ganalytics.php: track reductions as custom metric in ga-ecommerce-reports

[zac]

Hi there,

 

I'd like to track reduction per product as custom metric on order confirmation. Eg. a product normally sold for $100 is on sale with 25% discount, I want to track the $25 reduction.

 

Therefore I edited in ganalytics.php (Modul ganalytics, V2.3.1) the public function wrapProduct , in specific the $ga_product array (around line 530)

So 

$ga_product = array(
				'id' => $product_id,
				'name' => Tools::jsonEncode($product['name']),
				'category' => Tools::jsonEncode($product['category']),
				'brand' => isset($product['manufacturer_name']) ? Tools::jsonEncode($product['manufacturer_name']) : '',
                                //'brand' => Tools::jsonEncode($product['manufacturer_name']),
				'variant' => Tools::jsonEncode($variant),
				'type' => $product_type,
				'position' => $index ? $index : '0',
				'quantity' => $product_qty,
				'list' => Tools::getValue('controller'),
				'url' => isset($product['link']) ? urlencode($product['link']) : '',
				'price' => number_format($product['price'], '2')
			);

is now:

$calc_discount = $product['price_without_reduction'] - $product['price'];
                        $ga_product = array(
				'id' => $product_id,
				'name' => Tools::jsonEncode($product['name']),
				'category' => Tools::jsonEncode($product['category']),
				'brand' => isset($product['manufacturer_name']) ? Tools::jsonEncode($product['manufacturer_name']) : '',
                                //'brand' => Tools::jsonEncode($product['manufacturer_name']),
				'variant' => Tools::jsonEncode($variant),
				'type' => $product_type,
				'position' => $index ? $index : '0',
				'quantity' => $product_qty,
				'list' => Tools::getValue('controller'),
				'url' => isset($product['link']) ? urlencode($product['link']) : '',
				'price' => number_format($product['price'], '2'),
                                'metric1' => number_format($calc_discount, '2')
			);

In Google Analytics I defined a new custom metric (Index: 1, scope: product, format: currency) - I also tried hit-scope and integer combinations, all without success.

 

According to Google help center it is definitely possbile and allowed to track custom metrics with transactions

 

Source code on order-confirmation looks fine, still my metric in GA-reports is 0 - although all my test-orders were all  reduced products.

 

Any hints for me whats wrong?

Thanks in advance, Chris
