@magento-engcom-team Yes, i can confirm that the bug is reproducible on the vanilla Magento instance

Reason: The "return" key invokes the submit action of the Form. The "submit" action is bound to the Button "Clear Shopping Cart".

@akimo I am not able to reproduce this issue based on provided steps on current magento 2.3-develop instance let me know if it requires any additional step to reproduce the issue

[akimo]

This issue is new in 2.3.1 and not present in 2.3.0 (I don't know which version "2.3-develop" is based on). You need to press the return key while the cursor is still in the quantity field.
The Problem is caused by the Button "Clear Shopping Cart" which is of type="submit". If you press return the form will perform a "submit".

[chichitsai0517]

I have exactly the same issue! I installed a fresh copy of Magento 2.3.1 with sample data just to test and like you mentioned, the cart empties after hitting the "ENTER" key.
I would really love to find a way to fix this!

@magento-engcom-team give me 2.3-develop instance

Hi @Mobecls. Thank you for your request. I'm working on Magento 2.3-develop instance for you

[magento-engcom-team]

Hi @Mobecls, here is your Magento instance.

@akimo - wasn't able to reproduce it neither on 2.3-develop, nor on 2.3.1 latest official release.

1. Added product to a cart (10 pcs)
2. Proceeded to a cart page
3. changed product qty to 5 and hit "update shopping cart"
4. clicked on browser Return button (verified on latest Chrome and Safari on Mac).

The shopping cart had 5pcs (no products were flushed from a cart)...

[chichitsai0517]

Hi, this is weird. Is this 2.3.1? I have a website upgraded from 2.2.6 to 2.3.1 that does that. So I installed a fresh copy of the magento 2.3.1 with sample data and it also does the same. Am I able to message someone with the the cpanel and admin credentials to see?

[Mobecls]

@chichitsai0517 please, see if you can reproduce it here - https://i-22137-2-3-develop.instances.magento-community.engineering it's still up and running.

[chichitsai0517]

Hi Mobecls, I tried on yours and it does not do the same as mine. I don't understand because my test website has no extensions and no themes. It is the original 2.3.1 with sample data.

[Mobecls]

@chichitsai0517 - that's our latest environment, so if it is not getting reproduced there - it's either an environment issue. If you don't have any additional info on how to reproduce it here - please, close the issue.

[chichitsai0517]

Do you think this is a PHP Version issue? I just checked on my hosting account and they only have PHP 7.1.27 or 7.2.16.
I am using PHP 7.2.16.
However on Magento 2.3.X Stack technology requirements, it says that we should be using PHP 7.2.11

[hostep]

I can very easily reproduce this as well on a vanilla Magento 2.3.1 installed using composer. This isn't an environment issue.
@Mobecls: your steps to reproduce are incorrect. You shouldn't press the Update Shopping Cart button, you should simply increase the qty of an item in the cart and then press the enter/return key while the focus of your cursor is still in the qty field to confirm the change.

[hostep]

This is fixed in 2.3-develop however, and I've found a PR which fixes it: #21509

So we can close this issue, since it duplicates #21499 and was fixed by #21509 and the fix should get released in Magento 2.3.2 & 2.2.9.

If you still have this issue you have to know that on a html form the first element witch has type submit on it will be called when "enter" is hit. So in magento the first element on the form with type submit is the clear button. To solve this issue you can modify the order of the buttons in Magento_Checkout/templates/cart/form.phtml ( put update button before clear button)
