If regular expressions aren't your thing - don't use regular expressions =)
e.g. write a validation function like so:
function validateTime($check) {
$string = current($check);
list($mins, $seconds) = expode(':', $string);
$validMins = is_numeric($mins);
$validSeconds = is_numeric($seconds) && ($seconds < 60);
return $validMins && $validSeconds;
}
Alternatively since a regex is not cakephp specific - ask in an appropriate
place (stack overflow) with appropriate context i.e. "how can I check that
a string matches the format xx:yy where <it's time>?" Or - check for
existing questions asking exactly that, like this
one: http://stackoverflow.com/questions/3964972/validate-this-format-hhmm
and modify to your needs
