Well a rather simple solution is:
$R_Check=mysql_query("select email from table where email='$email' and
password='$password'");
if(mysql_num_rows($R_Check)) { header("Location: log_in.php"); }
else
{
$Error="";
$R_Check=mysql_query("select email from table where email='$email'");
if(mysql_num_rows($R_Check)) { $Error="Email exists!\n"; }
$R_Check=mysql_query("select password from table where
password='$password");
if(mysql_num_rows($R_Check)) { $Error.="Password exists!\n"; }
if($Error) { header("Location: not_logged_in.php?error=$Error"); }
else
{
// Add info to DB here
// redirect with header() to proper page
}
}
I wrote this from the top of my head so it might not be the best solution,
or free from bugs for that matter 8), but it should give you a few pointers.
You can turn this into a function to make it easier to maintain and use in
multiple pages.
Hope it helps.
