In normal use of the module: When x product is added to my cart, it applies a% discount to product y. I want to add x product to my cart. And if the second x item is added to the cart, only the second item should receive up to a% discount. The third product should not be discounted, but the fourth product.
In the module, when I apply a discount for multiple items, it does not check whether the product is the same product. It is sufficient to have any two of the discounted products in the cart.
For example; The products I discount are x, y, z. I require a 50% discount when there are at least 2 items in the cart.
Module: There is x, y in the cart. It applies 50%.
I want: There is x, y in the cart. There will be no discount. The cart has 2x, 1y. Discounts will only be applied to x. There are 2x and 2y. It will apply a discount to the second x and the second y.
I hope I could explain. Below is the required code block in the module.
My Opencart Version: 3.0.3.2
Code: Select all
$promo1 = $promo['condition_min_quantity'];
$promo2 = $promo['condition_product_ids'];
$promo3 = $promo['discount_quantity'];
$promo4 = array_intersect_assoc($promo['condition_product_ids'], $promo['discount_product_ids']);
$promo5 = $promo['discount_value'];
// Block early
if (!$promo1 || !$promo2 || !$promo3 || !$promo4 || !$promo5) {
return $promo;
}
$products = $this->_cart['products'];
$p_conditions = array( // Product conditions in cart
'products' => array(),
'total_quantity' => 0,
'condition_qty' => '2',
'base_multiply' => 0,
'qty_off' => 0,
);
$p_discounts = array(); // Product discounts in cart
$p_discounts_total = 0; // total quantity of free product in cart
foreach ($products as $product) {
if (in_array($product['product_id'], $promo['condition_product_ids'])) {
$p_conditions['products'][] = '<a href="' . $this->url->link('product/product', 'product_id=' . (int)$product['product_id'], true) . '">' . $product['name'] . '</a>';
$p_conditions['total_quantity'] += $product['quantity'];
$p_conditions['base_multiply'] = floor($p_conditions['total_quantity'] / $p_conditions['condition_qty']);
if ($p_conditions['base_multiply']) {
// Note: qty_off indicate the quantity of products that get discounts off
$p_conditions['qty_off'] = ($promo['apply_once'] ? 1 : $p_conditions['base_multiply']) * 1;
}
}
if (in_array($product['product_id'], $promo['discount_product_ids'])) {
$p_discounts[$product['product_id']] = array(
'product_id' => $product['product_id'],
'name' => $product['name'],
'quantity' => isset($p_discounts[$product['product_id']]['quantity']) ? $p_discounts[$product['product_id']]['quantity'] + $product['quantity'] : $product['quantity'],
'prices' => isset($p_discounts[$product['product_id']]['prices']) ? $p_discounts[$product['product_id']]['prices'] + array($product['islpr_cart_id'] => $product['price']) : array($product['islpr_cart_id'] => $product['price']),
'tax_class_id' => $product['tax_class_id'],
);
$p_discounts[$product['product_id']]['least_price'] = min($p_discounts[$product['product_id']]['prices']);
$p_discounts[$product['product_id']]['most_price'] = max($p_discounts[$product['product_id']]['prices']);
$p_discounts_total = $p_discounts_total + $product['quantity'];
}
}
