在特定日期销售特定 Woocommerce 商品，在特定时间范围内销售其他商品

Question

我之前问过是否可以限制特定物品只能在周日购买，并且 "Sell some products only on a specific day in WooCommerce" 提供的答案代码效果很好......

我现在有一些可以在任何一天购买的物品，但只能在伦敦时间下午 12:00 到 2.30 之间购买。

您能帮忙修改以前的代码以允许这样做吗？

注意：我仍然想运行 LoicTheAztec 之前的代码，因为某些项目仍然仅限于周日。

Answer 1

以下代码将允许在周日购买特定物品，并在时间范围内（12h 到 14h30）购买特定物品。

这是这2个答案代码的组合：

• Sell some products only on a specific day in WooCommerce
• Enable Woocommerce shop purchases only during a daily time range

代码如下：

// The "sunday" products (setting your product IDS in the array)
function sunday_products() {
    // HERE your product IDs in the array (need to be coma separated)
    return array( 37 );
}

// The 12h to 14h30 products (setting your product IDS in the array)
function time_range_products() {
    // HERE your product IDs in the array (need to be coma separated)
    return array( 53, 57 );
}

// Utility conditional function that check if day is sunday (returns boolean)
function is_sunday() {
    // Set Your shop time zone (http://php.net/manual/en/timezones.php)
    date_default_timezone_set('Europe/London');

    // If the current day is "sunday" return true (else retun false)
    return ( date('w') == 0 ) ? true : false;
}

// Utility conditional funtion for open hours (returns boolean true when store is open)
function in_time_range() {
    // Set Your shop time zone (http://php.net/manual/en/timezones.php)
    date_default_timezone_set('Europe/London');

    // Below your shop time and dates settings
    $open_time = mktime('12', '00', '00', date('m'), date('d'), date('Y')); // 12:00:00
    $end_time  = mktime('14', '30', '00', date('m'), date('d'), date('Y')); // 14:30:00
    $now       = time(); // Current timestamp in seconds

    return ( $now >= $start_time && $now <= $end_time ) ? true : false;
}


// Enable purchases for specific items on sundays only
add_filter( 'woocommerce_variation_is_purchasable', 'enable_specific_products_on_sundays', 10, 2 );
add_filter( 'woocommerce_is_purchasable', 'enable_specific_products_on_sundays', 10, 2 );
function enable_specific_products_on_sundays( $purchasable, $product ) {
    // Enable purchases for specific defined item only on sunday
    if( ! is_sunday() && in_array( $product->get_id(), sunday_products() ) )
        $purchasable = false;

    // Enable purchases for specific defined item only from 12h to 14h30
    if( ! in_time_range() && in_array( $product->get_id(), time_range_products() ) )
        $purchasable = false;

    return $purchasable;
}

// Add a notice in specific products outside sundays
add_action( 'woocommerce_before_single_product', 'filter_before_single_product' );
function filter_before_single_product() {
    global $product;

    // For sundays product
    if( ! is_sunday() && in_array( $product->get_id(), sunday_products() ) ) {
        wc_print_notice( __( 'This product is only purchasable on sundays', 'woocommerce' ), 'error' );
    } 
    // For hour range product
    elseif( ! in_time_range() && in_array( $product->get_id(), time_range_products() ) ) {
        wc_print_notice( __( 'This product is only purchasable between 12 AM and 2h30 PM', 'woocommerce' ), 'error' );
    }
}

// IN CASE OF (but not needed): Cart and checkout validation + error message
add_action( 'woocommerce_check_cart_items', 'conditionally_allowing_checkout' );
add_action( 'woocommerce_checkout_process', 'conditionally_allowing_checkout' );
function conditionally_allowing_checkout() {
    // Loop through cart items
    foreach( WC()->cart->get_cart() as $cart_item ){
        // Check cart items
        if( ! is_sunday() && in_array( $cart_item['data']->get_id(), sunday_products() ) ){
            wc_add_notice( sprintf(__("%s can be only purchase on sundays.", "woocommerce"), $cart_item['data']->get_name() ), 'error' );
            break;
        }
        else if( ! in_time_range() && in_array( $cart_item['data']->get_id(), time_range_products() ) ){
            wc_add_notice( sprintf(__("%s can be only purchase between 12 AM and 2h30 PM.", "woocommerce"), $cart_item['data']->get_name() ), 'error' );
            break;
        }
    }
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。它应该可以工作。
