NOTE: this PR should be test with PrestaShop/PrestaShop#40653 and PrestaShop/PrestaShop#40673 and PrestaShop/PrestaShop#40662

This PR is only a POC to display stock information on the cart page. Core-side changes will be required to properly implement it.

This is a preview of what could be achieved if the core is adapted. I have identified some issues with error messages returned by the core. For example, when a product in the cart is no longer in stock, the current message is something like:
"You can only add 0 qty of this product."

A more appropriate message would be something like:
"Please remove the product (XXX) from the cart." when the available quantity is ≤ 0.

Good start.
On my website, I have an additional display for items that can be ordered if they are out of stock.
Let's imagine an item with 3 pieces in stock. If the customer orders 4 in their cart, I display 3/4 in orange in your example.

@tblivet @Touxten I will make a POC on core. Also handling the partial cases where you order 4 and only 3 are in stock.

Hi @Hlavtox @Touxten, thanks for your work 🙏 I’ll try to have a look at this during the day. Just one thing: I believe both PRs should be pointed to 9.1.x. The one from @Hlavtox is pointed to 9.1.x, but yours @Touxten is pointed to 9.0.x. Ideally, this should be available for 9.1.0 at the same time we release Hummingbird 2.0.0 !

[Touxten]

My PR fixes an existing issue, while Daniel's adds new features.

So my fix will arrive when 9.0.x is merged into 9.1.x.

[Hlavtox]

@tblivet Good, let me know what you think! :-)

And yes, @Touxten PR is a fix for all themes, not related to hummingbird or 9.1.

[tblivet]

@Hlavtox That’s my bad, I messed up in my PR and was using submessage instead of delivery_time. I’ve just pushed a fix 👍

[Hlavtox]

@tblivet The code for delivery is actually a bit more complicated, because the core doesn't provider proper data.

But, it can be simplified both in cart and on product, page, if this PR gets merged - PrestaShop/PrestaShop#40673.

[tblivet]

@Hlavtox OK, you handle all the logic on the PHP side, in fact, it would be much more cleaner in the FO 👍
I’ll update this POC to also update this section and add in the description all the PRs that need to be merged with this one.

[Hlavtox]

😍😍😍

[Hlavtox]

One last tweak, I will reapprove immediately 🙏

And one question @tblivet @ga-devfront - guys, why is there the condition to put hidden? Isn't the block automatically rendered and replaced as a whole? Cannot we just not render it at all if both availability and delivery message is missing?

[tblivet]

@Hlavtox I pushed a fix. Is this what you were asking? I’m not 100% sure.

The hidden attribute is for design purposes because the element is always on the page and has a margin. If we don’t use hidden, we’ll end up with a sort of double margin if the block is present but empty, which is something we don’t want.

Without :

With hidden :
