Answer 1

I take it by, "redirect a user back after login" you mean to the page they where on before heading to the login page... if so then I'd suggest something like this:

<script>
function goBack() {
    window.history.go(-1);
}
</script>

The function above takes the user back one step in the window/tab's history.

Code tweak:

if ($userEntry == $row_c['pword']  & $email == $row_c['Email'] )
{
   echo"<script>alert('You have been logged in !');goBack()</script>";

or

if ($userEntry == $row_c['pword']  & $email == $row_c['Email'] )
{
   echo"<script>alert('You have been logged in !'); window.history.go(-1) </script>";
