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

use Symfony\Component\Validator\Constraints as Assert;

class File
{
    /**
     * @Assert\Ulid
     */
    protected $identifier;
}

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 this constraint belongs to. Read more about validation groups.

message

type: string default: This is not a valid ULID.

This message is shown if the string is not a valid ULID.

You can use the following parameters in this message:

Parameter Description
{{ value }} The current (invalid) value
{{ label }} Corresponding form field label

normalizer

type: a PHP callable default: null

This option allows to define the PHP callable applied to the given value before checking if it is valid.

For example, you may want to pass the 'trim' string to apply the trim PHP function in order to ignore leading and trailing whitespace during validation.

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.
