PHP Add array items from an inner array loop - php

Question

I am trying to build an array of cart items that has a mix of a la carte items and package deals. I want to pull the products from the packages and enter the products into my order table. Below is what I have. It pulls the data, but will only add the last record of the inner array (package products) to the outer array. The a la carte items are fine.
$sql = "SELECT id, item_id, package
FROM cart WHERE user_id = $userId";
$result = dbQuery($sql);
$arrCartContent = array();
while ($row = dbFetchAssoc($result)) {
if ($row['package'] == 1) {
// Add Product Credits to Company and Order
$arrProductData = fetchProductDataByPackage($row['item_id']);
$numItem = count($arrProductData);
if ($numItem > 0) {
for ($i = 0; $i < $numItem; $i++) {
extract($arrProductData[$i]);
$row['product_id'] = $product_id;
$row['description'] = $pack_product_name;
}
}
} else {
$itemDetails = fetchProductDetails($row['item_id']);
$row['product_id'] = $row['item_id'];
$row['description'] = $itemDetails['name'];
}
$arrCartContent[] = $row;
}
if(!empty($arrCartContent)) {
foreach ($arrCartContent as $cartData) {
$product_id = $cartData['product_id'];
$description = $cartData['description'];
$sqlInsert = "INSERT INTO shop_order_x_product
(order_id, product_id, description)
VALUES
($orderId, $product_id, '$description')";
$resultInsert = dbQuery($sqlInsert) or die('Cannot add order products: ' . mysql_error());
}
}

You mixed it up a bit, your general approach is fine, maybe streamlining it a bit will make this a breeze and prevent you from overwriting the $row variable inside the loop:
$arrCartContent = array();
while ($row = dbFetchAssoc($result))
{
if ($row['package'] == 1)
{
// Add Product Credits to Company and Order
$arrProductData = fetchProductDataByPackage($row['item_id']);
foreach($arrProductData as $productData)
{
$new = array();
$new['product_id'] = $productData['product_id'];
$new['description'] = $productData['description'];
$arrCartContent[] = $new;
}
}
else
{
$itemDetails = fetchProductDetails($row['item_id']);
$new = array();
$new['product_id'] = $row['item_id'];
$new['description'] = $itemDetails['name'];
$arrCartContent[] = $new;
}
}

You're overwriting the $row array elements with each iteration. Try...
if ($row['package'] == 1) {
// Add Product Credits to Company and Order
$arrProductData = fetchProductDataByPackage($row['item_id']);
$numItem = count($arrProductData);
if ($numItem > 0) {
for ($i = 0; $i < $numItem; $i++) {
extract($arrProductData[$i]);
$row['product_id'] = $product_id;
$row['description'] = $pack_product_name;
$arrCartContent[] = $row;
}
}
} else {
$itemDetails = fetchProductDetails($row['item_id']);
$row['product_id'] = $row['item_id'];
$row['description'] = $itemDetails['name'];
$arrCartContent[] = $row;
}
