Enums

Since CakePHP 5 you can now use native enums. Just spice it a bit with Tools plugin magic, and all good to go.

Add the EnumOptionsTrait to your enums to have options() method available in your templates etc.

use Tools\Model\Enum\EnumOptionsTrait;

enum UserStatus: int implements EnumLabelInterface {

	use EnumOptionsTrait;

    ...

}

If you now need the options array for some entity-less form, you can use it as such:

echo $this->Form->control('status', ['options' => \App\Model\Enum\UserStatus::options()]);

The same applies if you ever need to narrow down the options (e.g. not display some values as dropdown option), or if you want to resort the options for display:

$options = UserStatus::options([UserStatus::ACTIVE, UserStatus::INACTIVE]);
echo $this->Form->control('status', ['options' => $options]);
