PHP is being a ***** again >.<

I started with 7 errors.... I've now cut it down to 3... (Im only just learning PHP, Much of it, as i need it in making my site, or improvising on HTML/Premade PHP)

Warning: Cannot modify header information - headers already sent by (output started at /www/1111mb.com/u/g/n/ugnetwork/htdocs/index2.php:7) in /www/1111mb.com/u/g/n/ugnetwork/htdocs/index2.php on line 93

And heres line 87 - 104.... So much writing.. my brain hurts.

// 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['pass'], $hour);

//then redirect them to the members area
header("Location: index3.php");
}

}

} else {

Any ideas anyone?

(BTW: I get this when i try to login after ive entered my details (username and pass)

not sure if this will work. i would prefer if you would post the whole script cause you might be duplicating variables, and are you connecting to your database and using query's, etc.?

// if login is ok then we add a cookie

$user = stripslashes($_POST['username']);
$pass = $_POST['pass'];

$hour = time() + 3600;
setcookie('ID_my_site', $user, $hour);
setcookie('Key_my_site', $pass, $hour);

//then redirect them to the members area
header("Location: index3.php");
}

}

K, The Whole script is

<script language="JavaScript" type="text/JavaScript">

<body bgcolor="#000000"><body>

<center><hr>

<?php

// Connects to your Database
mysql_connect("lHidden, "Hidden", "Hidden") or die(mysql_error());
mysql_select_db("ugnetwork_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['password'])
{

}

else
{
header("Location: index3.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['pass']) {
die('You did not fill in a required field.');
}

// checks it against the database

if (!get_magic_quotes_gpc()) {
$_POST['username'] = addslashes($_POST['username']);
}

$check = mysql_query("SELECT * FROM users WHERE username = '".$_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 ))
{

$_POST['pass'] = stripslashes($_POST['pass']);
$info['password'] = stripslashes($info['password']);
$_POST['pass'] = md5($_POST['pass']);

//gives error if the password is wrong

if ($_POST['pass'] != $info['password']) {
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['pass'], $hour);

//then redirect them to the members area

Ill try that what you said now

Its because php has started to render the page and then you are trying to using cookies. There is this php code;
ob_start()
php.net link

MockingMonkey · Jan 20, 2007 at 6:12 PM

Try removing the cookies and see if that helps in anyway. If it doesn't just make it so that it forces its way through.

Ruler46 · Jan 20, 2007 at 6:14 PM

Soo thats soo complicated in that link lol...... >.<

You need to have the cookie saved inorder to acsess the members part, thats how I stop people just rewriting the URL to the next page, and I think it'll be needed too.

Would, Once they've entered their login info they got redirected to a new page, that page saves the cookie then redirects them to the members area work? And if yeah, could anybody give me a little hint how to do that...

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

Common stuff to know.
Anyway, if you did/didn't make that code, there are some things you can/should change.

For instances, unless you plan on allowing more then one member to have the same Username, then you can just change:
Code:
while($info = mysql_fetch_array( $check ))
to
Code:
if($info = mysql_fetch_array( $check ))

if you have MSN, pm me it, and i will help you with the script over MSN. i am currently working on a script similar to yours for a class/experiment.

johndapunk FTW · Jan 20, 2007 at 11:12 PM

a simple login script for an experiment?

Under619Taker · Jan 20, 2007 at 11:54 PM

no. a entire member system, written from scratch with php and mysql. i am only about a month and a half working with real php instead of just includes, and echos, etc.
