Hide VAT for specific user roles in WooCommerce

Update 2

1) Your conditional function

First current_user_can() is not recommended to be used with user roles directly and can only have one capability (or in your case one user role) at the time…

Also in WooCommerce 3+ you will have to use WC()->customer->set_is_vat_exempt( true );instead of WC()->customer->is_vat_exempt = true;

You are using a repetitive conditional function based on your special user roles 3 times. So I have set a custom conditional function that should work perfectly:

## The (repetitive) conditional function based on your "special" user roles function is_special_user_role(){    if ( ! is_user_logged_in() ) return false;    $user = wp_get_current_user(); // current user    $user_roles = $user->roles; // It's always an array (as a user can have many roles)    // HERE your defined user roles    $defined_user_roles = array( 'bronze', 'sølv', 'guld', 'platinum' );    if ( count( array_intersect( $user_roles, $defined_user_roles ) ) > 0 ) return true;    else return false; // ==> Added update here}

And (your others functions):

## Function that will check for user role and turn off VAT/tax for that roleadd_action( 'template_redirect', 'wc_diff_rate_for_user', 1 );function wc_diff_rate_for_user() {    // check for the user role and set the customer object to have no VAT    if ( is_special_user_role() )        WC()->customer->set_is_vat_exempt( true ); // Updated HERE}## Function that filters the variable product hash based on useradd_filter( 'woocommerce_get_variation_prices_hash', 'wc_get_variation_prices_hash_filter', 1, 3 );function wc_get_variation_prices_hash_filter( $hash, $item, $display ) {    // check for the user role and clear key 2, which is where taxes are    if ( is_special_user_role() )        $hash['2'] = array();    return $hash; // return the hash}## Function that removes the price suffix (inc. Tax) from variable products based on roleadd_filter( 'woocommerce_get_price_suffix', 'wc_get_price_suffix_filter', 10, 2 );function wc_get_price_suffix_filter( $price_display_suffix, $item ) {    // check for the user role return blank if it matches    if ( is_special_user_role() )        $price_display_suffix = '';    return $price_display_suffix;}

Code goes in function.php file of your active child theme (active theme or in any plugin file).

All code is tested and works.

2) For your user roles creation

Instead you could use the excellent and very complete User Role Editor (free) plugin, that will allow you to create user roles, fine tune and check their capabilities (for each created role).

For your user roles creation code, you should run it only once. I have revisited it, making some changes and compacted it.

## Special user roles creation ==> this should be runned just once!function special_ser_role_creation(){    // Your "Special" user roles slug / name pairs    $special_roles_array = array(        'bronze'   => __( 'Bronze' ),        'sølv'     => __( 'Sølv' ),        'guld'     => __( 'Guld' ),        'platinum' => __( 'Platinum' ),    );    $roles_caps = array(        'read'          => false, // Allows a user to read        'create_posts'  => false, // Allows user to create new posts        'edit_posts'    => false, // Allows user to edit their own posts    );    $existing_user_roles = array_keys( wp_roles()->get_names() );    // Iterating through each user roles and create them    foreach( $special_roles_array as $role_slug => $role_name ){        // If user role doesn't exist yet we create it        if (! in_array( $role_slug, $existing_user_roles) )            add_role( $role_slug, $role_name, $roles_caps );    }}// Run the function once (then comment it or remove it)special_ser_role_creation();

Code goes in function.php file of your active child theme (active theme or in any plugin file).

Not sure how the code is working because the function current_user_can takes in one parameter:current_user_can function

I would rewrite all sections with this code:

    if ( is_user_logged_in() && current_user_can( 'bronze', 'sølv', 'guld', 'platinum' ) ) {

To something like this:

    if ( is_user_logged_in() && ( current_user_can( 'bronze' ) || current_user_can( 'sølv' ) || current_user_can( 'guld' ) || current_user_can( 'platinum' ) ) ) {
