购物车在codeigniter中无法正常工作

Question

我正在尝试将商品添加到购物车，但它只会将前6个商品添加到购物车。其余的似乎没有被添加。

我检查了数组，他们有所需的ID，数量，价格和名称。我做错了什么？

以下是代码：

function add_cart_item() {

    $id = $this->input->post('product_id'); // Assign posted product_id to $id
    $cty = $this->input->post('quantity'); // Assign posted quantity to $cty
    $colors = $this->input->post('color_id'); // Assign posted color to $colors
    $sizes = $this->input->post('size_id'); // Assign posted size to $sizes

    $warna = "warna";
    $ukuran = "ukuran";

    //Ini untuk warna
    $sqlNameColor = 'SELECT NAME FROM ref_colors WHERE ID = "'.$colors.'"';
    $queryNameColor = $this->db->query($sqlNameColor);
    $color_id = $queryNameColor->row()->NAME;

    //Ini untuk ukuran
    $sqlNameSize = 'SELECT NAME FROM ref_sizes WHERE ID = "'.$sizes.'"';
    $queryNameSize = $this->db->query($sqlNameSize);
    $size_id = $queryNameSize->row()->NAME;

    //Ini untuk weight
    $sqlWeight = 'SELECT WEIGHT FROM v_weight WHERE PRODUCT_ID = "'.$id.'"';
    $queryWeight = $this->db->query($sqlWeight);
    $weight = $queryWeight->row()->WEIGHT;

    $product = $this->model_product->get($id);


    $data = array(
                'id'      => $id,
                'qty'     => $cty,
                'price'   => $product->PRICE,
                'name'    => $product->NAME,
        'colors'  => $color_id, 
        'sizes'   => $size_id,
        'colors_id' => $colors,
        'weight' => $weight,
        'size_id' => $this->input->post('size_id'),
        'image'   => $product->IMAGE,
        'options'=>array('Size' => $this->input->post('size_id'), 'Color' => $this->input->post('color_id'))


            );

            $this->cart->insert($data);
    $data['cart_list'] = $this->cart->contents(); 
    show_shoppingcart('shoppingcart_view', $data);

}

问题是当我在购物车中添加选项值时。

这是数组结果：

Answer 1

瑞安是对的。 这是适用于我的SQL。

CREATE TABLE `ci_sessions` (
  `session_id` varchar(40) NOT NULL DEFAULT '0',
  `ip_address` varchar(16) NOT NULL DEFAULT '0',
  `user_agent` varchar(50) NOT NULL,
  `last_activity` int(10) unsigned NOT NULL DEFAULT '0',
  `user_data` text NOT NULL,
  PRIMARY KEY (`session_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

启用会话数据库可以解决问题，您的会话无法保存您的购物车数据，这就是您只能添加6个项目的原因。
