基于时间与日期的WooCommerce加入购物车功能启禁实现问询

Got it, let's solve this exact scenario where you need to enable the add-to-cart button only between 17:00 and 02:00 (next day) from Monday to Sunday, and disable it entirely on Tuesdays. Here's the tailored code snippet you can use:

/**
 * WooCommerce: Enable/Disable Add-to-Cart Based on Day & Time
 */
add_filter( 'woocommerce_is_purchasable', 'bbloomer_restrict_add_to_cart_by_day_time', 10, 2 );
add_filter( 'woocommerce_variation_is_purchasable', 'bbloomer_restrict_add_to_cart_by_day_time', 10, 2 );

function bbloomer_restrict_add_to_cart_by_day_time( $purchasable, $product ) {
    // Get current time in WordPress site's timezone (avoids UTC mismatch)
    $current_time = current_time( 'timestamp' );
    $current_day = date( 'N', $current_time ); // 1 = Monday, 7 = Sunday
    $current_hour = date( 'H', $current_time );

    // Case 1: Tuesday (day 2) - disable add-to-cart entirely
    if ( $current_day == 2 ) {
        return false;
    }

    // Case 2: Check if current time falls within 17:00 to 02:00 next day
    $evening_start = strtotime( '17:00', $current_time );
    next_day_morning_end = strtotime( '+1 day 02:00', $current_time );

    // Handle cross-day time range (evening to midnight + midnight to next day 02:00)
    if ( ( $current_time >= $evening_start && $current_time <= strtotime( '23:59:59', $current_time ) ) || 
         ( $current_time >= strtotime( '00:00:00', $current_time ) && $current_time <= $next_day_morning_end ) ) {
        return $purchasable; // Keep add-to-cart enabled
    } else {
        return false; // Disable add-to-cart
    }
}

Key Details Explained: #

• Timezone Accuracy: Uses current_time('timestamp') to respect your WordPress site's configured timezone, so you won't run into issues with UTC offsets messing up your schedule.
• Tuesday Lockout: date('N') returns 2 for Tuesday, so we immediately disable the add-to-cart button for the entire day.
• Cross-Day Handling: The code splits the 17:00-02:00 window into two logical parts (evening to midnight, and midnight to early morning) to ensure the restriction works correctly across the day boundary.
• Full Product Support: Targets both simple products (woocommerce_is_purchasable) and variable products (woocommerce_variation_is_purchasable) to maintain consistency across your store.

How to Implement: #

• Add this code to your child theme's functions.php file (always use a child theme to avoid losing changes when your parent theme updates).
• If you're not comfortable editing theme files, use a code snippet plugin (like Code Snippets) to safely add the code without touching core theme files.
• Double-check your WordPress timezone settings (under Settings > General) to ensure the time checks align with your local business hours.
