Here's the login form (on login.html):
PHP Code:
<form action="login.php" method="POST" name="frmLogin">
<table border="0" cellspacing="3" cellpadding="2" bgcolor="#999999">
<tr align="center">
<td>
<p>Choose a Username:</p>
</td>
<td>
<p>Choose a Password:</p>
</td>
<td>
<p>Your Email:</p>
</td>
</tr>
<tr align="center">
<td>
<input type="text" name="txtUsername" size="25">
</td>
<td>
<input type="password" name="txtPassword" size="25">
</td>
<td>
<input type="text" name="txtEmail" size="25">
</td>
</tr>
<tr align="center">
<td valign="top"colspan="3"><img src="images/spacer.gif" width="100" height="10"></td>
</tr>
<tr align="center">
<td valign="top"colspan="3"><img src="images/spacer.gif" width="100" height="5"></td>
</tr>
<tr align="center">
<td valign="top"colspan="3">
<input type="submit" name="login" value="Get Started!">
</td>
</tr>
</table>
</form>
and this is login.php:
PHP Code:
<?PHP
//check that the user is calling the page from the login form and not accessing it directly
//and redirect back to the login form if necessary
if (!isset($txtUsername) || !isset($txtPassword))
{
echo '<h3>Username and password not set. <a href="login.html">Go back to login</a>.</h3>';
// header( "Location: login.html" );
exit();
}
//check that the form fields are not empty, and redirect back to the login page if they are
elseif (empty($txtUsername) || empty($txtPassword) || empty($txtEmail))
{
echo '<h3>Username, Password and/or Email missing. Please <a href="login.html">go back</a> and make sure all boxes are filled in.</h3>';
// header( "Location: login.html" );
exit();
}else{
// Add slashes to the username, and make an md5 checksum of the password.
$_POST['user'] = addslashes($_POST['txtUsername']);
$_POST['pass'] = md5($_POST['txtPassword']);
$_POST['email'] = $_POST['txtEmail'];
require("includes/db.php");
$user = mysql_query("SELECT count(id) FROM tbluser WHERE usrUsername='$_POST[user]' AND usrPassword='$_POST[pass]'") or die("<b>Couldn't query the user-database.</b>");
$num = mysql_result($user, 0);
} if (!$num) {
//if nothing is returned by the query, send to New User...
header( "Location: newuser.html" );
exit();
}else{
// Start the login session
session_start();
// Registering the sessions
$_SESSION['user'] = $_POST['user'];
$_SESSION['pass'] = $_POST['pass'];
$_SESSION['email'] = $_POST['email'];
// Set the cookie and redirect
setcookie("InstaWeb", $_SESSION['user']);
// Now we'll make sure the session has been registered
// by redirecting to the checkLogin page, from where
// the user will get redirected to Step One.
header('Location: checkLogin.php');
}
?>
The error message when I try to log in:
Quote: | Username and password not set. Go back to login. |
When I start login.php with
PHP Code:
echo $_POST(txtUsername)'<br>';
echo $_POST(txtPassword)'<br>';
I get a completely blank page!
This seems to mean that the input fields get ignored...
Hope this is clearer
Any ideas? I have searched these forums for similar problems, but found none.
Any help would be greatly appreciated.
Thanks,
Toine
