Catalog view -> Add configurable to cart does not work

[marvincaspar]

Hi,

I am on the catalog page and want to quick add a product to the cart. It works fine for single products but not for configurables.

I select a color and a size and click Add to Card. Next I am redirected to the product detail page with the following notification:

You need to choose options for your item.

The selected Item is in stock.

Having the same issue in here. Far I can see there is not detail going on the post to the ajax controller. This affects to the EE edition as well.

I found the problem in the template.
magento2/app/code/Magento/Catalog/view/frontend/templates/product/list.phtml

The form tag is misplaced.

Pull request in here: #2714

Cheers

@matiasnombarasco - I'm still having issues with configurable products and the quick add to cart. I've updated the placement of the form tag and it looks like the values are being posted but the script is redirecting.

Form data being passed to item with one configurable property:
super_attribute[144]: 128, product: 450, uenc: {string}, form_key: {string}

Data gets posted to /{product}?options=cart, and the page returns a 302 Code and redirects to a GET of the same page /{product}?options=cart.

Ironically, at times it does seem to work though on a configurable product. But it's been more like 8/10 times that it won't work. Has the issue returned for you? Perhaps having my frontend completely on SSL may be causing the additional issue for me.

Hi @tigerx7 , that problem didn't happen to me. But for me looks like you are experiencing another issue, not related with this one.

However, looks like the problem might be related with SSL and configuration between secure and insecure urls. I will suggest to check that an also be sure the the ajax urls are under ssl as well. If that doesn't work, is hard to tell what can be the problem.

I will suggest to open another thread and discuss this issue as a separate one and see if someone in the community has the same problem than you.

Good luck!

@matiasnombarasco I think your update on the template definitely fixed half the problem. I did a clean install without SSL to test and sure enough, POST data was missing. I changed the location of the <form> tag, and attributes are now being passed via POST.

However, still was being redirected to product page with "You need to choose options for your item." I found the problem and have been able to reproduce.

Troubleshooting

I happen to come by a configurable product that was actually adding to the cart from the quick add successfully. I compared the items data to one that wasn't working correctly and found a difference in the attributes required_options and has_options.

The one that was working, had both required_options and has_options set to 0. The one that was not working had required_options and has_options set to 1.

I updated the configurable product attribute required_options to 0. After reindexing, I was able to add the configurable product successfully from the quick add to cart in the clean install.

Technically speaking, I'm assuming that indeed configurable products probably should have required_options set to 1? At least I would think so, I'm not sure how the other configurable items had those two attributes set to 0 though. On the production site, items have been added to the catalog via admin and the rest api.

Testing with Clean Install

On the clean install I did to test this, I only added items via admin. I tried both with just clicking "Add Product" which starts it off as a simple product followed by clicking on "Select Configurations" which turns it into a configurable product. I also attempted by clicking "Add Product" -> "Configurable Product" which starts it off as a configurable product directly. I used the already set color attribute, but changed it to a visual swatch prior to creating the products. Both times, the configurable product was created with has_options = 1 and required_options = 1. When testing from the frontend with the correct <form></form> structure, the POST data gets passed but I'm redirected to the product page. However, as soon as I change required_options to 0 and reindex, I'm able to successfully add the product to the cart.

Shorterm Workaround

My short-term solution is going to be to set all the configurable products in the database to required_options = 0; at least until it can be confirmed if this is a bug deeper in the system. Changing this attribute doesn't seem to break "Add to cart" in the product view. Validation still pops up saying fields are required. Only difference I see so far is that add to cart from catalog page now works.

I've kept this reply in this thread since it's still related to the main issue and anyone experiencing this will probably need to both implement #2714 and make sure that the configurable products required_options attribute is set to 0.

I have to confirm that the shorterm workaround of tigerx7 is working. For me, this is a pretty problematic one. Any idea if this will be fixed soon? And is there an easier workaround (maybe skip the required options check somewhere?) instead of going into the database every time?

[TommyKolkman]

Finally "solved" this by setting the value programmatically to 0 in an plugin. In the di.xml of your custom module:

<type name="Magento\Catalog\Model\Product">
    <plugin name="beforeSave" type="Elephant\CFParent\Model\Product" sortOrder="10" disabled="false"/>
</type>

In your own model:

namespace Elephant\CFParent\Model;

class Product
{
   public function afterBeforeSave(\Magento\Catalog\Model\Product $subject, $result)
   {
        /**
         * Temp fix for bug: https://github.com/magento/magento2/issues/2434
         **/

        if( 'configurable' == $subject->getTypeId() ){ 
            $subject->setTypeHasRequiredOptions(false);
            $subject->setRequiredOptions(false);
        }
        return $subject;
   }
}

Good for now, but we need a core fix.

Hi @mc388 you just need to chose all configurable option in configurable product.
If you still have such problems please provide description according to the template, provide the used version, and create new bug.
Closed as not a bug.
