Basic Usage ¶
Suppose you have a UserSettings
class, with a timezone
field that is a
string which contains any of the PHP timezone identifiers (e.g. America/New_York
):

class UserSettings
{
#[Assert\Timezone]
protected $timezone;
}

Note
As with most of the other constraints, null
and empty strings are
considered valid values. This is to allow them to be optional values.
If the value is mandatory, a common solution is to combine this constraint
with NotBlank.
Options ¶
countryCode
¶
type: string
default: null
If the zone
option is set to \DateTimeZone::PER_COUNTRY
, this option
restricts the valid timezone identifiers to the ones that belong to the given
country.
The value of this option must be a valid ISO 3166-1 alpha-2 country code
(e.g. CN
for China).
groups
¶
type: array
| string
It defines the validation group or groups of this constraint. Read more about validation groups.
intlCompatible
¶
type: boolean
default: false
This constraint considers valid both the PHP timezone identifiers and the ICU timezones provided by Symfony's Intl component
However, the timezones provided by the Intl component can be different from the
timezones provided by PHP's Intl extension (because they use different ICU
versions). If this option is set to true
, this constraint only considers
valid the values compatible with the PHP \IntlTimeZone::createTimeZone()
method.
message
¶
type: string
default: This value is not a valid timezone.
This message is shown if the underlying data is not a valid timezone identifier.
You can use the following parameters in this message:
Parameter | Description |
---|---|
{{ value }} |
The current (invalid) value |
{{ label }} |
Corresponding form field label |
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.
zone
¶
type: string
default: \DateTimeZone::ALL
Set this option to any of the following constants to restrict the valid timezone identifiers to the ones that belong to that geographical zone:
\DateTimeZone::AFRICA
\DateTimeZone::アフリカ\DateTimeZone::AMERICA
\DateTimeZone::アメリカ\DateTimeZone::ANTARCTICA
\DateTimeZone::南極大陸\DateTimeZone::ARCTIC
\DateTimeZone::北極\DateTimeZone::ASIA
\DateTimeZone::アジア\DateTimeZone::ATLANTIC
\DateTimeZone::アトランティック\DateTimeZone::AUSTRALIA
\DateTimeZone::オーストラリア\DateTimeZone::EUROPE
\DateTimeZone::ヨーロッパ\DateTimeZone::INDIAN
\DateTimeZone::INDIAN\DateTimeZone::PACIFIC
\DateTimeZone::太平洋
In addition, there are some special zone values:
\DateTimeZone::ALL
accepts any timezone excluding deprecated timezones;\DateTimeZone::ALL は非推奨のタイムゾーンを除くすべてのタイムゾーンを受け入れます。\DateTimeZone::ALL_WITH_BC
accepts any timezone including deprecated timezones;\DateTimeZone::ALL_WITH_BC 非推奨のタイムゾーンを含むすべてのタイムゾーンを受け入れます。\DateTimeZone::PER_COUNTRY
restricts the valid timezones to a certain country (which is defined using thecountryCode
option).\DateTimeZone::PER_COUNTRY は、有効なタイムゾーンを特定の国 (countryCode オプションを使用して定義) に制限します。
