l IsNonEmpty - Checks that the value is a non-empty string (length non-zero and not all whitespace), or a nonempty array. l IsNonNegative - Checks that the value is numeric and non-negative. l IsRegexMatch - Checks that the value matches a regular expression supplied as the argument the validator. The regular expression should be a Perl-compatible regular expression with delimiters. For example, the validator argument /^a/i will match any value that starts with an "a", case-insensitively. "Regular Expressions" on page 305 for more information about regular expression syntax. l IsValidBool - Checks that the value is a standard Boolean truth value. Valid Boolean values are the integers 0 and 1 and the PHP values false and true. l IsValidDateTime - Checks that the value appears to be a valid time specification string according to the rules of the PHP function strtotime(). Valid date/time syntax includes ISO 8601 standard times (YYYY-MM-DD hh:mm:ss) with and without time zone specifications, as well as many other formats. l IsValidEmail - Checks that the value appears to be a valid RFC 822-compliant email address. When using the IsValidEmail validator, the validator argument may be specified with a whitelist/blacklist of domain names. Use the syntax: array( 'allow' => array( 'corp-domain.com', 'other-domain.com', ), 'deny' => array( 'blocked-domain.com', 'other-blocked-domain.com', ), ) n The keys 'whitelist' and 'blacklist' may also be used for 'allow' and 'deny', respectively. n An 'allow' or 'deny' value that is a string is converted to a single element array. n Wildcard matching may be used on domain names: the prefix '*.' means match any domain that ends with the given suffix. A '*' component can also be used inside the hostname, and will match zero or more domain name components. n If the 'allow' list is empty or unset, the default behavior is to accept ALL domains other than those listed in the 'deny' list. n If the 'deny' list is empty or unset, the default behavior is to deny ALL domains other than those listed in the 'allow' list. n If both 'allow' and 'deny' lists are provided, the default behavior is to accept a domain name that does not match any of the patterns provided. The 'allow' list is checked first, followed by 'deny'. To obtain the opposite behavior, specify the wildcard '*' as the last entry in the 'deny' list. l IsValidFileUpload - Checks that the value is a file upload. l IsValidFutureDateTime - Checks that the value is a valid time specification string according to the rules of the PHP function strtotime(), and that the time specification refers to a point in the future. l IsValidFutureTimestamp - Checks that the value is a valid UNIX time referring to a point in the future. l IsValidHostname - Checks that the value is a valid IP address or a hostname that resolves to an IP address. l IsValidHostnameCidr - Checks that the value is a valid IP address or hostname, which may also have an optional /N suffix indicating the network prefix length in bits (CIDR notation). l IsValidHostnamePort - Checks that the value is a valid IP address or hostname, which may optionally include a port number specified with the syntax hostname:port. l IsValidIpAddr - Checks that the value is a valid IP address.
