使用 date_i18n 格式化 WooCommerce 传递消息的日期

Question

使用 WooCommerce，我使用以下挂钩连接到存档、产品页面、购物车和结账：woocommerce_before_single_product_summarywoocommerce_before_shop_loopwoocommerce_before_cartwoocommerce_before_checkout_form然后我使用一个if参数，后跟一个elseif，最后是else。这些参数控制向客户/访客显示的传递消息。我的主要问题是格式化日期。电流输出：周一下午 6 点之前下的订单将在 8 月 18 日周二或最迟次日送达。预期输出：周一下午 6 点之前下的订单将在 8 月 18 日周二或最迟次日送达。换句话说，我想在该句子中添加“the”和“of”，使其更清晰、更易于阅读。附加的“the”和“of”适用于任何格式，例如按月份的第 1 日、第 2 日、第 5 日甚至第 23 日。我已阅读“格式化日期和时间”WordPress Codex 页面，但即使使用“\t\h\e”和“\o\f”格式，日期显示的格式也不正确。这是我到目前为止的代码。如果有人可以为我格式化日期或解释如何将其更改为我想要的输出，我将不胜感激。add_action( 'woocommerce_before_single_product_summary', 'product_delivery_message' );add_action( 'woocommerce_before_shop_loop', 'product_delivery_message' );add_action( 'woocommerce_before_cart', 'product_delivery_message' );add_action( 'woocommerce_before_checkout_form', 'product_delivery_message' );function product_delivery_message() {date_default_timezone_set( 'Europe/Paris' );    // delivery cut-off for friday and weekend    if ( date_i18n( 'N' ) >= 5 ) {        $delivery_day = date_i18n( "l, F jS, ", strtotime( "next wednesday" ));        $order_before = "Monday";    }    // on monday to thursday before XX (currently set to 18 = 6PM), delivery will be on next week tuesday    elseif ( date_i18n( 'H' ) >= 18 ) {        $delivery_day = date_i18n( "l, F jS, ", strtotime( "day after tomorrow" ));        $order_before = "tomorrow";    }    // monday to thursday within the cut-off time, delivery will be next day (tomorrow)    else {        $delivery_day = date_i18n( "l, F jS, ", strtotime( "tomorrow" ));        $order_before = "today";    }    $delivery_message = "<div class='product-delivery-message' style='clear:both'>Orders made before 6PM {$order_before} will be delivered on {$delivery_day} or the day after at the latest.</div>";        echo $delivery_message;}

使用l, \t\h\e jS \of F,格式化字符串，我可以使用您的代码获得正确的输出。我还做了一些更改，例如替换"day after tomorrow"为"+2 days"和使用的sprintf()功能：

add_action( 'woocommerce_before_single_product_summary', 'product_delivery_message' );

add_action( 'woocommerce_before_shop_loop', 'product_delivery_message' );

add_action( 'woocommerce_before_cart', 'product_delivery_message' );

add_action( 'woocommerce_before_checkout_form', 'product_delivery_message' );

function product_delivery_message() {

    date_default_timezone_set( 'Europe/Paris' );

    $date_format = __('l, \t\h\e jS \of F,', 'woocommerce');

    // 1. Delivery cut-off for friday and weekend

    if ( date_i18n('N') >= 5 ) {

        $delivery_day = date_i18n( $date_format, strtotime( "next wednesday" ) );

        $order_before = __('Monday', 'woocommerce');

    }

    // 2. From monday to thursday before XX (currently set to 18 = 6PM), delivery will be on next week tuesday

    elseif ( date_i18n('H') >= 18 ) {

        $delivery_day = date_i18n( $date_format, strtotime( "+2 days" ) );

        $order_before = __('tomorrow', 'woocommerce');

    }

    // 3. From monday to thursday within the cut-off time, delivery will be next day (tomorrow)

    else {

        $delivery_day = date_i18n( $date_format, strtotime( "+1 day" ) );

        $order_before = __('today', 'woocommerce');

    }

    $message = sprintf( 

        __("Orders made before 6PM %s will be delivered on %s or the day after at the latest.", "woocommerce"),

        $order_before, $delivery_day 

    );

    echo '<div class="product-delivery-message" style="clear:both">' . $message . '</div>';

}

代码位于活动子主题（或活动主题）的functions.php 文件中。经过测试并有效。
