如何配置Woocommerce Bookings资源分组：预订7人制场地锁定2个5人制场地

Great question! WooCommerce Bookings doesn't have a built-in visual setting to link resource availability like this, but we can achieve exactly what you need with a bit of custom code. Let's break this down step by step:

1. Grab Your Resource IDs First #

First, you'll need the unique IDs for your three venues:

• Go to Products > Edit your "Futsal" booking product > Resources tab
• Hover over each resource name (7-a-side, 5-a-side 1, 5-a-side 2) — your browser's status bar will show a URL with post=XXX; that number is the resource ID. Jot them down:
  • 7-a-side venue ID (e.g., 100)
  • 5-a-side venue 1 ID (e.g., 101)
  • 5-a-side venue 2 ID (e.g., 102)

2. Add Custom Code to Your Site #

You can add this code to your child theme's functions.php file, or use the Code Snippets plugin (safer, since it won't get overwritten when you update your theme):

// Lock 5-a-side venues when 7-a-side is booked
function lock_five_a_side_when_seven_booked( $availability, $resource_id, $args ) {
    // Replace these IDs with your actual resource IDs
    $seven_a_side_id = 100;
    $five_a_side_ids = array(101, 102);

    // Check if we're checking availability for a 5-a-side venue
    if ( in_array( $resource_id, $five_a_side_ids ) ) {
        // Get the requested booking time window
        $start_date = $args['start'];
        $end_date = $args['end'];

        // Look for existing confirmed/paid/pending bookings for the 7-a-side venue in this window
        $existing_bookings = get_posts( array(
            'post_type'      => 'wc_booking',
            'post_status'    => array( 'paid', 'confirmed', 'pending' ),
            'meta_query'     => array(
                array(
                    'key'     => '_booking_resource_id',
                    'value'   => $seven_a_side_id,
                    'compare' => '=',
                ),
                array(
                    'key'     => '_booking_start',
                    'value'   => $end_date->getTimestamp(),
                    'compare' => '<',
                ),
                array(
                    'key'     => '_booking_end',
                    'value'   => $start_date->getTimestamp(),
                    'compare' => '>',
                ),
            ),
        ) );

        // If there's an active 7-a-side booking, mark the 5-a-side venue as unavailable
        if ( ! empty( $existing_bookings ) ) {
            $availability['available'] = false;
            $availability['message'] = __( 'This 5-a-side venue is unavailable because the 7-a-side venue has been booked for this time slot.', 'woocommerce-bookings' );
        }
    }

    return $availability;
}
add_filter( 'woocommerce_booking_get_availability', 'lock_five_a_side_when_seven_booked', 10, 3 );

3. How This Code Works #

• We use the woocommerce_booking_get_availability filter to intercept availability checks for your 5-a-side venues.
• For each check, we look for any active bookings (paid, confirmed, or pending) for the 7-a-side venue in the same time window.
• If a conflicting booking exists, we mark the 5-a-side venue as unavailable and show a clear message to users.

4. Optional: Reverse Lock (Lock 7-a-Side When 5-a-Side is Booked) #

If you also want to prevent booking the 7-a-side venue when either 5-a-side venue is booked, add this additional code:

// Lock 7-a-side venue when any 5-a-side venue is booked (optional)
function lock_seven_a_side_when_five_booked( $availability, $resource_id, $args ) {
    $seven_a_side_id = 100;
    $five_a_side_ids = array(101, 102);

    if ( $resource_id == $seven_a_side_id ) {
        $start_date = $args['start'];
        $end_date = $args['end'];

        $existing_bookings = get_posts( array(
            'post_type'      => 'wc_booking',
            'post_status'    => array( 'paid', 'confirmed', 'pending' ),
            'meta_query'     => array(
                array(
                    'key'     => '_booking_resource_id',
                    'value'   => $five_a_side_ids,
                    'compare' => 'IN',
                ),
                array(
                    'key'     => '_booking_start',
                    'value'   => $end_date->getTimestamp(),
                    'compare' => '<',
                ),
                array(
                    'key'     => '_booking_end',
                    'value'   => $start_date->getTimestamp(),
                    'compare' => '>',
                ),
            ),
        ) );

        if ( ! empty( $existing_bookings ) ) {
            $availability['available'] = false;
            $availability['message'] = __( 'The 7-a-side venue is unavailable because a 5-a-side venue has been booked for this time slot.', 'woocommerce-bookings' );
        }
    }

    return $availability;
}
add_filter( 'woocommerce_booking_get_availability', 'lock_seven_a_side_when_five_booked', 10, 3 );

5. Test Thoroughly #

After adding the code, make sure to test the flow:

1. Book the 7-a-side venue for a specific time slot.
2. Try booking either 5-a-side venue for the same slot — it should show as unavailable with your custom message.
3. Cancel the 7-a-side booking, and the 5-a-side venues should become available again.
