将自定义列添加到 woocommerce 报告 - csv

Question

我有一个问题 - 是否可以在 woocommerce 中的 csv 导出文件中再添加一列（它将显示来自自定义字段的数据）？每个订单的所有必要数据都存储为 meta_key: 'authors_income'。我不知道怎么做。我尝试修改以下代码，但它不起作用：

function wpg_add_columns($cols) {
    $cols['wc_settings_tab_payment_method'] = __('Payment Method', 'mytheme');
    return $cols;
}
add_filter('wpg_order_columns', 'wpg_add_columns');

Answer 1

这应该可以。让我知道这是怎么回事。

<?php

//Step 1: Add field to column
function wpg_add_columns($cols) {

    $cols['wc_settings_tab_authors_income'] = __('Authors Income', 'mytheme');
    return $cols;
}
add_filter('wpg_order_columns', 'wpg_add_columns');


//Step 2: Add same column to settings, so that it will appear in settings page.
function wpg_add_fields($settings) {

    $settings['authors_income'] = array(
                                'name' => __( 'Authors Income', 'woocommerce-simply-order-export' ),
                                'type' => 'checkbox',
                                'desc' => __( 'Authors Income', 'woocommerce-simply-order-export' ),
                                'id'   => 'wc_settings_tab_authors_income'
                            );

    return $settings;

}
add_filter('wc_settings_tab_order_export', 'wpg_add_fields');


//Note: Notice that in above step, id attribute is identical to that of array key in step 1. ( wc_settings_tab_authors_income )
//Step 3: Add it to csv.
function csv_write( &$csv, $od, $fields ) {

    if( !empty( $fields['wc_settings_tab_authors_income'] ) && $fields['wc_settings_tab_authors_income'] === true ){
        $authors_income = get_post_meta( $od->id, 'authors_income', true );
        array_push( $csv, $authors_income );
    }

}
add_action('wpg_add_values_to_csv', 'csv_write', 10, 3);
