Fix WooSell class resolution in PPOM\Support\Helpers

[Copilot]

Product pages could fatally error when WooSell Wholesale Prices is active because Helpers.php is namespaced (PPOM\Support) but WooSell classes were referenced without global namespace qualification. PHP attempted to resolve them as PPOM\Support\WWP_*, which does not exist.

• Changes
  • Namespace-safe WooSell calls in get_product_price()
    • Prefixed WooSell class references with \:
      • \WWP_Wholesale_Roles
      • \WWP_Wholesale_Prices
      • \WWP_Helper_Functions
  • Namespace-safe WooSell call in get_product_regular_price()
    • Prefixed WWP_Wholesale_Roles with \ in wholesale role lookup.
  • Scope
    • Only these class references were updated; no logic or behavior outside class resolution was changed.

// Before
$wwp_roles           = WWP_Wholesale_Roles::getInstance();
$price_arr           = WWP_Wholesale_Prices::get_product_wholesale_price_on_shop_v3(
    WWP_Helper_Functions::wwp_get_product_id( $product ),
    $user_wholesale_role
);

// After
$wwp_roles           = \WWP_Wholesale_Roles::getInstance();
$price_arr           = \WWP_Wholesale_Prices::get_product_wholesale_price_on_shop_v3(
    \WWP_Helper_Functions::wwp_get_product_id( $product ),
    $user_wholesale_role
);

Original prompt

Bug

A fatal error occurs on product pages when the WooSell Wholesale Prices plugin is active:

Fatal error: Uncaught Error: Class "PPOM\Support\WWP_Wholesale_Roles" not found
in src/Support/Helpers.php on line 166

Root Cause

src/Support/Helpers.php is declared in the PPOM\Support namespace. The methods get_product_price() (lines ~164–173) and get_product_regular_price() (lines ~208–213) reference three third-party classes — WWP_Wholesale_Roles, WWP_Wholesale_Prices, and WWP_Helper_Functions — without a leading backslash. PHP therefore tries to resolve them as PPOM\Support\WWP_*, which don't exist, causing a fatal error.

Fix

In src/Support/Helpers.php, prefix all three class names with \ so they resolve from the global namespace:

In get_product_price() (~line 164):

// Before
if ( method_exists( 'WWP_Wholesale_Prices', 'get_product_wholesale_price_on_shop_v3' ) ) {
    $wwp_roles           = WWP_Wholesale_Roles::getInstance();
    $user_wholesale_role = $wwp_roles->getUserRoles();
    $price_arr           = WWP_Wholesale_Prices::get_product_wholesale_price_on_shop_v3( WWP_Helper_Functions::wwp_get_product_id( $product ), $user_wholesale_role );

// After
if ( method_exists( 'WWP_Wholesale_Prices', 'get_product_wholesale_price_on_shop_v3' ) ) {
    $wwp_roles           = \WWP_Wholesale_Roles::getInstance();
    $user_wholesale_role = $wwp_roles->getUserRoles();
    $price_arr           = \WWP_Wholesale_Prices::get_product_wholesale_price_on_shop_v3( \WWP_Helper_Functions::wwp_get_product_id( $product ), $user_wholesale_role );

In get_product_regular_price() (~line 208):

// Before
if ( has_filter( 'wwp_filter_wholesale_price' ) ) {
    $user_wholesale_role = WWP_Wholesale_Roles::getUserRoles();

// After
if ( has_filter( 'wwp_filter_wholesale_price' ) ) {
    $user_wholesale_role = \WWP_Wholesale_Roles::getUserRoles();

Only these specific class name references need changing — no other logic should be modified.
