How to compare dates in validation?

Question

I'm trying to compare dates in my validation. The documentation says it's possible but It's not documented. I'm using annotations and I want one date to be later that the other. How do I do this?

Answer 1

I've eventually solved it using expressions like so:

     /**
     * @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;
