hey all!
I'm trying to make sure the data inputted from my form is okay. The form includes a 7 checkboxes, all the values can be 1, 2, 3, 4, 5, 6, 7 depending on what the user checks.
Basically I want to form check this incase any loser wants to alter the form and change the checkboxes values. I'm using CGI.pm and not quite sure on how I will check each and every value and untaint them.
heres my code:
our @io = $INPUT->param('io');
if (@io) { #this field is not a required field
foreach $io (@io) {
if ($io =~ /^([0-9,]+)$/ && length($io) < 2) {
$io = $1;
}
else {
print "Do not alter this form. Objective field. Your IP has b
+een logged and will be further investigated.";
die;
}
}
}
Is there a better way to formcheck an array of values or to untaint them?
Thanks!
