PHP - Showing The Users Name After Login
Hi guys
I am new to PHP and need som help. I have set up a site that allows a user to log in through a simple form where the data is then send to checklogin.php. Here the data is checked up against my sql database and if the login is correct the user is transfered to the "secret" members only site. All this works fine. My question is then, how do I get the members site to greet the member with "Hello 'username'"; of course where the username changes depending on the login. This is the part where the username and password is checked: <?php $host="mydbb10.surftown.dk"; // Host name $username="****"; // Mysql username $password="****"; // Mysql password $db_name="****"; // Database name $tbl_name="members"; // Table name // Connect to server and select databse. mysql_connect("$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['myusername']; $mypassword=$_POST['mypassword']; // 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 $tbl_name WHERE username='$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 "korrekt.php" session_register("myusername"); session_register("mypassword"); echo "Tak fordi du loggede ind<br>Redirecter..."; header("location: ../forhandlerservice.php"); } else { echo "Forkert brugernavn eller password"; header("location: ../loginfejl.html"); } ?> and this is the first line of code on the members site: <? session_start(); if(!session_is_registered(myusername)){ header("location:login.html"); } ?> Sorry if I provided to much code, just want to make sure that I don't forget anything.

Hi, I have a restricted area for my work's company. This is an area where registered users with their own user name and password can access to download technical documents etc. I am hearing some reports that users will have to login twice to get to the area - This happens in Chrome, IE 7/8 and some Firefox's. It has only happened to me once or twice. Does anyone know why this may be?

I have a site that allows user to download some files. at present if i type http://www.abc.com/files/xyz.zip it allows all the users to access and download files. I want only the login users can access these files....... pls help how to do this. thanks in advance Hi! I have read like crazy to find a tutorial on a login page without My_SQL. Anyway I am working on a easy login/logged out page with sessions. Here is the login page with tree users in an array.
The things that I need some hints to solve is, when clicking on login the error message don't show. Instead the script goes to the logged in page right away. And when you write the wrong password you get loged in anyway.
I am not sure how or if it's possible to write a varible to a file this way. But I tried and recived a parse error with the txt varible.
When searching for topics I get more confused with the My_SQL varibles. I am near a breaking point at cracking the first step on PHP, but need some advice.
<?php $page_title = 'Logged in'; //Dynamic title include('C:/wamp/www/PHP/includes/header.html'); ?> <?php session_start(); //A array for the sites users with passwords $users = array( 'Dexter'=>'meow1', 'Garfield'=>'meow2', 'Miro'=>'meow3' ); //A handle to save the varible users to file on a new line from the last entry $handle = fopen("newusers.txt, \n\r") $txt = $users; fclose($handle); if(isset($_GET['logout'])) { $_SESSION['username'] = ''; header('Location: ' . $_SERVER['PHP_SELF']); } if(isset($_POST['username'])) { if($users[$_POST['username']] == $_POST['password']) { $_SESSION['username'] = $_POST['username']; }else { echo "Something went wrong, Please try again"; } } ?> <?php echo "<h3>Login</h3>"; echo "<br />"; ?> <!--A legend form to login--> <fieldset><legend>Fill in your username and password</legend> <form name="login" action="777log.php" method="post"> Username: <br /> <input type="text" name="username" value="" /><br /> Password: <br /> <input type="password" name="password" value="" /><br /> <br /> <input type="submit" name="submit" value="Login" /> </fieldset> </form> <?php //Footer include file include('C:/wamp/www/PHP/includes/footer.html'); ?>The logged in page <?php //Header $page_title = 'Reading a file'; include('C:/wamp/www/PHP/includes/header.html'); ?> <?php session_start(); //Use an array forthe sites users $users = array( 'Dexter'=>'meow1', 'Garfield'=>'meow2', 'Miro'=>'meow3' ); // if(isset($_GET['logout'])) { $_SESSION['username'] = ''; echo "You are now loged out"; //The user is loged out and returned to the login page header('Location: ' . $_SERVER['PHP_SELF']); } if(isset($_POST['username'])) { //Something goes wrong here when login without any boxes filled if($users[$_POST['username']] == $_POST['password']) { $_SESSION['username'] = $_POST['username']; }else { echo "Something went wrong, Please try again"; $redirect = "Location: 777.php"; } } ?> <?php if($_SESSION['username']): ?> <p><h2>Welcome <?=$_SESSION['username']?></h2></p> <p align="right"><a href="777.php">Logga ut</a></p><?php endif; ?> <p>Today Ben&Jerrys Chunky Monkey is my favorite!</p> <?php //Footer include('C:/wamp/www/PHP/includes/footer.html'); ?> I have dynamic images that have the "Like" button, it's basically like a wishlist. The way I want it to work is that when a user is not logged in, the 'Like' button will navigate them to a login popup (which I already made). I have a standard form that displays users current data from a mysql database once logged in(code obtained from the internet). Users can then edit their data then submit it to page called editform.php that does the update. All works well except that the page does not display the updated info. Users have to first logout and login again to see the updated info. even refreshing the page does not show the new info. Please tell me where the problem is as i am new to php.

I am trying to work out how many regular users I have to my site and how long those users tend to be users..
So, I have a table that logs every time a user visits my site and logs in, it stores the date / time as a unix timestamp and it logs their user id.
I started by getting the id's of any user who logs in more than 5 times in a specified period, but now I want to extend that...
SELECT userID as user, count(userID) as logins FROM login_history where timestamp > UNIX_TIMESTAMP('2014-06-01 00:00:00') and timestamp < UNIX_TIMESTAMP('2014-07-01 00:00:00') group by user having logins > 5; I just discovered that I have a major security flaw with my website. Anyone who logs in to the website can easily access other users information as well as delete and edit other users information just by changing the ID variable in the address bar. I have user ID Session started on these pages but still people can do anything they like with other users information just by editing the address bar. For example if your logged in in the address bar of www.mywebsite.com/delete_mystuff.php?id=5 and change the "5" say to a "9" then you will have access to user#9 information. Every important page that I have has this code: Code: [Select] session_start(); if (!isset($_SESSION['user_id'])) { // Start defining the URL. $url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']); // Check for a trailing slash. if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) { $url = substr ($url, 0, -1); // Chop off the slash. } // Add the page. $url .= '/index.php'; ob_end_clean(); // Delete the buffer. header("Location: $url"); exit(); // Quit the script. } else { //Else If Logged In Run The Script if((isset($_GET['id'])) && (is_numeric($_GET['id']))) { $id = (int) $_GET['id']; } elseif ((isset($_POST['id'])) && (is_numeric($_POST['id']))) { $id = (int) $_POST['id']; } else { echo ' No valid ID found, passed in url or form element'; exit(); } What am I doing wrong? Please help if you know how to correct this. Many thanks in advance. I am pretty new to PHP and am trying to create a simple (so I assumed) page to takes data from one html page(works fine) and updates a MYSQL Database. I am getting no error message, but the connect string down to the end of the body section is showing up as plain text in my browser window. I do not know how to correct this. I have tried using two different types of connect strings and have verified my names from the HTML page are the same as listed within the php page. Suggestions on what I need to look for to correct would be great. I have looked online, but so far all I am getting is how to connect, or how to create a comment, so I thought I would try here.

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 guys, Can anyone assist me. I am trying to create a login for admin and user (if user not a member click register link) below is my code: But whenever I enter the value as: Username: admin Password:123 - I got an error message "That user does not exist!"

Can i change the check_login.php script to make it work correctly: Code: [Select] <?php // Connects to your Database mysql_connect("server", "user", "password") or die(mysql_error()); mysql_select_db("DB") or die(mysql_error()); //Checks if there is a login cookie if(isset($_COOKIE['ID_my_site'])) //if there is, it logs you in and directes you to the members page { $username = $_COOKIE['ID_my_site']; $pass = $_COOKIE['Key_my_site']; $check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error()); while($info = mysql_fetch_array( $check )) { if ($pass != $info['upassword']) { } else { header("Location: members_area.php"); } } } //if the login form is submitted if (isset($_POST['submit'])) { // if form has been submitted // makes sure they filled it in if(!$_POST['username'] | !$_POST['upassword']) { die('You did not fill in a required field.'); } // checks it against the database if (!get_magic_quotes_gpc()) { $_POST['email'] = addslashes($_POST['email']); } $check = mysql_query("SELECT * FROM users WHERE username = '".$_POST['username']."'")or die(mysql_error()); //Gives error if user dosen't exist $check2 = mysql_num_rows($check); if ($check2 == 0) { die('That user does not exist in our database. <a href=register.php>Click Here to Register</a>'); } while($info = mysql_fetch_array( $check )) { $_POST['upassword'] = stripslashes($_POST['upassword']); $info['upassword'] = stripslashes($info['upassword']); $_POST['upassword'] = md5($_POST['upassword']); //gives error if the password is wrong if ($_POST['upassword'] != $info['upassword']) { die('Incorrect password, please try again.'); } else { // if login is ok then we add a cookie $_POST['username'] = stripslashes($_POST['username']); $hour = time() + 3600; setcookie(ID_my_site, $_POST['username'], $hour); setcookie(Key_my_site, $_POST['upassword'], $hour); //then redirect them to the members area header("Location: members_area.php"); } } } else { // if they are not logged in ?> <form action="<?php echo $_SERVER['PHP_SELF']?>" method="post"> <table width="316" height="120" border="0"> <tr><td colspan=2><h1>Login</h1></td></tr> <tr><td>Username:</td><td> <input type="text" name="username" maxlength="40"> </td></tr> <tr><td>Password:</td><td> <input type="password" name="upassword" maxlength="50"> </td></tr> <tr><td colspan="2" align="right"> <input type="submit" name="submit" value="Login"> </td></tr> </table> </form> <?php } ?> Hello, I am once again desperately asking for your help, I am working on a simple login page and I am having trouble actually getting it to login. I display error messages for if the user doesn't enter anything but I can't seem to get it to work for if the credentials are wrong. It logs the user in whether the information is right or not and i dont even know what to do now
