I would just create a custom validation function:
/**
* function intRange
*
* Checks if a value is an integer within the
* range given (inclusive)
*
* @param $value to be checked
* @param $start of range
* @param $end of range
* @return bool
*/
function intRange($value,$start,$end) {
// Verify the value is an int
if (!is_int($value)) return false;
// Verify the value is within the range
if ($value<$start) return false;
if ($value>$end) return false;
// Passed all tests
return true;
}
use it in your validation array like this:
'hour' => array(
'rule' => array('intRange', 0, 23),
'message' => 'Please enter an integer between 0 and 23'
)
