As per title, I have a problem when adding products to the cart: it would show a window message that says that the product has been added, but in truth it is not there. It gives the following error:
Fatal error: Cannot use object of type stdClass as array
the line is: <td><?php echo $value['item_name']; ?></td>
Here is the code file reserve.php :
<?php
session_start();
ini_set('display_errors', 1);
$connect = mysqli_connect('127.0.0.1', 'root', '***********', 'Community Garden List');
if (isset($_POST['add'])) {
if (isset($_SESSION['cart'])) {
$item_array_id = array_column($_SESSION['cart'], 'product_id');
if (!in_array($_GET['id'], $item_array_id)) {
$count = count($_SESSION['cart']);
$item_array = array(
'product_id' => $_GET['id'],
'item_name' => $_POST['hidden_name'],
'product_price' => $_POST['hidden_price'],
'item_quantity' => $_POST['quantity'],
);
$_SESSION['cart'][$count] = $item_array;
echo '<script>window.location="reserve.php"</script>';
} else {
echo '<script>alert("Product is already Added to Cart")</script>';
echo '<script>window.location="reserve.php"</script>';
}
} else {
$item_array = array(
'product_id' => $_GET['id'],
'item_name' => $_POST['hidden_name'],
'product_price' => $_POST['hidden_price'],
'item_quantity' => $_POST['quantity'],
);
$_SESSION['cart'][0] = $item_array;
}
}
if (isset($_GET['action'])) {
if ($_GET['action'] == 'delete') {
foreach ($_SESSION['cart'] as $keys => $value) {
if ($value['product_id'] == $_GET['id']) {
unset($_SESSION['cart'][$keys]);
echo '<script>alert("Product has been Removed...!")</script>';
echo '<script>window.location="reserve.php"</script>';
}
}
}
}
?>
?>
html code
<?php
$query = 'SELECT * FROM product ORDER BY serial ASC';
$result = mysqli_query($connect, $query);
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_array($result)) {
?>
<div class="col-md-4">

<?php
if(!empty($_SESSION["cart"])){
$total = 0;

?>

</div>
</div>
I've tried print "<pre>"; var_dump($row); exit; after this line: foreach e($_SESSION['cart'] as $key => $value) { and it comes a table with NULL inside. What does that mean?
Before that, i tried to change $value['item_name'] with $value->item_name , and i got the following error:
Notice: Undefined property: stdClass::$item_name in
Will you please help me to understand what's wrong? thank you.
