PHP - Login System

Hi guys.

What I want to create is really complicated. Well I have a login system that works with post on an external website.
I have my own website, but they do not give me access to the database for security reasons, therefore I have to use their login system to verify my users.
What their website does is that it has a post, with username and password. The POST website is lets say "https://www.example.com/login".
 If login is achieved (i.e. username and password are correct), it will redirect me to "https://www.example.com/login/success" else it will redirect me to "https://www.example.com/login/retry".

So I want a PHP script that will do that post, and then according to the redirected website address it will return me TRUE for success, FALSE for not successful login.

Any idea??

Thanks

Hi All!   This is my first post here, so if there are some things I miss or something more I need to do please let me know.   I tried searching the forum for the answer first but could not find anything.   So here is the thing; I followed a tutorial I found about building a login system for my website. The tutorial worked perfectly, except I needed it to redirect to a user specific page instead of a static page on login. I made the necessary changes to the script, and now it redirects to the user specific page, but does not recognize that I am logged in so it will not show me the content.   In the interest of full disclosure, I am not very good at PHP and lack a fundamental understanding of it. I am enrolled in some Udemy courses to try to rectify that, but I needed the login system ASAP, so copy and paste programming was my only option. I know, I know. I am a terrible human being and should be thrown into the sun. I agree. I am in counseling to try to deal with it.   The tutorial I used can be found he  http://www.wikihow.c...n-PHP-and-MySQL.   Here is the relevant code:   process_login.php:  

<?php


include_once 'db_connect.php';
include_once 'functions.php';


sec_session_start(); // Our custom secure way of starting a PHP session.


if (isset($_POST['email'], $_POST['p'])) {
    $email = $_POST['email'];
    $password = $_POST['p']; // The hashed password.


$page = login($email, $password, $mysqli);
if ($page == true) {
  // Login success        
  header('Location: '. $page);
   exit();


    } else {
        // Login failed 
        header('Location: ../error.php?error=1');
    }
} else {
    // The correct POST variables were not sent to this page. 
    echo 'Invalid Request';
}

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()); 
 
 $sql = sprintf("INSERT INTO Users (first_name, last_name, age, city, state, country, zip, birthdate, gender, sexuality, race, religion, status, about, website, user_name, password, email)
VALUES ('%s', '%s', '%s', '%s', '%s')",
mysql_real_escape_string($first_name),
mysql_real_escape_string($last_name),
mysql_real_escape_string($age),
mysql_real_escape_string($city),
mysql_real_escape_string($state),
mysql_real_escape_string($country),
mysql_real_escape_string($zip),
mysql_real_escape_string($birthdate),
mysql_real_escape_string($gender),
mysql_real_escape_string($sexuality),
mysql_real_escape_string($race),
mysql_real_escape_string($religion),
mysql_real_escape_string($status),
mysql_real_escape_string($about),
mysql_real_escape_string($website),
mysql_real_escape_string($user_name),
mysql_real_escape_string($password),
mysql_real_escape_string($email));
$result = mysql_query($sql);

Hi Everyone,

Just a quick question before I take on this project.

Basically the client has a secure server set up with folders for different clients. So they can store excel files, PDFs etc, What the client use to do was send the client an email with the http address of that clients particular folder to be able to login.

What my job is to create a login system that redirects each client to their particular area on the secure system.

Is this going to be difficult,

What I was thinking of doing was when the administator is setting up the client details there would be an extra field saying address: they paste the address of the folder on the server. Then it will redirect them to their folder.

Is this the correct way to do this.

Any help or advice would be great.
