LessThanOrEqual

2.3

The LessThanOrEqual constraint was introduced in Symfony 2.3.

Validates that a value is less than or equal to another value, defined in the options. To force that a value is less than another value, see LessThan.

Applies to property or method
Options
Class LessThanOrEqual
Validator LessThanOrEqualValidator

Basic Usage

The following constraints ensure that:

  • the number of siblings of a Person is less than or equal to 5
  • the age is less than or equal to 80
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
// src/AppBundle/Entity/Person.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Person
{
    /**
     * @Assert\LessThanOrEqual(5)
     */
    protected $siblings;

    /**
     * @Assert\LessThanOrEqual(
     *     value = 80
     * )
     */
    protected $age;
}

Comparing Dates

This constraint can be used to compare DateTime objects against any date string accepted by the DateTime constructor. For example, you could check that a date must be today or in the past like this:

1
2
3
4
5
6
7
8
9
10
11
12
// src/AppBundle/Entity/Person.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Person
{
    /**
     * @Assert\LessThanOrEqual("today")
     */
    protected $age;
}

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:

1
2
3
4
5
6
7
8
9
10
11
12
// src/AppBundle/Entity/Person.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Person
{
    /**
     * @Assert\LessThanOrEqual("today UTC")
     */
    protected $age;
}

The DateTime class also accepts relative dates or times. For example, you can check that a person must be at least 18 years old like this:

1
2
3
4
5
6
7
8
9
10
11
12
// src/AppBundle/Entity/Person.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Person
{
    /**
     * @Assert\LessThanOrEqual("-18 years")
     */
    protected $age;
}

Options

value

type: mixed [default option]

This option is required. It defines the value to compare to. It can be a string, number or object.

message

type: string default: This value should be less than or equal to {{ compared_value }}.

This is the message that will be shown if the value is not less than or equal to the comparison value.

You can use the following parameters in this message:

Parameter Description
{{ value }} The current (invalid) value
{{ compared_value }} The upper limit
{{ compared_value_type }} The expected value type

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.
