<?php

function redirect_to_index_with_error(){
    echo '<meta http-equiv="refresh" content="0;url=index.php">';
}

function go_to_home(){
    echo '<meta http-equiv="refresh" content="0;url=home.php">';
}

$email = mysql_real_escape_string($_POST['username']); echo $email;
$pwd = mysql_real_escape_string($_POST['password']);
echo $pwd;
$query = "SELECT * FROM users WHERE email='$email' AND password=MD5('$pwd')";
echo "query variable created.";

mysql_connect("localhost","root","") or die(mysql_error());
echo "connected."; //nothing

mysql_select_db("mcp") or die(mysql_error());

$results = mysql_query($query) or die(mysql_error());

if(mysql_num_rows($results) == 0){
    redirect_to_index_with_error();
    exit();
}

$userID = null;
$name = null;
$school = null;
$mod = null;

while($user = mysql_fetch_array($results)){
    $userID = $user['ID'];
    $name = $user['Name'];
    $school = $user['School'];
    if($user['Mod'] == '1')
        $mod = true;
    else
        $mod = false;

}
if(!isset($_SESSION))
    session_start();

//set session variables
$_SESSION["userID"] = $userID;
$_SESSION["name"] = $name;
$_SESSION["school"] = $school;
$_SESSION["mod?"] = $mod;

go_to_home();
exit();
?>

PHP echos everything up until “connected”. It’s not even showing a mysql error. I’ve had this code work flawlessly on Windows with WAMP, but not on Mac with MAMP. I’ve verified that the servers are running, so I can’t tell what the problem is. I’m using PHP 5.3.6.

Your connection needs to be established before you call mysql_real_escape_string()

So move mysql_connect("localhost","root","") or die(mysql_error()); to the top.
