Array of enums not supported

[ThomasLandauer]

doctrine/orm 2.12.0 now supports arrays of enums, see doctrine/orm#9497

This is the syntax:

#[ORM\Column(type: Types::SIMPLE_ARRAY, length: 255, nullable: true, enumType: Foo::class)]
private array $foo = [];

phpstan is reporting:

Property App\Entity\User::$foo type mapping mismatch: backing type string of enum App\Enum\Foo does not match database type array.
Property App\Entity\User::$foo type mapping mismatch: database can contain App\Enum\Foo|null but property expects array.
Property App\Entity\User::$foo type mapping mismatch: property can contain array but database expects App\Enum\Foo|null.

I have the same problem

Same problem here on doctrine/orm 2.14.1

It also applies to other types:

/**
 * @var ViewSettingsEnum[]
 */
#[ORM\Column(type: 'json', nullable: true, enumType: ViewSettingsEnum::class)]
private ?array $viewSettings = null;

results in

Still present with doctrine/orm 3.1.3

[ServerExe]

Still present on doctrine/orm 3.2.0

[psprokofiev]

Still present...

"doctrine/orm": "3.2.1",
"phpstan/phpstan": "1.11.17",
"phpstan/phpstan-doctrine": "1.4.5",

[stof]

should be fixed by #605 (except that the case described in the initial issue is affected by #436 as well, which is unrelated to enums)

[jeffreymoelands]

Is it correct that only simple_array is supported and json isn't?

[stof]

Any DBAL type mapping to a PHP array is supported.
The json type will still report a type mismatch error because the DBAL type does not match to a PHP array (strings, numbers and booleans are also valid JSON values)

Still present with doctrine/orm 3.2.2 while "handling" a form

[ondrejmirtes]

@Legendary4226 This is a closed and fixed issue. If you have any problems, open a new issue and describe your problem in full detail.

[ServerExe]

Issue was fixed but a new one appeared which I can't fully understand. My previously ignored error:

Property App\Entity\EmailTemplate::$emailBccAddresses type mapping mismatch: backing type string of enum App\Enum\EmailBccAddress does not match database type array|bool|float|int|JsonSerializable|stdClass|string|null.

was replaced by

Property App\Entity\EmailTemplate::$emailBccAddresses type mapping mismatch: backing type string of enum App\Enum\EmailBccAddress does not match value type mixed of the database type array|bool|float|int|JsonSerializable|stdClass|string|null.

This is my entity property:

/**
 * @var EmailBccAddress[]|null
 */
#[ORM\Column(type: 'json', nullable: true, enumType: EmailBccAddress::class)]
private ?array $emailBccAddresses = null;

This is my Enum:

<?php
declare(strict_types=1);

namespace App\Enum;

enum EmailBccAddress: string
{
    case MY_VALUE = 'my_value';
}

[stof]

@ServerExe the type json does not guarantee that the data will be an array of strings (nor a string). That's why this error is reported. The database value could be a string, a boolean, a number, or an array of those.

[ServerExe]

I see. Sorry, I missed your comment at the top where you already described it! My bad. So, best solution would be to pick simple_array for that.

The only thing I am afraid of is: If enum types contain a comma in their string, this could break Doctrines simple_array logic because values are separated via comma in the column. That's the reason I chose JSON
