How to get cart data inside array in codeigniter - php

Question

i have 2 products in my cart session. and want me to combine in array data_order. but read only 1 product. actually this data I will send in an email so from that I make the format of the data like this.
my controller :
foreach ($this->cart->contents() as $item){
if($item['diskon'] == "0"){
$harga_before = $item['before'];
$harga_after = $item['price'];
}else{
$harga_before = $item['before'];
$harga_after = $item['price'];
}
foreach ($this->cart->product_options($item['rowid']) as $option_name => $option_value){
if(empty($option_value)){
$option_size = "";
$option_color = "";
}else{
$option = $item['options'];
$option_size = $option['Size'];
$option_color = $option['Warna'];
}
}
$data = array(
'inv' => $invoice,
'tglOrdercs' => date('d F Y H:i:s'),
'tglExp' => $date_maju,
'nmlkp' => $nmlkpi,
'almtkp' => $address,
'noTelp' => $notelp271,
'methode' => $method,
'bnk_option' => $banking_select,
'data_order' => array(
'nama_produk' => $item['name'],
'artikel' => $item['artikel'],
'diskon' => $item['diskon'],
'ukuran' => $option_size,
'warna' => $option_color,
'qty' => $item['qty'],
'harga_fix' => $harga_after,
'harga_before' => $harga_before,
),
);
}
my result :
