I'm creating a login page for my database and I was wondering how I can use an if statement or whatever I need to get to my next page based on the password user and password entered.


if ($_POST['uname'] === 'user' && $_POST['password'] === 'pass')
{
echo "worked";
} else {
echo "Sorry, wrong username / password";
}


Now I know that works. Problem is, I need to change the echo "worked"; to gotourl (userpage1.php); and gotourl obviously isn't a way to do it. I've tried sending headers but it always tells me they have already been sent. I've checked for whitespace and everything because I read that it can be an issue. There is no whitespace at the end or beginning so I'm completely clueless. HELP

Headers will work if you put the code BEFORE any HTML is outputted.

Output buffering will prevent the header already sent error. And I would use exit() right after the header() function


header code
<?php
ob_start();
?>

footer code
<?php
ob_end_flush();
?>

Didn't work. My new code:

<?php
if ($_POST['uname'] === 'user' && $_POST['password'] === 'pass')
{
header('http://www.google.com');
} else {
die;
}
?>

<html
<head>
<title>My page</title>
</head>

<body>
</body>
</html>

Did nothing. Just sits on a white page. I passed the uname and pass variables from a form on the previous page.

header('http://www.google.com');

Should be:

header ("Location: http://www.google.com");

header('http://www.google.com');

Should be:

header ("Location: http://www.google.com");

Thanks! I decided I'd use the following. I found another post about 5 seconds before you posted. Thanks for the help though! Now I can get this crazy script off the ground. Now time to reference some places and make a table displaying prospects. This should be fun... Advice? I didn't get much help in my other thread just got pointed at a tutorial.


<?php
$url = "http://www.google.com";
if ($_POST['uname'] === 'user' && $_POST['password'] === 'pass')
{
header("location: $url");
} else {
die;
}
?>

Ya as stated you need Location, I assumed you had the header code already correct!
