I have made a simple login and registration system ( http://dak.esy.es/login/ ), and would like to retrieve other information from the same row in the MySQL database. Currently, only the username is saved (as $_SESSION['username']
), and this is what is entered on the login page. On the database, the data I want to be saved is id
, fullname
and email
- preferably in the same format as the username ( $_SESSION['(name here)']
). I already have a file to connect to the database called db.php
. If anyone could provide the code I would be greatly pleased. The code on my login.php
page is:
<?php
require('db.php');
session_start();
// If form submitted, insert values into the database.
if (isset($_POST['username'])){
$username = $_POST['username'];
$password = $_POST['password'];
$username = stripslashes($username);
$username = mysql_real_escape_string($username);
$password = stripslashes($password);
$password = mysql_real_escape_string($password);
//Checking is user existing in the database or not
$query = "SELECT * FROM `users` WHERE username='$username' and password='".md5($password)."'";
$result = mysql_query($query) or die(mysql_error());
$rows = mysql_num_rows($result);
if($rows==1){
$_SESSION['username'] = $username;
header("Location: ./index.php"); // Redirect user to index.php
}
else{
echo "<div class='form'><br/><h3>Username or password incorrect.</h3><br/>Click here to <a href='login.php'>try again</a></div>";
}
}
?>
Many thanks.
It is not clear what the requirement is: but i hope, you want every value from db row as session.. hope you have session: `$_SESSION['username'] after login;
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$query = "SELECT * FROM `tbl_login` WHERE `username` = ".$_SESSION['username'];
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);
$_SESSION['id'] = $row["id"];
$_SESSION['name'] = $row["fullname"];
$_SESSION['email'] = $row["email"];
mysqli_close($conn);
or for setting session along with login validation:
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$query = "SELECT * FROM `tbl_login` WHERE `username` = ".$_POST['username']." AND `password`= ".$POST['password'];
$result = mysqli_query($conn, $query);
$row = mysqli_fetch_assoc($result);
if(isset($row)){
$_SESSION['id'] = $row["id"];
$_SESSION['username'] = $row["username"];
$_SESSION['name'] = $row["fullname"];
$_SESSION['email'] = $row["email"];
} else {
redirect('login.php'); //reload login page on failure
}
mysqli_close($conn);
this is the basic code and you can split this code to MVC.
