Question

This is the regular expression I am using:

if (preg_match("/^[0-9]{1,2}\/[0-9]{1,2}\/[0-9]{4}$/", $_POST["collection-date"]) === 0) {
        $errors .= "\n Error: Invalid Collection Date";
        $collectiondate = FALSE;
    }

Currently $_POST['collection-date'] equals 15/02/2012 and it still returns false. Why is this?

Thank you for any suggestions.

Answer 1

$split = explode('/', $date);
if (!isset($split[2]) || !checkdate($split[1],$split[0],$split[2])) {
    $errors .= "\n Error: Invalid Collection Date";
    $collectiondate = FALSE;
}

This also validates false if someone enters an invalid date, such as 99/99/2012 or 31/02/2012, which you probably want as well.
