Range

Validates that a given number or DateTime object is between some minimum and maximum.

Basic Usage

To verify that the "height" field of a class is between "120" and "180", you might add the following:

  • Annotations
  • YAML
  • XML
  • PHP
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
// src/AppBundle/Entity/Participant.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Participant
{
    /**
     * @Assert\Range(
     *      min = 120,
     *      max = 180,
     *      minMessage = "You must be at least {{ limit }}cm tall to enter",
     *      maxMessage = "You cannot be taller than {{ limit }}cm to enter"
     * )
     */
    protected $height;
}

Date Ranges

This constraint can be used to compare DateTime objects against date ranges. The minimum and maximum date of the range should be given as any date string accepted by the DateTime constructor. For example, you could check that a date must lie within the current year like this:

  • Annotations
  • YAML
  • XML
  • PHP
1
2
3
4
5
6
7
8
9
10
11
12
13

15
// src/AppBundle/Entity/Event.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Event
{
    /**
     * @Assert\Range(
     *      min = "first day of January",
     *      max = "first day of January next year"
     * )
     */
    protected $startDate;
}

Be aware that PHP will use the server's configured timezone to interpret these dates. If you want to fix the timezone, append it to the date string:

  • Annotations
  • YAML
  • XML
  • PHP

// src/AppBundle/Entity/Event.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Event
{
    /**
     * @Assert\Range(
     *      min = "first day of January UTC",
     *      max = "first day of January next year UTC"
     * )
     */
    protected $startDate;
}

The DateTime class also accepts relative dates or times. For example, you can check that a delivery date starts within the next five hours like this:

  • Annotations
  • YAML
  • XML
  • PHP
1
2
3

// src/AppBundle/Entity/Order.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Order
{
    /**
     * @Assert\Range(
     *      min = "now",
     *      max = "+5 hours"
     * )
     */
    protected $deliveryDate;
}

Options

min

type: number or string (date format)

This required option is the "min" value. Validation will fail if the given value is less than this min value.

max

type: number or string (date format)

This required option is the "max" value. Validation will fail if the given value is greater than this max value.

minMessage

type: string default: This value should be {{ limit }} or more.

The message that will be shown if the underlying value is less than the min option.

You can use the following parameters in this message:

Parameter Description
{{ value }} The current (invalid) value
{{ limit }} The lower limit

maxMessage

type: string default: This value should be {{ limit }} or less.

The message that will be shown if the underlying value is more than the max option.

You can use the following parameters in this message:

Parameter Description
{{ value }} The current (invalid) value
{{ limit }} The upper limit

invalidMessage

type: string default: This value should be a valid number.

The message that will be shown if the underlying value is not a number (per the is_numeric PHP function).

You can use the following parameters in this message:

Parameter Description
{{ value }} The current (invalid) value

payload

type: mixed default: null

This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.

For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.

groups

type: array | string

It defines the validation group or groups this constraint belongs to. Read more about validation groups.
