Question

在woocommerce中，我根据购物车数量在结帐页面添加了自定义字段。

// Adding Custom Fields based on Cart Count

add_action( 'woocommerce_before_checkout_billing_form', 'srd_custom_einstiegswahl');

function srd_custom_einstiegswahl($checkout){

global $woocommerce;
$items = $woocommerce->cart->get_cart();

$i = 1;

foreach($items as $item => $values) { 
    $_product = $values['data']->post;
    $quantity = $values['quantity'];
    $x = 1;

    while ($x <= $quantity) {
            // Add fields here
            echo '<h6>Reiseteilnehmer '.$x . '</h6>';
            woocommerce_form_field( 'attendee_surname_'.$x, array(
                    'type'          => 'text',
                     'class'         => array('checkout_vorname'),
                    'label'         => __('Vorame'),
                    'placeholder'   => __(''),
                    'required'      => true
              ), $checkout->get_value( 'attendee_surname_'.$x ));
            woocommerce_form_field( 'attendee_name_'.$x, array(
                    'type'          => 'text',
                    'class'         => array('checkout_nachname'),
                    'label'         => __('Nachname'),
                    'placeholder'       => __(''),
                    'required'      => true
              ), $checkout->get_value( 'attendee_name_'.$x ));
            echo '<select name=einstiegswahl'.$x .'>';
            // Select field populated by Custom Product Meta
            echo '<option value="" style="display:none"> Bitte wählen Sie Ihren Einstiegsort </option>';

            // Loop through cart items
             foreach ( WC()->cart->get_cart() as $cart_item ) {
            // Get the custom field data
             $einstiegsorte = get_post_meta( $cart_item[ 'product_id' ], '_einstiegsorte', true );
            if( ! empty($einstiegsorte) ){
            // if it's multiline we split it in an array
            $select_field_items = explode( "\n", $einstiegsorte );
            // If the array has more than one item
                if( sizeof( $select_field_items ) > 1 ){
                     foreach( $select_field_items as $value )
                         echo '<option value="'. $value .'">' . $value . '</option>';
                } 
            // If there is only one line
                else {
                // we clean it
                $value = str_replace('\n', '', $einstiegsorte);
                echo '<option value="'. $value .'">' . $value . '</option>';
                    }
                }
            }

            echo '</select>'; $checkout->get_value( 'einstiegswahl'.$x );
        $x++;
    }

    $i++;
}   
}


// Process the checkout

add_action('woocommerce_checkout_process', 'srd_teilnehmer_fields_process');

function srd_teilnehmer_fields_process() {
global $woocommerce;
$items = $woocommerce->cart->get_cart();

$i = 1;

foreach($items as $item => $values) { 
    $_product = $values['data']->post;
    $quantity = $values['quantity'];
    $x = 1;

    for($x = 1; $x <= $quantity; $x++ ) {
    //while ($x <= $quantity) {
            if (!$_POST['attendee_surname_'.$x] || !$_POST['attendee_name_'.$x] || !$_POST['einstiegswahl'.$x]) wc_add_notice( __( 'Bitte wählen Sie Ihren Einstiegsort', 'woocommerce' ), 'error' );

        }
    }
}

// Update the order meta with field value

add_action('woocommerce_checkout_update_order_meta', 'srd_teilnehmer_update_order_meta');

function srd_teilnehmer_update_order_meta( $order_id ) {

global $woocommerce;
$items = $woocommerce->cart->get_cart();

$i = 1;

foreach($items as $item => $values) { 
    $_product = $values['data']->post;
    $quantity = $values['quantity'];
    $x = 1;

    for($x = 1; $x <= $quantity; $x++ ) {
            if ( $_POST['attendee_name_'.$x] ) update_post_meta( $order_id, 'attendee_surname_'.$x , sanitize_text_field($_POST['attendee_name_'.$x]) );
            if ($_POST['attendee_surname_'.$x]) update_post_meta( $order_id, 'attendee_name_'.$x, esc_attr($_POST['attendee_surname_'.$x]));
            if ($_POST['einstiegswahl'.$x]) update_post_meta( $order_id, ' Teilnehmer Einstiegsort' .$x, esc_attr($_POST['einstiegswahl'.$x]));


  }}}

一切正常，字段得到验证和保存。

问题：我无法在管理订单编辑页面中显示和显示值。

由于此时我不知道根据订购金额创建了多少字段，我首先需要获取一些订购商品。

以下是相关代码：

add_action( 'woocommerce_admin_order_data_after_billing_address', 'srd_teilnehmer_checkout_field_display_admin_order_meta', 10, 1 );
//add_action( 'woocommerce_email_order_meta', 'srd_teilnehmer_checkout_field_display_admin_order_meta', 10, 3 );

function srd_teilnehmer_checkout_field_display_admin_order_meta($order) {  

$order = wc_get_order( $order_id );

$items = $item_data->get_quantity();

  foreach($items as $item => $values) { 
    $order_quantity = $values['quantity'];
    $x = 1;

    while ($x <= $order_quantity) { 
        echo '<p><strong>'.__('Nachname'.$x).':</strong> ' . get_post_meta( $order->id, 'attendee_name_'.$x, true ) . '</p>';
}
}}

如何在管理订单编辑页面中获取并显示这些自定义字段值？
如何在电子邮件通知中显示自定义字段值？

任何帮助将不胜感激。

你使一些事情变得复杂，你的代码中也有一些错误。

在管理员工作室订单编辑页面（在右栏中显示）中将与会者预订数据显示为自定义元框应该更好。

所以我完全重新审视了你的代码：

// Adding Custom Fields based on Cart Count
add_action( 'woocommerce_before_checkout_billing_form', 'srd_custom_einstiegswahl');
function srd_custom_einstiegswahl( $checkout ){

    $count = 1;

    // Loop through cart items
    foreach( WC()->cart->get_cart() as $cart_item ) {
        $options       = array( '' => __("Bitte wählen Sie Ihren Einstiegsort") ); 
        $einstiegsorte = get_post_meta( $cart_item[ 'product_id' ], '_einstiegsorte', true );

        if( ! empty($einstiegsorte) ){
            $option_items = explode( "\n", $einstiegsorte );
            if( sizeof( $option_items ) > 1 ){
                foreach( $option_items as $value )
                    $options[$value] = $value;
            } else {
                $value = str_replace('\n', '', $einstiegsorte);
                $options[$value] = $value;
            }
        }

        // Loop through cart item quantity
        for($i = 1; $i <= $cart_item['quantity']; $i++ ) {

            $j = $count.'_'.$i;

            echo '<h6>Reiseteilnehmer '.$i . '</h6>';

            woocommerce_form_field( '_teilnehmer_vorame_'.$j, array(

代码放在活动子主题（或活动主题）的function.php文件中。经过测试和工作。

要在电子邮件和前端“已收到订单”和我的帐户“订单查看”页面中显示该问题，您将不得不提出一个新问题，因为它太宽泛而无法在一个答案中回答。
