Codeigniter购物车无法添加项目 [英] Codeigniter Cart cannot add items
问题描述
所以我试图用购物车创建一个应用程序,当我尝试添加商品时,它无法正常工作。顺便说一句,我已经有一个有效的购物车应用程序,这就是为什么我想知道为什么它无法正常工作的原因。我几乎复制了工作中的所有内容。这是代码
So i'm trying to create an application with cart and when i tried adding the item, it's not working. By the way i already have a working cart application that's why i'm wondering why it's not working. I almost copied everything from the working one. here's the code
购物车控制器
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Cart extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->library('cart');
}
public function add_to_cart(){
$id = $this->uri->segment(3);
if($this->cart->contents()){
foreach ($this->cart->contents() as $item){
if ($item['id']==$id){
$data = array('rowid'=>$item['rowid'],
'qty'=>++$item['qty']);
$process = $this->cart->update($data);
}
else{
$data = array(
'id'=>$id,
'qty'=>1,
'name' => $this->get_data->get_value('product_name','products','product_id', $id),
'price' => $this->get_data->get_value('product_price','products','product_id', $id)
);
$process = $this->cart->insert($data);
}
}
}
else{
$data = array('id'=>$id,
'qty' =>1,
'name' => $this->get_data->get_value('product_name','products','product_id', $id),
'price' => $this->get_data->get_value('product_price','products','product_id', $id),
);
$process = $this->cart->insert($data);
}
if($process){
$this->session->set_flashdata('success', 'Successful');
redirect('products');
}
else{
$this->session->set_flashdata('failed', 'Failed');
redirect('products');
//var_dump($process);
}
}
这里是按钮
<div class="button pull-right" style="margin-top: 10px;"><a href="<?php echo base_url().'cart/add_to_cart/'.$row->product_id;?>"><span class="glyphicon glyphicon-shopping-cart"></span>Add to Cart</a></div>
我真的看不到问题,我正在使用会话数据库,sess_us_database已经为TRUE 。我尝试使用 var_dump($ process)
,这是错误的,我尝试了 var_dump($ data)
并且数据似乎很好,但是插入部分无法正常工作。有想法吗?
I really can't see the problem, i'm using session database, the sess_us_database is already TRUE. I tried using var_dump($process)
and it's false, i tried var_dump($data)
and the data seems to be fine but the insert part isn't working. Any idea guys? it would be a big help for me, thank you.
推荐答案
CI默认默认购物车仅允许 alpha-产品名称中的数字,破折号,下划线,冒号或点号
,并且如果产品价格为 0
,那么该产品也不会添加到购物车中。
CI Default cart allows only alpha-numeric, dashes, underscores, colons or periods
in Product Name and If Price of product is 0
then also it will not add the product to cart.
请先检查一下。
