对于预订网站,我已激活“时区”.应显示访客的当地时间.在预订表格中,一切正常.使用以下功能时,购物车数据($start_time,$end_time)显示不正确.

add_filter( 'woocommerce_get_item_data', 'display_cart_data_wc_bookings', 10, 2 );
function display_cart_data_wc_bookings( $item_data, $cart_item ){

    if ( ! empty( $cart_item['booking'] ) ) {

        $date_format = apply_filters( 'woocommerce_bookings_date_format', wc_date_format() );
        $time_format = apply_filters( 'woocommerce_bookings_time_format', wc_time_format() );
        $start_date = apply_filters( 'woocommerce_bookings_get_start_date_with_time', date_i18n(  $date_format, $cart_item['booking']['_start_date'] ) );
        $start_time = apply_filters( 'woocommerce_bookings_get_start_date_with_time', date_i18n(  $time_format, $cart_item['booking']['_start_date'] ) );
        $end_time = apply_filters( 'woocommerce_bookings_get_end_date_with_time', date_i18n(  $time_format, $cart_item['booking']['_end_date'] ) );
        $persons = $cart_item['booking']['_persons'];
        $ID = $cart_item['booking']['_booking_id'];

        echo '<dt class="titel datum">' . __('Date', 'woocommerce') . '</dt><dd class="data datum">' . esc_html( $start_date ) . '</dd>';
        echo '<dt class="titel tijdvak">' . __('Time', 'woocommerce') . '</dt><dd class="data tijdvak">' . esc_html( $start_time ) . ' - ' . esc_html( $end_time ) . '</dd>';
        foreach($persons as $person){
            echo '<dt class="titel personen">' . __('Persons', 'woocommerce') . '</dt><dd class="data personen">' . esc_html( $person) . '</dd>';
        }
        echo '<dt class="titel booking_id">' . __('Booking #', 'woocommerce') . '</dt><dd class="data booking_id">' . esc_html( $ID) . '</dd>';

    }
}

$start_time和$end_time的输出应显示在访问者的本地时间.我该如何实现？

解决方法:

要启用用户时区,必须使用jQuery和ajax.以下是以下步骤：

>尽早启用用户WooCommerce会话(WC Session),
>获取用户浏览器时区(用户计算机或设备的时区),
>通过Ajax将时区发送到php,
>在用户WC会话中获取该时区,
>然后在日期和时间的php函数代码中将其用作date(),date_i18n(),time()…

将用户时区保存在WC Session中后,所有相关代码将被自动禁用(不再需要).

编码：

// Early enable customer WC_Session (if not done)
add_action( 'init', 'wc_session_enabler' );
function wc_session_enabler() {
    if ( ! WC()->session->has_session() ) {
        WC()->session->set_customer_session_cookie( true );
    }
}

// Get the browser user timezone and send it to php (Ajax)
add_action( 'wp_head', 'user_timmezone_js' );
function user_timmezone_js() {
    if( ! WC()->session->get('time-zone') ) :
    ?>
    <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jstimezonedetect/1.0.6/jstz.min.js"></script>
    <script type="text/javascript">
    jQuery( function($){
        if (typeof woocommerce_params === 'undefined') 
            return false;

        var tz = jstz.determine();

        $.ajax({
            type: "POST",
            url: woocommerce_params.ajax_url,
            data: ({
                'action': 'time_zone',
                'timezone': tz.name()
            }),
            success: function(response) {
                console.log('Success: '+response);
            }
        });
    });
    </script>
    <?php
    endif;
}

// function that gets the Ajax data and save it to user WC Session
add_action( 'wp_ajax_time_zone', 'set_session_timezone' );
add_action( 'wp_ajax_nopriv_time_zone', 'set_session_timezone' );
function set_session_timezone() {
    if ( isset($_POST['timezone']) && ! empty($_POST['timezone']) ){
        WC()->session->set('time-zone', esc_attr($_POST['timezone']) );
        echo  WC()->session->get('time-zone');
    }
    die();
}

代码进入您的活动子主题(或活动主题)的function.php文件中.

Then you will include the following to get and set the time zone:

06001

更新：

现在,使用woocommerce_get_item_data时,您的代码不正确,因为它是过滤器挂钩,需要返回过滤后的内容(而不是回显html)…

请尝试以下操作(未经测试)：

add_filter( 'woocommerce_get_item_data', 'display_cart_data_wc_bookings', 10, 2 );
function display_cart_data_wc_bookings( $item_data, $cart_item ){
    if ( isset($cart_item['booking']) && ! empty($cart_item['booking']) && ! is_admin() ) {
        // Get and set the user time zone
        if( $timezone = WC()->session->get('time-zone') ) {
            date_default_timezone_set($timezone);
        }
        $booking_data = $cart_item['booking'];
        $date_format  = apply_filters( 'woocommerce_bookings_date_format', wc_date_format() );
        $time_format  = apply_filters( 'woocommerce_bookings_time_format', wc_time_format() );
        $start_date   = apply_filters( 'woocommerce_bookings_get_start_date_with_time', date_i18n(  $date_format, $booking_data['_start_date'] ) );
        $start_time   = apply_filters( 'woocommerce_bookings_get_start_date_with_time', date_i18n(  $time_format, $booking_data['_start_date'] ) );
        $end_time     = apply_filters( 'woocommerce_bookings_get_end_date_with_time', date_i18n(  $time_format, $booking_data['_end_date'] ) );
        $persons      = $booking_data['_persons'];
        $booking_id   = $booking_data['_booking_id'];

        $item_data[] = array(
            'key'       => __('Date', 'woocommerce'),
            'value'     => esc_html( $start_date ),
            'display'   => esc_html( $start_date ),
        );

        $item_data[] = array(
            'key'       => __('Time', 'woocommerce'),
            'value'     => esc_html( $start_time ),
            'display'   => esc_html( $start_time ),
        );

        $count = 1;

        foreach($persons as $person){
            $item_data[] = array(
                'key'       => __('Person', 'woocommerce') . $count,
                'value'     => esc_html( $person ),
                'display'   => esc_html( $person ),
            );
            $count++;
        }

        $item_data[] = array(
            'key'       => __('Booking #', 'woocommerce'),
            'value'     => esc_html( $booking_id ),
            'display'   => esc_html( $booking_id ),
        );
    }
    return $item_data;
}
