I’m having problems with a code I am trying to make.
[php]
<?php
/* Functions in this file */
/**************************/
// login()
// register()
// register_form()
?>
<?php
ini_set ("display_errors", "1");
error_reporting(E_ALL);
function register() {
include "connect.php";
$con = mysql_connect($host, $uname, $pass) or die(mysql_error());
mysql_select_db($dbname, $con) or die(mysql_error());
$username = trim($_POST['username']);
$password = trim($_POST['password']);
$pass_conf = trim($_POST['pass_conf']);
$email = trim($_POST['email']);
//Check the Data
if (empty($username)) {
die ("Fill in a username!");
}
if (empty($password)) {
die ("You forgot to fill in a password!");
}
if (empty($pass_conf)) {
die ("Confirm your password");
}
if (empty($email)) {
die ("We can't register you without an email");
}
$patt = "^[A-Za-z1-9 _-]+$";
if (!ereg($patt, $username)) {
die("Invalid characters in your username");
}
if (!ereg($patt, $password)) {
die("Invalid characters in your password");
}
if (!ereg("^.+@.+$", $email)) {
die ("Invalid email format.");
}
if ($password != $pass_conf) {
die ("The two passwords do not match!");
}
//Check to see if username is in use already.
$sql = mysql_query("SELECT username from users WHERE username = '".$username."'") or
die(mysql_error());
$num_rows = mysql_num_rows($sql);
if ($num_rows > 0) {
die ("Username already exists!");
}
//Check to see if email is in use or not.
$sql2 = mysql_query("SELECT email from users WHERE email = '".$email."'") or die
(mysql_error());
$num_rows2 = mysql_num_rows($sql2) or die(mysql_error());
if ($num_rows2 > 0) {
die ("E-mail is in use!");
} else {
$new_pass = md5($password);
$query = "INsERT INTO users (username, password, email)
values ('".$username."', '".$new_pass."', '".$email."')";
$mysql = mysql_query($query) or die (mysql_error());
if ($mysql) {
die("Works");
} elseif(!$mysql) {
die (mysql_error());
}
$_SESSION['status'] = "Loggedin";
$_SESSION['username'] = $username;
$message = "Welcome, ".$username."You are now logged in.
Log
in";
echo $message;
}
}
function register_form() {
echo "
![]()
Please register below
| Username |

Password: |

";
}
function login() {
header("Location: index.php");
}
switch($_GET['act']) {
case "register":
register();
break;
case "login":
login();
break;
default:
register_form();
}
?>
[/php]
I know that the switch works because it goes through and checks all the information. However, right after it checks to see if a username or email already exists, it completely stops working. Does anyone know why?
You should be able to trace the bug that way.
