如何比较验证中的日期？

Question

我正在尝试比较验证中的日期.文档说这是可能的,但没有记录.我正在使用注释,我希望一个日期晚于另一个.我该怎么做呢？

Answer 1

我最终使用这样的表达式解决了它:

     /**
     * @var \Datetime
     * @Assert\Type(
     *      type = "\DateTime",
     *      message = "vacancy.date.valid",
     * )
     * @Assert\GreaterThanOrEqual(
     *      value = "today",
     *      message = "vacancy.date.not_today"
     * )
     */
    private $startdate;

    /**
     * @var \Datetime
     * @Assert\Type(
     *      type = "\DateTime",
     *      message = "vacancy.date.valid",
     * )
     * @Assert\GreaterThanOrEqual(
     *      value = "today",
     *      message = "vacancy.date.not_today"
     * )
     * @Assert\Expression(
     *     "this.getEnddate() >= this.getStartdate()",
     *     message="vacancy.date.not_more_than"
     * )
     */
    private $enddate;
