在 WooCommerce 中隐藏特定用户角色的增值税

Question

在 WooCommerce 中，我有一些自定义代码来隐藏特定用户角色的增值税，它适用于所有角色，除了一个名为 Platinum 的角色，它不会隐藏增值税，但仍保持原样所有默认用户角色。

我需要此代码来隐藏铂金的增值税 - 它适用于我列出的其他角色

如何让它也适用于我的“白金”用户角色？

这是我使用的代码：

/**
 * Function that will check for user role and turn off VAT/tax for that role
 */
function wc_diff_rate_for_user() {

    // check for the user role
    if ( is_user_logged_in() && current_user_can( 'bronze', 'sølv', 'guld', 'platinum' ) ) {

        // set the customer object to have no VAT
        WC()->customer->is_vat_exempt = true;
    }

}
add_action( 'template_redirect', 'wc_diff_rate_for_user', 1 );

/**
 * Function that filters the variable product hash based on user
 */
function wc_get_variation_prices_hash_filter( $hash, $item, $display ) {

    // check for the user role
    if ( is_user_logged_in() && current_user_can( 'bronze', 'sølv', 'guld', 'platinum' ) ) {

        // clear key 2, which is where taxes are
        $hash['2'] = array();
    }

    // return the hash
    return $hash;
}
add_filter( 'woocommerce_get_variation_prices_hash', 'wc_get_variation_prices_hash_filter', 1, 3 );

/**
 * Function that removes the price suffix (inc. Tax) from variable products based on role
 */
function wc_get_price_suffix_filter( $price_display_suffix, $item ) {

    // check for the user role
    if ( is_user_logged_in() && current_user_can( 'bronze', 'sølv', 'guld', 'platinum' ) ) {

        // return blank if it matches
        return '';
    }

    // return if unmatched
    return $price_display_suffix;
}
add_filter( 'woocommerce_get_price_suffix', 'wc_get_price_suffix_filter', 10, 2 );

//B2B Roller
add_role('bronze', __(
 'Bronze'),
 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
 )
);

add_role('sølv', __(
 'Sølv'),
 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
 )
);

add_role('guld', __(
 'Guld'),
 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
 )
);

add_role('platinum', __(
 'Platinum'),
 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
 )
);

1) 你的条件函数

第一个 current_user_can() 不建议直接与用户角色一起使用，并且当时只能具有一种能力（或者在您的情况下是一个用户角色）......

在 WooCommerce 3+ 中，您还必须使用 WC()->customer->set_is_vat_exempt( true ); 而不是WC()->customer->is_vat_exempt = true;

您正在使用基于您的特殊用户角色的重复条件函数 3 次。所以我设置了一个可以完美运行的自定义条件函数：

## 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
}

和（你的其他功能）：

## Function that will check for user role and turn off VAT/tax for that role
add_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 user
add_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 role
add_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;
}

代码进入您的活动子主题（活动主题或任何插件文件）的 function.php 文件中。

所有代码都经过测试并且可以工作。

2) 用于创建用户角色

相反，您可以使用出色且非常完整的User Role Editor (free) plugin，这将允许您创建用户角色、微调和检查他们的能力（针对每个创建的角色）。

对于您的用户角色创建代码，您应该只运行一次。我重新审视了它，进行了一些更改并对其进行了压缩。

## 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();

代码进入您的活动子主题（活动主题或任何插件文件）的 function.php 文件中。

不确定代码是如何工作的，因为 current_user_can 函数接受了一个参数： current_user_can function

我会用这段代码重写所有部分：

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

到这样的事情：

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