<p>我在Symfony/5.4中有這個實體類別:</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(長度=255,可為空=true) * @AssertChoice(choices=Assignments::SALARY_RANGES, strict=true)*/ private ?string $salaryRange; /*** @ORMManyToOne（targetEntity =“員工”，inversedBy =“分配”） * @ORMJoinColumn（name =“employee_id”，referencedColumnName =“id”，onDelete =“CASCADE”）*/ private ?Employee $employee; }</pre> <p>我需要確保如果employee不為空，則salaryRange具有非空值，反之亦然。是否可以使用約束註解來強制實施此要求?</p> <p>我一直在嘗試使用@AssertCallback，但我無法弄清楚如何取得其他欄位的值。也許這甚至不是正確的工具。 </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>
