Time

Warning: You are browsing the documentation for Symfony 6.0, which is no longer maintained.

Read the updated version of this page for Symfony 7.2 (the current stable version).

Time

Validates that a value is a valid time, meaning a string (or an object that can be cast into a string) that follows a valid HH:MM:SS format.

Applies to	property or method
Class	Time
Validator	TimeValidator

Basic Usage

Suppose you have an Event class, with a startsAt field that is the time of the day when the event starts:

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

use Symfony\Component\Validator\Constraints as Assert;

class Event
{
    /**
     * @var string A "H:i:s" formatted value
     */
    #[Assert\Time]
    protected $startsAt;
}

use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Mapping\ClassMetadata;

class Event
{
   /**

    */
    protected $startsAt;

    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('startsAt', new Assert\Time());
    }
}
    

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

`groups`

type: array | string

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

`message`

type: string default: This value is not a valid time.

This message is shown if the underlying data is not a valid time.

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.
