Yo!

[Toy]

I'm doing something for the fun of it but I've kinda reached a problem!

 

I have the login and index page on the same...eh, page, so I log in using the "login form" and it works fine, but I want it so that after i login the login form dissapears, I tried assigning a cookie to fix this but I can't go that way so yeah, help me!

[Maq]

Can you post some relevant code?

[Toy]

<?php
if($_SERVER["REQUEST_METHOD"] == "POST")
{
$username=mysql_real_escape_string($_POST['username']);
$password=mysql_real_escape_string($_POST['password']);
$password=md5($password);
$sql="SELECT xx FROM xx WHERE username='$username' and password='$password'";
$result=mysql_query($sql);
$count=mysql_num_rows($result);
if($count==1)
{
echo 'This part is only visible if logged in!';
}
else
{
echo 'Sorry! The details you provided were incorrect, please try again...';
}
}
?>

<form action='<?php echo $_SERVER['PHP_SELF']; ?>' method='post'>
Username: 
<input type='text' name='username' class='input'>
Password: 
<input type='password' name='password' class='input'>
<input type='submit' value='Login' class='input'>
</form>

<?php
session_start();

if(!isset($_SESSION['logged_in'])) {
$_SESSION['logged_in'] = false;
}

if($_SESSION['logged_in'] == false)
{
if($_SERVER["REQUEST_METHOD"] == "POST") {
$username=mysql_real_escape_string($_POST['username']);
$password=mysql_real_escape_string($_POST['password']);
$password=md5($password);
$sql="SELECT xx FROM xx WHERE username='$username' and password='$password'";
$result=mysql_query($sql);
$count=mysql_num_rows($result);
if($count==1)
{
$_SESSION['logged_in'] = true;
header("Location: ".$_SERVER['PHP_SELF']);
}
else
{
echo 'Sorry! The details you provided were incorrect, please try again...';
}
}
} else {
// Use it here instead
echo 'This part is only visible if logged in!';
}
?>

<?php if($_SESSION['logged_in'] == false) { ?>
<form action='<?php echo $_SERVER['PHP_SELF']; ?>' method='post'>
Username: 
<input type='text' name='username' class='input'>
Password: 
<input type='password' name='password' class='input'>
<input type='submit' value='Login' class='input'>
</form>
<?php } ?>

 

In theory the above will work. It may need a little modification as I have not tested it.

Thank you!

 

I now get a "Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs"

 

on line:

 

header("Location: ".$_SERVER['PHP_SELF']);

 

very tired right now, sry if I'm bothering you with something stupid

[BlueSkyIS]

is there really a blank line or ANYTHING before <?php

 

if so, there can't be.

It appears that you haven't posted the complete code, and you haven't posted the complete error message. That makes it more difficult for others to actually help you.

[Toy]

It's okay! I got it :-)

 

that's all for now I hope. 

[Toy]

one last thing, I'm having kind of a problem with echoing out the username or whatever value of the logged in user, I don't really know why, could someone provide a working snippet of code that does this, I'd be forever grateful?

[Maq]

You already have the value, why can't you just output it?

[Toy]

Look, I don't really know! Every way I've tried just doesn't seem to work.
