[SOLVED] If statement for login script. Multiple conditions

GameYin · April 28, 2008

<?php
session_start();
include 'config.php';  
$user = $_POST['username'];
$pass = $_POST['password'];
$query = mysql_query("SELECT * FROM Users WHERE Username = '$user' AND Password = '$pass' LIMIT 1") or die(mysql_error());
$row = mysql_fetch_array($query);

if($name != "" && $pass != "" || mysql_num_rows($query) > 0 || $row['Activated'] > 0) {
$_SESSION["status"] = "Logged";
$_SESSION['username'] = $user;
$_SESSION['password'] = $pass;
header("Location: index.php");
exit;
}
else {
$_SESSION["status"] = "Not logged";
$_SESSION['username'] = Guest;
echo "Something went wrong";
}
?>

www.gameyin.com/login.php

Enter these details

Admini <-- User

gameyin <--Pass

It always enters the error message when you hit submit

$user = $_POST['username'];
$pass = $_POST['password'];
$query = mysql_query("SELECT * FROM Users WHERE Username = '$user' AND Password = '$pass' LIMIT 1") or die(mysql_error());
$row = mysql_fetch_array($query);

if($user != "" && $pass != "" || mysql_num_rows($query) > 0 || $row['Activated'] > 0) {
$_SESSION["status"] = "Logged";
$_SESSION['username'] = $user;
$_SESSION['password'] = $pass;
header("Location: index.php");
exit;
}

Stupid error, but you set $user = $_POST['username'], then you compare $name to "". Change the variable name like I did in the above code.

Also, is Guest a global? Look where you're setting username to Guest.

GameYin · April 28, 2008

Hmm, I was rewriting the variables, I figured that $user was better then $name. My bad. Also what about globals? I'm bad at those...Is it because I didn't enclose Guest with ""?

I rewrote it with correct variable name and it sent me back to index.php. Can you write an if statement for my index.php to see if session variable is set? Or echo it?

revraz · April 28, 2008

Yes

Is it because I didn't enclose Guest with ""?

GameYin · April 29, 2008

Allright. That was 1 of 2 things I noticed I did differently. Accidental lol. So how can I echo my session on index.php

GameYin · April 29, 2008

Erm, anyone? Simple question.

How can I echo my session var.

GameYin · April 29, 2008

Help help help.

craygo · April 29, 2008

echo $_SESSION['username'];

same way you echo any other variable.

GameYin · April 29, 2008

I have the code in my index.php. I login but nothing is echoed. www.gameyin.com (Register, login then goto index.php) Something is wrong with my loginaction.php I guess? OR...

loginaction.php

<?php
session_start();
include 'config.php';  
$user = $_POST['username'];
$pass = $_POST['password'];
$query = mysql_query("SELECT * FROM Users WHERE Username = '$user' AND Password = '$pass' LIMIT 1") or die(mysql_error());
$row = mysql_fetch_array($query);

if($user != "" && $pass != "" || mysql_num_rows($query) > 0 || $row['Activated'] > 0) {
$_SESSION["status"] = "Logged";
$_SESSION['username'] = $user;
$_SESSION['password'] = $pass;
header("Location: index.php");
exit;
}
else {
$_SESSION["status"] = "Not logged";
$_SESSION['username'] = Guest;
echo "Something went wrong";
}
?>

index.php

You have to start your session on index.php. FIRST THING!

<?php
session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<body>

If you are using sessions, session_start() HAS to be the first thing on every page you write.

GameYin · April 29, 2008
