如何在symfony 2 php中访问注释中的类变量和常量

Question

我有一个这样的课程：

Warning messages:
1: In `[.data.table`(demographic1, , `:=`(paste0("F", i),  ... :
RHS 1 is length 2 (greater than the size (1) of group 1). The last 1    element(s) will be discarded.

我必须对值class Student { const GENDER_MALE = "male", GENDER_FEMALE = "female"; /** * @var string $gender * * @ORM\Column(name="gender", type="string", length=50,nullable=false) * @Assert\NotBlank(message="Gender cannot be blank",groups={"new"}) * @Assert\Choice(choices = {"male", "female"}, message = "Choose a valid gender.", groups={"new"}) */ private $gender; 和"male"进行硬编码。可以这样做吗？

  

choices = {self :: GENDER_MALE，self :: GENDER_FEMALE}

Answer 1

这是Doctrine2 Annotation Reader (Constants)的一项功能。

你解决方案：

class Student
{
    const GENDER_MALE = "male", GENDER_FEMALE = "female";

    /**
     * @var string $gender
     *
     * @ORM\Column(name="gender", type="string", length=50,nullable=false)
     * @Assert\NotBlank(message="Gender cannot be blank",groups={"new"})
     * @Assert\Choice(
     *      choices = {
     *          Student::GENDER_FEMALE: "Female",
     *          Student::GENDER_MALE: "Male"
     *      },
     *      message = "Choose a valid gender.", groups={"new"}
     * )
     */
    private $gender;
}
