<p>我在Symfony/5.4中有这个实体类:</p> <pre class="brush:php;toolbar:false;">use DoctrineORMMapping as ORM; use SymfonyComponentValidatorConstraints as Assert; class Assignments { public const SALARY_RANGES = [ 'Red', 'Green', null, ]; /** * @ORMColumn(length=255, nullable=true) * @AssertChoice(choices=Assignments::SALARY_RANGES, strict=true) */ private ?string $salaryRange; /** * @ORMManyToOne(targetEntity="Employee", inversedBy="assignments") * @ORMJoinColumn(name="employee_id", referencedColumnName="id", onDelete="CASCADE") */ private ?Employee $employee; }</pre> <p>我需要确保如果employee不为空，则salaryRange具有非空值，反之亦然。是否可以使用约束注解来强制实施这一要求?</p> <p>我一直在尝试使用@AssertCallback，但我无法弄清楚如何获取其他字段的值。也许这甚至不是正确的工具。</p> <pre class="brush:php;toolbar:false;">/** * @AssertCallback({"ExampleValidator", "assertEmployeeOnlyCallback"}) */</pre> <pre class="brush:php;toolbar:false;">public static function assertEmployeeOnlyCallback(mixed $data, ExecutionContextInterface $context): void { // `$data` contains value from `salaryRange` but, where is `employee`? }</pre> <p><br /></p>

class Author

    // ...
    private int $field = 1;
    private string $otherField;

    public function validate(ExecutionContextInterface $context, mixed $payload): void
    {
        
        if ($this->field > 1 && $this->otherField != '') {
            $context->buildViolation('Your validation message')
                ->atPath('toherField')
