在后端显示Woocommerce中下拉签出字段中的选项标签

Question

我在woocommerce的结账处创建了一个下拉字段，并给每个人一个命名的密钥。我的问题是如何保存命名的密钥并在后端显示它们。到现在为止我还不能出示那把钥匙。

function cloudways_custom_checkout_fields($fields){
$fields['cloudways_extra_fields'] = array(

        'cloudways_dropdown' => array(
            'type' => 'select',
            'options' => array( 'freudige_anlaesse' => __( 'Freudige Anlässe' ), 'traurige_anlaesse' => __( 'Traurige Anlässe' ), 'testamentsspende' => __( 'Testamentsspende' ), 'stiftungen' => __( 'Stiftungen' ), 'unternehmen' => __( 'Unternehmen' ) ),
            'required'      => true,
            'label' => __( 'Grund Ihrer Spende' )
            )
        );

return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'cloudways_custom_checkout_fields' );

function cloudways_extra_checkout_fields(){

$checkout = WC()->checkout(); ?>

<div class="col-2">
<h3><?php _e( 'Verwendungszweck' ); ?></h3>

<?php
   foreach ( $checkout->checkout_fields['cloudways_extra_fields'] as $key => $field ) : ?>

        <?php woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); ?>

    <?php endforeach; ?>
</div>

<?php }
    add_action('woocommerce_checkout_after_customer_details','cloudways_extra_checkout_fields'  );

这是我保存的数据。

//SAVE THE DATA
function cloudways_save_extra_checkout_fields( $order_id, $posted ){
// don't forget appropriate sanitization if you are using a different field type
if( isset( $posted['cloudways_text_field'] ) ) {
    update_post_meta( $order_id, '_cloudways_text_field', sanitize_text_field( $posted['cloudways_text_field'] ) );
}

if( isset( $posted['cloudways_dropdown'] ) && in_array( $posted['cloudways_dropdown'], array( 'freudige_anlaesse' , 'traurige_anlaesse', 'testamentsspende', 'stiftungen', 'unternehmen' ) ) ) {

    update_post_meta( $order_id, '_cloudways_dropdown', $posted['cloudways_dropdown'] );
}
}
add_action( 'woocommerce_checkout_update_order_meta', 'cloudways_save_extra_checkout_fields', 10, 2 );

在这里，我尝试在面板中显示数组。我要显示数组的fisrt部分，而不是与此值相关联的命名键。我怎样才能出示命名的钥匙？

function kia_display_order_data_in_admin( $order ){  ?>
<div class="order_data_column">
    <h4><?php _e( 'Verwendungszweck' ); ?></h4>
    <?php 
         echo '<p><strong>' . __( 'Grund der Spende: ' ) . '</strong>'. get_post_meta( $order->id, '_cloudways_dropdown', true ) . '</p>';?>

</div>

Update 2 -我重新访问了您的代码，做了一些更改，删除了不必要的代码，并使自定义字段值显示在管理订单编辑页面中：

function spende_options_array(){
    return array( 'freudige_anlaesse' => __( 'Freudige Anlässe' ), 'traurige_anlaesse' => __( 'Traurige Anlässe' ), 'testamentsspende' => __( 'Testamentsspende' ), 'stiftungen' => __( 'Stiftungen' ), 'unternehmen' => __( 'Unternehmen' ) );
}

add_filter( 'woocommerce_checkout_fields', 'add_custom_checkout_field' );
function add_custom_checkout_field($fields){
    $fields['extra_fields'] = array( 'spende_dropdown' => array(
        'type'     => 'select',
        'label'    => __( 'Grund Ihrer Spende' ),
        'options'  => spende_options_array(),
        'required' => true,
    ) );

    return $fields;
}

add_action('woocommerce_checkout_after_customer_details','add_extra_checkout_field'  );
function add_extra_checkout_field(){
    $checkout = WC()->checkout();
    ?>
    <div class="col-2">
    <h3><?php _e( 'Verwendungszweck' ); ?></h3>
    <?php

    foreach ( $checkout->checkout_fields['extra_fields'] as $key => $field ) :
        woocommerce_form_field( $key, $field, $checkout->get_value( $key ) );
    endforeach;
    ?>
    </div>
    <?php
}

add_action( 'woocommerce_checkout_create_order', 'save_extra_checkout_fields', 10, 2 );
function save_extra_checkout_fields( $order, $posted ){
    if( isset( $posted['spende_dropdown'] ) && in_array( $posted['spende_dropdown'], array( 'freudige_anlaesse' , 'traurige_anlaesse', 'testamentsspende', 'stiftungen', 'unternehmen' ) ) ) {
        $order->update_meta_data( '_spende_dropdown', $posted['spende_dropdown'] );
    }
}

add_action( 'woocommerce_admin_order_data_after_order_details', 'display_order_custom_meta_data_in_admin' );
function display_order_custom_meta_data_in_admin( $order ){
    $spende_options = spende_options_array();
    $key = get_post_meta( $order->get_id(), '_spende_dropdown', true );
    ?>
    <div class="order_data_column">
        <h4><?php _e( 'Verwendungszweck' ); ?></h4>
        <p><strong><?php _e( 'Grund der Spende: ' ); ?></strong><?php echo $spende_options[$key]; ?></p>
    </div>
    <?php
}

代码在您的活动子主题(或活动主题)的function.php文件中。测试和工作。

这将显示从下拉列表中选择的<option> 标签，并按管理编辑页面的顺序排列。
