Alright, so I'm doing a pure dynamic AJAX site, and i've been on a register script for 2 days now, and for some reason, something about it makes it weird.

 

<?php
session_start();
require('require/connect.php');
require('require/clean_code.php');
$name = safe($_GET['user']);
if(isset($_GET['user'])) {
$pass = safe($_GET['pass']);
$email = safe($_GET['email']);
$gender = safe($_GET['gender']);
$class = safe($_GET['type']);
if($name=='') {
echo "Please enter a name.";
}
elseif($pass=='') {
echo "Please enter a password.";
}
elseif($email=='') {
echo "Please enter an email.";
}
elseif($gender != "Male" && $gender != "Female") {
echo "Please choose a legit gender.";
}
elseif($class != "Warrior" && $class != "Mage") {
echo "Please choose a legit class.";
}
else {
$q = mysql_query("SELECT * FROM `users` WHERE `name`='".$name."'");
$c = mysql_num_rows($q);
$q1 = mysql_query("SELECT * FROM `users` WHERE `email`='".$email."'");
$c2 = mysql_num_rows($q1);
if($c > '0') {
echo "This name is already in use.";
}
elseif($c1 > '0') {
echo "This email is already in use.";
}
else {
$pass2 = sha1($pass);
mysql_query("INSERT INTO `users` (`name`, `pass`, `email`, `type`, `gender`) VALUES ('".$name."', '".$pass2."', '".$email."', '".$class."', '".$gender."')") or die(mysql_error());
echo "You have successfuly registered, ".$name.".";
}
}
}
else {
?>
<head>
<script type='text/javascript' src='require/jquery.js'></script>
<script type='text/javascript' src='require/main.js'></script>
<script type='text/javascript'>
function function1() {
var user = window.document.reg.user.value;
var pass = window.document.reg.password.value;
var email = window.document.reg.email.value;
var gender = window.document.reg.gender.value;
var class = window.document.reg.class.value;
var url = "reg.php?user=" + user + "&pass=" + pass + "&email=" + email + "&gender=" + gender + "&type=" + class + "";
loadlink(url);
}
</script>
</head>
TestRegister
<form name='reg' onsubmit='return function1();'>
<table width='98%' style='border: 1px solid black;' valign='top' align='center'>
<tr><td width='30%' style='border: 1px solid black;'>Username</td><td width='70%' style='border: 1px solid black;'><input type="text" name="user"></td></tr>
<tr><td width='30%' style='border: 1px solid black;'>Password</td><td width='70%' style='border: 1px solid black;'><input type="password" name="password"></td></tr>
<tr><td width='30%' style='border: 1px solid black;'>Email</td><td width='70%' style='border: 1px solid black;'><input type="text" name="email"></td></tr>
<tr><td width='30%' style='border: 1px solid black;'>Gender</td><td width='70%' style='border: 1px solid black;'><select name="gender"><option value="Male">Male</option><option

value="Female">Female</option></select></td></tr>
<tr><td width='30%' style='border: 1px solid black;'>Class</td><td width='70%' style='border: 1px solid black;'><select name="class"><option value="Warrior">Path Of Swordsmen</option><option

value="Mage">Guidance Of Magician</option></select></td></tr>
<tr><td width='30%' colspan='2' style='border: 1px solid black;'><input type='submit' name='submit' value='Register!' onclick='function1();'></td></tr>
</table>
</form>
<?php
}
?>

 

If you tried this, it would be successful, but it would say that the username is already registered, so it really lies. Can someone point out the error on this AJAX/PHP?

I did that, and still, the same result, I think it has something to do with my AJAX.

I would print out the query and make sure it contains the expected data.  Check your database for a user entry that's blank.  The script could be losing the username somewhere and trying to insert a blank user, which would be used after the first try.
