I was told that you can't have any HTML output before a header statement, but when I changed my script so my header statements were before the HTML it would no longer work and then I changed it back to the way I had it and it worked. Should I do anything about this?
Here's my script, this is the page that my client is redirected to when they login.
You'll notice at the way bottom i have a header statement that redirects the viewer if the cookie is not found.
<?php
// Connects to your Database
mysql_connect("localhost", "XXXXXX", "XXXXXXX") or die(mysql_error());
mysql_select_db("XXXXX_XXXX") or die(mysql_error());
//checks cookies to make sure they are logged in
if(isset($_COOKIE['ID_my_site']))
{
$username = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
$check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error());
while($info = mysql_fetch_array( $check ))
{
//if the cookie has the wrong password, they are taken to the login page
if ($pass != $info['password'])
{ header("Location: home.php");
}
//otherwise they are shown the admin area
else
{
?>
