You have to have the ; after
$_SESSION['valid_user'] = $Email

That is why you are getting the error message. Then you can troubleshoot the blank page

Trying my code again

session_start();

if (isset($_POST['Email']) && isset($_POST['password']))
{
$Email = $_POST['Email'];
$password = $_POST['password'];

$conn = mysql_connect (”localhost”, “bollaoil_custome”, “92remotsuc21″) or die(’Cannot connect to the database because: ‘ . mysql_error());
mysql_select_db (”bollaoil_Customers”);

$sql = mysql_query(”select count(*) from customers
where Email = ‘$Email’ and Password = sha1(’$password’)”) or die(mysql_error());

$results = mysql_result($sql, “0″);

if ($results == 0){
header( ‘Location:loginfailed.php’);
}
else
{
$_SESSION['valid_user'] = $Email
header( ‘Location:http://www.kingscarcare.com/beta1/coupon.php’);
}

I’ve used your site before with great results. Now I’m trying to do this and have scoured my code a dozen times but cannot find why I’m getting this error:

Parse error: syntax error, unexpected T_STRING in cauthenticate.php on line 24

This is my code:

Line 24 of my code is
header( ‘Location:http://www.kingscarcare.com/beta1/coupon.php’);

I have the semi-colon in place and I’ve triple checked all my brackets and quotes to see if one was left open. I can’t find the error, can you help!?

Thanks for sharing. I’ve concerns about mysql_real_escape_string and authentication and try to find if it’s essential to use it. I’ve found something but it’s in french, but the code includes mysql_real_escape_string:

Thanks for any help.
