如何在管理面板的WooCommerce订单中显示自定义选项字段？

实际上，这个问题已经回答了，因为我已经检查过了，但我无法对这个问题发表评论，因为我使用的是相同的代码，但在我的场景中，我使用的是选项字段，并且值没有反映在管理面板中，下面是我尝试的代码

    //*Multiple Options Php - Select Occasion*/

add_filter( \'woocommerce_checkout_fields\' , \'my_custom_checkout_field_update_order_meta\' );

function my_custom_checkout_field_update_order_meta( $fields ) { 
     $fields[\'billing\'][\'myfield\'] = array(
        \'type\'      => \'select\',
        \'id\' => \'myfield\',
        \'placeholder\'     => __(\'Select Occasion\', \'woocommerce\'),
        \'required\'  => false,
        \'class\'     => array(\'form-row-wide\'),
        \'clear\'     => false,
        \'options\'       => [
            \'key1\'  => __(\'Birthday\', \'woocommerce\'),
            \'key2\'  => __(\'Anniversary\', \'woocommerce\'),
            \'key3\'  => __(\'Congratulations\', \'woocommerce\'),
            \'key4\'  => __(\'Sorry\', \'woocommerce\'),
            \'key5\'  => __(\'Good Luck\', \'woocommerce\'),
            \'key6\'  => __(\'Thank You\', \'woocommerce\'),
            \'key7\'  => __(\'Get Well Soon\', \'woocommerce\'),
            \'key8\'  => __(\'Love\', \'woocommerce\'),
        ]
    );
    return $fields;
}

add_action( \'woocommerce_admin_order_data_after_billing_address\', \'edit_woocommerce_checkout_page\', 10, 1 );

function edit_woocommerce_checkout_page($order){
    global $post_id;
    $order = new WC_Order( $post_id );
    echo \'<p><strong>\'.__(\'Occasion\').\':</strong> \' . get_post_meta($order->get_id(), \'_myfield\', true ) . \'</p>\';
}

add_filter( \'woocommerce_checkout_fields\' , \'occasion_checkout_field_update_order_meta\' ); function occasion_checkout_field_update_order_meta( $fields ) { $fields[\'billing\'][\'occasion\'] = array( \'type\' => \'select\', \'id\' => \'occasion\', \'placeholder\' => __(\'Select Occasion\', \'woocommerce\'), \'required\' => false, \'class\' => array(\'form-row-wide\'), \'clear\' => false, \'options\' => array( \'Birthday\' => __(\'Birthday\', \'woocommerce\'), \'Anniversary\' => __(\'Anniversary\', \'woocommerce\'), \'Congratulations\' => __(\'Congratulations\', \'woocommerce\'), \'Sorry\' => __(\'Sorry\', \'woocommerce\'), \'Good Luck\' => __(\'Good Luck\', \'woocommerce\'), \'Thank You\' => __(\'Thank You\', \'woocommerce\'), \'Get Well Soon\' => __(\'Get Well Soon\', \'woocommerce\'), \'Love\' => __(\'Love\', \'woocommerce\') ) ); return $fields; } add_action( \'woocommerce_checkout_update_order_meta\', \'occasion_checkout_update_order_meta\' ); function occasion_checkout_update_order_meta( $order_id ){ if( !empty( $_POST[\'occasion\'] ) ) update_post_meta( $order_id, \'_occasion\', sanitize_text_field( $_POST[\'occasion\'] ) ); } add_action( \'woocommerce_admin_order_data_after_billing_address\', \'occasion_edit_woocommerce_checkout_page\', 10, 1 ); function occasion_edit_woocommerce_checkout_page($order){ echo __(\'Occasion\').\': \'.get_post_meta($order->id, \'_occasion\', true ); }

Functions.php上未定义$_GET和&_REQUEST索引

我最近尝试学习为我的自定义主题创建一个主题选项页面，这是按照stackoverflow和其他资源的教程进行的。但脚本显示错误if ($_GET[\'page\'] == basename(__FILE__)) { if (\'save\' == $_REQUEST[\'formaction\']) { foreach ($options as $value) { if( isset( $_REQUEST[ $value[\'id\']
