gan ane kan bikin pemesanan barang gitu,nah kondisi pemesanannya barang nya itu ada 2 kondisi,yang stok nya kosong dan yang ada stok...kalo stok nya ada,pada saat membeli barang akan di masukkan ke keranjang belanja biasa,tpi disaat stok kosong akan dimasukkan ke keranjang indent....jadi disini ada 2 keranjang belanja gan,yg pertama keranjang biasa,yang kedua keranjang buat indent,dan keduanya berada pada file php yg berbeda
Nah yg jadi permasalahannya,di saat ane ngeklik tombol indent dari barang yg stok nya 0(kosong) barang tersebut berhasil nongol di keranjang indent gan,tpi pas ane coba cek keranjang yg biasa,barang nya juga nongol gan,seharusnya yg bisa nongol di keranjang biasakan yg bukan pemesanan indent gan...begitu pun sebaliknya...ane udah coba ngebedain variable get nya tetap ga bisa gan.... gini kodingannya gan...
