Question

  if ($cart = $this->cart->contents())
  {
        foreach ($cart as $item){
            $order_detail = array(
                'res_id'        =>$this->session->userdata('menu_id[]'),
                'customer_id'   =>$coustomers,
                'payment_id'    =>$payment,
                'name'          => $item['name'],
                'productid'     => $item['id'],
                'quantity'      => $item['qty'],
                'price'         => $item['price'],
                'subtotal'      => $item['subtotal']
            );  
            }
            print_r($order_detail); exit;

当foreach循环结束时，只剩下最后一个迭代值。我需要将所有值都放在数组中。

Answer 1

更改此行

Route::get('contacts/new', 'ContactController@new_contact');
Route::get('contacts/{id}', 'ContactController@get_contact');

到

$order_detail = array(..);

Answer 2

因为order_detail每次都会覆盖。使用数组而不是简单变量。

$order_detail = array();
if ($cart = $this->cart->contents())
  {
    foreach ($cart as $item){
        $order_detail[] = array(
            'res_id'        =>$this->session->userdata('menu_id[]'),
            'customer_id'   =>$coustomers,
            'payment_id'    =>$payment,
            'name'          => $item['name'],
            'productid'     => $item['id'],
            'quantity'      => $item['qty'],
            'price'         => $item['price'],
            'subtotal'      => $item['subtotal']
        );  
      }
print_r($order_detail); exit;

Answer 3

试试这个首先定义数组

$order_detail=array();

array_push($order_detail, array(...));

数组声明必须在循环之外。

最后一次迭代值留在数组中
