Amazing PrestaShop Project: Disable attribute out of stock with currently attribute in product prestashop 1.7

You know, Leotheme is one of the best provider marketplaces in PrestaShop for PrestaShop Themes, PrestaShop Module & Custom Work.

At present, we have a lot of power customization projects in PrestaShop. And today, we are pleased to introduce our project and we would like to share tips for all. Hope that this blog will help you well.

Firstly, the fact that Prestashop has the option to hide attribute doesn’t exist.
For example: You have size (36,37,38,39) and color (red, blue).
If you don’t input size 36 with red color. Prestashop has option PS_DISP_UNAVAILABLE_ATTR, if you turn on it, the red color will not display when you click on size 36.
That is very good, but that is not enough.

3 days ago, I got this request of my customer.

So far, all of our products have had only one variation, the shoe size. In the back office, I have activated that only existing variants are displayed on the article page. This works even if the Product has only one variant.

Now we have products with two variants (color and size) and unfortunately, the automatic filtering does not work anymore.
If the customer chooses a color, then only the available sizes should be displayed, but also unavailable sizes are displayed. If the customer then selects, he jumps to another hue. Not existing sizes are not filtered out. The customer should only see existing variationsAnother possibility is that non-existent combination are deactivated by a cross.

So I use 3 days to research it.
And I have to add my code to the Prestashop core to solver it.
If you are a developer, you can follow my code to add this function, it will help your site run perfectly.
I edit function assignAttributesGroups in controller/font/ProductController.php.


protected function assignAttributesGroups($product_for_template = null)

Note: remove

and

that is wordpress 🙁

you can see, I add class=”disable” for attribute have quantity =0

In theme.css file

you only need add code at the end of file

.product-variants > .product-variants-item ul li label.disable{display:none}

 

You can see demo of my customer website

If you are a developer I can make sure you can do it.
