Ambil data sesuai id-nya dan secara bersamaan ada form isian baru sesuai id tersebut

Selamat malam para senior, saya kebingungan bagaimana caranya Ambil data sesuai ID-nya dan secara bersamaan ada form isian baru sesuai ID tersebut. jadi saya ada data di tabel Nota Dinas dengan ID (id_notadinas) kemudian saya ingin ambil ID tersebut untuk input data ditabel Pelaksana yang memiliki isi ID yang sama. intinya saya ingin menggunakan ID di Tabel Nota Dinas untuk digunakan saat input Tabel Pelaksana (otomatis saat saya klik aksi read, tampil data nota dinas berdasarkan ini dan bersamaan ada form isian baru sesuai id yang tampil untuk input data pelaksana SPPD).

untuk codenya seperti ini :
