invoice How to check if combination selected in the order is not the default

[Dissolved Fractals]

Hi,

I am trying to modify the invoice template that prints out pdf to know if the order has selected anything other than the default combination. If it is not the default combination, it will do some html/css modifications. Otherwise, leave as is. My two questions are:

1. What is the variable to check if the combination selected in the order is the default or not

2. The product title + the combination can be retrieved using { $order_detail.product_name }, how do I retrieve them separately so I can do modifications on the combination part alone?

 

Additional question: Since the only way for me to check the changes is viewing the pdf file, is there a way for me to view it in html format for quick testing?

In order to do this you need to overwrite the file

classes/pdf/HTMLTemplateInvoice.php

And inside public function getContent()

Add this

foreach ($order_details as &$order_detail) {
$product = new Product($order_detail['product_id'], false, Context::getContext()->language->id, Context::getContext()->shop->id);
$has_combinations= $product->hasCombinations();
$id_default_attribute = (int) Product::getDefaultAttribute($order_detail['product_id'], 0, true);
$order_detail['is_default_attribute'] = ($has_combinations && (int)$order_detail['product_attribute_id'] == (int)$id_default_attribute) ? true : false;
 }

Then in 

/pdf/invoice.product-tab.tpl

You can use the variable and or statement

{if $order_detail.is_default_attribute} ........ {/if}

Thanks. What is left now is from my 2nd question so I can do this:

{ product_title } {if $order_detail.is_default_attribute} ........ {else} {product_attribute} {/if} .

To explain further, how do I break down { $order_detail.product_name } so I can separate product attribute(combination) from the product title?
