Be careful using the alphaNumeric and money validation rules as they require
UTF-8 support for PCRE. On a stock Centos 5 install (or Redhat ES5) I have
PCRE 6.6 06-Feb-2006 compiled in. The following script fails (the
alphaNumeric test from CakePHP 1.2 validation.php):
<?php
$match=preg_match("/^[\p{Ll}\p{Lm}\p{Lo}\p{Lt}\p{Lu}\p{Nd}]+$/mu", "VISA");
if ($match) {
echo "good match!\n";
} else {
echo "bad match!\n";
}
?>
If you don't need UTF-8 alphaNumeric support I recommend a simpler match
expression:
/^[A-Z0-9]+$/
