私はオンラインストアで働いています。プロジェクトの目的は、製品をショッピング カートに追加することです。顧客は、製品の数量ごとにサイズと長さを変更できる必要があります。例 ：

  • Aという名前の商品を販売しています
  • 顧客注文 5 個の製品 A
  • したがって、商品 A の数量は 5 であるため、5 つのサイズと長さを設定できるはずです。

次に、作成された請求書を電子メールで送信するための TCPDF もあります。

数量ごとにサイズと長さを設定する方法を教えてください。助けてください..

また、可能であれば、これらの長さとサイズを関数 sendmail の下に作成された pdf に追加するのを手伝ってください

以下は、私が今まで書いたコードです...

別のセッションを作成して実行しようとしましたが、自分で実行できないようです。

数量を 5 に変更すると、サイズのドロップダウンが 5 つ、長さのドロップダウンが 5 つ表示されるはずです。ドロップダウンを作成できましたが、選択した値をセッションに保存できませんでした。

どんな助けでも大歓迎です。

これを説明するために、Shopping Cart という名前のセッションがあります。価格、サイズ、数量などの配列項目があります。関数があります:- 

else if (isset($_POST['update'])) {
//Updates Qty for all items
foreach ($_POST['items_qty'] as $itemID => $qty) {
//If the Qty is "0" remove it from the cart
if ($qty == 0) {
//Remove it from the cart
unset($_SESSION['SHOPPING_CART'][$itemID]);
}
else if($qty >= 1) {
//Update to the new Qty
$_SESSION['SHOPPING_CART'][$itemID]['qty'] = $qty;

}
foreach ($_POST['items_size'] as $itemID => $size) {
//If the Qty is "0" remove it from the cart
if($size >= 1) {
//Update to the new Qty
$_SESSION['SHOPPING_CART'][$itemID]['size'] = $size;

}
}
foreach ($_POST['items_length'] as $itemID => $length) {
//If the Qty is "0" remove it from the cart

//Update to the new Qty
$_SESSION['SHOPPING_CART'][$itemID]['length'] = $length;


}
}

ここでは、各製品のサイズと長さを更新しています。数量ごとに欲しいです。たとえば、5 個の数量を選択した場合、顧客は 5 つのサイズと 5 つの長さを選択できるはずですが、現在、数量がどれほど大きくても、それぞれ 1 つしか選択できません。

まず、名前や自動生成されたインデックスではなく、ID を使用してアイテムをセッションに保存する必要があります。名前が変わると、データベースでそれらを見つけることができなくなります。その ID を で直接使用する$_SESSION['SHOPPING_CART'][ 'item_id' ] = array()必要があります。これにより、アイテムをすばやく見つけて操作できるようになります。

同じアイテムの複数のエンティティがあるため、より複雑な配列を使用してそれらを格納する必要があります。簡単な解決策は次のとおりです。

$ITEM = array(
    'name' => $_GET['add'],
    'qty' => $_GET['qty'],
    'price' => $_GET['price'] * $_GET['qty'],
    'size' => array_fill(0, $_GET['qty'], $_GET['size']),
    'length' => array_fill(0, $_GET['qty'], $_GET['length']),
    'code' => $_GET['code']
);
$_SESSION['SHOPPING_CART'][ $_GET['item_id'] ] =  $ITEM;

ユーザーがデータを変更したい場合は、サイズと長さの配列のすべての行にドロップダウンを作成し、それに応じて保存します。

ただし、このデータをデータベースに保存することをお勧めしますuser_id。現在の設計では、ユーザーが誤ってブラウザを閉じたり、セッションの有効期限が切れたときに戻ってきたりすると、注文全体が失われます。

編集:サイズと長さの操作。

foreach ($_SESSION['SHOPPING_CART'] as $item_id => $item)
{
    echo '<p>Name: ' . $item['name'] . ' for ' . $item['price'] . '$</p>';
    foreach($item['size'] as $j => $size)
    {
        echo '<p>#' . $j . ': size ' . $size . ', length ' . $item['length'][$j] . '</p>';
    }
}

echo を編集用の入力に置き換えて、フォームに入れます。
