I would share the source to add the "codice fiscale validation" into your form...this can be useful to italian to add the Codice Fiscale field in registration form.

Add this function in /components/helpers/validation.php:
function CodiceFiscale($param,$extra=null){
if( $param == '' ) return false;
if( strlen($param) != 16 )
return false;
$param = strtoupper($param);
if( ! ereg("^[A-Z0-9]+$", $param) ){
return false;
}
$s = 0;
for( $i = 1; $i <= 13; $i += 2 ){
$c = $param[$i];
if( '0' <= $c && $c <= '9' )
$s += ord($c) - ord('0');
else
$s += ord($c) - ord('A');
}
for( $i = 0; $i <= 14; $i += 2 ){
$c = $param[$i];
switch( $c ){
case '0': $s += 1; break;
case '1': $s += 0; break;
case '2': $s += 5; break;
case '3': $s += 7; break;
case '4': $s += 9; break;
case '5': $s += 13; break;
case '6': $s += 15; break;
case '7': $s += 17; break;
case '8': $s += 19; break;
case '9': $s += 21; break;
case 'A': $s += 1; break;
case 'B': $s += 0; break;
case 'C': $s += 5; break;
case 'D': $s += 7; break;
case 'E': $s += 9; break;
case 'F': $s += 13; break;
case 'G': $s += 15; break;
case 'H': $s += 17; break;
case 'I': $s += 19; break;
case 'J': $s += 21; break;
case 'K': $s += 2; break;
case 'L': $s += 4; break;
case 'M': $s += 18; break;
case 'N': $s += 20; break;
case 'O': $s += 11; break;
case 'P': $s += 3; break;
case 'Q': $s += 6; break;
case 'R': $s += 8; break;
case 'S': $s += 12; break;
case 'T': $s += 14; break;
case 'U': $s += 16; break;
case 'V': $s += 10; break;
case 'W': $s += 22; break;
case 'X': $s += 25; break;
case 'Y': $s += 24; break;
case 'Z': $s += 23; break;
}
}
if( chr($s%26 + ord('A')) != $param[15] )
return false;
return true;
}
