添加一个 select 字段，其时间间隔基于 WooCommerce 结帐中的开始、结束和休息时间

Question

我正在使用 WooCommerce 构建披萨外卖网站。事实上，当顾客结账时，他可以select什么时候送餐。

select 框应包含从当前时间到清除所有过去时间的 15 分钟间隔。我想要的第一个选项是“尽快”，然后下一个选项是一个小时后（四舍五入到最接近的 15 分钟），然后每次都是 15 分钟。

我们的送货时间如下：

• 星期一：关闭
• 周二 - 周五 11:30 - 14:00 & 17:00 - 22:00
• 周六和周日：13:00 - 22:00

我成功地 WooCommerce action/hook，但我无法禁用当前时间之前的所有时间段。

add_action('woocommerce_before_order_notes', 'wps_add_select_checkout_field');
function wps_add_select_checkout_field( $checkout ) {
    woocommerce_form_field( 'lieferzeit', array(
        'type'          => 'select',
        'class'         => array( 'wps-drop' ),
        'label'         => __( '<div class="gew"><span class="gew-lz">Gewünschte Lieferzeit</span></div>'),
         'options'       => array(
            'asap'      => __( 'So schnell wie möglich', 'wps' ),
            '12:00'                     => __( '12:00', 'wps' ),
            '12:30'                     => __( '12:30', 'wps' ),

    ),

    $checkout->get_value( 'lieferzeit' ));

关于 select 字段的问题，您可以使用以下内容

通过 $store_times 数组，您可以设置开始和结束时间以及休息时间。

如果商店全天不营业，请将当天的所有设置留空（见星期一）

function action_woocommerce_before_order_notes( $checkout ) {       
    // Open, break and close time   
    $store_times = array(
        array( // Sunday (NO break)
            'open'    => '13:00',
            'break_s' => '',
            'break_e' => '',
            'close'   => '22:00',
        ), 
        array( // Monday (closed, so everything is empty)
            'open'    => '',
            'break_s' => '',
            'break_e' => '',
            'close'   => '',
        ), 
        array( // Tuesday
            'open'    => '11:30',
            'break_s' => '14:00',
            'break_e' => '17:00',
            'close'   => '22:00',
        ), 
        array( // Wednesday
            'open'    => '11:30',
            'break_s' => '14:00',
            'break_e' => '17:00',
            'close'   => '22:00',
        ), 
        array( // Thursday
            'open'    => '11:30',
            'break_s' => '14:00',
            'break_e' => '17:00',
            'close'   => '23:30',
        ), 
        array( // Friday
            'open'    => '11:30',
            'break_s' => '14:00',
            'break_e' => '17:00',
            'close'   => '22:00',
        ),
        array( // Saturday
            'open'    => '13:00',
            'break_s' => '',
            'break_e' => '',
            'close'   => '22:00',
        ), 
    );
    
    // Current time
    $current_time = current_time( 'timestamp' );
    
    // Current day, 0 for Sunday, 6 for Saturday
    $current_day = date( 'w', $current_time );

    // Get values for the current day
    $open_time = strtotime( $store_times[ $current_day][ 'open' ] );
    $break_start = strtotime( $store_times[ $current_day][ 'break_s' ] );
    $break_end = strtotime( $store_times[ $current_day][ 'break_e' ] ); 
    $close_time = strtotime( $store_times[ $current_day][ 'close' ] );
    
    // Open time is empty or before/passed open/close time, so the store is closed
    if ( empty ( $open_time ) || ( $current_time > $close_time || $current_time <= $open_time ) ) {
        // Default value
        $options['closed'] = __( 'Closed', 'woocommerce');
    } else {
        // Default value
        $options[''] = __( 'As soon as possible', 'woocommerce');
        
        // As soon as possible
        $asa_possible = strtotime( '+1 hour', $current_time );
    
        // Round to next 15 minutes (15 * 60 seconds)
        $asa_possible = ceil( $asa_possible / ( 15 * 60 ) ) * ( 15 * 60);
        
        // Add a new option every 15 minutes
        while( $asa_possible <= $close_time && $asa_possible >= $open_time ) {
            // Generate value
            $value = date( 'H:i', $asa_possible );
            
            // NOT between break start & break end
            if ( $value <= date( 'H:i', $break_start ) || $value >= date( 'H:i', $break_end ) ) {
                // Push to array
                $options[$value] = $value;
            }
            
            // Add 15 minutes to the variable in this while loop
            $asa_possible = strtotime( '+15 minutes', $asa_possible );
        }
    }


    // Add field
    woocommerce_form_field( 'delivery_time', array(
        'type'          => 'select',
        'class'         => array( 'wps-drop' ),
        'label'         => __('Desired delivery time', 'woocommerce' ),
        'options'       => $options,
    ), $checkout->get_value( 'delivery_time' ) );
}
add_action( 'woocommerce_before_order_notes', 'action_woocommerce_before_order_notes', 10, 1 );
