Breadcrumb issue when translating with Falang

-- url of the page with the problem -- : test server
-- HikaShop version -- : 2.6.2
-- Joomla version -- : 3.6.2
-- PHP version -- : 5.6
-- Browser(s) name and version -- : Any

We building a test site with English and Spanish (with Falang) We ran into an issue when scrolling backwards and forwards with products that were in more than one category (irrespective of language selected). So for example we have the following category structure in Hikashop

Company Name -> Product Line 1 -> SubCategory 1
Company Name -> Product Line 1 -> SubCategory 2

We then have menu menu links starting with Product Line 1 then two submenu links to SubCategory 1 and SubCategory 2

We find that if you go to if you have a product that is both Subcategory 1 and Subcategory 2, if you go to Subcategory 1 and then view the single product pages and scroll backwards and forwards when you get the product which is in both categories then instead of scrolling products just in Subcategory 1 you then have products from Subcategory 2 and vice versa.

We found that if we set in the datashop configuration -> SEF url options -> Simplified breadcrumbs to NO, so now the URL now has category_pathway-## the problem was resolved. Scrolling backwards and forwards we just see the products in Subcategory 1, or Subcategory 2 are shown.

However changing Simplified Breadcrumbs to NO created another problem. We have the website with English the base language then translated in Spanish. Viewing the products in English everything show correctly. However if you view the products in Spanish the Breadcrumb show incorrectly.

So if we are view a product in subcategory 1 the breadcrumb in English is:

Home > Product Line 1 > SubCategory 1 -> Product Name

In Spanish it becomes (obviously translated in Spanish)

Home > Product Line 1 > SubCategory 1 > Company Name > Product Line 1 > Subcategory 1 > Product Name

So in the breadcrumb we have the menu structure plus the hikashop cateogry structure.

Setting Simplified Breadcrumbs to YES the breadcrumb structure in Spanish returns to normal

Home > Product Line 1 > SubCategory 1 -> Product Name

but then we have problem again of scrolling backwards and forwards when you get to product in more than one category.

Is there something we can change in the settings to resolve this issue(s)?
Thanks, J

We'll set Simplified Breadcrumbs to YES the NO and look at what data is called scroll through the products in each case and see if we can find a way of setting simplified Breadcrumbs to YES and just viewing products in the same category and the we'll report back, with screenshots and other info as necessary.

Hi Nicolas,

I apologise for not replying before but we needed a moment to look at the issue further and we have found a solution to our issues but it required a hack of the source code. We have tested with Hikashop 2.6.4 and Falang 2.7.0 on Joomla 3.6.4.

To recap in our setup we have several products we are assigned to multiple categories. The category views work correctly and the product listings work correctly. The problem was when you viewed a single product and then clicked on the links to scroll though to view other products in the same category. At a certain point it would jump from the current category and begin showing products from a different category.

We kind of solved the problem by going into the configuration in the SEF url section and setting simplified breadcrumbs to "No". It solved the problem in English which is the default language but in other languages the breadcrumb was screwed up. It basically contained repetitions of itself.

So we went back and set simplified breadcrumbs to "Yes" and had a look at the code in com_hikashop/views/product/view.html.php in the frontend and we see in line 1537 this if $category_id is empty it then looks up the category with loadResult() call which just returns a single result. So if a product is assigned to multiple categories this query does not take that into consideration. However the category id is also stored under the menu item params so we added a couple lines of code

if (!empty($menuData->hikashop_params['category']))
				{
					$category_id = $menuData->hikashop_params['category'];
				}				

if(HIKASHOP_J30 && !in_array(@$_REQUEST['option'],array('com_falang','com_joomfish'))){

if(HIKASHOP_J30 && !in_array(@$_REQUEST['option'],array('com_joomfish'))){

$menuData->hikashop_params['category'];

Hi Nicolas,

1) I have changed the subject because we have set "simplified breadcrumbs" to yes, and the issue we now have is how to display the correct products when scrolling through the product views in a category when one or more products in that category are also assigned to another category. When scrolling through the products, when you arrive at a product which is assigned to more than one category, if $category_id with this database query

			if(empty($category_id)){
				$query='SELECT a.category_id FROM '.dacshop_table('product_category').' AS a WHERE a.product_id='.(int)$product_id.' ORDER BY a.product_category_id ASC';
				$database->setQuery($query);
				$category_id = $database->loadResult();
				$filters['category'] = 'a.category_id = '.(int)$category_id;
			}

That is clear now which one comes out now. We will try re-ordering the categories to see if we can find a solution.
