Navegando por la grandiosa red encontre un buen tutorial para hacer un sistema de users,pero quiero añadirle la opcion de ID y mas cosas ;)
Mi problema es que cuando modifico la tabla de la base de datos me da error al registrarme y me dice que no me ha podido registrar:(
Aqui esta el codigo de registro:
Código PHP:
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body bgcolor="#FFFFFF" text="#000000">
<?
session_start();
include("database.php");
function usernameTaken($username){
global $conn;
if(!get_magic_quotes_gpc()){
$username = addslashes($username);
}
$q = "select username from users where username = '$username'";
$result = mysql_query($q,$conn);
return (mysql_numrows($result) > 0);
}
function addNewUser($username, $password){
global $conn;
$q = "INSERT INTO users VALUES ('$username', '$password')";
return mysql_query($q,$conn);
}
function displayStatus(){
$uname = $_SESSION['reguname'];
if($_SESSION['regresult']){
?>
<h1>Registered!</h1>
<p>Thank you <b><? echo $uname; ?></b>, your information has been added to the database, you may now <a href="main.php" title="Login">log in</a>.</p>
<?
}
else{
?>
<h1>Registration Failed</h1>
<p>We're sorry, but an error has occurred and your registration for the username <b><? echo $uname; ?></b>, could not be completed.<br>
Please try again at a later time.</p>
<?
}
unset($_SESSION['reguname']);
unset($_SESSION['registered']);
unset($_SESSION['regresult']);
}
if(isset($_SESSION['registered'])){
?>
<html>
<title>Registration Page</title>
<body>
<? displayStatus(); ?>
</body>
</html>
<?
return;
}
if(isset($_POST['subjoin'])){
if(!$_POST['user'] || !$_POST['pass']){
die('You didn\'t fill in a required field.');
}
$_POST['user'] = trim($_POST['user']);
if(strlen($_POST['user']) > 30){
die("Sorry, the username is longer than 30 characters, please shorten it.");
}
if(usernameTaken($_POST['user'])){
$use = $_POST['user'];
die("Sorry, the username: <strong>$use</strong> is already taken, please pick another one.");
}
$md5pass = md5($_POST['pass']);
$_SESSION['reguname'] = $_POST['user'];
$_SESSION['regresult'] = addNewUser($_POST['user'], $md5pass);
$_SESSION['registered'] = true;
echo "<meta http-equiv=\"Refresh\" content=\"0;url=$HTTP_SERVER_VARS[PHP_SELF]\">";
return;
}
else{
?>
<html>
<title>Registration Page</title>
<body>
<h1>Register</h1>
<form action="<? echo $HTTP_SERVER_VARS['PHP_SELF']; ?>" method="post">
<table align="left" border="0" cellspacing="0" cellpadding="3">
<tr><td>Username:</td><td><input type="text" name="user" maxlength="30"></td></tr>
<tr><td>Password:</td><td><input type="password" name="pass" maxlength="30"></td></tr>
<tr><td colspan="2" align="right"><input type="submit" name="subjoin" value="Join!"></td></tr>
</table>
</form>
</body>
</html>
<?
}
?>
</body>
</html> Código PHP:
CREATE TABLE users (
username varchar(30),
password varchar(32));
Código PHP:
CREATE TABLE users (
id bigint(7) NOT NULL auto_increment,
username varchar(30),
password varchar(32),
yahoo char(100) NOT NULL,
MSN char(100) NOT NULL,
avatar char(100) NOT NULL,
