在WooCommerce的管理订单编辑页面上获取嵌套自定义字段元数据

2022-09-03 00:00:00 php wordpress woocommerce checkout orders

在WooCommerce中,我已根据购物车数量在结账页面上添加了自定义字段。

// 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( "
", $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('
', '', $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]));


  }}}

所有工作正常,并且验证并保存了字段。

问题:我无法获取和显示管理订单编辑页面中的值。

因为我现在不知道根据订购金额创建了多少个域,所以我首先需要获取订购物品的数量。

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和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?

如有任何帮助,将不胜感激。


解决方案

您使事情变得有点复杂,并且您的代码中存在一些错误。

最好将与会者的预订数据显示为管理商店订单编辑页面中的自定义元框(在右栏中)。

所以我完全重新查看了您的代码:

// 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( "
", $einstiegsorte );
            if( sizeof( $option_items ) > 1 ){
                foreach( $option_items as $value )
                    $options[$value] = $value;
            } else {
                $value = str_replace('
', '', $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(
                    'type'          => 'text',
                     'class'         => array('checkout_vorname'),
                    'label'         => __('Vorame'),
                    'required'      => true,
            ), $checkout->get_value( '_teilnehmer_vorame_'.$j ));

            woocommerce_form_field( '_teilnehmer_nachname_'.$j, array(
                    'type'          => 'text',
                    'class'         => array('checkout_nachname'),
                    'label'         => __('Nachname'),
                    'required'      => true,
            ), $checkout->get_value( '_teilnehmer_nachname_'.$j ));

            woocommerce_form_field( '_teilnehmer_einstiegswahl_'.$j, array(
                'type'          => 'select',
                'class'         => array('checkout_einstiegswahl'),
                'label'         => __('Einstiegswahl'),
                'required'      => true,
                'options'       => $options,
            ), $checkout->get_value( '_teilnehmer_einstiegswahl_'.$j ));
        }
        $count++;
    }
}

// Custom checkout fields validation
add_action('woocommerce_checkout_process', 'srd_teilnehmer_fields_process');
function srd_teilnehmer_fields_process() {
    $count = 1;

    // Loop through cart items
    foreach( WC()->cart->get_cart() as $cart_item ) {

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

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

            if (!$_POST['_teilnehmer_vorame_'.$j] || !$_POST['_teilnehmer_nachname_'.$j] || !$_POST['_teilnehmer_einstiegswahl_'.$j])
                wc_add_notice( __( 'Bitte wählen Sie Ihren Einstiegsort', 'woocommerce' ), 'error' );
        }
        $count++;
    }
}

// Update the order meta data with checkout custom fields values
add_action('woocommerce_checkout_create_order', 'srd_teilnehmer_checkout_create_order', 20, 2 );

    $count = 1;

    // Loop through cart item quantity
    foreach( WC()->cart->get_cart() as $cart_item ) {

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

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

            if ( isset($_POST['_teilnehmer_vorame_'.$j]) )
                $order->update_meta_data( '_teilnehmer_vorame_'.$j , sanitize_text_field($_POST['_teilnehmer_vorame_'.$j]) );

            if ( isset($_POST['_teilnehmer_nachname_'.$j]) )
                $order->update_meta_data( '_teilnehmer_nachname_'.$j, sanitize_text_field($_POST['_teilnehmer_nachname_'.$j]) );

            if ( isset($_POST['_teilnehmer_einstiegswahl_'.$j]) )
                $order->update_meta_data( '_teilnehmer_einstiegswahl_'.$j, sanitize_text_field($_POST['_teilnehmer_einstiegswahl_'.$j]) );
        }
        $count++;
    }
}

// Adding Custom metabox in admin orders edit pages (on the right column)
add_action( 'add_meta_boxes', 'add_reiseteilnehmer_metabox' );
function add_reiseteilnehmer_metabox(){
    add_meta_box(
        'attendees',
        __('Reiseteilnehmer'),
        'reiseteilnehmer_inhalt',
        'shop_order',
        'side', // or 'normal'
        'default' // or 'high'
    );
}

// Adding the content for the custom metabox
function reiseteilnehmer_inhalt() {
    $order = wc_get_order(get_the_id());

    $count = 1;

    $key_labels = array( 'vorame', 'nachname', 'einstiegswahl' );

    // Loop through order items
    foreach ( $order->get_items() as $item ){

        echo '<h4 style="margin:1em 0 .5em;">Order item '.$count.'</h4>';

            echo '</tbody></table></div>';
        }
        $count++;
    }
}

代码放在活动子主题(或活动主题)的函数.php文件中。已测试并正常工作。

要在电子邮件和前端的"已收到订单"和"我的帐户"页面中显示该信息,您必须提出一个新问题,因为这个问题范围太广,无法用一个答案来回答。
