$ _session的購物車並發送產品名稱和數量我如何同時發送總成本

Question

下面是用於發送產品名稱和數量的代碼，這很完美，我想在發送名稱和數量的同時發送總成本，但是不確定如何進行此操作，因為這對php來說還很新提前致謝

<?php
  if (isset($_POST['form_products'])) {
    $quantity=$_POST['quantity'];
    $total = $the_price_is * $quantity; // want to be able to send $total at same time
    $order = array($_POST['dryer']=>$_POST['quantity']);
    if (!empty($_SESSION['products'])) {
      foreach($_SESSION['products'] as $name => $quantity_value){
        if (isset($order[$name])){
          print "<br>Your order as been added to your cart";
          $order[$name]+=$quantity_value;
        }
      }
      $order = array_unique(array_merge($_SESSION['products'], $order));
    }
    $_SESSION['products'] = $order; 
  }

我在這里采取了一個非常快速且有點混亂的方法。 從根本上來說，我不同意您的處事方式，您應該真正考慮使用一種面向對象的方法-但是為了使事情做好，這應該可以解決您的問題並在將來提供更多的靈活性。

哦，有機會請檢查一下： http : //php.net/manual/en/function.array-unique.php

您的array_unique（array_merge ...代碼將合並所有具有相同數量的產品，並且您將從陣列中丟失產品。:)

如有任何疑問，請將其解雇。

// im assuming you've called this somewhere already:
// session_start();

// store the initial details
$quantity = $_POST['quantity'];
$total = $the_price_is * $quantity; // want to be able to send $total at same time

// build multi-dimensional order array
$order = array(
    $_POST['dryer'] => array('quantity' => $_POST['quantity'], 'total' => $total)
);

// merge any session products into the order array if necessary
if (isset($_SESSION['products']) && is_array($_SESSION['products']) ) foreach ($_SESSION['products'] as $name => $details) {

    // add quantity and total if the 'product' is already in the session
    if (isset($order[$name])) {
        $order[$name]['quantity'] += $details['quantity'];
        $order[$name]['total'] += $details['total'];
    } else $order[$name] = $details;

}


// replace session products with newly built order array
$_SESSION['products'] = $order;
