Mutiple input array dengan value berbeda tiap row nya

saya ingin membuat multi insert. saat melooping modality(dengan metode SELECT dari table berbeda dengan variable "pk_mod") berhasil masuk ke database. namun ketika ingin input harga & qty. harga & qty nya tidak ikut ter looping(terforeach) meskipun coding nya suda saya letakan didalam foreach dan didalam database nya terinput "array" tidak sesuai dengan value yg saya input
