Removing functions from Woocommerce hooks

Question

This will probably open a door for me as there's something I'm missing so a WooCommerce 101 please;

part of the WooCommerce template archive-product.php contains the code;

    <?php
            /**
             * woocommerce_before_shop_loop hook.
             *
             * @hooked woocommerce_result_count - 20
             * @hooked woocommerce_catalog_ordering - 30
             */
            do_action( 'woocommerce_before_shop_loop' );
        ?>

From this, and reading the documentation, it implies that this;

remove_action( 'woocommerce_before_shop_loop', 'woocommerce_result_count', 20 );

should remove the result count from the product categories returned. Only it doesn't.

What's wrong?

Solution 1

I was going to say you should read the documentation but it is leaving an important part out.

remove_action() cannot be called directly and must, itself, be added to an action hook. The action hook needs to come before the action being removed. In this case I would just use the same hook, but an earlier priority (default is 10, I've used 1)

function so_38878702_remove_hook(){
   remove_action( 'woocommerce_before_shop_loop', 'woocommerce_result_count', 20 );
}
add_action( 'woocommerce_before_shop_loop', 'so_38878702_remove_hook', 1 );

Solution 2

To remove result count action from Woocommerce -

add_action('woocommerce_before_shop_loop', 'remove_result_count' );
    function remove_result_count()
    {
         remove_action( 'woocommerce_before_shop_loop', 'woocommerce_result_count', 20);
      
    }

use this code in your function.php file.

Important: To remove a hook, the $function_to_remove and $priority arguments must match when the hook was added. This goes for both filters and actions. No warning will be given on removal failure.

Thank you, I'm beginning to understand this important technique now. And it's true that it is not mentioned in the Wordpress documentation.

I just added it to the Codex. Though I think they are moving over to developer.wordpress.org.
