Magento - Get products price with tax and discounts in cart/order (Criteo tags)

Question

For the implementation of Criteo tags, I'm trying to get the price (among other things) of all products in the cart (and success page) with tax and discounts. I'm currently doing something like this, but it only displays price with discount and without tax :

$cartAllItems = Mage::getModel('checkout/cart')->getItems();
foreach ($cartAllItems as $item){
    $price = Mage::helper('tax')->getPrice($item->getProduct(), $item->getProduct()->getFinalPrice());
    // other things
}

I've been testing around a lot of things and can't make it work. Thx for the help

Answer 1

You can get the discount and tax value per item and make the calculation.

$_item->getDiscountAmount
$_item->getTaxAmount

$totalItemPrice = $_item->getPrice - $_item->getDiscountAmount + $_item->getTaxAmount

Answer 2

I think you can use,

Mage::helper('checkout')->getQuote()->getShippingAddress()->getData('tax_amount')

This will return you total tax amount. or you can use

$totalItemsInCart = Mage::helper('checkout/cart')->getItemsCount();
$totals = Mage::getSingleton('checkout/session')->getQuote()->getTotals(); 
$subtotal = round($totals["subtotal"]->getValue()); 
$grandtotal = round($totals["grand_total"]->getValue()); 
if(isset($totals['discount']) && $totals['discount']->getValue()) {
   $discount = round($totals['discount']->getValue()); 
} else {
   $discount = '';
}
if(isset($totals['tax']) && $totals['tax']->getValue()) {
  $tax = round($totals['tax']->getValue()); 
} else {
  $tax = '';
}

Modified I guess for your requirement

foreach ($productIds as $productId) {
  $_product  = Mage::getModel('catalog/product')->load($productId);   
  $productsPrice = floatval($_product->getData("price")); 

  // Get the product's tax class' ID
  $taxClassId = $_product->getData("tax_class_id");
  echo 'Tax Class ID '.$taxClassId.'
';
  // Get the tax rates of each tax class in an associative array
  $taxClasses  = Mage::helper("core")->jsonDecode( Mage::helper("tax")-        
>getAllRatesByProductClass() );
  echo 'Tax Classes '.$taxClasses.'
';
  // Extract the tax rate from the array
  $taxRate   = $taxClasses["value_".$taxClassId];
  echo 'Tax Rate '.$taxRate.'
';
 }
 ?>
