PHP - Simple Login Issues
Hello,
I created a simple login script, taht has a hard coded user/pass. Yet for some reason it will not work, keeps redirecting to the main login page Here is the code Login Page Code: [Select] <table width='400' border='0' align='center' cellpadding='0' cellspacing='0'> <tr> <td>UserName:</td> <td><form action="loginscript.php" method="post"> <input name="username" type="text" size="10"></td> </tr> <tr> <td>Password:</td> <td><input name="password" type="password" size="10"></td> </tr> <tr> <td colspan='2' align='center'><input name="Submit" type="submit" value="Submit"></form></td> </tr> </table> Login Script Code: [Select] <?php session_start(); $pass = strtolower($_POST['password']); $name = strtolower($_POST['username']); if($name == "test" && $pass == "test"){ header ("location: select.php"); } else{ // invalid login, so go back ... header ("location: index.php"); } ?> Select.php Code: [Select] <?php session_start(); if(isset($_SESSION['myuser'])){ } else{ header ("location: index.php"); } ?> ANy ideas why it is not working. It doesnt seem like it is going through the login on the loginscript as all it does is redirect back to index page over and over again Similar TutorialsHello, im very green to php and I am having trouble creating a simple log in script. Not sure why this is not working, maybe a mysql_query mistake? I am not receiving any errors but nothing gets updated in the members table and my error message to the user displays. any help is appreciated! here is my php: <?php session_start(); $errorMsg = ''; $email = ''; $pass = ''; if (isset($_POST['email'])) { $email = ($_POST['email']); $pass = ($_POST['password']); $email = stripslashes($email); $pass = stripslashes($pass); $email = strip_tags($email); $pass = strip_tags($pass); if ((!$email) || (!$pass)) { $errorMsg = '<font color="#FF0000">Please fill in both fields</font>'; }else { include 'scripts/connect_db.php'; $email = mysql_real_escape_string ($email); $pass = md5($pass); $sql = mysql_query("SELECT * FROM members WHERE email='$email' AND password='$pass'"); $log_check = mysql_num_rows($sql); if ($log_check > 0) { while($row = mysql_fetch_array($sql)) { $id = $row["id"]; $_SESSION['id']; $email = $row["email"]; $_SESSION['email']; $username = $row["username"]; $_session['username']; mysql_query("UPDATE members SET last_logged=now() WHERE id='$id' LIMIT 1"); }//Close while loop echo "You are logged in"; exit(); } else { $errorMsg = '<font color="#FF0000">Incorrect login data, please try again</font>'; } } } ?> and the form: <?php echo $errorMsg; ?> <form action="log_in.php" method="post"> Email:<br /> <input name="email" type="text" /><br /><br /> Password:<br /> <input name="password" type="password" /><br /><br /> <input name="myBtn" type="submit" value="Log In" /> </form> Hi, Okay, i have no idea what's gone wrong here - yesterday my codes were working fine, and today they arent. I have not changed a single letter of the coding on these pages but my site just isnt accepting my passwords. When i went to create a new user i noticed this at the top of the page: Quote Warning: session_start() [function.session-start]: open(/tmp/sess_28f02ccd11ec3beb8ff8b5762400b605, O_RDWR) failed: Read-only file system (30) in /home/a9203152/public_html/PHP-Login/register-form.php on line 5 but i dont really know what it is telling me is wrong? i've tried changing the file permissions etc but like i say, nothing has changed even a little bit. maybe its my computer or something?? the site is www.cumbrianadverts.com if anybody wants to try making an account to see what im talking about. any help is appreciated Thanks I'm going to post two scripts my login.php and my register.php problem is i'm always getting usernamepassword don't match i think something to do with md5 but can't figure out where... or why? <?php session_start(); $login = $_POST['login']; $password = $_POST['password']; if ($login&&$password) { $connect = mysql_connect("localhost","heaven","jefF0614") or die ("could not connect to server"); mysql_select_db("heaven_users") or die ("could not find database"); $query = mysql_query("SELECT * FROM members WHERE username='$login'"); $numrows = mysql_num_rows($query); if($numrows!=0) { while ($row = mysql_fetch_assoc($query)) { $dbusername = $row['username']; $dbpassword = $row['password']; } // check to see if they match if($login==$dbusername&&$password==$dbpassword) { echo "Your In <a href='member.php'>click here to go to the member page</a>"; //start session $_SESSION['username']=$login; } else echo "Incorrect Password/Username Combination"; } else die("That username dose not exist"); } else die ("Please enter a username and password"); ?> and register.php <?php //check for submit $submit =$_POST['submit']; //gather POST variable $fullname =strip_tags($_POST['fullname']); $email =strip_tags($_POST['email']); $username =strip_tags($_POST['username']); $password =strip_tags($_POST['password']); $password2 =strip_tags($_POST['password2']); if ($submit) { //check that fields were filled in if ($fullname&&$email&&$username&&$password&&$password2) { //check to see if our two password fields match if ($password==$password2) { $password = md5($password); // register the user //open database $connect = mysql_connect("localhost", "heaven", "jefF0614"); mysql_select_db("heaven_users"); //begine insert $queryreg = mysql_query("INSERT INTO members VALUES ('','$fullname','$email','$username','$password')"); if ($queryreg) { echo "Thanks, For Registering!

I am trying to create the login for the admin section of my project, but facing issues again. I can't seem to get the code to check to see if the username and password submitted through the login form is correct as per what is in the database. Here is the form: Code: [Select] <form action="authenticate.php" method="post" name="frmLogin" id="frmLogin"> <table width="400" border="1" align="center" cellpadding="2" cellspacing="2"> <tr> <td width="150">User Id</td> <td><input name="txtUserId" type="text" id="txtUserId"></td> </tr> <tr> <td width="150">Password</td> <td><input name="txtPassword" type="password" id="txtPassword"></td> </tr> <tr> <td width="150"> </td> <td><input name="btnLogin" type="submit" id="btnLogin" value="Login"></td> </tr> </table> </form> The authenticate.php: <?php session_start(); // Start a new session require('../config/config.php'); // Holds all of our database connection information // Get the data passed from the form $username = $_POST['user']; $password = $_POST['password']; // Do some basic sanitizing $username = stripslashes($username); $password = stripslashes($password); $sql = "select * from users where username = '$username' and password = '$password'"; $result = mysql_query($sql) or die ( mysql_error() ); $count = 0; while ($line = mysql_fetch_assoc($result)) { $count++; } ?> The errors I get: Code: [Select] Warning: mysql_query() [function.mysql-query]: Access denied for user 'danoid'@'localhost' (using password: NO) in /home/danoid/public_html/admin/authenticate.php on line 14 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /home/danoid/public_html/admin/authenticate.php on line 14 Access denied for user 'danoid'@'localhost' (using password: NO) Any one got any ideas? hi again guys n gals. Ive just pre-built a website that works fine. ive just moved all files to another server and now when i try to login it does nothing , also if i try to signup it gives this error ................. Code: [Select] Warning: gethostbyaddr() [function.gethostbyaddr]: Address is not a valid IPv4 or IPv6 address in /home/content/70/6589670/html/gaming/signup.php on line 87 i have NOT edited the code in anyway so m guessing its a server issue ... or could i be wrong ??? any help welcome , thanks for reading I'm completely new to programming in PHP so I looked up a tutorial on youtube, came across the phpacademy tutorial for making a login page script. I followed everything as mentioned in the video but for some reason, I can login without a username or password entered and on top of that it's not displaying any of the messages I added in the code. I'm using Xampp for my Apache server and MySQL, configured everything I should of (as far as I know) but it still refuses to work. Here's the html for the login page, just a basic form. Code: [Select] <html> <form action='login.php' method='POST'> Username: <input type='text' name='username'><br> Password: <input type='password' name='password'><br> <input type='submit' value='Log in'> </html> And then we have the PHP code which isn't working AT ALL. It's like it's not reading it at all for some reason and I can't figure out why. Code: [Select] <?php $connect = mysql_connect("localhost", "root", "") or die("Couldn't connect!"); mysql_select_db("phplogin") or die("Couldn't find DB"); $connection =@ mysql_connect($db['server'], $db['user'], $db['password']) or die (include_once("offline.php")); $db =@ mysql_select_db($db['database']) or die (include_once("offline.php")); if($_POST['username'] && $_POST['password']){ $username = trim($_POST['username']); $password = trim($_POST['password']); $query = mysql_query("SELECT * FROM `users` WHERE `username` = '$username' AND `password` = '$password'"); $numrows = mysql_num_rows($query); if ($numrows > 0){ echo "Username & Password correct (Logged in)"; } else { echo "That user doesn't exist"; } } else { echo "Please enter a username and password!"; } ?> One thing I should mention is that, if I try to login on firefox it shows part of my php code as text, if I open it on Opera it displays the whole php code as text. Any ideas? -.-' Dear PHPFreaks, I am new to PHP. Currently I'm trying to get a PHP login to write to file and use that file to register member and then allow users to login by reading through the file. Here is the code so far. Any help would be grateful. <body> <form action="register.php" method="post"> <h2>Register:</h2> <p> <label for="runame">Username:</label> <input name="runame" id="runame" value="" type="text" /> </p> <p> <label for="rpword">Password:</label> <input name="rpword" id="rpword" type="password" /> </p> <p> <input name="register" value="Register here" type="submit" /> </p> </form> </body> register.php <?php if (isset($_POST['submit'])) { $runame = $_POST['uname']; $rpword = $_POST['pword']; $category = "user"; } $fh = fopen("password.txt","a+"); $data = $runame . ":" . $rpword . ":" . $category . "\n"; fwrite($fh, $data); fclose($fh); ?> I've tried Googling this for a long time but I only find complete member systems with ugly code, not something i'm looking for. What I am looking for is just a simple tutorial or commented code to make a admin login. What it's going to do is just: Loading a MD5 salt hasched password from my MYSQL database. You'll get to fill in one field: Password. If it validates with the MYSQL password it'll show the hidden content; if not it'll just give a "not correct error". That's basicly it. I have only one page of secret admin stuff so yeah.. it would be awesome to have the ability to logout and I of curse want to have everything in sessions! It would be to big help! I'm very new to PhP and one of my asignments in class is to create a simple login using php and mysql. I made a simple page using html, php, and mysql and i keep getting errors. Here is my code so far: This is my index.php page: <html> <form action = 'login.php' method='POST'> Username: <input type='text' name='username'><br> Password: <input type='password' name='password'><br> <input type='submit' value='Log in'> </form> </html> This is my login.php page: <?php $username = $_POST['username']; $password = $_POST['password']; if ($username&&$password) { &connect = mysql_connect("localhost", "root", " ") or die ("Couldnt connect"); mysql_selct_db("phplogin") or die("Couldn't find db"); } else die ("Please enter a username and password"); ?> mySql file is very basic: 3 columns, id, username, password I dont think my problem is with the mySQL page that was the easiest to make but everytime I hit login in the index.php, the entire script for login.php gets outputted on screen. I would appreciate all the help. Hi, I've been trying to get a simple select statement to work in my code, and I just don't know why it returns an error. Quote Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /adoptnow.php on line 13 And the code is: Code: [Select] <?php $con = mysql_connect("localhost","***","***"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("a8784hos_pets2", $con) or die ("Couldn't select database because: ".mysql_error()); $query = "SELECT * FROM species WHERE available = 1"; $petcrap = mysql_query($query) or die ("Error in number one query: $query. ".mysql_error()); $petinfo = mysql_fetch_array($petcrap); while ($row = mysql_fetch_array($petinfo)){ echo $row['petid']; } ?> I've read that this is usually because you haven't selected the database or it can't find the table, but I've run the sql query in phpmyadmin, and it comes back perfectly. I honestly have no idea what I'm doing wrong right now and would appreciate some help. Thanks. I have a form on my website which actions login.php. The login.php code is below: <?php include('includes/classes.php.inc'); session_start(); $link = new BaseClass(); $data = $link->query("SELECT * FROM logins"); $pass_accepted = false; if($_REQUEST['username'] && $_REQUEST['password']){ $username = $_REQUEST['username']; $password = $_REQUEST['password']; while($row = mysql_fetch_array($data)){ if(($row['username']==$useranme)&&($row['password']==$password){ echo 'Password correct!'; $_SESSION['loggedin']=true; $pass_accepted = true; } } } else { echo 'You did not enter a username or password!'; } if(!$pass_accepted){ echo 'Your password is incorrect'; } echo '<br>Please <a href="index.php">click here</a> to return to page'; ?> I have checked that my references are all correct however even when I enter the correct password it returns saying the password is incorrect. Any idea on why this could be? I am happy to answer any follow up questions. Regards Hi there, I have a simple login script written but I get an error with it. It does work but shows an error on some pages. Let me explain. Three Files: Admin.php Login.html checklogin.php When the user has logged in they go to checklogin.php. If the username and password match 1 row in the database then it forwards the user to admin.php fine. Except I keep getting mysql warning messages: Warning: Cannot modify header information - headers already sent by (output started at /home/wormste1/public_html/tilburywebdesign/shop/templates/template1/admin/updatescompanyinformation.php:3) in /home/wormste1/public_html/tilburywebdesign/shop/templates/template1/admin/companyinfoupdated.php on line 3 At the start of each page I want password protected I put the following code: <? session_start(); if(!session_is_registered(myusername)){ header("location:login.html"); } ?> I can't work out why I am getting this error. Many Thanks, Ian Hey I would just like to release a simple login/register script that will work just fine and has some nice systems in it. The Login. (I will post the code then below tell you what you need to do to get it to work with MYSQL DATABASE) Create a file and call it login with the suffix .php so if you have file extensions showing on your computer it will look like "login.php" then put this code inside of it. Code: [Select] <?php session_start(); ?> <?php function mysql_prep($value) { $magic_quotes_active = get_magic_quotes_gpc(); $new_enough_php = function_exists("mysql_real_escape_string"); // i.e PHP >= v4.3.0 if($new_enough_php){ // PHP v4.3.0 or higher if ($magic_quotes_active){ $value = stripslashes($value); } $value = mysql_real_escape_string($value); }else{ //Before PHP v4.3.0 //if magic quotes aren't already on then add slahes manually if(!$magic_quotes_active){ $value = addslashes($value); } // if magic quotes are active then the slashes already exist } return $value; } function redirect_to($location = NULL){ if($location != NULL){ header("Location: {$location}"); exit; } } define("DB_SERVER","localhost"); define("DB_USER","root"); define("DB_PASS","yourpassword"); define("DB_NAME","yourdatabasename"); $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if(!$connection){ die("Database Connection Failed: " . mysql_error()); } $db_select = mysql_select_db("bcooperz", $connection); if(!$db_select){ die("Connection to database failed: " . mysql_error()); } ?> <?php if(isset($_SESSION['user_id'])){ redirect_to("staff.php"); } ?> <?php if (isset($_POST['submit'])){ $errors = array(); // Perform validations on the form $required_fields = array('username', 'password'); foreach($required_fields as $fieldname){ if(!isset($_POST[$fieldname]) || empty($_POST[$fieldname])){ $errors[] = $fieldname; } } $field_with_lengths = array('username' => 30, 'password' => 30); foreach($field_with_lengths as $fieldname => $maxlength) { if (strlen(trim(mysql_prep($_POST[$fieldname]))) > $maxlength) { $errors[] = $fieldname; } } $username = trim(mysql_prep($_POST['username'])); $password = trim(mysql_prep($_POST['password'])); $hashed_password = sha1($password); if (empty($errors)){ // Checks database to see if username and password exist their $query = "SELECT id, username FROM users WHERE username='$username' AND hashed_password='$hashed_password' LIMIT 1"; $result_set = mysql_query($query, $connection); if(!$result_set){ die("Database Query Failed: " . mysql_error()); } if (mysql_num_rows($result_set) == 1) { // The Username and Password have been found in the database and the user is verified // Only 1 Match $found_user = mysql_fetch_array($result_set); $_SESSION['user_id'] = $found_user['id']; $_SESSION['username'] = $found_user['username']; redirect_to("staff.php"); }else{ // Username and Password was not found in the database. $message = "Username/Password Combination Incorrect.<br/>Please make sure your caps lock key is off and try again."; echo $message; } }else{ $count = count($errors); if($count == 1){ echo "Their Was {$count} Error In The Form" . "<br />"; print_r(implode(", ", $errors)); }else{ echo "Their Was {$count} Error's In The Form" . "<br />"; echo "<b>"; print_r(implode(", ", $errors)); echo "</b>"; } } }else{ // The Form Has Not Been Submitted if(isset($_GET['logout']) && $_GET['logout'] == 1){ echo "You Are Now Logged Out"; } if(isset($_GET['nowlogged']) && $_GET['nowlogged'] == 1){ echo "You Need to Login to reach this page."; } $username = ""; $password = ""; } ?> <html> <head> <title>Register</title> </head> <body> <form action="login.php" method="post"> Username : <input type="text" name="username" maxlength="30" value="<?php echo htmlentities($username); ?>" /><br /> Password : <input type="password" name="password" maxlength="30" value="<?php echo htmlentities($password); ?>" /><br /><br /> <input type="submit" name="submit" value="Login" /><br /> </form> <p>Haven't got an account? register <a href="register.php">here!</a></p> </body> </html> Now once you have a file called "login.php" with the above code inside of it you will need to goto your mysql database and create a database with a table that has 3 fields in the following format. - id - int(11) - Auto increment - username - varchar(50) - hashed_password - varchar(40) Now search for this in the login.php code Code: [Select] define("DB_SERVER","localhost"); define("DB_USER","root"); define("DB_PASS","yourpassword"); define("DB_NAME","yourdatabasename"); And This: Code: [Select] $db_select = mysql_select_db("bcooperz", $connection); And change these to your settings. Once you have done all this create a new file called register with the suffix .php as well so if you have file extensions turned on it will look like "register.php" And add this code inside it: Code: [Select] <?php function mysql_prep($value) { $magic_quotes_active = get_magic_quotes_gpc(); $new_enough_php = function_exists("mysql_real_escape_string"); // i.e PHP >= v4.3.0 if($new_enough_php){ // PHP v4.3.0 or higher if ($magic_quotes_active){ $value = stripslashes($value); } $value = mysql_real_escape_string($value); }else{ //Before PHP v4.3.0 //if magic quotes aren't already on then add slahes manually if(!$magic_quotes_active){ $value = addslashes($value); } // if magic quotes are active then the slashes already exist } return $value; } function redirect_to($location = NULL){ if($location != NULL){ header("Location: {$location}"); exit; } } ?> <?php define("DB_SERVER","localhost"); define("DB_USER","root"); define("DB_PASS","maxcooper"); define("DB_NAME","bcooperz"); $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if(!$connection){ die("Database Connection Failed: " . mysql_error()); } $db_select = mysql_select_db("bcooperz", $connection); if(!$db_select){ die("Connection to database failed: " . mysql_error()); } ?> <?php if(isset($_POST['submit'])){ $username = trim(mysql_prep($_POST['username'])); $password = trim(mysql_prep($_POST['password'])); $hashed_password = sha1($password); $confirmpass=$_POST['confirmpass']; $query2 = "SELECT * FROM users WHERE username='$username'"; $result2 = mysql_query($query2); $counted=mysql_num_rows($result2); $errors = array(); // Perform validations on the form $required_fields = array('username', 'password', 'confirmpass'); foreach($required_fields as $fieldname){ if(!isset($_POST[$fieldname]) || empty($_POST[$fieldname])){ $errors[] = $fieldname; } } if($confirmpass!=$_POST['password']){ $errors[] = "passdifference"; } if($counted > 0){ $errors[] = "User Already Created"; } $field_with_lengths = array('username' => 30, 'password' => 30); foreach($field_with_lengths as $fieldname => $maxlength) { if (strlen(trim(mysql_prep($_POST[$fieldname]))) > $maxlength) { $errors[] = $fieldname; } } /* The Form Has Been Submitted */ if (empty($errors)){ $query = "INSERT INTO users (username,hashed_password) VALUES ('{$username}', '{$hashed_password}')"; $result = mysql_query($query, $connection); if($result){ echo "User Successfully Created"; }else{ echo "The User Could Not Be Created" .

Thanks, Bcooperz. Please tell me if this works I am trying to learn php and I cannot figure out how to get a simple login form going. I am getting this error.

Edited by Oblivion13, 07 October 2014 - 05:25 PM. Hi Everyone, Just wondered if someone could quickly help me out, im building a simple login system for my website but having a little bit of trouble, the error i keep getting is: Quote Cannot modify header information - headers already sent by (output started at /home/sites/cuju8.com/public_html/include.php:18) in /home/sites/cuju8.com/public_html/login.php on line 12 I have done some research but cant find the answer to this, my login script is as follows: Code: [Select] <?php require_once('include.php'); $error = ''; $form = $_POST['submit']; $email = $_POST['email']; $password = $_POST['password']; if( isset($form) ) { if( isset($email) && isset($password) && $email !== '' && $password !== '' ) { $sql = mysql_query("SELECT * FROM `usersystem` WHERE email='$email' and password='$password';"); if( mysql_num_rows($sql) != 0 ) { //success $_SESSION['logged-in'] = true; [b]header('Location: members.php');[/b] exit; } else { $error = "Incorrect login info"; } } else { $error = 'All information is not filled out correctly';} } ?> I think its the header location code thats causing the problem but im not sure where to move it too. If anyone could help i would really appreciate it. Cheers Hello, I am learning php in a class for school and I was hoping I could get some help with some code. I am trying to make a game life counter. I just want it to have simple +1, -1 and reset buttons. I have gotten it to add and subtract the first time, but it will not continue adding/subtracting. Thank you for any help you can give. Here is the code I'm having issues with: <?php session_start(); ?> <form method="post" action =""> <input type="submit" name="name" value="Add"/> <input type="submit" name="name" value="Minus"/> <input type="submit" name="name" value="Reset"/> </form> <? lifeTotal(); function lifeTotal() { $_SESSION['total']=20; if($_POST["name"] == 'Add') { $_SESSION['total']++; echo $_SESSION['total']; } else if($_POST["name"] =='Minus') { $_SESSION['total']--; echo $_SESSION['total']; } } ?> I have a Login page which i want to check if the user details (username, password and activation) are valid then redirect user dependent on his/her "accessLevel" (admin, member and none)
Admin will be directed to "index.php"
Member will be directed to "tasks.php"
and none will be redirected to "notActive.php"
here is my current code which half works;
<?php
include ('connect.php');
if(isset($_POST['submit'])) {
// Initialize a session:
session_start();
// Define $username and $password
$username=$_POST['username'];
$password=$_POST['password'];
// To protect MySQL injection
$username = stripslashes($username);
$password = stripslashes($password);
$username = mysql_real_escape_string($username);
$password = mysql_real_escape_string($password);
$sql="SELECT * FROM ecmt_members WHERE username='$username' and password='$password' AND Activation IS NULL";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $username and $password, table row must be 1 row

When i test it with admin login credentials i get the page refresh again without error, when i login with member credentials it shows tasks.php and when i try to log in with unactivated account "acivation column is not NULL" i get a page refresh also with no error.
Can someone help me make it work for each role and perhaps have some sort of error reporting depending on error.
im pulling my hair out here and this is the first time i have worked with login conditions, and im VERY confused.
Edited by jacko_162, 28 October 2014 - 05:12 PM. Hello everyone: I wanted to see how I can make a simple login page (user name and password) that redirects to a page(s) if the login is correct. Also, I wanted to put protection on the page(s) that will send the user back to the login page if the credentials are nor correct. I would imagine the username/password would be stored in a database table (Admins), and the correct login info would be stored in a session ..? I am use to doing this with ASP, but never PHP. I want to make sure I understand how to do this properly and securely so I can use this as a model for other systems. In ASP I would do a protected page like this: a_login_check.asp Code: [Select] <% if session("admin_user_name") = "" then session.abandon response.redirect "login.asp" end if %> Protected-Page.asp Code: [Select] <!-- #include file="include/a_check_login.asp" --> <html> ... CONTENT ... </html> And of course there is the login page itself ... (I thought it would be nice to add a "Forgot Password" link on the login page, but if that is too complicated I can do that later .. or is it easy ??) Anyway, can someone point-out to me how to do this. I would appreciate it! ok..ive done this a million times..i have a working example here and i copied it and amended it for this new project but for some reason i cant get a form to post data to another page. this is the error message i get Notice: Undefined index: username in C:\wamp\www\uni\fyp\site\mobile\login.php on line 16 Notice: Undefined index: password in C:\wamp\www\uni\fyp\site\mobile\login.php on line 17 here is my form code: <form method="post" action="login.php"> <table align="center" cellpadding="0" cellspacing="0"> <tr> <td style="vertical-align:top;">Username: </td><td><input type="text" name="username" value="" /></td> </tr> <tr> <td style="vertical-align:top;">Password: </td><td><input type="password" name="password" value="" /><br /><input type="submit" id="submit" value="Login" /></td> </tr> </table> </form> and here is the code within the login.php where the form should post to $username = $_POST['username']; $password = $_POST['password']; // Help protect against MySQL injection $username = stripslashes($username); $password = stripslashes($password); $username = mysql_real_escape_string($username); $password = mysql_real_escape_string($password); // Selecting data from database where correct username and password are found $sql="SELECT * FROM customer WHERE username='$username' and password='$password'"; $result=mysql_query($sql) or die(mysql_error()); i cant see anything wrong..been looking for hours...please please help me hi i need help an idea how can i separate members from admins since i dont know how to create login form i used tutorial ( http://www.youtube.com/watch?v=4oSCuEtxRK8 ) (its session login form only that i made it work other tutorials wre too old or something) how what i want to do is separate members and admins because admin need more rights to do now i have idea but dont know will it work like that what i want to do is create additional row in table named it flag and create 0 (inactive user) 1 (member) 2 (admin) will that work? and how can i create different navigation bars for users and admins? do you recommend that i use different folders to create it or just script based on session and flag? |
