MySQLi et PHP envoie uniquement des produits uniques sur la base de données

Question

Je ne peux pas trouver où est le problème à mon code. Il n'envoie que des commandes uniques à la base de données. Quand je commande dans mon panier 2 ou plus que des articles, il envoie seulement la dernière commande. Je n'ai aucune idée de comment je peux changer ou ajouter de la syntaxe dans mon code.

Voici mon code dans checkout.php

<?php 
session_start(); 
echo '<h3>Your Order</h3>'; 
$current_url = base64_encode($url='http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); 
    if(isset($_SESSION['products'])){ 
    echo '<ol>'; 
    echo '<form action="checkout_with_us.php" method="POST">'; 
    $total = 0; 
    $cart_items = 0; 

     foreach($_SESSION['products'] as $cart_itm){ 
      $product_code = $cart_itm['code']; 
      $results = $mysqli->query("SELECT product_name,product_desc,price FROM products WHERE product_code='$product_code' LIMIT 1"); 
      $obj = $results->fetch_object(); 
       echo '<li>'; 
       echo 'Price: '.$currency.$obj->price; 
       echo '<h4>'.$obj->product_name.'(Code: '.$product_code.')</h4>'; 
       echo 'Qty: '.$cart_itm['qty']; 
       echo '</li>'; 

        $subtotal = ($cart_itm['price'] * $cart_itm['qty']); 
        $total = ($total + $subtotal); 
        $cart_items++; 
         echo '<input type="hidden" name="item_name" value="'.$obj->product_name.'">'; 
         echo '<input type="hidden" name="item_desc" value="'.$obj->product_desc.'">'; 
         echo '<input type="hidden" name="item_qty" value="'.$cart_itm["qty"].'">'; 
         echo '<input type="hidden" name="item_code" value="'.$product_code.'">';  
       } 
        echo '<strong>Sub Total: '.$currency.$total.'</strong>'; 
        echo '<input type="hidden" name="price" value="'.$total.'">'; 
        echo '</ol>'; 
        } 

//Here is the information of the customer 
echo 'Firstname: <input type="text" name="firstname"><br />'; 
echo 'Lastname: <input type="text" name="lastname"><br />'; 
echo 'Email: <input type="text" name="email"><br />'; 
echo '<input type="submit" value="Send Step">'; 

echo '</form>'; 
?> 

Et voici mes codes checkout.with_us.php. Ce code est le pont pour envoyer les informations à la base de données.

<?php 
session_start(); 
$firstname = $_POST['firstname']; 
$lastname = $_POST['lastname']; 
$email = $_POST['email']; 
$order_name = $_POST['item_name']; 
$order_code = $_POST['item_code']; 
$order_qty = $_POST['item_qty']; 
$sub_total = $_POST['price']; 

$conn = mysqli_connect('localhost','root','','sampsix')or die('Could not connect'); 

$query = "INSERT INTO `sampsix`.`orders`(`firstname`,`lastname`,`email`,`OrderName`,`OrderCode`,`OrderQty`,`SubTotal`) VALUES('$firstname','$lastname','$email','$order_name','$order_code','$order_qty','$sub_total')"; 

mysqli_query($conn,$query); 

mysqli_close($conn); 

header('Location: checkout.php'); 
?>

Supprimer votre autre question, d'accord?

Le problème est que vous bouclez $_SESSION et utilisez la même valeur name chaque fois. Vous devez créer un tableau de vos entrées. Voici un exemple:

<?php 
echo '<h3>Your Order</h3>'; 
$current_url = base64_encode($url='http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); 
    if(isset($_SESSION['products'])){ 
    echo '<ol>'; 
    echo '<form action="checkout_with_us.php" method="POST">'; 
    $total = 0; 
    $cart_items = 0; 

     foreach($_SESSION['products'] as $cart_itm){ 
      $product_code = $cart_itm['code']; 
      $results = $mysqli->query("SELECT product_name,product_desc,price FROM products WHERE product_code='$product_code' LIMIT 1"); 
      $obj = $results->fetch_object(); 
       echo '<li>'; 
       echo 'Price: '.$currency.$obj->price; 
       echo '<h4>'.$obj->product_name.'(Code: '.$product_code.')</h4>'; 
       echo 'Qty: '.$cart_itm['qty']; 
       echo '</li>'; 

        $subtotal = ($cart_itm['price'] * $cart_itm['qty']); 
        $total = ($total + $subtotal); 
        $cart_items++; 
         echo '<input type="hidden" name="product['.$product_code.'][item_name]" value="'.$obj->product_name.'">'; 
         echo '<input type="hidden" name="product['.$product_code.'][item_desc]" value="'.$obj->product_desc.'">'; 
         echo '<input type="hidden" name="product['.$product_code.'][item_qty]" value="'.$cart_itm["qty"].'">'; 
         echo '<input type="hidden" name="product['.$product_code.'][item_code]" value="'.$product_code.'">';  
       } 
        echo '<strong>Sub Total: '.$currency.$total.'</strong>'; 
        echo '<input type="hidden" name="product['.$product_code.'][price]" value="'.$total.'">'; 
        echo '</ol>'; 
        } 

//Here is the information of the customer 
echo 'Firstname: <input type="text" name="firstname"><br />'; 
echo 'Lastname: <input type="text" name="lastname"><br />'; 
echo 'Email: <input type="text" name="email"><br />'; 
echo '<input type="submit" value="Send Step">'; 

echo '</form>'; 
?> 

Vous pouvez prendre cela en boucle dans votre tableau product:

<?php 
$firstname = $_POST['firstname']; 
$lastname = $_POST['lastname']; 
$email = $_POST['email']; 

$conn = mysqli_connect('localhost','root','','sampsix')or die('Could not connect'); 

foreach($_POST['product'] as $product) 
{ 
    $order_name = $product['item_name']; 
    $order_code = $product['item_code']; 
    $order_qty = $product['item_qty']; 
    $sub_total = $product['price']; 

    $query = "INSERT INTO `sampsix`.`orders`(`firstname`,`lastname`,`email`,`OrderName`,`OrderCode`,`OrderQty`,`SubTotal`) VALUES('$firstname','$lastname','$email','$order_name','$order_code','$order_qty','$sub_total')"; 
    mysqli_query($conn,$query); 
} 



mysqli_close($conn); 

header('Location: checkout.php'); 
?> 

Je ne sais pas quel est le but de la table orders mais avec mon exemple, les produits seront être ajouté à ce tableau avec le même firstname, lastname, etc.
