Php 在Woocommerce 3中的新订单电子邮件的干净表格中添加一些元数据值

在函数文件中，我创建了代码。任务：将订单数据添加到电子邮件警报。 网站上没有注册。 我想把它做为一张有标题的桌子。我发现了一个类似的例子。但其中所有的数据都来自模块的元数据。我将元数据和默认信息放在一起。 不需要编写所有的html。只要把我推向正确的方向，我的数据写得多么正确

add_filter( 'woocommerce_email_order_meta_fields', 'custom_woocommerce_email_order_meta_fields', 10, 3 );
function custom_woocommerce_email_order_meta_fields( $fields, $sent_to_admin, $order ) {
    $fields['billing_first_name'] = array(
        'label' => __( 'Name' ),
        'value' => $order->get_billing_first_name(),
    );

    $fields['billing_phone'] = array(
        'label' => __( 'Phone' ),
        'value' => $order->get_billing_phone(),
    );

    $fields['billing_address_1'] = array(
        'label' => __( 'Street' ),
        'value' => $order->get_billing_address_1(),
    );

    $fields['billing_address_2'] = array(
        'label' => __( 'Build' ),
        'value' => $order->get_billing_address_2(),
    );

    $fields['billing_address_3'] = array(
        'label' => __( 'Apartment' ),
        'value' => get_post_meta( $order->id, 'Apartment', true ),
    );

    $fields['billing_address_4'] = array(
        'label' => __( 'Floor' ),
        'value' => get_post_meta( $order->id, 'Floor', true ),
    );

    $fields['billing_address_5'] = array(
        'label' => __( 'Entrance' ),
        'value' => get_post_meta( $order->id, 'Entrance', true ),
    );

    $fields['customer_message'] = array(
        'label' => __( 'Note' ),
        'value' => $order->customer_message,
    );

    return $fields;
}

注意：在您的代码中将过时的

$order->id

替换为

$order->get_id（）

要在干净的html中添加具有默认顺序元数据的自定义字段元数据，请尝试以下操作：

add_action('woocommerce_email_order_details', 'action_after_email_order_details', 25, 4 );
function action_after_email_order_details( $order, $sent_to_admin, $plain_text, $email )
{
    $domain = 'woocommerce';

    // Define all translatable custom fields labels and data
    $fields_array = [
        [ 'label' => __( 'Name', $domain ),      'value' => $order->get_billing_first_name() ],
        [ 'label' => __( 'Phone', $domain ),     'value' => $order->get_billing_phone() ],
        [ 'label' => __( 'Street', $domain ),    'value' => $order->get_billing_address_1() ],
        [ 'label' => __( 'Build', $domain ),     'value' => $order->get_billing_address_2() ],
        [ 'label' => __( 'Apartment', $domain ), 'value' => $order->get_meta( 'Apartment', true ) ],
        [ 'label' => __( 'Floor', $domain ),     'value' => $order->get_meta( 'Floor', true ) ],
        [ 'label' => __( 'Entrance', $domain ),  'value' => $order->get_meta( 'Entrance', true ) ],
        [ 'label' => __( 'Note', $domain ),      'value' => $order->get_customer_note() ],
    ];

    // The HTML Structure
    $html_output = '<h2>' . __( 'Extra data (title)', $domain ) . '</h2>
    <div class="discount-info">
        <table cellspacing="0" cellpadding="6"><tbody>';

    // Loop though the data array to set the fields
    foreach( $fields_array as $field ):

    // Only display non empty fields values
    if( ! empty($field['value']) ):

    $html_output .= '<tr>
        <th>' . $field['label'] . ':</th>
        <td>' . $field['value'] . '</td>
    </tr>';

    endif;
    endforeach;

    $html_output .= '</tbody></table>
    </div><br>'; // HTML (end)

    // The CSS styling
    $styles = '<style>
        .discount-info table{width: 100%; font-family: \'Helvetica Neue\', Helvetica, Roboto, Arial, sans-serif;
            color: #737373; border: 1px solid #e4e4e4; margin-bottom:8px;}
        .discount-info table th, table.tracking-info td{text-align: left; border-top-width: 4px;
            color: #737373; border: 1px solid #e4e4e4; padding: 12px;}
        .discount-info table td{text-align: left; border-top-width: 4px; color: #737373; border: 1px solid #e4e4e4; padding: 12px;}
    </style>';

    // The Output CSS + HTML
    echo $styles . $html_output;
}

非常感谢！你是最棒的！

if ( $email->id !== 'new_order' ) return;
