between:

Arguments: <digit>,<digit>

The constraint has different implementations based on the value type.

• If the value has a date constraint (date, datetime or datetime_format), the <digit> arguments accepts now DateTime allowed formats. The value must be between than the supplied <digit> arguments. More information in the Symfony Validation documentation.
• If the value has a numeric constraint (integer or float), it must lie between the two values.
• Otherwise, the length of the value must be between the supplied values.

Example:

• string must have minimum length of 2 and maximum length of 6: between:2,6
• integer must have a value between 2 and 6 or less: integer|between:2,6
• date must be between 2010-01-01 and 2011-01-01: date|between:2010-01-01,2011-01-01

boolean

The value must be bool or castable to bool.

• allowed true values: 1, '1', 'on', true
• allowed false values: 0, '0', 'off', false

Note: can also be written as bool

date

The value must be a valid date of format Y-m-d

datetime

The value must be a valid date+time of format Y-m-d H:i:s

date_format

Argument: <pattern>

The value must match the given date pattern. See DateTime::createFromFormat() for formatting options.

email

in

Arguments: string,string,...

The field under validation must be included in the given list of values.

Example:

required|in:foo,bar

integer

The value must be an integer or castable to int.

• example of allowed values: 1, -1, '1', '-1'

Note: can also be written as int

max:

Argument: <digit>

The constraint has different implementations based on the value type.

• If the value has a date constraint (date, datetime or datetime_format), the <digit> argument accepts now DateTime allowed formats and the value must be less or equal than the supplied argument. More information in the Symfony Validation documentation.
• If the value has a numeric constraint (integer or float), it must be smaller than the supplied value.
• Otherwise, the length of the value must be smaller than the supplied value.

Example:

• string with maximum length of 6: max:6
• integer which has to be 6 or less: integer|max:6
• limit the given date by: date|max:+10 days

min

Argument: <value>

The constraint has different implementations based on the value type.

• If the value has a date constraint (date, datetime or datetime_format), the <digit> argument accepts now DateTime allowed formats and the value must be greater or equal than the supplied <digit> argument. More information in the Symfony Validation documentation.
• If the value has a numeric constraint (integer or float), it must be bigger than the supplied value.
• Otherwise, the length of the value must be bigger than the supplied value.

Example:

• string with minimum length of 6: min:6
• integer which has to be 6 or higher: integer|min:6
• limit the given date by: date|min:now

nullable

The value can be null.

regex

Argument: <pattern>

The value must match the supplied regex. The full string will be passed to the preg_match function.

Example:

• match all strings starting with 'ab': regex:/^ab.*$/

required

By default in a data set a key/value-pair can be left out. Add required to make the key/value-pair mandatory.

Example:

[
    'a' => 'required|string',
    'b' => 'integer'
]

Passes:

['a' => 'a'];

Fails:

['b' => '1'];

string

The value must be a string.

url

The value must be a valid url.
