Range ¶
Validates that a given number or DateTime
object is between some minimum and maximum.
Applies to | property or method |

Basic Usage ¶
To verify that the height
field of a class is between 120
and 180
,
you might add the following:
-
Attributes
属性
-
YAML

-
XML

PHP
PHP
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
// src/Entity/Participant.php
namespace App\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Participant
{
#[Assert\Range(
min: 120,
max: 180,
notInRangeMessage: 'You must be between {{ min }}cm and {{ max }}cm tall 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:
-
Attributes
属性
-
YAML
YAML
-
XML
XML

PHP
PHP
1 2 3 4 5 6 7 8 9 10 11 12 13 |
// src/Entity/Event.php
namespace App\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:
-

PHP
1 2 3 4 5 6 7 8 9 10 11 12 13 |
// src/Entity/Event.php
namespace App\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:
-
Attributes
属性
-
YAML
YAML

XML
-

PHP

// src/Entity/Order.php
namespace App\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Order
{
#[Assert\Range(
min: 'now',
max: '+5 hours',
)]
protected $deliveryDate;
}

Options ¶
groups
¶
type: array
| string
It defines the validation group or groups of this constraint. Read more about validation groups.
invalidDateTimeMessage
¶
type: string
default: This value should be a valid number.
The message displayed when the min
and max
values are PHP datetimes but
the given value is not.
You can use the following parameters in this message:
Parameter | Description |
---|---|
{{ value }} |
The current (invalid) value |
invalidMessage
¶
type: string
default: This value should be a valid number.
The message displayed when the min
and max
values are numeric (per
the is_numeric PHP function) but the given value is not.
You can use the following parameters in this message:
Parameter | Description |
---|---|
{{ value }} |
The current (invalid) value |
{{ label }} |
Corresponding form field label |
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.
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, and no min option has been defined (if both are defined, use notInRangeMessage).
You can use the following parameters in this message:
Parameter | Description |
---|---|
{{ limit }} |
The upper limit |
{{ value }} |
The current (invalid) value |
maxPropertyPath
¶
type: string
It defines the object property whose value is used as max
option.
For example, if you want to compare the $submittedDate
property of some object
with regard to the $deadline
property of the same object, use
maxPropertyPath="deadline"
in the range constraint of $submittedDate
.
Tip
When using this option, its value is available in error messages as the
{{ max_limit_path }}
placeholder. Although it's not intended to
include it in the error messages displayed to end users, it's useful when
using APIs for doing any mapping logic on client-side.
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.
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, and no max option has been defined (if both are defined, use notInRangeMessage).
You can use the following parameters in this message:
Parameter | Description |
---|---|
{{ limit }} |
The lower limit |
{{ value }} |
The current (invalid) value |
minPropertyPath
¶
type: string
It defines the object property whose value is used as min
option.
For example, if you want to compare the $endDate
property of some object
with regard to the $startDate
property of the same object, use
minPropertyPath="startDate"
in the range constraint of $endDate
.
Tip
When using this option, its value is available in error messages as the
{{ min_limit_path }}
placeholder. Although it's not intended to
include it in the error messages displayed to end users, it's useful when
using APIs for doing any mapping logic on client-side.
notInRangeMessage
¶
type: string
default: This value should be between {{ min }} and {{ max }}.
The message that will be shown if the underlying value is less than the min option or greater than the max option.
You can use the following parameters in this message:
Parameter | Description |
---|---|
{{ max }} |
The upper limit |
{{ min }} |
The lower limit |
{{ 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.
