Similar TutorialsHey there guys, I have been trying to resolve this myself the past hour or so and I can't seem to figure it out. I am in the middle of programming a contacts database, with a login system. Now, the register.php file I created to create users for the database works, but the following code is from my login.php file. When I am on the page in my browser and I type in a registered username and password combination it simply just reloads the login.php file, with blank form fields, as if you had just loaded the page. I am not quite sure what is causing this. Here is the code from my login.php file: <?php //Database Information $dbhost = "removed_for_this_post"; //Host Name $dbname = "removed_for_this_post"; //Database Name $dbuser = "removed_for_this_post"; //Database Username $dbpass = "removed_for_this_post"; //Database Password //Connect To Database mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error()); mysql_select_db($dbname) or die(mysql_error()); session_start(); $username = $_POST['username']; $password = md5($_POST['password']); $query = "SELECT * FROM users WHERE username='$username' AND password='$password'"; $result = mysql_query($query); if (mysql_num_rows($result) != 1) { $error = "Bad Login"; include "login.html"; } else { $_SESSION['username'] = "$username"; include "main_interface.php"; } ?> Thanks for your help in advance!! Hey guys ive put together a super simple login and i can figure out the problem since it just wont create the sessions and echo the default error If anyone has any idea why i am getting this issue that would be awesome Code: [Select] <?php session_start(); // dBase file include "../admin/config.php"; if (!$_POST["username"] || !$_POST["password"]) { die("You need to provide a username and password."); } // Create query $q = "SELECT * FROM `nm_users` WHERE `username`='".$_POST["username"]."' AND `password`=PASSWORD('".$_POST["password"]."') LIMIT 1"; // Run query $r = mysql_query($q); if ( $obj = @mysql_fetch_object($r) ) { // Login good, create session variables $_SESSION["valid_id"] = $obj->id; $_SESSION["valid_user"] = $_POST["username"]; $_SESSION["valid_time"] = time(); // Redirect to member page Header("Location: members.php"); } else { // Login not successful die("Sorry, could not log you in. Wrong login information."); } ?> I am totally new in PHP, can anyone help me with this problem:
Login Button is not working after clicking this button this should print a echo message.
<from action="" method="POST">
<input type="text" placeholder="username"> <br>
<input type="password" placeholder="Password"><br>
<input type="submit" name="login" value="Login">

<?php if ( isset($_POST['login'])){

Hi, I made a login/register system and it was working fine, but now I seem to have broken it and I'm scratching my head as to why. I think it's something to do with the $_SESSION array, the error happens from going from the login.php page to members.php, I log in successfully, but when I get to the members page it says "you must be logged in". index.php has the form to login or a link to register.php to make an account Code: [Select] <?php session_start(); ?> <html> <head> <title>Lincs Crusade | Login page.</title> </head> <body> <form action="login.php" method="POST"> Username: <input type="text" name="username"><br /> Password: <input type="password" name="password"><br /> <input type="submit" value="Login"> </form> <a href="register.php">Click here to register!</a> </body> </html> The register.php page Code: [Select] <?php session_start(); echo "<h2>Register</h2>"; $submit = $_POST['submit']; $username = strip_tags($_POST['username']); $password = strip_tags($_POST['password']); $repeatpassword = strip_tags($_POST['repeatpassword']); $email = $_POST['email']; $date = date("Y-m-d"); if ($submit) { if ($username&&$password&&$repeatpassword&&$email) { if ($password==$repeatpassword) { if (strlen($username)>65) { echo "Length of username is too long!"; } elseif (strlen($email)>100) { echo "Length of email is too long!"; } elseif (strlen($password)>65||strlen($password)<8) { echo "Password must be between 8 and 65 characters long!"; } else { include('functions.php'); echo "All fields were accepted!

I'm making a login/sign up page and the following pieces are not working together properly. When I set up the login page following a guide, it had me direct input the structure and I added a user (password is encrypted). When I log in with that password/username, it passes authentication.php perfectly. When I use my signup form (signup.php is simply called by a button on an HTML), it fails saying "Incorrect Password!". I'd say it's failing because of encryption but it passes with my old login that is encrypted so I'm thoroughly lost. Authentication.php

Anyway, that's the background to why I'm about to ask a really simple question: I wrote a login script, and it rejects people correctly who don't have the correct credentials, and it accepts the people that do, but while the failed attempts send the appropriate alert (the alert also pops up when u first open the page, which if you all can figure out why and stop it, that would be awesome, but its not the main problem), for those who do log in it does not send them to the link that I'm trying to send them to upon log in. Instead, they stay on the same page, but the login text boxes are gone. Any help would be appreciated, thanks.

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.
I am stuck at sending the users' data to the original site. The original site's viewsource is this..
<form method=post> <input type="hidden" name="action" value="logon"> <table border=0> <tr> <td>Username:</td> <td><input name="username" type="text" size=30></td> </tr> <tr> <td>Password:</td> <td><input name="password" type="password" size=30></td> </tr> <td></td> <td align="left"><input type=submit value="Sign In"></td> </tr> <tr> <td align="center" colspan=2><font size=-1>Don't have an Account ?</font> <a href="?action=newuser"><font size=-1 color="#0000EE">Sign UP Now !</font></a></td> </tr> </table>I have tried this code, but not works.

This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=348317.0 My code does not have any errors.

//Login if(!empty($username)) { // Check the email with database 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? 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!"

Hi everyone i wonder if you can help me he I need a script for a login and check login- create cookie. Here is my form: <form method="post" action="check_login.php"> <p> <input type="submit" name="Submit2" value="go" /> </fieldset> </p> </form> that sends it to check_login (which BEFORE i deleted something by accident, used to take me to a username and password box) But now all it does is send me straight to the memebrs area??? 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 } ?> |
