Hi Freaks, I'm looking for advice if someones willing to give it. Here's the situation -> I've been working on a project, I started to learn PHP specifically to complete this idea I had. My code has evolved a lot over time as I've started understanding more. Up until today I've been working on it with just the registration functionality, no login. I had my username hardcoded into the $user_obj instantiation. I decided I wanted to try to make category subscription functionality and doing that I realized I was better off finishing the login form first so as to get a users subscriptions into a session variable at login. This has brought about the issue of getting an unassigned variable warning from the User class when not logged in. How I made all my other classes was putting a $user in the __construct parameter for each class. I now feel this may have been a rookie error since I'm having problems with error messages especially undefined array keys and variables when there isn't a session started. It's become a bit of a mess. So the advice I'm looking for and hoping to find here is how you folks handle non $_SESSION sessions, when a user is just scrolling the site not logged in. Did I make a mistake requiring $user for each class __construct? should I move the $user parameter to only the methods that require them? Is there a simpler solution that my inexperience causes to elude me? What would you folks do in this situation?

i want to display 'Welcome userid!' after user has successfully logged in. I managed to display it after successfully logged in, but when the user key in the wrong userid and password, the 'Welcome userid' is also displayed. What should i do about it? Below are my coding: login.html processLogin.php index.html

Hello there, I have this as login in function for an application. function login($username, $password) { $db =& $this->db; Kit::ClassLoader('userdata'); if (Config::Version('DBVersion') < 62) { // We can't do CSPRNG because the field doesn't exist, so we need to do standard user login // This can ONLY happen during an upgrade. $dbh = PDOConnect::init(); $sth = $dbh->prepare('SELECT UserID, UserName, UserPassword, UserTypeID FROM `user` WHERE UserName = :userName'); $sth->execute(array('userName' => $username)); $rows = $sth->fetchAll(); if (count($rows) != 1) { setMessage(__('Username or Password incorrect')); return false; } $userInfo = $rows[0]; // Check the password using a MD5 if ($userInfo['UserPassword'] != md5($password)) { setMessage(__('Username or Password incorrect')); return false; } } else { // Get the SALT for this username if (!$userInfo = $db->GetSingleRow(sprintf("SELECT UserID, UserName, UserPassword, UserTypeID, CSPRNG FROM `user` WHERE UserName = '%s'", $db->escape_string($username)))) { setMessage(__('Username or Password incorrect')); return false; } // User Data Object to check the password $userData = new Userdata($db); // Is SALT empty if ($userInfo['CSPRNG'] == 0) { // Check the password using a MD5 if ($userInfo['UserPassword'] != md5($password)) { setMessage(__('Username or Password incorrect')); return false; } // Now that we are validated, generate a new SALT and set the users password. $userData->ChangePassword(Kit::ValidateParam($userInfo['UserID'], _INT), null, $password, $password, true /* Force Change */); } else { // Check the users password using the random SALTED password if ($userData->validate_password($password, $userInfo['UserPassword']) === false) { setMessage(__('Username or Password incorrect')); return false; } } } // there is a result so we store the userID in the session variable $_SESSION['userid'] = Kit::ValidateParam($userInfo['UserID'], _INT); $_SESSION['username'] = Kit::ValidateParam($userInfo['UserName'], _USERNAME); $_SESSION['usertype'] = Kit::ValidateParam($userInfo['UserTypeID'], _INT); // Set the User Object $this->usertypeid = $_SESSION['usertype']; $this->userid = $_SESSION['userid']; // update the db // write out to the db that the logged in user has accessed the page $SQL = sprintf("UPDATE user SET lastaccessed = '" . date("Y-m-d H:i:s") .

My sign in code called activation is the script called activation.php. my login page is login.php and my profile page is the landing page once a successful login in attempt is made. the activation.php is the issue as i us the form in sign.php to login but the activation.php doesn't redirect me to the sign in page once a fail attempt is made or it doesn't redirect me to my profile page once a successful login in attempt is made. The following link has the code:https://gist.github.com/confusedstudent21/410f04991691f485e6c28d1e4050e13a where is it going wrong?

I am using this https://github.com/ircmaxell/password_compat I have no problem using it on a local server. But as soon as I test it on a live server, it gives me an error like this. Parse error: syntax error, unexpected '{' in /home/public_html/sub/snippets/password.php on line 19 The error is on the same line as the beginning of the code in that library. Why is this happening?

I have been working on a login form, I have completed the registration side but the login form is proving to be fighting back. I have just jumped into the world of PDO and only recently PHP in a serious way. I have been trying to use the password_verify(); function but I have spent so long on it now trying to get it working I have made it more difficult than it should be and probably is. I would be grateful if someone could take a look at my code and just tell me what I am doing wrong. I have tested it with the username and password hard coded in and it returns an array however if I comment out the hard coded username and password I get an empty array. I dare say that someone will see the issue straight away but I cannot get my head round it. <?php session_start(); error_reporting(0); require '../php_inc/connection/connect.php'; require_once '../php_inc/functions.php'; $error = ''; // all error messages will use this variable $msg = 'Please fill in both fields and answer the captcha, they are all required to log in.'; if(isset($_POST['submitted'])){ $dbuname = 'dashby'; // As if check with DB - If I comment these 2 out and try to get data from DB I get empty array $hashed = '$2y$12$7hcyfm7UjboYGaNLF7vK1.qroo3YkvhKAR8EfxG1byEMkNB0oSQgi'; // As if check with DB - same password require 'Captcha.php'; $username = escape_in($_POST['username']); // Username $captcha = escape_in($_POST['captchaResult']); //Captcha $unhashed = escape_in($_POST['password']); //Password b4 hashing takes place //$submittedPassword = password_hash($unhashed, PASSWORD_DEFAULT, ['cost' => 12]); // connect to the database so the checks can be done. if($pdo){ $stmt = $pdo->prepare("select * from users where username = :username && password = :password"); $stmt->bindParam(":username", $username); $stmt->bindParam(":password", $unhashed); // If $hashed is the variable I get an array returned, as $unhashed I get an empty array echo '<pre>'; if($stmt->execute()){ $rows = $stmt->fetchAll(PDO::FETCH_ASSOC); print_r($rows); } } echo '</pre>'; if($total == $getCaptchaResults){ //Capcha OK if(password_verify($unhashed, $hashed)){ //$msg = ''; //$error .= 'Password match'; if($username == $dbuname){ //$msg = ''; //$error .= 'Captcha, username and password ok'; // working to this point $_SESSION['username']; //header('Location: welcomelogged.php'); } else { $msg = ''; $error .= 'Denied wrong username and/or password'; } } else { $msg = ''; $error .= 'Denied wrong password and/or username'; } } else { if(($total != $getCaptchaResults)){ $msg = ''; $error .= 'Captcha Wrong'; } } }// post submitted brace ?> The if statements all work bar the password_verify when I comment out the hard coded variables out, directly under if(isset($_POST['submitted'])) {} I would be grateful if someone could steer me in the right direction. Thanks in advance.

So i made a login page, but whenever i enter right, wrong, or no password at all, it always displays wrong password. I've been trying to fix it for hours, but I just can't seem to find the error. It's like it's skipping if the password is right statement and goes straight through the else statment. <?php $connection = mysql_connect("com-db-02.student-cit.local","***","***") or die (mysql_error()); if ($connection) echo "Connection successful"; else echo "Connection failed"; $db = mysql_select_db("TEAM20") or die (mysql_error()); ?> <?php $_SESSION['customeremail'] = $_POST['user']; $_SESSION['password'] = $_POST['password']; function signIn() { session_start(); if(!empty($_POST['user'])) { $query = mysql_query("SELECT * FROM customer where customeremail = '$_POST[user]' AND password = '$_POST[password]'"); $row = mysql_fetch_array($query); if(!empty($row['customeremail']) AND !empty($row['password'])) { $_SESSION['customeremail'] = $row['customeremail']; getCustDetails(); echo "Successfully login to user profile page.."; echo "<a href=userlogin.php>Profile</a>"; } else { echo "Sorry... YOU ENTERED WRONG ID AND PASSWORD"; echo "<a href=login.html>Try Again</a>"; } } } function getCustDetails() { $queryId = mysql_query("SELECT customerID, firstname FROM Customer WHERE customeremail = '$_POST[user]'"); while($rowId = mysql_fetch_array($queryId)) { $_SESSION['customerID'] = $rowId['customerID']; $_SESSION['firstname'] = $rowId['firstname']; } echo "Code: ".$_SESSION['customerID']; echo "Name: ".$_SESSION['firstname']; } if(isset($_POST['submit'])) { signIn(); } ?>

Hi everyone I am building a CRM system/invoicing system in my spare time and on this system I have 2 login pages (there is a reason but its long). one for the CRM system and one for the invoicing section. They bother work perfectly well but I have a really annoying issue, If I were to store the login information to chrome passwords for example to the CRM system It would auto suggest to the other login and vice versa. This wouldn't be a problem but the CRM login is username based, the invoicing section is login by email for additional security. they're both called login.php the two files are /htdocs/login.php and /htdocs/invoicing/login.php I added a remember me cookie to the CRM system in hope that this would get around the issue but unfortunately the chrome saved information over rides this, I also tried autocomplete="off" as I am using bootstrap as a framework. How can I get around this?

Hi, The 'admin' section of my website stopped working a couple of months ago and I'm just trying to fix it - I was getting an error about Session_Register being deprecated and I'm now trying to knife and fork my way around it with results from various google searches. I'm an advanced SQL user but only occasionally dabble with PHP so any help would be appreciated. So, basic set up, login page checks credentials against the DB, a session cookie is set and you're let into the admin area - my script is looping me back to the login page as my !isset is true.....because I can't figure out how to set it with the new functions! This is the login include..... <?php $host="database.lcn.com"; // Host name $username="blahblah"; // Mysql username $password="blahblah"; // Mysql password $db_name="blahblah_db"; // Database name $tbl_name="users"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // username and password sent from form $myusername=$_POST['username']; $mypassword= md5($_POST['pass']); // 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); $sql="SELECT * FROM users WHERE is_obv = '1' and username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" $_SESSION['username'] = $myusername; $_SESSION['pass'] = $mypassword; header("location:../admin"); } else { header("location:http://www.web.co.uk/ooops"); } ?> and this is the 'login_success' include that I include on each protected page.... <? session_start(); if(!isset($_SESSION['username'])){ header("location:http://www.web.co.uk/login"); } ?> Darren

Hi Everyone So I've been recently working on a script which will store login IP's and ban them on failed attempts Although I have a little problem, for some reason it doesnt redirect to the banned page when they should be, unless there is a successful login or if they come off of the login page so they can keep bruteforcing as much as they like all the time they stay on that page.

I am testing to see if PHP variables can pass from previous page to present page to login, I notice it doesn't work in MySQL query from previous to present page. It is like using ID to pass the variable in link like this: "?id=" in link, but I am using submit button. I typed name="user" in previous page, that should pass variable to present, then set up the select in database, but it doesn't do that, what i did do wrong? if ($_POST['submitted']) { $username = $_POST['user']; $password = $_POST['pass']; if ($username && $password) { $log = "SELECT username, password, type FROM username WHERE username = '".$username."' AND WHERE password = '".$password."'"; $result = mysqli_query($Garydb, $log) or die("could not work"); echo "<p>".$result['username']."</p>"; } } Also, I wonder about two query in one sentence, like using 'AND' on sentence, will it works? Please advise me. Thank you in advance time. Gary P.S. how do you type in chart like notepad++ in here? I need to know how to do that, so I show you in number line that you can point much easier to read.

Hi everyone, Anyone recommended me to learn how to set up the login system, it is most advanced system, even longer work. Anyone know link to website that can help me learning about login system? Video will be very appreciate... Thanks, Gary

Hi, Just wondering if someone could point me in the right direction, I have a simple PHP MySQL login script which passes/stores data via sessions. It works fine, there is no problem with it. All I would like to do is pass some additional data from the users MySQL table. Currently it users just username and password, but I would like it to pass firstname and surname data as well. So when a user logs in with their username and password, on the next page it might say Welcome, Michael Smith. The script below is originally setup for the username to be a persons name, as it's used in the login welcome message in the login.php But I might change the username to be an email address, if I can pull in the additional data. config.php <?php /***************************** File: includes/config.php Written by: Frost of Slunked.com Tutorial: User Registration and Login System ******************************/ // start the session before any output. session_start(); // Set the folder for our includes $sFolder = '/predictor/login'; /*************** Database Connection You will need to change the user (user) and password (password) to what your database information uses.

Unfortunately my ideas out pace my skills. I have a database that I would like certain people to access their own info, but nobody else's. It's not super sensitive info and won't mean much to anyone other than the end user but we don't like the idea of others accessing it so we'd like to put some protection on it. What I was hoping for is a dropdown list (there's about 30 or so clients that would be in a mysql table) where they can pick out their name, then text box for the password. When they hit submit button it would lead them to their own page with a table and their own info from a mysql table. I can get each one of these details to work separately, but I'm having trouble putting them all together (the password is where things get muddled). Can anyone point me to a place where they've already figured this out? Thanks!

Hi, I've been going out of my mid for almost a week now trying to figure out how to make this work... I want multiple users to have their own individual usernames and passwords and be able to log in and view certain pages that non-registered guests can't see. I've set up my databases and usernames and passwords. I've actually gotten my login code to work now and then, but in trying to get sessions to work and not allow just anyone to manually type in the addresses of certain pages I've managed to mess that up and it doesn't work now either. I've been to MANY different sites and used examples but just can't get the login to work properly nor figure out how to get the sessions to check for a logged in user. My code so far...I've taken out my real password login,php <?php $connection = mysql_connect('localhost', 'root', 'mypassword'); if (!$connection){ die("Database Connection Failed" . mysql_error()); } $select_db = mysql_select_db('login'); if (!$select_db){ die("Database Selection Failed" . mysql_error()); } if (isset($_POST['username']) and isset($_POST['password'])){ $username = $_POST['username']; $password = $_POST['password']; $username = stripslashes($username); $password = stripslashes($password); $username = mysql_real_escape_string($username); $password = mysql_real_escape_string($password); $query = mysql_query("select * from members where password='$password' AND username='$username'", $connection); $result=mysql_query($sql); $count=mysql_num_rows($result); if($count==1){ session_register("username"); session_register("password"); $_SESSION["authorized"] = true; header("location:membersarea.php"); } else header ("Location: login.html"); } ?> And this is what I put at the top of each secured page... membersarea.php <?php session_start(); if ($_SESSION["authorized"] = true) { } else { header("Location: login.html"); } ?> Thanks in advance!

Hi, wish somebody can help me T_T I'm little bit confused how to make user log-in based on country or territory, what I'm talking about is like this: The User table is: id_user | username | password | level | id_country The Country table is: id | country_name And when user login, there's a data entry form and there is a drop-down/combo-box in a form, that filled with user countries, like this: Country: [____] --> This part is automatically filled/disabled field if a user log-in with their username based on level and countries. Province: [____] --> This is a chained combo-box from countries City: [____] --> Also this chained to Province What I mean is, when user's log-in with their country id, so the "Country Combo-Box" will be automatically filled and disabled. So user can't choose another country, only their country based on username and territories. Thank you for all your help.

I am trying to create a remote login to one website using mine. The users will need to enter their username and password on my site, and if they are registered to my website, their login credentials will be sent to another website and a page will be retrieved.

Hi, I am trying to create a login system in PHP, but I am not the greatest at PHP so I am using a source code which I found online as I found it to be more secure as it uses things like salted passwords. Anyway I am trying to add more fields to the register system so it adds them to the mysql, the source has a way to do this with arrays, but it is quite complicated so I am just using variables from the original file. There are 2 files: register.php and class.loginsys.php which contains all the functions. At first the query syntax was incorrect so I decided to use the variables created in register.php in the class.loginsys, but now it's giving me an out of memory error: Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 28672 bytes) in C:\xampp\htdocs\ls\class.loginsys.php on line 34 Which I am unsure of how to fix. I have tried using different variable names, checking the line, checking the whole register.php file for anything rogue. Here is the code: Top part of register.php <?php include "config.php"; ?> Config.php: <?php require "class.loginsys.php"; $LS=new LoginSystem(); ?> Then actual register part from register.php: <?php if( isset($_POST['submit']) ){ $firstname2 = $_POST['firstname']; $lastname2 = $_POST['lastname']; $user2 = $_POST['username']; $sex2 = $_POST['sex']; $country2 = $_POST['strCountryChoice']; $email2 = $_POST['email']; $pass2 = $_POST['pass']; $pass3 = $_POST['pass2']; $birthdate2 = $_POST['birthdate']; $created2 = date("Y-m-d H:i:s"); //need to add a lot more validation functions.. AKA Check if email exists and username. Password > 5 chars if( $user2=="" || $email2=="" || $pass2=='' || $pass3=='' || $firstname2=='' || $lastname2=='' || $sex2=='' || $country2=='' || $birthdate2=='' ){ echo "Fields Left Blank","Some Fields were left blank. Please fill up all fields."; exit; } if( !$LS->validEmail($email2) ){ echo "E-Mail Is Not Valid", "The E-Mail you gave is not valid"; exit; } if( !ctype_alnum($user2) ){ echo "Invalid Username", "The Username is not valid. Only ALPHANUMERIC characters are allowed and shouldn't exceed 10 characters."; exit; } if($pass2 != $pass3){ echo "Passwords Don't Match","The Passwords you entered didn't match"; exit; } $createAccount2 = $LS->register($user2, $pass2, array( "email" => $email2, "name" => $firstname2, "lastname" => $lastname2, "gender" => $sex2, "country" => $country2, "DOB" => $birthdate2, "created" => date("Y-m-d H:i:s") // Just for testing ) ); //$createAccount = $LS->register($firstname,$lastname,$user,$sex,$country,$email,$pass,$birthdate,$created); if($createAccount2 === "exists"){ echo "User Exists."; }elseif($createAccount2 === true){ echo "Success.

I am doing this because for a hobby I am trying to create a browser based game in which I use this login system to login the user to a main page then code all of the other pages myself. I have posted on stackoverflow and someone on their suggested that I should use a framework. If this is the case, can someone point me in the right direction? Thanks again, if you need any info ask.

Hi experts,I have the following problem.I have a file login.php which is used to allow users to log in.When the form is submitted it is redirected to checkuserlogin.php.If the credentials are right he is redirected to main.php.But in main.php if the user clicks back browser button,he is redirected to login.php and in login.php if he presses forward button,he is redirected to main.php.Can any one tell he how to make sure the application is not redirected to main.php when user presses forward button and how to make sure the application is not redirected to login.php when user presses back button.
