'gambar' => $this->input->post('gambar'),
//'seller' => $this->input->post('seller'),
'qty' => $this->input->post('qty')
);
//die(print_r($data_produk));
$this->cart->insert($data_produk);
$cart = $this->cart->contents();
if(!empty($cart)){
// print_r($cart);
}
redirect('product');
}

In my last project I could use cart functionality with it, but in this project cart remains empty, can you point me where my code is wrong?

Answer 1

Codeigniter Cart Using English in it array keys, (unless you modified it somehow)
This should work - Notes: Add any extra data you may need to save under options, don't define your own array key. check here for more Codeingiter Cart
$data_produk = array(
'id' => 'sku_123ABC',
'qty' => 1,
'price' => 39.95,
'name' => 'T-Shirt',
'options' => array('Size' => 'L', 'Color' => 'Red')
);
instead of this
$data_produk= array('id' => $this->input->post('id'),
'nama_produk' => $this->input->post('nama_produk'),
'harga' => $this->input->post('harga'),
'gambar' => $this->input->post('gambar'),
//'seller' => $this->input->post('seller'),
'qty' => $this->input->post('qty')
);
Try to map that according to your language
