  • {boolean} required - Short-cut for optional=false and empty=false. Note that if this option is set the optional and empty parameters are automatically set and cannot be overridden by passing in different values.
  • {string} message - Error message shown should validation fail. This provides complete control over the message shown to the end user, including internationalisation (i.e. to provide a translation that is not in the English language).
    • Namespace: DataTables\Editor
    Example: 
    // Ensure that a non-empty value is given for a field
     Field::inst( 'engine' )->validator( Validate::required() )

    Example: 
    // Don't require a field to be submitted, but if it is submitted, it
     // must be non-empty
     Field::inst( 'reg_date' )->validator( Validate::notEmpty() )

    Example: 
    // Date validation
     Field::inst( 'reg_date' )->validator( Validate::dateFormat( 'D, d M y' ) )

    Example: 
    // Date validation with a custom error message
     Field::inst( 'reg_date' )->validator( Validate::dateFormat( 'D, d M y',
         ValidateOptions::inst()
             ->message( 'Invalid date' )
     ) )

    Example: 
    // Require a non-empty e-mail address
     Field::inst( 'reg_date' )->validator( Validate::email( ValidateOptions::inst()
       ->empty( false )
     ) )

    Example: 
    // Custom validation - closure
     Field::inst( 'engine' )->validator( function($val, $data, $opts) {
        if ( ! preg_match( '/^1/', $val ) ) {
          return "Value <b>must</b> start with a 1";
        }
        return true;

    Methods summary
    public static callable
    # none( )

    No validation - all inputs are valid.
    public static string|true
    # basic( string $cfg = null , array $opts,…, array $host,… )

    Basic validation - this is used to perform the validation provided by the validation options only. If the validation options pass (e.g. required, empty and optional) then the validation will pass regardless of the actual value.
    public static string|true
    # required( string $cfg = null , array $opts,…, array $host,… )

    Required field - there must be a value and it must be a non-empty value
    public static callable
    # notEmpty( DataTables\Editor\ValidateOptions $cfg = null )

    Optional field, but if given there must be a non-empty value
    public static string|true
    # boolean( string $cfg = null , array $opts,…, array $host,… )

    Validate an input as a boolean value.
    public static string|true
    # numeric( string $decimal = ".", string[] $cfg = null , array $opts,…, array $host,… )

    Check that any input is numeric.
    public static string|true
    # minNum( string $min, string[] $decimal = ".", integer|array $cfg = null , array $host,… )

    Check for a numeric input and that it is greater than a given value.
    public static string|true
    # maxNum( string $max, string[] $decimal = ".", integer|array $cfg = null , array $host,… )

    Check for a numeric input and that it is less than a given value.
    public static string|true
    # minMaxNum( string $min, string[] $max, integer|array $decimal = '.', array $cfg = null )

    Check for a numeric input and that it is both greater and smaller than given numbers.
    public static string|true
    # email( string $cfg = null , array $opts,…, array $host,… )

    Validate an input as an e-mail address.
    public static string|true
    # minLen( string $min, string[] $cfg = null , integer|array $opts,…, array $host,… )

    Validate a string has a minimum length.
    public static string|true
    # maxLen( string $max, string[] $cfg = null , integer|array $opts,…, array $host,… )

    Validate a string does not exceed a maximum length.
    public static string|true
    # minMaxLen( string $min, string[] $max, integer|array $cfg = null , array $host,… )

    Require a string with a certain minimum or maximum number of characters.
    public static string|true
    # ip( string $cfg = null , array $opts,…, array $host,… )

    Validate as an IP address.
    public static string|true
    # url( string $cfg = null , array $opts,…, array $host,… )

    Validate as an URL address.
    public static string|true
    # xss( string $cfg = null , integer|array $opts,…, array $host,… )

    Check if string could contain an XSS attack string
    public static string|true
    # values( string $values, string[] $cfg = null , integer|array $opts,…, array $host,… )

    Confirm that the value submitted is in a list of allowable values
    public static string|true
    # noTags( string $cfg = null , integer|array $opts,…, array $host,… )

    Check if there are any tags in the submitted value
    public static string|true
    # dateFormat( string $format, string[] $cfg = null , array|string $opts,…, array $host,… )

    Check that a valid date input is given
    public static string|true
    # unique( string $cfg = null, string[] $column = null, integer|array $table = null, array $db = null )

    Check that the given value is unique in the database
    public static string|true
    # dbValues( string $cfg = null, string[] $column = null, integer|array $table = null, array $db = null, $values = array() )

    Check that the given value is a value that is available in a database - i.e. a join primary key. This will attempt to automatically use the table name and value column from the field's options method (under the assumption that it will typically be used with a joined field), but the table and field can also be specified via the options.
