如何使用woocommerce从管理产品页面显示/隐藏某些类别？

Question

I've been trying to do this for a time, unfortunately I've found only solutions for the store(frontend) in cases the category is empty and so on.

What I basically want to do, is when I create a new product, at the Prodct Categories section

I want to show/hide some categories.

So far I haven't found anything for this, any idea how can it be done?

Thanks.

Try out below code :

function is_edit_page($new_edit = null){
    global $pagenow;
    //make sure we are on the backend
    if (!is_admin()) return false;

    if($new_edit == "edit")
        return in_array( $pagenow, array( 'post.php',  ) );
    elseif($new_edit == "new") //check for new post page
        return in_array( $pagenow, array( 'post-new.php' ) );
    else //check for either new or edit
        return in_array( $pagenow, array( 'post.php', 'post-new.php' ) );
}


function so_28055266_filterGetTermArgs($args, $taxonomies) {
    global $typenow;

    if ($typenow == 'product') { 
        // check whether we're currently filtering selected taxonomy
        if (implode('', $taxonomies) == 'product_cat' && is_edit_page()) {
            //Add categories term ID that you want to show
            $cats = array(9,10,11,12); // List of category(term ID) that you want to add as an array

            if (empty($cats))
                $args['include'] = array(99999999); // no available categories
            else
                $args['include'] = $cats; //It will only show the category that you mentioned in above array
        }
    }

    return $args;
}

if (is_admin()) {
    add_filter('get_terms_args', 'so_28055266_filterGetTermArgs', 10, 2);
}

Let me know the output.
