WooCommerce：管理员中的动态自定义结帐字段-Java 学习之路

我在向订单管理员添加自定义结帐字段时遇到问题（也许是电子邮件，我还没有） . 抛开编码问题，我大部分都遵循https://www.kathyisawesome.com/woocommerce-customize-checkout-fields/ - 这是我的代码到目前为止：

http://pastebin.com/y8LDcDxS

我假设购物车中有一个产品，我会根据产品数量添加'x'数量的$ fields ['extra_fields'] . 我正在努力使用kia_display_order_data_in_admin（） - 无论我做什么，我都会不断地通过get_country（） . 我在pastebin中得到了非动态变化（基于购物车中有两个产品） - 我试图让这部分动态的其他一切都行不通 .

我看到一些选项可以在管理员中加载这些动态字段但我无法到达那里：

再次获取产品数量并将$ i附加到标准字段名称的末尾
以某种方式获取所有字段的数组，以便我可以提取$ fields ['extra_fields']
通过order_id获取extra_fields post meta
别的什么？

EDIT: 在尝试更新admin kia_save_extra_details() 中的订单详细信息后，Kia 's help, I have revised the code a little and it will now dynamically add custom checkout fields. This works all the way up to the admin order screen, but won'工作

EDIT 2: 请参阅下面接受的答案，因为这适用于我的问题

您确定Product Add-Ons可能不适合这个吗？如果没有，我认为你需要的是自定义输入类型 . 这应该让你开始 .

/* Add a new checkout field 
 * 
 * These is our base field group, later on, depending on product quanitiy, $key = 'passenger_title_1' for example
 * 
 */

function supreme_filter_checkout_fields($fields){
    $fields['extra_fields'] = array(
    'passenger_details' => array(
        'type' => 'passenger_details',
        'required'      => false,
        'label' => __( 'Passenger Details' )
        ),
    );

    return $fields;

}
add_filter( 'woocommerce_checkout_fields', 'supreme_filter_checkout_fields' );

什么是"passenger_details"输入？好吧，我们要定义一下，因为 woocommerce_form_field() 有一个catch，以防该类型没有't match any of WooCommerce'的默认值 . 见'woocommerce_form_field_' . $args['type']

这是我们要为每位乘客列出您想要的字段组的地方 .

function supreme_filter_checkout_field_group( $field, $key, $args, $value ){
    $op_cart_count = WC()->cart->get_cart_contents_count();

    $html = '';

    for ( $i = 1; $i <= $op_cart_count; $i++) {

        $html .= woocommerce_form_field( "passenger_details[$i][title]", array( 
            "type" => "select",
            "return" => true,
            "value" => "",
            "options" => array( "mr" => __( "Mr" ), "mrs" => __( "Mrs" ), "miss" => __( "Miss" ) ),
            "required"      => false,
            "label" => __( "Title" )
            )
        );
        $html .= woocommerce_form_field( "passenger_details[$i][first_name]", array(
            "type" => "text",
            "return" => true,
            "value" => "",
            "required"      => false,
            "label" => __( "First Name" )
            )
        );
        $html .= woocommerce_form_field( "passenger_details[$i][middle_name]", array(
            "type" => "text",
            "return" => true,
            "value" => "",
            "required"      => false,
            "label" => __( "Middle Name" )
            )
        );
        $html .= woocommerce_form_field( "passenger_details[$i][last_name]", array(
            "type" => "text",
            "return" => true,
            "value" => "",
            "required"      => false,
            "label" => __( "Last Name" )
            )
        );
        $html .= woocommerce_form_field( "passenger_details[$i][date_of_birth]", array(
            "type"          => "text",
            "return" => true,
            "value" => "",
            "class"         => array("date-of-birth form-row-wide"),
            "required"      => false,
            "label"         => __("Date of Birth"),
            "placeholder"       => __("Select Date"),
            "options"     =>   array("" => __("Date of Birth", "woocommerce" ))
            )
        );
        $html .= woocommerce_form_field( "passenger_details[$i][dietary_required]", array(
            "type" => "select",
            "return" => true,
            "value" => "",
            "class"         => array("dietary-required form-row-wide"),
            "options" => array( "" => __( "Please Select" ), "y" => __( "Yes" ), "n" => __( "No" ) ),
            "required"      => false,
            "label" => __( "Dietary Requirements?" )
            )
        );
        $html .= woocommerce_form_field( "passenger_details[$i][dietary_preference]", array(
            "type" => "select",
            "return" => true,
            "value" => "",
            "class"         => array("dietary-requirements form-row-wide"),
            "options" => array( "v" => __( "Vegetarian" ), "GF" => __( "Gluten Free" ) ),
            "required"      => false,
            "label" => __( "Meal Preferences" )
            )
        );

    }
    return $html;
}
add_filter( 'woocommerce_form_field_passenger_details', 'supreme_filter_checkout_field_group', 10, 4 );



// display the extra field on the checkout form
function supreme_extra_checkout_fields(){ 

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

    foreach ( $checkout->checkout_fields['extra_fields'] as $key => $field ) :

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

    endforeach;


}
add_action( 'woocommerce_checkout_after_customer_details' ,'supreme_extra_checkout_fields' );

EDIT 处理清理和保存数据 . 请注意，我更改了上面的 supreme_filter_checkout_field_group 函数并删除了ID参数 .

~~使用 id 参数，我们可以动态设置输入名称 . 得到的标记应该是这样的：~~

<input type="text" class="input-text " name="last_name" id="passenger_details[2]last_name" placeholder="" value="">

这是错的 . name 参数需要是一个数组！名称是从 woocommerce_form_field() 的第一个参数中提取的 . ID与我们的需求无关，但需要保持唯一以保持正确的标记 . 这是我们需要的结果，现在应该通过上述修改得到：

<input type="text" class="input-text " name="passenger_details[2][last_name]" id="passenger_details[2][last_name]" placeholder="" value="">

现在提交 $_POST['passenger_data'] 应该是阵列（乘客）阵列（乘客详情） . 在我编辑之后，它就是！

现在，为了处理这些数据并清理乘客数据中的各个字段，我们创建了一个清理自定义字段类型的功能：

/**
 * Sanitize our custom field
 * 
 */
function supreme_custom_process_checkout_field_passenger_details( $posted ){

    $clean = array();

    foreach( $posted as $passenger ){
        $details = supreme_custom_checkout_clean_passenger_details( $passenger );

        if( ! empty( $details ) ){
            $clean[] = $details;
        }
    }

    return $clean;
}
add_filter( 'woocommerce_process_checkout_passenger_details_field', 'supreme_custom_process_checkout_field_passenger_details' );


function supreme_custom_checkout_clean_passenger_details( $passenger = array() ){
    $details = array();
    if( isset( $passenger["title"] ) ){
        $details['title'] = sanitize_text_field( $passenger["title"] );
    }
    if( isset( $passenger["first_name"] ) ){
        $details['first_name'] = sanitize_text_field( $passenger["first_name"] );
    }
    if( isset( $passenger["middle_name"] ) ){
        $details['middle_name'] = sanitize_text_field( $passenger["middle_name"] );
    }
    if( isset( $passenger["last_name"] ) ){
        $details['last_name'] = sanitize_text_field( $passenger["last_name"] );
    }
    if( isset( $passenger["date_of_birth"] ) ){
        $details['date_of_birth'] = $date = preg_replace("([^0-9/])", "", $passenger["date_of_birth"] );
    }
    if( isset( $passenger["dietary_required"] ) ){
        $details['dietary_required'] = $passenger["dietary_required"] == "y" ? "y": "n";
    }
    if( isset( $passenger["dietary_preference"] ) && isset( $passenger["dietary_required"] ) && $passenger["dietary_required"] == "y" ){
        $details['dietary_preference'] = $passenger["dietary_preference"] == "GF" ? "GF": "v";
    }
    return $details;
}

现在它已被清理，更新只是保存post meta的问题：

/**
 * update_post_meta
 * 
 */
function supreme_custom_checkout_field_update_order_meta( $order_id, $posted ){

    if( ! empty( $posted["passenger_details"] ) ){
        update_post_meta( $order_id, "_passenger_details", $posted["passenger_details"] );
    } else {
        delete_post_meta( $order_id, "_passenger_details" );
    }

}
add_action( 'woocommerce_checkout_update_order_meta', 'supreme_custom_checkout_field_update_order_meta', 10, 2 );

现在，我们肯定已经将所有字段保存在 _passenger_details post元组中，并且我们可以在需要显示它时循环遍历该数组 . 例如，它位于管理员订单页面上：

// display the extra data in the order admin panel
function kia_display_order_data_in_admin( $order ){  

    $passenger_details = get_post_meta( $order->id, "_passenger_details", true ); 

    if( ! empty( $passenger_details ) ) { 

        $passenger_defaults = array(
                "title" => "",
                "first_name" => "",
                "middle_name" => "",
                "last_name" => "",
                "date_of_birth" => "",
                "dietary_required" => "",
                "dietary_preference" => ""
            );

    ?>
    <div class="passenger_data">
        <h4><?php _e( "Passenger Details", "your-slug" ); ?></h4>
        <?php 
            $i = 1;

            foreach( $passenger_details as $passenger ){

                $passenger = wp_parse_args( $passenger, $passenger_defaults );

                echo "<p><strong>" . sprintf( __( "Passenger #%s", "your-slug" ), $i  ) . "</strong>" . "
";
                echo __( "Title", "your-slug" ) . ' : ' . $passenger["title"] . "
";
                echo __( "First Name", "your-slug" ) . ' : ' . $passenger["first_name"] . "
";
                echo __( "Middle Name", "your-slug" ) . ' : ' . $passenger["middle_name"] . "
";
                echo __( "Last Name", "your-slug" ) . ' : ' . $passenger["last_name"] . "
";
                echo __( "Date of Birth", "your-slug" ) . ' : ' . $passenger["date_of_birth"] . "
";
                echo __( "Dietary Required", "your-slug" ) . ' : ' . $passenger["dietary_required"] . "
";
                echo __( "Dietary Preference", "your-slug" ) . ' : ' . $passenger["dietary_preference"] . "
";

                echo "</p>";

                $i++;

            }

         ?>
    </div>
<?php }
}
add_action( "woocommerce_admin_order_data_after_order_details", "kia_display_order_data_in_admin" );

这仍然留下了谢谢你的页面和电子邮件，但数据就在那里 .
