Php Login Script - Removing the login field once the user logs in

Hey everyone. I have a login script that i know works. My question is that on my main page, it have a form to allow the user to log in. What i want it to do is that once the user logs in, the form disappears and the users data (aka username) is displayed where the form was. At the moment i cant get it to work. Below is my code.

CODE

<div id="loginMenu">
<?php
if ($logged_in == 1)
{
?>

<?php
}//if
else
{
?>

<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
<table border="0" cellspacing="1" cellpadding="0">
<tr><td>Username: </td></tr>
<tr><td><input type='text' name='uname' size='17'></td></tr>
<tr><td>Password:</td></tr>
<tr><td><input type='password' name='passwd' size='17'></td></tr>
<tr><td><input type="submit" name="submit" value="Login"> <input type="submit" name="submit" value="Register"> </td></tr>
</table>
</form>

<?php
}//else
?>
</div>

What happens with this code is that it only will display the form because the user isnt logged in. If i refresh the page in IE it will then display it. There has to be a way to dynamically change it once the user submits the form. THanks for the help

Use code tags for code. This is your warning.

I think you need a tag,
Or one of those other thingies which ashs a question,

Is user logged in?

Yes:
Welcome [username.]

No:
Display:

CODE

Google it, On what whe script is, Or ask an admin.
I need a login page for my sit too, & in the end i just gave up.

OK thanks for the reply and sorry about not using the code tag. i didnt even notice that it was a tag so sorry.

What i was asking was that it would display the login box in the loginMenu div but once the user hits submit in the form, that the user logs in (which my script works) and then instead of showing the loginMenu, it would display the users information. Thats what the if (loggedIn) was for but what i think happens is when the user logs in, the page isnt refreshed so it doesnt even see whats in the if.

Hopefully someone can help. Thanks agian and sorry about not using the code tag

NO WAIT, SORRY!

Put this on your index page,

-----------------------------------------------------------------------------------------------

CODE

<?

session_start();

$uid = $_SESSION['uid'];
$pwd = $_SESSION['pwd'];

require('main.php');

db_connect();

include(INC_DIR."header.php");

if ($uid){

echo "<br>already logged in";

} else {

echo "<br><Span Class=emph>Members Log In</SPAN>";

include(INC_DIR."login.php");

echo "<Span Class=emph>Not a Member? Join Now!</SPAN>";

include(INC_DIR."signup.php");

}

include(INC_DIR."footer.php");

db_disconnect();

?>

-----------------------------------------------------------------------------------------------

Without the dashes, Youll have to configure all the variables, Like
'include(INC_DIR."footer.php");'

THIS IS DEFINETLY RIGHT, USE THIS BUT YOULL HAVE TOO DO IT.
Sorry for the mix-up.

Thanks,
FFC Webmaster,
Asad Haider.

This is your FINAL WARNING!!!
If you do not use [code][/code] tags to put in codes again, you will lose your facilities here!

i think fffanatics already has his own auth system. and his code works. i think it's with $logged_in not beeing assigned with the right value.

Yeah i know my auth system works cause i can produce a login script that works when on a separate page. However, who wants to change pages just to log in. It has to be with teh $logged_in variable. This is the order of operations that need to happen along with which ones work:

1.) Users enters fffanatics and decides to log in using the form (works - it is the else)

2.) THe user hits submit and is authenticated (works)

3.) Now instead of the form still being on the page, it should display the users information instead (doesnt work)

I just cant seem to get to form to go away after the user hits submit. Hopefully this clarifies the issue.

i belive that there is no way you can gather all the data about the user when he logs in and then display it with out another page or a script processes it. you have to make your script log the user in then redirect it again to the page with his details displayed.

OK so if i understand all of you correctly, what i should do is have the user log in (run my log in script) and then redirect them to the correct page that would contani their information?

I have my website set up that after you go to the index page, you must log in to go futher. Once you log in, you are directed to another index page with a Welcome! script and member-specific info. When you set up your form to process, direct the form to a processing page that verifies your user then directs to a welcome page (a copy of your index) and modify that page to whatever welcome content you wish!

This is my form processing code:

CODE

In checkuser.php, after all variables have been checked and the user verified, I have this:

CODE

if($login_check > 0){
while($row = mysql_fetch_array($sql)){
foreach( $row AS $key => $val ){
$$key = stripslashes( $val );
}
session_register('first_name');
$_SESSION['first_name'] = $first_name;
session_register('last_name');
$_SESSION['last_name'] = $last_name;
session_register('email_address');
$_SESSION['email_address'] = $email_address;
session_register('special_user');
$_SESSION['user_level'] = $user_level;
$_SESSION['auth'] = true;

mysql_query("UPDATE users SET last_login=now() WHERE userid='$userid'");

header("Location: welcome.php");

}}
else {
echo "<center><font color=red><strong>You could not be logged in! Either the username and password do not match or you have not validated your membership!<br />
Please try again!</strong></font></center><br />";
include 'index.php';
}

I hope some of this helps you. I know that was a huge chunk of code for just a little info, but I was afraid of leaving out something you might need. Good luck!

Yes my code does work and i do actually use cookies. I use to cookies so that they have the option of not having to sign in for 2 weeks. However, this is the only information that is cantained in the cookie. Personally, i like sessions cause its very easy to use and is a secure way to send and recieve information from a page

Why not just use cookies to keep your users logged in? It's a lot easier using sessions, in my opinion. All you would have to do is add a new variable to the config file that is something like this:

CODE

$username = (isset($_COOKIE['user']) ? $_COOKIE['user'] : Guest);

CODE

<?php

# Include all the needed files

if (isset($_POST['login'])) {
$uname = $_POST['username'];
$pword = $_POST['password'];
$check = mysql_query("SELECT username FROM users WHERE username='$uname' AND password='$pword'") or die(mysql_error());
if (mysql_num_rows($check) == 0) {
echo 'Invalid username or password';
exit;
} else {
setcookie('user', $uname, time()+999999);
setcookie('pword', $pword, time()+999999);
echo 'You have successfully logged in! Return to the <a href="/">index</a>.';
}
} else {
echo '';
}

?>

Hey everyone thanks for your help. My login script works 100% now. The error was because i had a blank line after the ?> in the one file i included. Thanks for all of your great ideas and solutions

Hmmz thanks for the help but i am not looking to really rewrite a good amount of my code. I just was wondering if anyone knew how i could fix this error since it must be a small one if i dont get it on my server but do get it on the trap17 one

Instead of directing the user to the registration page right away , you could just echo that they are not registered and then give them a link to the registration page.

I am a newbie php'er, but:

CODE

<?
$register=$_POST['register'];
$login=$_POST['login'];

if($register){
echo "Please register first";
header("location: register.php");
}
else {
if($login){
$username=$_POST['username'];
$password=$_POST['password'];
$remember=$_POST['remember'];
}
if($remember==1){
$member_class=check_login($username, $password, true);

echo "succesfully logged in, redirecting you";
header("location: membersarea.php");
}
else { $member_class=check_login($username, $password, false);
echo "The username and/or password you provided is wrong";
header("location: login.php");
}
$logout=$_POST['logout'];
if($logout){
$member_class=logout();
}
}

Its probably completely wrong (doh!) but it was worth a shot, what i dont understand is the use of ->, is that actually php?
