Hi all
I am new to codecharge studio 2.3. I am trying to get codecharge to validate
a credit card number. The code I have tried does not seem to work or I am
putting it in the wrong place The code is as follows:
// MOD 10 checks
function check_number( $cardnumber ) {
$dig = toCharArray($cardnumber);
$numdig = sizeof ($dig);
$j = 0;
for ($i=($numdig-2); $i>=0; $i-=2){
$dbl[$j] = $dig[$i] * 2;
$j++;
}
$dblsz = sizeof($dbl);
$validate =0;
for ($i=0;$i<$dblsz;$i++){
$add = toCharArray($dbl[$i]);
for ($j=0;$j<sizeof($add);$j++){
$validate += $add[$j];
}
$add = '';
}
for ($i=($numdig-1); $i>=0; $i-=2){
$validate += $dig[$i];
}
if (substr($validate, -1, 1) == '0') { return 1; }
else { return 0; }
}
Please help.
Thanks
Peter

You don't have CCS 3.1 or 3.2?
