Validators¶

Here are all out of the box available validators shown with their name, a description and, if needed, their parameters.

Basics and Miscellaneous¶

Basic validators and everything else.

boolean¶

Validates if the given value is somehow a boolean one. Those are the accepted values:

true
false
‘true’
‘false’
1
0
‘1’
‘0’
‘on’
‘off’
‘yes’
‘no’

inSet¶

Validates if the value is in the given set.

Parameters

set: an array of valid values

required¶

Validates if there is any value not being null or empty string. Might be one of the most used validators.

or¶

Validator to combine other validators with a logical “or”.

**Attention: The error result of this validator is not just a string, but an array. Example:

$validator = new Validator();
$data = array(
    'a' => 'invalid'
);
$rules = array(
    'a' => array(array('or', $validator, array('email'), array('url')))
);
$result = $validator->isValid($rules, $data);

This results in the following validation result:

$result = array(
    'valid' => false,
    'errors' => array(
        'a' => array(array('or' => array('email', 'url')))
    )
);

Parameters

validator: the Validator or subclass instance which will execute the child validations
rules 1: array of rules to combine; like array(array(‘required’), array(‘between’, 9999, 100000))
rules 2: array of rules to combine; like array(array(‘required’), array(‘between’, 9999, 100000))

You can add as many more rules parameters as you need.

Strings¶

This validators handle strings.

alphabetical¶

alphaNumerical¶

Validates if the given value is alphanumerical meaning it contains only the characters a-z, A-Z and 0-9.

contains¶

Validates if the parameter is within the given value.

Parameters

sub value: the value which must be within the value to validate
case sensitive: boolean value indicating whether the comparsion should be case sensitive; optional, defaults to true

Parameters

regexp: the regular expression to be fulfilled

value¶

Validates if the given parameter is equal to the parameter. Useful for example for terms and conditions checkboxes.

Numerical¶

This validators handle integers and floats.

between¶

Validates if the given value is between two numerical values, but not equal to one of them.

Parameters

min: The lower boundary
max: The upper boundary

floating¶

Validates if the value is in the format of a floating point number.

integer¶

Validates if the value is in the format of an integer number.

max¶

Validates if the given numerical value is maximal the given parameter.

Parameters

max: The maximum

min¶

Validates if the given numerical value is minimal the given parameter.

Parameters

min: The minimum

slug¶

Validates if the given value is a slug meaning it starts with a set of characters (a-z, 0-9) followed by an optional set of dash (-) and more characters (a-z, 0-9). Examples: foo, foo-bar, foo-bar-asd

url¶

Validates if the given parameter is an URL.

Dates and Times¶

This validators handle date times.

afterDateTime¶

Compares the given value to the date time parameter and validates if the value is after it.

Parameters

date time: Date to compare the value to, format: Y-m-d H:i:s
date time format: To override the default date format; optional, defaults to Y-m-d H:i:s

beforeDateTime¶

Compares the given value to the date time parameter and validates if the value is before it.

Parameters

date time format: To override the default date format; optional, defaults to Y-m-d H:i:s

dateTime¶

Validates if the value is in the format of a date time.

Parameters

date time format: To override the default date format; optional, defaults to Y-m-d H:i:s

dateTimeBetween¶

Compares the given value to the date time parameters and validates if the value is between them.

Parameters

date time min: Date time to which the value must be older, format: Y-m-d H:i:s
date time max: Date time to which the value must be younger, format: Y-m-d H:i:s
date time format: To override the default date format; optional, defaults to Y-m-d H:i:s

inTheFuture¶
