Count the items in mini cart

-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.5.1

hi,
i'm using this code to return the number of items in my mini cart,

if(!defined('DS'))
	define('DS', DIRECTORY_SEPARATOR);
if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php'))
	return true;

$cartClass = hikashop_get('class.cart');
$fullCart = $cartClass->loadFullCart();
$nbProducts = 0;
foreach($fullCart->products as $product){
    $nbProducts += $product->cart_product_quantity;
}
	echo $nbProducts;

also i want an if condition like this:

if user has an item in cart {do this }
else { do that }

okay then
so i should use this code:

<?php
if(!defined('DS'))
	define('DS', DIRECTORY_SEPARATOR);
if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php'))
	return true;

$cartClass = hikashop_get('class.cart');
$fullCart = $cartClass->loadFullCart();
$nbProducts = 0;
foreach($fullCart->products as $product){
    if($group && $row->cart_product_option_parent_id) continue;
    $nbProducts += $product->cart_product_quantity;
}
	echo $nbProducts;

?>

if($group && $row->cart_product_option_parent_id) continue;

i also want the mini cart to show up the shop-card ul list with a message of "nothing in cart" inside it.
but when shopping cart is empty nothing happens when i click on mini card icon.

can you give me a help on this too ?

thanks

how can i make hikashoping cart module to show up when its empty and show me a message like "cart is empty" instead of not doing anything at all when it's empty !
it's like a corrupted cart when nothing is in cart nothing will happen when user clicks on the logo !

my hikashop version is 2.6.3
in this version hikashop cart is not loading anything when cart is empty !
i think this ability that u are saying is on 2.6.4 right ?

if so can you please tell me how to only update the hika cart module ?

thanks

Hello Nicolas,
on a new project, i'm trying to show the numbers of Main Product inside the cart at bottom of cart drop down.
i'm using this line of codes but it counts the product Options too.
for example with i have two product with Option and Characteristic it count it as 3 instead of 1 !
how can i remove Characteristic and Options from Product count in this code?

<?php 	
	$config = hikashop_config();
	$group = $config->get('group_options');
	if(!defined('DS'))
	define('DS', DIRECTORY_SEPARATOR);
	if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php'))
		return true;

	$cartClass = hikashop_get('class.cart');
	$fullCart = $cartClass->loadFullCart();
	$nbProducts = 0;
	foreach($fullCart->products as $product){
	    if($group && $row->cart_product_option_parent_id) continue;
	    $nbProducts += $product->cart_product_quantity;
	}
		echo $nbProducts;
?>

Hello Jerome,
thanks for your explanation you are right cause I have variants (Product Type) assigned to the main product,
with this explanations.
is there any way to count only the main products?
i don't want the variants (Type Product or not) to be counted as a product (Main) in the cart !
is there any trick or hint you can tell me?

Hello Nicolas,
Thank you for your answer,
i've tried to skip the variants from counting as you said but i think there is something wrong or something i'm mistaking about.

i tried this line of codes and it's still counting the variant with the main product.



<?php
$cartClass = hikashop_get('class.cart');
$fullCart = $cartClass->loadFullCart();
$nbProducts = 0;
foreach($fullCart->products as $product){
if(!$product->product_parent_id) continue;
$nbProducts += $product->cart_product_quantity;

}
echo $nbProducts;

?>

i'm sorry if i'm asking to much but i rally appreciate it if you can tell me what i'm doing wrong with these line of codes ?



Thanks

Hello Jerome,
I tried that but it's not giving me the count of ONLY main products yet!

can you please do me a favor at giving me the exact line of codes that can echo the count of the main product inside cart?
or tell me how to use $cart->quantity->total and $cart->quantity->items and filter the variants and options from count ?

P.S: i'm using the latest version of Hikashop.

Hi,
I have HikaShop 3.1.1 installed.
I want to add a code to show the number of main products inside the cart!
My problem is that the line of codes I'm using and you are saying are counting the product variant and options too.
For example, when I add a product to cart with 12-month warranty (Options) and software package (Variants) the counter shows 3 instead of one!
I want the counter to only count the main product.
You have done me a favor and told me to use this code $cart->quantity->total or $cart->quantity->items but these codes are also counting the variants and options too.

this is my final code and it returens 3 instead of 1 :

		<?php 	
			$config = hikashop_config();
			$group = $config->get('group_options');
			if(!defined('DS'))
			define('DS', DIRECTORY_SEPARATOR);
			if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php'))
				return true;
		
			$cartClass = hikashop_get('class.cart');
			$fullCart = $cartClass->loadFullCart();
			$nbProducts = 0;
			foreach($fullCart->products as $product){
			    if($group && $row->cart_product_option_parent_id) continue;
			    $nbProducts += $product->cart_product_quantity;
			}
				echo $nbProducts;
				echo $cart->quantity->total;
				echo $cart->quantity->items;
		
		?>
		
		<?php $cart->quantity->items ?>
