Я очень новичок в php и пытаюсь создать страницу корзины.
Iv получил идентификатор продукта, опцию и цену, отправленные с использованием массива $ _POST.
Я хочу, чтобы $ino содержал значение Id, что я и делаю.
Я получаю одну повторяющуюся ошибку.
Примечание: неопределенный индекс: 3 в /home/sl0/s3196040/public_html/wp/a3/cart.php в строке 84 Имя: Примечание: неопределенный индекс: 3 в / home / sl0 / s3196040/public_html/wp/a3/cart.php в строке 71 Цена: Примечание: неопределенный индекс: 3 в /home/sl0/s3196040/public_html/wp/a3/cart.php в строке 74 **
Я знаю, что я должен "isset" $ ino, чтобы проверить, установлен он или нет, но я думал, что у меня есть?
Если я набираю значение вручную, например $pumps[3]['Title'], оно работает, но не работает, если я использую переменную $ ino, как это $pumps[$ino]['Title'].
Это в массиве $ _POST ([Id] => 3 [option] => english [qty] => 3
define("TITLE", "Product Page");
include_once('tools.php');
topModule('Business Name - Home', 'showSpecials()');
print_r($pumps[3]['Price']);
print_r($_POST);
// if i have the ID of the product, i need to turn it into a variables that the cart can display
if (isset ( $_POST ['Id'] )) {
// Check the item is not already in the cart
if (!in_array($_POST ["Id"], $_SESSION['cart'])) {
// Add new item to cart
$_SESSION ['cart'][] = $_POST["Id"];
}
}
else if (isset ( $_POST ['delete'] )) { // a remove button has been clicked
// Remove the item from the cart
if (false !== $key = array_search($_POST['delete'], $_SESSION['cart'])) {
unset($_SESSION['cart'][$key]);
}
// Empty Cart
else if (isset ( $_POST ["delete"] )) { // remove item from cart
unset ( $_SESSION ['cart'] );
}
}
if (isset ( $_SESSION ["cart"] )) {
if (isset($_POST['submit'])) {
$ino = $_POST['submit'];
}
