Bagaimaa Caranya Mengisi Beberapa Textbox saat pilih Dropdown

[i_kurnia]

Halo agan2 semua,

Saya Newbie di php Yii2, Sekarang saya lagi buat aplikasi Inventory menggunakan Yii2framworks,

cuma saat ini saya stack ada kendala. Yang saya maksud seperti berikut.

1. Saya buat sebuah Dropdown dari data tabel A (kode barang, nama barang) misalkan ditampilkan nama Barang.

2. Saat Dropdown itu dipilih datanya akan mengambil data di tabel B (isinya kode barang, lokasi dan jumlah) berdasarkan kode barang yang dipilih di Dropdown tsb,

3. Data yang diambil akan disimpan di 2 textbox, txtLokasi dan txtQuantity,

Pertanyaannya, bagaimana cara untuk membuat script langkah 2 dan 3.

Saya harap bantuan agan2 semua, Urgent pls.

Terima Kasih,

Iwan K
