我创建了一个类似于购物车的项目。
但是，用户需要在子窗口（Bootstrap Modal）上添加项目，然后提交后会自动在父窗口上显示该项目，而无需刷新页面。
提交项目时遇到问题，这些项目将另存为会话，然后在“父”窗口中检索。
我试图var_dump会话，它可以显示数组，但是我不知道在父窗口中检索会话数据。
控制器：
public function index(){
$data['session'] = is_array($this->session->userdata('item'))?array_values(unserialize($this->session->userdata('item'))) : array();
$data['product'] = $this->test->GetProduct();
$data['category'] = $this->test->GetCategory();
$this->load->view('import/test',$data);
}
public function AddCart(){
$product = $this->input->post('product_type');
$category = $this->input->post('category_code');
$qty = $this->input->post('qty');
$quality = $this->input->post('quality');
$gold_rate = $this->input->post('gold_rate');
$weight = $this->input->post('weight');
$item_remarks = $this->input->post('item_remarks');
$assessed_value = $this->input->post('assessed_value');
$pledge_amt = $this->input->post('pledge_amt');
$Pledge_Item = array(
'Product' => $product,
'Category' => $category,
'Qty' => $qty,
'Quality' => $quality,
'Gold_Rate' => $gold_rate,
'Weight' => $weight,
'Item_Remarks' => $item_remarks,
'Assessed_Value' => $assessed_value,
'Pledge_Amt' => $pledge_amt
);
//$this->session->set_userdata('item',$Pledge_Item);
//$Session = $this->session->userdata('item');
//var_dump($Session);
if(!$this->session->has_userdata('item')) {
$item = array($Pledge_Item);
$this->session->set_userdata('item', serialize($item));
} else {
//$index = $this->exists($product);
$item = array_values(unserialize($this->session->userdata('item')));
array_push($item, $Pledge_Item);
$this->session->set_userdata('item', serialize($item));
}
//var_dump($item);
redirect('Test/index');
