Hide product attributes from additional information tab in WooCommerce

Question

How to hide certain custom product attributes on single product pages additional informations tab?

Note: I don´t want to hide everything, just specific attributes.

For e.g i would like to hide "pa_size" to name one it it.

Only found this one, but its for a products weight.

add_filter( 'woocommerce_product_get_weight' , '__return_false' );

Answer 1

For all custom product attributes you can hide them from additional information tab just deselecting the option "Visible on the product page" under product settings > Attributes tab:

1) To remove the product dimensions, you can disable that with the following code:

add_filter( 'woocommerce_product_get_dimensions', '__return_false' );

2) To remove everything from the tab ( weight, dimensions and custom attributes) use this:

remove_action( 'woocommerce_product_additional_information', 'wc_display_product_attributes', 10 );

3) To fine tune what you want to display:

You can override single-product/product-attributes.php template via your active child theme (or active theme) that displays everything in this product tab.

So you can remove any html block, that displays those details, or customize it…

Answer 2

Using the functions.php can cause problems with shipping, see here: https://github.com/woocommerce/woocommerce/issues/5985#issuecomment-322541850

Simply copy the wp-content/plugins/woocommerce/templates/single-product/product-attributes.php to wp-content/themes/YOUR_CHILD_THEME/woocommerce/single-product/product-attributes.php and add an if to check for the attribute. (As LoicTheAztec mentioned in #3)

This is from WooCommerce 4.4.1:

<?php
/**
 * Product attributes
 *
 * Used by list_attributes() in the products class.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/product-attributes.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce/Templates
 * @version 3.6.0
