Di sql sudah bisa tapi di php tidak bisa

saya membuat alter table DI SQL Tidak ada masalah. tapi ketika saya membuat inputan pada program web masih terjadi Integrity constraint violation

pada table Siswa

CREATE TABLE `tb_siswa` (
  `programid` int(5) NOT NULL,
  `jobid` int(5) NOT NULL,
  `classid` int(5) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

ALTER TABLE `tb_siswa`
  ADD CONSTRAINT `class` FOREIGN KEY (`classid`) REFERENCES `class` (`idclass`),
  ADD CONSTRAINT `job` FOREIGN KEY (`jobid`) REFERENCES `job` (`idjob`),
  ADD CONSTRAINT `program` FOREIGN KEY (`programid`) REFERENCES `program` (`idprogram`);
COMMIT;

pada table Program

CREATE TABLE `program` (
  `idprogram` int(5) NOT NULL,
  `programname` varchar(60) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

pada Table Job

CREATE TABLE `job` (
  `idjob` int(5) NOT NULL,
  `jobname` varchar(60) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

Pada Table Class

CREATE TABLE `class` (
  `idclass` int(5) NOT NULL,
  `classname` varchar(60) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
