how to pick up woocommerce attributes

If I understand you correctly you want to show the size attribute? Can you show me an example of exactly what you want?

That’s it.

This screenshot I took from another store.

At the top appears a product brand, then the product and final size – See the image: https://snag.gy/ItaePx.jpg

My store has two types of preview:

Desktop version: https://snag.gy/RmYzNi.jpg

Mobile version: https://snag.gy/c5xGIn.jpg

In the mobile version, I would like to show only the size.

Just so if I understand you correctly you want this

To be on your

page (cuz I don’t see a size) and show on mobile too?

Correct?

Almost that. In that case, you entered the product. This size you showed I had to type.

I want before the customer enters the product, in the visualization of the shop, already have this information of size.

I’m filtering on the site, so I already set a size attribute for each product, I just need to know how to invoke it.

Understood.

So what you want to do is very complex and would be outside of this forum’s support. This forum is for WC core support and does not deal with customization. What you want done involves a lot of code just to achieve that final outcome. It is doable but best you reach out to a developer that can assist you in this.
