include ("dbConfig.php");


//Input vaildation and the dbase code
if ( $_GET["op"] == "reg" )
=A0{
=A0$bInputFlag =3D false;
=A0foreach ( $_POST as $field )
=A0 {
=A0 if ($field == "")
   {
   $bInputFlag =3D false;
   }
=A0 else
   {
   $bInputFlag =3D true;
   }
=A0 }
=A0// If we had problems with the input, exit with error
=A0if ($bInputFlag == false)
=A0 {
=A0 die( "Problem with your registration info. "
   ."Please go back and try again.");
=A0 }

=A0// Fields are clear, add user to database
=A0//=A0 Setup query
