location: login.html");
}

Hi, I am trying to make a login script that uses the user's id from the database, and tries to match it up with the user and password sent by the login form. My checklogin.php page, just jumps back to the index.php page for some reason. I don't know why. I get the following errors, any help greatly appreciated. thank you.


Notice: Undefined index: myusername in /hermes/bosweb/web173/b1739/public_htmlchecklogin.php on line 19

Notice: Undefined index: mypassword in /hermes/bosweb/web173/b1739/public_html/checklogin.php on line 20
Wrong Username or Password

Here is my code to check the id. I can't figure out what is wrong.

Code: [Select]
<?php 

ini_set ("display_errors", "1");
error_reporting(E_ALL);
$host = "";
$database  = "";
$username  = "";
$password  = ""; 
$tbl_name   = "users";
$conn = mysql_connect($host, $username, $password) or die("Could not connect: " . mysql_error());

if($conn)
{
mysql_select_db($database);
} else {
  echo "failed to select database";
}
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT id FROM $tbl_name WHERE username='$myusername' and password= SHA1('$mypassword')";
$result=mysql_query($sql);
$query_data = mysql_fetch_row($result);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result)
;
// If result matched id, table row must be 1 row
if($count==1){
session_start();

     $_SESSION['userid']=$query_data[0];


header("location:login_success.php");
}

else {
echo "Wrong Username or Password";
}

Hey so this is my login script but when i enter something into the username and password box and submit it, the page just refreshes.  

<?php


echo "


<h1>LOGIN</h1>
<form action='' method='POST'>
<table>
<tr>
<td>
<b>Username:</b>
</td>
<td>
<input type='text' name='username' placeholder='Enter your username'>
</td>
</tr>
<tr>
<td>
<b>Password:</b>
</td>
<td>
<input type='password' name='password' placeholder='Enter your password'>
</td>
<td>
<input type='submit' value='login' name='submit'>
</td>
</tr>
</form>
";


$host = "localhost";
$username = "root";
$password = "";
$db_name = "website";


mysql_connect("$host", "$username", "$password") or die("Could not connect");
mysql_select_db("$db_name") or die("Could not find database");


if(isset($_POST['submit'])) {
if(!empty($_POST['username'])) {
$sql = "SELECT * FROM members WHERE username='$username' AND password='$password'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);


if($count==1) {
$row = mysql_fetch_array($sql);
$bancheck = mysql_query($row);
if($row['active']==0 && count==0) {
include 'userban.html';
} else if($count==1 && $bancheck==1) {
$_SESSION['username'] = "$username";
include '/home/user/index.php';
} else {
echo "You entered invalid information";
}
}
}
}


?>

Okay, a few of you have been helping me with a login script problem. I have changed it quite a bit again, but I am still running into a little bit of a problem.

When I click the submit button it just clears the form fields and stays on the login page. Also, I have used error_reporting(E_ALL) to help me out with debugging. I took care of three bugs on my own but I cant seem to clear the two remaining bugs and the fact that it is not forwarding me to any page with my header statement. 

Thanks for your help in advance!

Here is my code from my 'login.php' file.


<?php
session_start();
error_reporting (E_ALL);
include("config.php");
if($_SERVER["REQUEST_METHOD"] == "POST")
{
// username and password sent from form 
$myusername=addslashes($_POST['username']); 
$mypassword=addslashes($_POST['password']); 

$sql="SELECT id FROM admin WHERE username='$myusername' and passcode='$mypassword'";
$result=mysql_query($sql);
$row=mysql_fetch_array($result);
$active=$row['active'];
$count=mysql_num_rows($result);


// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1)
{
session_register("myusername");
$_SESSION['login_user']=$myusername;
header("location: main_interface.php");
}
else 
{
$error="The username or password you entered is invalid, please check your credentials and try again";
}
}
?>
<form action="" method="post">
<label>Username :</label>
<input type="text" name="username"/><br />
<label>Password :</label>
<input type="password" name="password"/><br/>
<input type="submit" value=" Submit "/><br />
</form>


Here are the error messages on the page

Notice: Undefined index: active in login.php on line 20

Warning: Cannot modify header information - headers already sent by (output started at login.php:1) in login.php on line 29



Thanks in advance for your help!

Hello everyone,

I am brand new to php and am starting off my journey by trying to create a simple login/register script.  I have run into a bit of difficulty, however, and cannot seem to get this to work. I know that the register script is very basic (lacks strlen check, doesn't verify that both passwords are the same, etc.), but for the time being I simply want to have a functional script.  Then I can continue learning by adding more components.  Here are the login.php, checklogin.php, and register.php files (in this order).  I believe that the login/checklogin files work, but the register file just shows the form without actually writing to DB when it is submitted.  Thank you very much for your help.

Code: [Select]
<html>
<body>
<b> Member Login </b> <br />
<form name="input" action="checklogin.php" method="post">
Username : <input type="text" name="myusername" id="username"> <br />
Password : <input type="password" name="mypassword" id="password"> <br />
<input type="checkbox" name="remember" value="checkbox"> Remember me <br />
<input type="submit" value="Login">
Not a member? <a href="./register.php">Register!</a>
</form>
</body>
</html>

Code: [Select]
<?php
$host="localhost";
$usr="root";
$pwd="";
$db="MemberDB";
$tbl_name="members";

mysql_connect($host, $usr, $pwd) or die("Unable to connect");
mysql_select_db($db) or die("Unable to select database");

$myusr = $_POST['myusername'];
$mypswd = md5($_POST['mypassword']);

$myusername = stripslashes(strip_tags($myusr));
$mypassword = stripslashes(strip_tags($mypswd));
$myusername = mysql_real_escape_string($myusr);

Hello everyone,

The last few weeks I've asked a few questions. From the answers given, I've finished my login script.
But, I am a noob at oop php and I have also no clue if there are any security holes.

So my question to you guys is:

What have i done wrong? What can i do better? And what's missing?
I also have a one basic question:

I have't declared any variable to public, protected or private. Is it better to declare every variabe? or only a few?
Here is my code:

Index.php:

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST')

{

require('classes/class_lib.php');

if(isset($_POST['username'])){

$username = $_POST['username'];
}
if(isset($_POST['password'])){

$password = $_POST['password'];
}

try{

$user = new User;

$user->login($username, $password);
}
catch(MysqlException $error){

echo $error->getError();
}

catch(LoginException $error){

echo $error->getError();
}

}

?>

// form etc.

And my class_lib.php:

<?php

class MysqlException extends Exception{

public function getError(){

$errorMessage = 'Er is een fout opgetreden in '.$this->getFile().' op regel '.$this->getLine().'<br />';

$errorMessage .= 'Foutmelding: <i>'.$this->getMessage().'</i><br />';

return $errorMessage;

}
}

class LoginException extends Exception{

public function getError(){

$errorMessage = $this->getMessage();

return $errorMessage;

}
}

class Mysql{

public function __construct(){

$this->db = new mysqli('localhost','root','','login');

if($this->db->connect_error){

throw new MysqlException('Kan geen verbinding maken.');

}

}

public function escapeString($string){

$this->string = $this->db->real_escape_string($string);

return $string;

}
}

class Query extends Mysql{

public function runQuery($query){

$this->result = $this->db->query($query);

if(!$this->result){

throw new MysqlException('Er is iets fout gegaan tijdens het uitvoeren van de query.');

}

}

public function returnQuery(){

return $this->result->num_rows;

if(!$this->result){

throw new MysqlException('Er is iets fout gegaan tijdens het ophalen van de resultaten.');

}

}
}

class User{

public function __construct(){

$this->mysql = new Mysql;

$this->query = new Query;

}

public function login($username, $password){

$this->username = $this->mysql->escapeString($username);

$this->password = $this->mysql->escapeString($password);

$this->setQuery = "SELECT gebruikerid FROM gebruikers WHERE gebruikersnaam='" . $this->username . "' AND wachtwoord='" . $this->password . "'";

$this->query->runQuery($this->setQuery);

if($this->query->returnQuery() > 0){

return true;

}else{

if(empty($username) || empty($password)){

throw new LoginException('U moet alle velden invullen.');

}else{

throw new LoginException('Uw logingegevens kloppen niet.');

}

}

}
}

?>

Hi!

where do i download a login script like this used here at phpfreaks

Hello everyone,
I have just finished coding a logion/register/logout script.  I am quite new to PHP (this was my first task to begin the learning process!).  The scripts now work fine and gets the job done.  It incorporates a database and has a number of checks in place.  I know that the code is probably pretty ugly however and not as efficient as it could be.  Could anyone suggest places where I could improve it or security issues with it?  I have tried to secure it against sql injection; it also ensures that no fields are blank and that the two passwords in registration are the same and I have also made username a unique field in database.  Thanks in advance for any help or guidance.

Here are the scripts: index.html, checklogin.php, register.php, menu.php, and logout.php
