PHP - Basic Login Page Help!!

Hi,

I am a php newbie, who has a page that relies on some php scripts, and to which I am trying to add a login page written in php.  I took the example from he

http://www.howtodothings.com/computers-internet/how-to-make-a-login-system-for-your-website

Basically it consists of adding:

<?
require("log.php");
?>

to the top of any page I want to protect, a log.php file which performs the actions of the form, linking to a mySQL database, and a login.php file which contains the form.

I have the login working fine, but it breaks one of the PHP scripts on the page that is protected.  It is an upload script, called Weaverbox, based on FancyUpload.  The uploads which are handled by a file called upload.php, aren't happening.  The progress shows that they are being uploaded, but nothing is uploaded, and there is no success message.  As soon as I remove the code from the top of the page requiring log.php all works fine again.

I think I may have to add some rules/extensions to resolve this conflict, but I don't know how to go about this.  Would someone be able to help me get it sorted?

Thanks

Nick

Can someoneplease help, I need to setup an error page like IF Username and Password are wrong then show an error also if there is no username or password in the fields and I just click LOGIN, I get a blank page?!

Can someone please help me here or point me to a relevant tutorial?

thanks

here is my page:
http://www.retroandvintage.co.uk/default.php

here is my  code:
Code: [Select]
<?php
session_start();
include_once("config.php");

$ebits = ini_get('error_reporting');
error_reporting($ebits ^ E_NOTICE);
/*
Login script:
This script does the following:

Checks that the user is NOT already logged in - if they are they
are redirected to the members page by the 'checkLoggedIn()' function.

Checks if the login form has been submitted - if so, the 'login' and
'password' fields are checked to ensure they are of the correct format and length.
If there are any problems here an error is added to the $messages array and
then the script executes the 'doIndex()' function - this function basically
outputs the main 'index' page for this script - ie the login form.

If there are no problems with the previous step, the 'login' and 'password'
field data is passed to the 'checkPass' function to check that an entry
exists in the 'users' table for that login/password pair.
If nothing is returned from the 'checkPass()' function, an error is
added to the $messages array and the 'doIndex()' function is called as above.

If a row of data is returned from the 'users' table, the data is passed to
the 'cleanMemberSession()' function - which initializes session variables and
logs the user in.  The user is then forwarded to the members page.

If the form hasn't yet been submitted, then the 'doIndex()' function is called
and the login page is displayed.
*/
// Check user not logged in already:
checkLoggedIn("no");

// Page title:
$title="Member Login Page";

// if $submit variable set, login info submitted:
if(isset($_POST["submit"])) {

// show the index page (where the messages will be displayed):

// the lines below will be processed:

// now check the user/pass pair match those stored in the db:

If checkPass() is successful (ie the login and password are ok),
then $row contains an array of data containing the login name and
password of the user.
If checkPass() is unsuccessful however, $row will simply contain
the value 'false' - and so in that case an error message is
stored in the $messages array which will be displayed to the user.
*/
    if( !($row = checkPass($_POST["rsUser"], $_POST["rsPass"])) ) {
// login/passwd string not correct, create an error message:
        $messages[]="Incorrect login/password, try again";
    }

/*
If there are error $messages, errors were found in validating form data above.
Call the 'doIndex()' function (which displays the login form) and exit.
*/
if($messages){
doIndex();
exit;
}

/*
If we got to this point, there were no errors - start a session using the info
returned from the db:
*/
cleanMemberSession($row["rsUser"], $row["rsPass"]);

// and finally forward user to members page (populating the session id in the URL):

} else {
// The login form wasn't filled out yet, display the login form for the user to fill in:

/*
This function displays the default 'index' page for this script.  This consists of just a simple

ONE of my SESSION values isn't remaining after login while others do.

This works fine on my localhost, it's on the live site that there is a problem and it just started yesterday. Before that it worked great.

Out of the four SESSIONs made I can only echo three values on other pages, member id the most important doesn't transfered to other pages

Notes: all these files are in the same folder, there is a SESSION started for the member id on the login page, you can see that it is used in the redirect below and the redirect works fine with the redirect going to the correct page " $home/member/index.php?user=$id_mem "

Here is the login page
// Here's the basic login page info
<?php # login.php
session_start();
ob_start() 
...connect to db & header called...
...Form validation.....

if ($e && $p) { // If everything's OK.
// Query the database:
$q = "SELECT id_mem, display_name, mem_group FROM sn_members WHERE (email='$e' AND password=SHA1('$p')) AND active IS NULL";
$r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc));
//  or die("Error: ".mysqli_error($dbc));

if (@mysqli_num_rows($r) == 1) { // If a match was made.

// Register the values & redirect:
// Give SELECTED elements a session
$_SESSION = mysqli_fetch_array ($r, MYSQLI_ASSOC);
$_SESSION['agent'] = md5($_SERVER['HTTP_USER_AGENT']);
mysqli_free_result($r);

// Update db for last login
$id_mem = $_SESSION['id_mem']; // <<< SESSION member id has a value here because it's used in the redirect below
$ip = $_SERVER['REMOTE_ADDR']; // Get ip address of person logging in
$q = "UPDATE sn_members SET last_login = Now(), ip = '$ip' WHERE id_mem = '$id_mem' LIMIT 1";
$r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc));

header("Location: $home/member/index.php?user=$id_mem");
exit(); // Quit the script.

}
?>


Here is the main page that a user would be redirect to above
<?php // /member/ all member info is through this folder
session_start();
ob_start();

if (isset($_GET['user']) && is_numeric($_GET['user'])) {
$user = $_GET['user'];
$user = $user;
if ($user < 0) {
header("Location: $home/index.php");
exit();
}
}

if ((!isset($_SESSION['id_mem']))  && (!isset($_SESSION['agent']) OR ($_SESSION['agent'] != md5($_SERVER['HTTP_USER_AGENT'])))){
// If not a logged in member redirect
header("Location: $home/index.php");
exit(); // Quit the script.
}
?>

Thanks in advance for the help

I'm trying to set up a very simple (WIP) members page that you can click registered users to see their profile page that will display basic information.

I'm having trouble with the sessions and retrieving this info from my database. I'm very new to this so it's all pretty amateur.

I've been looking at this code for several hours trying to fix things but I start to make some progress, then change stuff, and go backwards. I had a members page that displayed the registered users in my database, but after a while of altering to try to get the profiles to work, I messed it up :mad:. I have basic login and register pages.

I need some seperate eyes to take a look. Any help is so much appreciated. Thanks!

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

 

This is the code any suggestions would be greatly appreciated

Hey guys i have a few question with this login script im trying to make. Ok so first im using php myadmin and i've created a simple login here that works fine but i want to tweak it so when i login i can login to a specific site where i've created tables and stuff. Is there anyone out there that can help me im a little stumped on how to do this. Thanks in regards. Here are my two scripts im using


show_login.html
Code: [Select]
<html>
<head>
<title>Login Form</title>
<h1>Login to Authorized Area</h1>
<form method= "post" action= "login.php">

<br> Username: <input type= "text" name= "username"> <br>
<br> Password: <input type= "password" name= "password"> <br>

<p> <input type= "submit" name= "submit" value= "Login" </p><br>
</html>
</form>

login.php
Code: [Select]
<?

if ((!$_POST['username']) || (!$_POST['password'])) {

Hi,
On my website I have a booking calendar which you login to with a username and password.  That interactive part of the website now looks very different from the rest of the website, but unfortunately it's not possible to recode that calendar to look like the rest of the site.

As a workaround I'd like users to be able to login to that calendar from the home page, with just a simple username and password field at the top of the page.  On submit this would then send the details to the existing login page, and also log them in straight away.  My php knowledge is limited.  I've searched a lot on Google but can't find any code that seems to do the trick.  Does anyone know if this is even possible?

thanks in advance

Please help with Ajax call, when clicking login button nothing happens when it should go to mainpageloggedin.php

deano

I had a success page redirect after the login...but the login happens even if the username and password is not entered. you can check it in colonialcasa.org

here's the code for the login.php page ( i have obviously changed the server name, database and password for privacy reasons )

<?

/*simple checking of the data*/
if(isset($_POST['login']) & isset($_POST['pass']))
{

/*Connection to database logindb using your login name and password*/
$db=mysql_connect('servername','login','password') or die(mysql_error());
mysql_select_db('mpahost_logindb');

/*additional data checking and striping*/
$_POST['login']=mysql_real_escape_string(strip_tags(trim($_POST['login'])));
$_POST['pass']=mysql_real_escape_string(strip_tags(trim($_POST['pass'])));

$q=mysql_query("SELECT * FROM login WHERE login='{$_POST['login']}' AND pass='{$_POST['pass']}'",$db) or die(mysql_error());

/*If there is a matching row*/
if(mysql_num_rows($q) > 0)
{
   $_SESSION['login'] = $_POST['login'];
   $login='Welcome back '.$_SESSION['login'];
}
else
{
   $login= 'Wrong login or password';
}

mysql_close($db);

}
/*Use of Sessions*/
if(!session_id())

header("Location: advocates.html"); // success page. put the URL you want

header("Cache-control: private"); //avoid an IE6 bug (keep this line on top of the page)

$login='NO data sent';

//you may echo the data anywhere in the file
echo $login;

?>

This is my one page log in system. Using this on the header so guests can log in on ANY page. Let me know what you think needs improving for security. I'm also wondering if putting the include "disconnect.php"; where I have is correct. Thanks!

I have written some php that forces login before accessing certain pages on my site.  When a user sends an private message to another user, they are notified via email.  In the email they can then click the view message link to take them right to the message, but if they aren't logged in they are sent to the login page.  I'd like them to be redirected to the message after logging in, but I'm getting a php error.

This is currently working for URL's like: domain.com/known-bugs

Does NOT work: http://domain.com/messaging?action=read&cid=130&utm_source=new_message&utm_medium=email&utm_campaign=direct_mesage_link

I think the query string is a problem in the script. To create this login feature. I am using...

Code: [Select]
$login = array(
'blogadd',
'messaging',
'company-settings',
'company-landing',
'company-create',
'company-join',
'account-settings',
'logout',
'home',
'newsadd',
'partnerRequest',
'known-bugs',
'reminders'
);

$page = substr(end(explode(DIRECTORY_SEPARATOR, $_SERVER['PHP_SELF'])), 0, -4);

if (in_array($page, $login))
{
$urlSource = urlencode(curPageUrl());
header("Location: /login?onlogin=${urlSource}");
die();
}

curPageURL is just the full url of the current page.

WORKS: When I'm not logged in and I go to the known-bugs page I get redirected to http://domain.com/login?onlogin=http%3A%2F%2Fdomain.com%2Fknown-bugs

DOESN'T WORK: When I try and access messaging by clicking...

http://domain.com/messaging?action=read&cid=130&utm_source=new_message&utm_medium=email&utm_campaign=direct_mesage_link

I get redirected to:
http://domain.com/login?onlogin=http%3A%2F%2Fdomain.com%2Fmessaging%3Faction%3Dread%26cid%3D130%26utm_source%3Dnew_message%26utm_medium%3Demail%26utm_campaign%3Ddirect_mesage_link

Any thoughts as to what I am doing wrong?

My main pages looks like this...

<?php
include "header.php";

CONTENT

include "footer.php";
?>

On the header will be my login script so on every page the script will be there so they can log in from anywhere on the site. Also, I want it all done on one page instead of being directed somewhere else. This is the code below.

<?php
session_start();

$message = ""; //error message needs to be blank
$loginstatus = ""; //error message needs to be blank

//if $_POST "username" and "password" exist, check for consistency.
if (isset($_POST['username'])&&($_POST['password']))
{
include 'connect.php'; //connect
$username = mysql_real_escape_string($_POST['username']); //set variables from session
$password = mysql_real_escape_string($_POST['password']); //set variables from session

//remove slashes and HTML
$username = stripslashes($username);
$password = stripslashes($password);
$username = strip_tags($username);
$password = strip_tags($password);

$password = md5($password); //md5 encryption

$query = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'"); //checking if row exists that has $username and $password together.
$num = mysql_num_rows($query); //number of rows. if not equal to one login will fail.

if($num==1)
{
$_SESSION['username'] = $username; //store session data
$message = "$username, you are logged in!";
}
else
{
$message = "<font color='red'>Wrong Username or Password. Please try again.</font>";
}
}

//if $_SESSION "username" and "password" exist, check for consistency.
if (isset($_SESSION['username']))
{
$username = $_SESSION['username'];
$loginstatus = "
<table cellspacing='0' cellpadding='0'>
<tr>
<td align='right'><b>$message</b> <a href='logout.php'>[logout]</a></td>
</tr>
</table>
";
}
else
{
$loginstatus = "
<b>$message</b>
<table cellspacing='0' cellpadding='0'>
<form action='CURRENTPAGE.php' method='post'>
<tr>
<td><b>Username: </td>
<td><input type='text' name='username' class='inputbox'></td>
<td>   <b>Password: </td>
<td><input type='password' name='password' class='inputbox'></td>
<td>   <input type='submit' value='Log In' class='submitbutton'></td>
</tr>
</table>
</form>
";
}

echo $loginstatus;

?>

I have two questions...

#1 How can I direct my page when entering the password to the current page the user is on? (look at CURRENTPAGE.php in the code for reference)

#2 Security is obviously an issue at all times. How does my security look? What can I do to make this login script more secure?

Thanks so much for all of those who help out. I'll be watching this forum all day everyday.

So I am having this problem on my page its my login.

Well its actually being included on my mainfile(index.php)

 <div id="login_content_one"><div id="login_one"><?php include('home.php') ?></div></div>

And this is my home.php code

echo "<form action='login.php' method='POST'>";

As it goes from home.php>login.php it changes to a different page, how can i maintain the trapping message like ("No username") on the same  page?

This is a good example, gerald.hengeraldtrading.com < check the login it goes on another page.
