Php Shopping cart – Размер и длина для каждого количества продукта

Я работаю в интернет-магазине. Цель проекта – добавить продукты в корзину покупок. Клиент должен иметь возможность изменять размер и длину для каждого количества продукта. Пример :

• Я продаю продукт под названием A
• заказ клиента 5 штук продукта A
• Поэтому он должен иметь возможность устанавливать 5 размеров и длины для продукта А в количестве 5.

Затем TCPDF также отправляет по электронной почте созданный счет-фактуру.

• TCPDF не отображает изображение с помощью writeHTML
• TCPDF добавляет цифровую подпись к созданному pdf
• правый логотип выравнивания в заголовке tcpdf
• TCPDF устанавливает нижнее поле нуля
• отправка вложения электронной почты с помощью TCPDF

Я просто хочу помочь с настройкой размеров и длины для каждого количества. Пожалуйста, помогите ..

Также, если это возможно, пожалуйста, помогите мне добавить эти длины и размеры в созданный pdf, который находится под функцией sendmail

Ниже приведен код, который я написал до сих пор …

Я попытался сделать это, создав еще одну сессию, но, похоже, не смог сделать это сам.

Я хотел сделать это как … когда вы измените количество до 5 … так что должно появиться 5 выпадающих меню для размера и 5 для длины. Я мог бы создавать выпадающие списки, но не смог сохранить выбранное значение в сеансе.

Любая помощь приветствуется.

Чтобы помочь это объяснить, Theres сеанс называется Корзина. Теперь, когда есть элементы массива, такие как величина размера цены и т. Д. Теперь есть функция: –

 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'] = $length; } } с else if (isset($_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; } } 

Здесь он обновляет размер и длину для каждого продукта. Я хочу это для каждого количества. Например, если вы выберете 5 штук, заказчик должен выбрать 5 размеров и 5 длин, текущий может выбрать только 1 каждый независимо от того, насколько велика величина. Возможно, это поможет вам понять

 $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;
