Codeigniter foreach Undefined variable - php

Question

I want to calculate hargaLama and hargaBaru, then insert it into database. To do so, I retrieve hargaLama from a view in mysql to my controller while hargaBaru is a user input. Even though I'm using foreach I got Undefined variable hargaLama and I also got error
Unknown column 'kodeProduksi' in 'field list'.
Here's my controller:
public function proses_tambahBarang(){
$kode = $_POST['kode'];
$kodeProduksi = $_POST['kodeProduksi'];
$nama = $_POST['nama'];
$tipe = $_POST['tipe'];
$ukuran = $_POST['ukuran'];
$merk = $_POST['merk'];
$satuan = $_POST['satuan'];
$jumlah = $_POST['jumlah'];
$harga = $_POST['hargaSatuan'];
// echo "proses_tambahBarang";
$data_insert = array(
'kodeBarang' => $kode,
'kodeProduksi' => $kodeProduksi,
'namaBarang' => $nama,
'tipeBarang' => $tipe,
'ukuran' => $ukuran,
'merk' => $merk,
'satuan' => $satuan,
'jumlah' => $jumlah,
'hargaSatuan' => $harga,
'keterangan' => 'n/a',
'idUser' => $this->session->userdata('username'),
'waktuMasuk' => 'n/a',
'waktuEdit' => 'n/a'
);
//$cek = $this->mhome->Barang("where kodeBarang = $data_insert[kodeBarang]");
// if($cek >= 1)
// {
$cek = $this->mhome->BarangHistory("where kodeProduksi = '$data_insert[kodeProduksi]'");
// $cek = $this->db->get_where('baranghistory',array('kodeProduksi' =>$data_insert['kodeProduksi']));
if($cek >= 1);
{
$query = $this->mhome->TableSelect('listBarang',"where kodeProduksi = '$data_insert[kodeProduksi]'");
foreach ($query as $row) {
$hargaLama = $row[0]['hargaSatuan'];
$jumlahLama = $row[0]['jumlah'];
}
$hargaBaru = $data_insert['hargaSatuan'];
$jumlahBaru = $data_insert['jumlah'];
$jumlahBaru = $jumlahBaru + $jumlahLama;
$data_insert['jumlah'] = $jumlahBaru;
$data_insert['waktuEdit'] = date("Y-m-d h:i:sa");
$data_insert['keterangan'] = "Updated";
$this->mhome->UpdateData('baranghistory',$data_insert,array("kodeProduksi" => $data_insert['kodeProduksi']));
$this->mhome->UpdateData('barang',$data_insert,array("kodeBarang" => $data_insert['kodeBarang']));
}
// $this->mhome->hitungHargaSatuan("where kodeBarang = '$data_insert[kodeBarang]'");
$hitung = $this->mhome->hitungHargaSatuan($data_insert['kodeBarang']);
if($hitung){
$this->session->set_flashdata('pesan','Tambah Barang Sukses');
redirect('userhome/index');
}
if($cek == 0) {
$data_insert['waktuMasuk'] = date("Y-m-d h:i:sa");
$data_insert['keterangan'] = "Baru";
$res = $this->mhome->InsertData('barang',$data_insert);
$res2 = $this->mhome->InsertData('baranghistory',$data_insert);
}
if($res >= 1 && $res2 >=1)
{
$this->session->set_flashdata('pesan','Tambah Barang Sukses');
redirect('userhome/index');
}
else {
echo "Tambah barang gagal";
}
}
And here's my model:
public function TableSelect($table,$where="")
{
$stmt = $this->db->query('select * from '.$table.' '.$where);
return $stmt->result_array();
}

Answer 1

I am sure you need not to put 0 here
foreach ($query as $row) {
$hargaLama = $row['hargaSatuan'];//remove [0] from here
$jumlahLama = $row['jumlah'];//remove [0] from here
}

Answer 2

like this.you need to use count on codition because this is returned array.and use result_array() for getting result in array format.
$cek = $this->mhome->BarangHistory("where kodeProduksi = $data_insert['kodeProduksi']")->result_array();
// $cek = $this->db->get_where('baranghistory',array('kodeProduksi' =>$data_insert['kodeProduksi']))->result_array();
if(count($cek) >= 1);
{
$query = $this->mhome->TableSelect('listBarang',"where kodeProduksi = $data_insert['kodeProduksi']");
foreach ($query as $row) {
$hargaLama = $row['hargaSatuan'];
$jumlahLama = $row['jumlah'];
}
