am working with login form but it doesn't work, when am trying to var_dump my sql
<?php
session_start();
include ('database.php');
if (isset($_POST['login'])) {
$user = $_POST['username'];
$pass = sha1($_POST['pass']);
$sql = "SELECT * FROM users WHERE pass = sha1('$pass')
AND username = '$user'";
$query = mysqli_query($conn,$sql);
$results = mysqli_num_rows($query);
//die(var_dump($results));
if ($results == 1) {
$_SESSION['username']=$user;
}
header('location: index.php');
}
?>
So I am trying to create a simple login structure, and im not sure why it does not work, I appreciate there are many examples on here, and please do not mark this for duplication, I just really need some help I have tried and tried but I can not see what I have done wrong.
<?php
session_start();
include 'databaseconnection.php';
$email = strip_tags($_POST['email']);
$pwd = strip_tags($_POST['pwd']);
$sql = "SELECT * FROM user WHERE email='$email'";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);
$hash_pwd = $row['pwd'];
$hash = password_verify($pwd, $hash_pwd);
if ($hash == 0) {
header("Location: error.php")
exit();
} else {
$sql = "SELECT * FROM user WHERE email='$uid' AND pwd ='$hash_pwd'";
$result = mysqli_query($conn, $sql);
if (!row = mysqli_fetch_assoc($result)); {
echo "your email address or password is incorrect!";
} else {
$_SESSION['id'] = $row['id'];
}
header("Location: profile.php")
If someone could simply suggest what changes I should make, I would really appreciate it.
There you go simple code
<?php
session_start();
include 'databaseconnection.php';
$email = $_POST['email'];
$pwd = $_POST['pwd'];
$sql = "SELECT * FROM user WHERE email = '$email'";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);
$hash_pwd = $row['pwd']; // password from database
// if password is valid start session and redirect to profile.php
if (password_verify($pwd, $hash_pwd))
{
$_SESSION['id'] = $row['id'];
header('Location: profile.php');
}
else
{
header("Location: error.php")
exit();
}
?>
You have not closed the "} else {"... section.
First check request second filter input third use pdo
<?php
session_start();
include 'databaseconnection.php';
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
$email = filter_input(INPUT_POST, 'email',FILTER_VALIDATE_EMAILL); //filter input
$pwd = filter_input(INPUT_POST, 'pwd',FILTER_SANITIZE_STRING,FILTER_FLAG_STRIP_HIGH); //filter input
$hashed = sha1($pwd);
$sql= $conn->prepare( "SELECT * FROM user WHERE email ? AND password = ?"); //use pdo here
$sql->execute(array($email, $pwd));
$row = $sql->fetch();
if($row['email'] !== $email || $row['password'] !== $hashed){
header("Location: error.php");
exit();
} else {
$_SESSION['id'] = $row['id'];
header("Location: profile.php");
}
}else {
echo 'error';
}
?>
I have realized why i can't actually access userdata (after i am logged) old way to find the username is $_SESSION['username']; (assuming there is a row as 'username' in MySQL database)
So as i have a test account as "good25" (reason to choose numbers was to see if Alphanumeric inputs works fine.. its just checkup by me.. nevermind)
Problem :
assuming, i have rows in a table as 'username' and all of his information.. such as 'password', 'email', 'joindate', 'type' ...
On net i found out how to snatch out username from Session
<?php session_start(); $_SESSION('username'); ?>
successful!!
i had an idea to check if session is actually registering or no??
after a log on start.php i used this code
if(isset($_SESSION['username'])) { print_r($_SESSION['username']); }
the result was "1" (while i logged in using this username "good25")
any suggestions?

I am not asking you to build a script.. just little help please? (Thank you so so so so so much, as i am a self-learner, you don't have to say everything.. just a clue is enough for me)
may be you can try this code
<?php
require_once 'require.inc.php';
//session_start();
if (isset($_POST['btn-login']))
{
$uname = mysqli_real_escape_string($_POST['uname']);
$upass = mysqli_real_escape_string($_POST['upass']);
$search = mysqli_query($connection, "SELECT username, userid, password from $user_table WHERE username='$uname' AND password='$upass'");
$match = mysqli_fetch_assoc($search);
if ($match == 1 and $match['password'] == md5($upass))
{
$_SESSION['username'] = $match['userid'];
} else {
?>
<script>alert('Password or E-mail is wrong. If you havent registered, Please Register');</script>
<?php
}
}
if (isset($_SESSION['username']) or isset($match['userid'])){
header("Location:start.php");
}
if (isset($_POST['btn-signup']))
{
$name = mysqli_real_escape_string($_POST['name']);
$usern = mysqli_real_escape_string($_POST['username']);
$email = mysqli_real_escape_string($_POST['email']);
$password = mysqli_real_escape_string($_POST['password']);
$repassword = mysqli_real_escape_string($_POST['repassword']);
$name = trim($name);
$usern = trim($usern);
$email = trim($email);
$password = trim($password);
$repassword = trim($repassword);
$query = "SELECT email FROM $user_table WHERE email='$email'";
$result = mysqli_query($connection, $query);
$count = mysqli_num_rows($result);
$querytwo = "SELECT username FROM $user_table WHERE username='$usern'";
$resulttwo = mysqli_query($connection, $querytwo);
$counttwo = mysqli_num_rows($resulttwo);
if ($count == 0 AND $counttwo == 0)
{
if ($password == $repassword) {
if (mysqli_query($connection, "INSERT INTO $user_table(username, email, password, realname) VALUES ('$usern','$email','$password','$name')"))
{
?>
<script> alert ('Successfully registered'); </script>
<?php
}
}else {
?>
<script> alert ('The Password you entered, doesnt match.. Please fill in the same password'); </script>
<?php
}
}
else {
?>
<script> alert('Username or E-mail already exist'); </script>
<?php
}
}
?>
and this is for require.inc.php
<?php
global $username;
//require 'dconn.php';
session_start();
$_SESSION["username"] = $username;
$connection = mysqli_connect("localhost","root","", "test") or die(mysqli_error());
// Check Login
if (isset($_SESSION['username']) and isset ($match['userid']))
{
$Selection = "SELECT * FROM $user_table WHERE username='$username'";
$selectQuery = mysqli_query($connection, $Selection);
if ($selectQuery != false)
{
while ($fetchD = mysqli_fetch_assoc($selectQuery))
{
$usernn = $fetchD['username'];
$email = $fetchD['email'];
$uid = $fetchD['userid'];
}
} else {
echo mysqli_error();
}
}
?>
#suggestion, create session after user login and authorized then for each page start session and take session which you created and perform SQL queries using that session variable.
for example :
$_SESSION['user_name']=$row['username'];
for each page:
session_start();
$user_name=$_SESSION['user_name'];
SQL query
mysqli_query($con,"SELECT * FROM users where column_name='$user_name'");
I think you need to include dconn.php file in all files where you want to perform the mysql operation. If you have included it only in require.inc.php then you you it in all your other files.
Hello i just want to check if the user (who is logging in) has usertype Employer then he should redirect to my-profile.php and if usertype is Jobseeker then he should redirect to latest-jobs.php. Here is my code please help me if you can.
I am trying to add some script in my code but it has some mistake and not working. Now it's redirecting to latest-jobs.php to both (Employer and Jobseeker). Check down my second script.
Thanks
<?php
session_start();
include("lib/conn.php");
?>
<?php
$email=$_POST['user'];
$password=$_POST['password'];
if ($email && $password){
$query = "SELECT * FROM register WHERE email = '$email' AND password= '$password' and status = '1'";
$result = mysql_query( $query ) or die ("didn't query");
$num = mysql_num_rows( $result );
if ($num == 1){
$_SESSION['ocer']=$email;
header("Location: my-profile.php");
}
else {
header("Location: index.php?l=1");
}
}
?>
My second script
<?php
session_start();
include("lib/conn.php");
?>
<?php
$email=$_POST['user'];
$password=$_POST['password'];
if ($email && $password){
$query = "SELECT * FROM register WHERE email = '$email' AND password= '$password' and status = '1'";
$result = mysql_query( $query ) or die ("didn't query");
$num = mysql_num_rows( $result );
if ($num == 1){
$_SESSION['ocer']=$email;
if ($usertype == "Employer") {
header("Location: my-profile.php");
}
else {
header ("Location: latest-jobs.php");
}
}
else {
header("Location: index.php?l=1");
}
}
?>
I got the solution now.
<?php
session_start();
include("lib/conn.php");
$email=$_POST['user'];
$password=$_POST['password'];
if ($email && $password)
{
$query = "SELECT * FROM register WHERE email = '".$email."' AND password= '".$password."' and status = '1'";
$result = mysql_query($query) or die ("didn't query". mysql_error());
$num = mysql_num_rows($result);
if($num ==1){
$data = mysql_fetch_array($result);
if($data['usertype'] == 'Employer')
{
$_SESSION['ocer'] = $email;
header("Location: my-profile.php");
}
else if($data['usertype'] == 'Jobseeker')
{
$_SESSION['ocer'] = $email;
header("Location: latest-jobs.php");
}
}
else{
header("Location: index.php?l=1");
}
}
?>
so I have my site which i am coding, in my login.php, this is the source:
<?php
include "out_config.php";
session_start();
$username = mysql_real_escape_string($_POST['username']);
$password = mysql_real_escape_string($_POST['password']);
if(!$username) {
header("Location: ../index?errormsg=nousername");
}
if(!$password) {
header("Location: ../index?errormsg=nopassword");
}
$sql = "SELECT * FROM users WHERE username='$username' and password='$password'";
if($rankcheck == "Administrator" || $rankcheck == "Client") {
$check = 1;
}
else {
$check = 0;
}
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1 && $check == 1) {
$_SESSION['username'] = $username;
header("Location: ../home");
}
else {
header("location: ../index?errormsg=invalidlogin");
}
}
?>
1st: I know MySQL is depreciated but I want to use MySQL because my Host Supports MySQL more than MySQLi/PDO.
2nd: You can see my $rankcheck won't work. My rank check lines are included in out_config.php, the source for it is:
<?php
<Removed Details>
$connect = mysql_connect($host, $username, $password);
$selectdb = mysql_select_db($db);
$IP = getenv('REMOTE_ADDR');
$sql2 = mysql_query("SELECT `rank` FROM `users` where username='$user'");
if(isset($_SESSION['username'])) {
$user = $_SESSION['username'];
$rankcheck = mysql_result($sql2,0);
}
?>
So you can see, it looks all fine. :P
Now, the problem is that I am trying to allow access to this area only to people who are ranked 'Administrator' and 'Client' so it won't work. My Database structure is:
http://i.stack.imgur.com/AAzr9.png
It does not grant access to User and Awaiting usergroup members. But it does not even let Administrator's and Clients. ( I am sure there is no Password Encryption yet ).
If you could help me, it would be really helpful!
in the moment you are including your "out_config.php" $username and $password is not set
change to this:
<?php
session_start();
$username = mysql_real_escape_string($_POST['username']);
$password = mysql_real_escape_string($_POST['password']);
include "out_config.php";
if(!$username) {
header("Location: ../index?errormsg=nousername");
}
if(!$password) {
header("Location: ../index?errormsg=nopassword");
}
$sql = "SELECT * FROM users WHERE username='$username' and password='$password'";
if($rankcheck == "Administrator" || $rankcheck == "Client") {
$check = 1;
}
else {
$check = 0;
}
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1 && $check == 1) {
$_SESSION['username'] = $username;
header("Location: ../home");
}
else {
header("location: ../index?errormsg=invalidlogin");
}
}
?>
