Problems with breadcrumbs

[susmithaN]

Preconditions

I have some problems with breadcrumbs .
Im using

1. Magento ver. 2.1.1
2. PHP Version 7.1.0

Steps to reproduce

1. Open Product from list page
   List page - http://prnt.sc/doeoxy

Expected result

1. details page should contain breadcrumbs in this format Home -> Category name ->Product Name

   Home > Proteasome Inhibitors > MG-132

Actual result

1. Home > MG-132 - Category missing
   Detail page - http://prnt.sc/doeqa2

Is it possible to get full breadcrumb with Magento 2 ?

[susmithaN]

Hi ,

Steps to reproduce

1 . GO to category page (product list page ) from home page .
2 . From category page to product detail page .
3 . On product detail page , breadcrumbs looks like Home > Product name
But the expected result is Home > category name > product name

Hi , Kindly let us know if any updates regarding this issue .

[susmithaN]

Is there any updates regarding this issue ?

[susmithaN]

Anyone have any idea about this issue ?

[ghost]

Just made an update to version 2.1.4 via web wizard, still got those broken breadcrumbs.

[susmithaN]

Hi ,
I have checked this issue on Latest version , There also i faced the same breadcrumbs issues. I Found an option to add category with product url from back end . Once enabled it Breadcrumbs with category displayed on product detail page . But If I open the same product from any other page like home , search , its not displaying full breadcrumbs . Just showing Home-> product name . Can you please suggest any solution for this .

PHP Version 7.1.0

Is it correct? This PHP version is not supported yet.

Is issue reproducible when you disable caches?

[ghost]

I am on PHP Version 5.3.6 and Magento 2 Version 2.1.4. Issue occures even with cache disabled. Dev and production mode are equally affected.

Hi , Anyone have any suggestion to solve this issue .

[susmithaN]

Hi , Please let me know if you have any suggestion regarding this issue.

[akosglue]

Hi @susmithaN , disclaimer: this is just an idea for a workaround and not yet tested completely, but maybe you can get a hint from it:

• if you override _prepareLayout() in \Magento\Catalog\Block\Breadcrumbs in your custom module
• add this in the beginning:
  $product = $this->registry->registry('current_product'); if($product != null){ $cats = $prod->getAvailableInCategories(); end($cats); $last = prev($cats); $categ = $this->_repository->get($last); $this->registry->register('current_category',$categ, true); }
  This basically adds the missing category 'manually' to the registry.

[susmithaN]

Hi , Thank you for your information . I tried this one . But Still got the same problem . I cant able to add missing categories on registry .

[susmithaN]

Hi , Any other suggestion to solve this problem .

This was the case in M1 as well, if you had "Use category path for product URL" set to "No" https://www.creare.co.uk/wp-content/uploads/2014/03/fdf-2-658x328.jpg

Only with category path in URL, Magento could resolve which category should be in breadcrumbs path. This sure is unfortunate, but don't believe it's a bug, as we cannot simply guess what category to show at the top, unless we add some sort of query parameter to URL that would identify which category the product was accessed from.

[orlangur]

we cannot simply guess what category to show at the top, unless we add some sort of query parameter to URL

If a product belongs to only one category, we can use it in breadcrumbs. However, if in this issue Use category path for product URL = "No" it would be not correct to change breadcrumbs this way as breadcrumbs should reflect site navigation, not some random stuff.

[sambolek]

Exactly.
I'm thinking that having inconsistent breadcrumbs, where we show a category path if product is in only one caregory, and nothing (or random/last assigned category) if it's in multiple categories would be more hurtful than this.

Presume we have two choices here:

1. Leave it as is, but maybe describe in documentation what are the consequences of setting "Use category path for product URL" to " No"
2. Figure out a way of implementing history-based breadcrumbs that work with Varnish/FPC (there were some M1 extensions that relied to HTTP referrer, but that would introduce another layer of problems with caching)

To conclude, this is more of a feature request than a bug report.

[susmithaN]

Thank you for the information ,

but don't believe it's a bug, as we cannot simply guess what category to show at the top, unless we add some sort of query parameter to URL that would identify which category the product was accessed from.

Fine but why do I sometimes get a full breadcrumb when I follow my category up to the product from the front page and sometimes not? That makes no sense.

[MattSewing]

Totally agree with salacis

I have the same problem, one moment i have full category path - the next i don't.

Sometimes I can have the full path in the breadcrumb, 5 mins later I can refresh the page, and it changes.

[mbahar]

As a solution;
To override the inconsistent behaviour, I override the block;
Magento\Catalog\Block\Breadcrumbs

with the following;

[BigTonni]

I have a same issue with 2.1.6. Still looking for a solution.

[jonahellison]

Breadcrumbs use catalog session data (the last category the user viewed) for rendering, which seems to be a flaw since this is then cached and displayed to other users.

One workaround is to use another event observer (such as layout_load_before) along with #7967 (comment) to remove this data:

        // @var \Magento\Catalog\Model\Session $catalogSession
        $this->catalogSession
            ->unsetData('last_visited_category_id')
            ->unsetData('last_viewed_category_id');

[magefan]

Based on @novakivskiy suggestion we have created a temporary solution magefan/module-catalog.

You can simply install it via composer

Has this issue been fixed in any 2.1 version? I am also currently experiencing this in 2.1.10- Products will show home > category > category > product name and then after some time it just shows home > product name.

[subbu1993]

Hello - @magento-engcom-team

Is there an update on this issue ?

Can we expect a fix anytime soon ?

[sambolek]

since 2.2.3 breadcrumbs are a JS widget that relies on page referer to get category path https://github.com/magento/magento2/blob/2.2-develop/app/code/Magento/Catalog/view/frontend/web/js/product/breadcrumbs.js

[orlangur]

@susmithaN @magento-engcom-team looks like the issue is fixed in 2.2.x.

[MattSewing]

Hi Guys As the author of this post, I have come to the conclusion a year on, that it cannot be done. I am not a programmer. But I have asked a lot of programmers the question and have drawn a blank. After some investigation, I believe this extension will sort the issue out: https://amasty.com/unique-product-url-for-magento-2.html We will be launching this extension as part of a bigger upgrade later this month… after using the demo I see no reason why this won’t work for our website too.

@MattSewing,

As the author of this post, I have come to the conclusion a year on, that it cannot be done

Well, any kind of logic can be done :) But without referer and if product can be assigned to more than one category, logic is really not clear to me.

[LucScu]

@magento-engcom-team @orlangur please close this issue, because it is not an issue.
It is clear that without a referer or parametrized url is not possible to construct the complete product's breadcrumbs with categories.

[magento-engcom-team]

Closing. Thank you

[Yamaha32088]

The problem appears to be a typo in this file

magento2/app/code/Magento/Catalog/ViewModel/Product/Breadcrumbs.php

Line 108 in 0eb8677

'userCategoryPathInUrl' => (int)$this->isCategoryUsedInProductUrl(),

it should be useCategoryPathInUrl instead because

magento2/app/code/Magento/Catalog/view/frontend/web/js/product/breadcrumbs.js

Line 17 in 0d99623

useCategoryPathInUrl: false,

is looking for it

[sidolov]

Hi @susmithaN. Thank you for your report.
The issue has been fixed in #19760 by @Yamaha32088 in 2.2-develop branch
Related commit(s):

• bf7ee62ea3be3998c5f34fb0e7410412e79c5c6f

The fix will be available with the upcoming 2.2.9 release.

[robertbaum]

yes I saw that the issue caused by the cache when someone opens the product from the search or from a custom widget the product page will be opened without category breadcrumbs and as well will be cached as it
