php - WooCommerce 产品 : Allow backorders only for specific user roles

Question

我想允许特定客户角色的延期交货。我写的代码是:

// BackOrder Allow Part #1
add_filter( 'woocommerce_product_backorders_allowed', 'woocommerce_product_backorders_allowed', 10, 3 );
function woocommerce_product_backorders_allowed( $backorder_allowed, $product_id, $product ){
    if ( current_user_can('administrator') ) {
        $backorder_allowed = true;
    } else {
        $backorder_allowed = false;
    }

    return $backorder_allowed;
}

// BackOrder Allow Part #2
add_filter( 'woocommerce_product_get_stock_status', 'woocommerce_product_get_stock_status', 10, 2 );
function woocommerce_product_get_stock_status( $stock_status, $product ) {
    if ( current_user_can('administrator') ) {
            return 'onbackorder';
    }
    else {
        return 'outofstock';
    }
    
}

这个给出的结果似乎只适用于简单的产品。我如何为其他产品类型工作。我需要为简单、可变和 yith-bundle 工作。任何帮助将不胜感激!谢谢!

您的代码中存在一些错误和缺失。请改用以下内容:

// Custom conditional function targeting specific user roles
function is_allowed_user_role() {
    $targeted_roles = array('administrator', 'shop_manager'); // Here define your targeted user roles
    return (bool) array_intersect( wp_get_current_user()->roles, $targeted_roles );
}

add_filter( 'woocommerce_product_get_stock_status', 'filter_product_stock_status' );
add_filter( 'woocommerce_product_variation_get_stock_status', 'filter_product_stock_status' );
function filter_product_stock_status( $stock_status ) {
    if ( ! is_allowed_user_role() && 'onbackorder' === $stock_status ) {
        $stock_status = 'outofstock';
    }
    return $stock_status;
}

add_filter( 'woocommerce_product_get_backorders', 'filter_product_get_backorders' );
add_filter( 'woocommerce_product_variation_get_backorders', 'filter_product_get_backorders' );
function filter_product_get_backorders( $backorders ){
    return is_allowed_user_role() ? $backorders : 'no';
}

add_filter( 'woocommerce_product_backorders_allowed', 'filter_product_backorders_allowed', 10, 3 );
function filter_product_backorders_allowed( $allowed, $product_id, $product ){
    return is_allowed_user_role() ? $allowed : false;
}

代码进入事件子主题(或事件主题)的 functions.php 文件。经过测试并有效。
