PHP - Php Login System Fetch Username And Redirect Issue

Hi guys, <----- new to this forum and coding for that matter!

I have a question. I have been asking around and reading up about how to make a forum with my current tools (dreamweaver/mysql/mysqlyog) for my website, and 90% of the time the answer i get is "if your asking the question, dont bother..... use mybb or some other premade forum" Which is fine, i dont mind! But know i have an issue. To get access to my website you are requierd to login before you can do anything, after login your able to use the whole site. But now if i use one of these ready made forums such as mybb or whatever users are required to make ANOTHER registration and login aswell! and me no likes this!

So my question is, is there a way to make it so the forum runs off the same login used for my website?

TIA

Hello

Im making a secure php login system and ideally wanted to also md5 hash the username as well as the password. My reasons for doing this is to completey stop sql injections as i can combine the md5 hash with salt for the $_POST['username'].

Now my problem is i need to be able to de-hash (if this is a word) the username for admin purposes of the business. For password reset i will just send a new password.

Is there anyway that i can do this easily whilst keeping my username secure and stop sql injection for username?

I want to limit the number of incorrect login attempts within a specified time period (e.g. 15 minutes). I'm wondering what I should tie those attempts to.

e.g. If too many attempts from one ip address for a specific username, lock them out for 15 minutes? Or too many attempts from any ip address for a specific username? Or too many attempts for an ip address matched loosely (i.e. 255.255.255.0 matching) with a specific username?

What's the best choice? Just too many attempts for a username? Or also use the ip address?

And should I store the attempts in the session, or the DB?

Hi all,  I have been reading in almost everywhere that we should not use our own custom login and password validations ( like regex etc.) but instead use the filter_var and filter_input built in functions provided by PHP 5 and above. However even after searching for more than an hour for with different search strings, I have not found even a single example that shows how we may validate for a username/login and password in a login form. Can someone be kind enough to provide a strong secure validations for username and login. Additionally I would also like to clarify if the username and login fields in a Login form be manipulated in any manner to pose a security threat? I mean can a hacker craft a username/login or password in such a manner as to pose an injection or any other threat? Thanks all.

Hello all;
I have a client that has a members area.  He asked me to password protect it, which I did simply by assigning one static password.  Now he wants a full username/login system where the member can set their own password, which I have never done before.  I assume I'd just set up a Table with three fields, (one for name, one for password, one for the type of access they have) then check against it for access, but experience has taught me that whenever something seems simple, it's actually very complex. 

Do any of you know of any good premade templates for this kind of thing?  Ideally it'd be session-based (obviously).  I found one system he http://frozenade.wordpress.com/2007/11/24/how-to-create-login-page-in-php-and-mysql-with-session/  but it's several years old, and the misspellings in the comments tend to scare me away a bit. 

Thanks for any help you might be able to provide.

Alright, I've been assigned a project at work. I did not develop the application and the individual who did used CodeIgnited framework and mysql as the db.   Here's the problem, I'm not given much OT to do this and in our meeting the best way to proceed was to replicate the database for different parts of the organization. Basically we are a subsidiary and have been using an application that other groups within the organization want to use. Usually I would reconfigure the db schema and add org ids and in the user table add the appropriate organization to go to. However, they are not giving me enough time to do that.   So what I'm thinking is to just create a copy of the database we use (just the structure) and create a new database.   What I want to know is how to use mysql to check to see if a user exists in one database and if they don't then to go on to the next database. I understand this is a very sloppy way to do it, but it's the way we are moving forward.   I found the code to connect to the db in CodeIgnitor... how can I connect to a database, check to see if the user exists, then close that db connection and try the next database?  

    /**
     * Select the database
     *
     * @access    private called by the base class
     * @return    resource
     */
    function db_select()
    {
        return @mysql_select_db($this->database, $this->conn_id);
    }

  Thanks in advance.

So basically my project is one where the user can log onto my website, and the page then checks if the ID and password are in my table in my microsoft access file.

If the username and password are the same, the user continues, if it isnt, then it stays on the same page and says something like "username and/or password are incorrect" or something along the lines of that.

the problem is right now im not sure how to make it say  "ERROR username and/or password is incorrect" if the username and password dont match. Can someone help me with this? and also make sure if the username and password are correct that it goes to the next page, entitled searchpage.php

here is the code Code: [Select]
<html>
<head>
<style type="text/css">



</style>
</head>
<body style="text-align:center">

<div id='title'>

</div>

<?php

print_r ($_POST) ;

if 

if (isset($_POST['Login'])) { 


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



$username  = null ;
$password  = null ;
 
$connection = odbc_connect('Olympics', '', '');
 
 
 if (!$connection)
{exit("Conection Failed: " . $connection);}


$username = stripslashes($username);
$password = stripslashes($password);

$sql = "select * from users where users = '$username' and passwords = '$password'";

$rs=odbc_exec($connection,$sql); 



$count=odbc_num_rows($rs);
 
if ($count == 1) {
     $_SESSION['loggedIn'] = "true";
     header("Location: searchpage.php");
} else {
     $_SESSION['loggedIn'] = "false";
    header("Location: index.php"); 
echo "Login failed" ;
}
 


}

echo "<form action='index.php' method='post'> \n" ;
echo" Please enter your username and password if you wish. <br/> \n" ;
echo "Username: <input type='text' name='username' > \n " ;
echo "Password: <input type='password' name='password' > \n" ;
echo "<input type='submit' value='Login' name='Login'> <br/> \n" ;
echo "<input type='submit' value='You may also continue you as a guest.'> \n" ;
echo "</form>" ;

Hi All

I am using the following method to check if user is logged in to a member area. However, I ahve a password change section that then redirects back the the password change page within the logged in area. After password changes it automatically redirects back to the index page rather than password page and comes up with a redirect error (too many redirects)

How can i change the code to match the new change in password. I think its a sessions problem but not great with sessions!
Code: [Select]
if(isset($_COOKIE['ID_my_site']))
{
    $username = $_COOKIE['ID_my_site'];
    $pass = $_COOKIE['Key_my_site'];
    $check = mysql_query("SELECT * FROM member_users WHERE email = '$username'")or die(mysql_error());
    while($info = mysql_fetch_array( $check ))
    {
$usernameid=$info['username'];
$userid = $info['id'];
$firstname = $info['fname'];
$lastname = $info['lname'];
        //if the cookie has the wrong password, they are taken to the login page
        if ($pass != $info['password'])
        {
            header("Location: index.php");
        }
        //otherwise they are shown the admin area
        else
        {
            echo "<div class=\"memberloginactive\">Welcome $firstname | Your Profile | <a href=\"edit-profile.php?id=$userid\">Edit Profile</a> | <a href=\"logout.php\">Logout</a></div><div class=\"clear\"></div>";
        }
    }
}
else

First of all hello as I am new to this forum.

Ok so, I am have been trying for the past few days to create a login system in PHP for a website I am creating, and I am having serious problems. I have tryed so many tutorials and they all are not working, my conclusion is they are outdated or not fully understandable.

So what I want to create -
Registration
Forgot password
Login page
Email activation
Member page

My hosting has the latest php and mysql as far as I know so could someone please give me an up to date simple tutorial on creating this.

Lastly the program I am using is Dreamweaver CS5

Thankyou.

I've abandoned my old script and switched to this one: http://www.evolt.org/node/60384

I got it working on my site just fine (djsmiley.net/members/register - you can test it out if u want). i just want to know how i can put all of the code into the pages i created using my template.

It doesn't specify how this can be done in the tutorial, which is why im confused. I've tried everything but keep getting errors. Help?

I'm trying to build a login system and alot of the code is similar to what i used to make my news cms. basically all i wanna accomplish right now is to get the user input inserted into my database. I've already tested it out, and I get no errors, but like with the cms, the database isn't getting queryed.

Here's the code:
(process.php)
Code: [Select]
<?php
 $first_name=$_POST['first_name']; 
 $last_name=$_POST['last_name']; 
 $age=$_POST['age']; 
 $city=$_POST['city']; 
 $state=$_POST['state']; 
 $country=$_POST['country']; 
 $zip=$_POST['zip']; 
 $birthdate=$_POST['birthdate']; 
 $gender=$_POST['gender']; 
 $sexuality=$_POST['sexuality']; 
 $race=$_POST['race']; 
 $religion=$_POST['religion']; 
 $status=$_POST['status']; 
 $about=$_POST['about']; 
 $website=$_POST['website']; 
 $user_name=$_POST['user_name']; 
 $password=$_POST['password']; 
 $email=$_POST['email']; 
 mysql_connect("your hostname", "your database name", "your password") or die(mysql_error()); 
 mysql_select_db("your database name") or die(mysql_error()); 
 
 $sql = sprintf("INSERT INTO Users (first_name, last_name, age, city, state, country, zip, birthdate, gender, sexuality, race, religion, status, about, website, user_name, password, email)
VALUES ('%s', '%s', '%s', '%s', '%s')",

mysql_real_escape_string($last_name),
mysql_real_escape_string($age),
