php - 如何获取 Woocommerce 当前版本 ID？

Question

我正在尝试在我的 Woocommerce 后端创建一些附加功能，我在其中将自定义字段添加到 Woocommerce 后端的变体部分。然而，我终其一生都无法弄清楚如何获取当前变体 ID，以便我可以获得帖子元数据。

这是我一直在使用的:

<?php

        // Get variations
        $args = array(
                     'post_type'     => 'product_variation',
                     'post_status'   => array( 'private', 'publish' ),
                     'numberposts'   => -1,
                     'orderby'       => 'menu_order',
                     'order'         => 'asc',
                     'post_parent'   => $post->ID
                 );
                 $variations = get_posts( $args ); 

        foreach ( $variations as $variation ) {

                     $variation_id           = absint( $variation->ID );$variable_id = $this['variation_id'];
                     $variation_post_status  = esc_attr( $variation->post_status );
                     $variation_data         = get_post_meta( $variation_id );
                     $variation_data['variation_post_id'] = $variation_id;
                    echo get_post_meta( $variation_data['variation_post_id'], '_my_custom_field', true) . ' - TEST';

                 }

     ?>

当我检查后端时，它似乎正在将所有后元数据拉入每个变体，如下所示:

但是，如果我使用如下所示的实际变体 ID，那么它适用于该变体:

echo get_post_meta( 134, '_my_custom_field', true) . ' - Test Variation #134';

@德里克，

您试图在模板的哪个位置显示自定义字段数据？

如果它在产品循环中，你可以这样做:

<?php
    // Get the post IDs of all the product variations
    $variation_ids = $product->children;

    // Each product variation id
    foreach( $variation_ids as $var_id ) :

        // Get all of the custom field data in an array
        $all_cfs = get_post_custom($var_id); 

        // Show all of the custom fields    
        var_dump($all_cfs); 

        // Get specific data from the certain custom fields using get_post_meta( $post_id, $key, $single );
        $test = get_post_meta( $var_id, '_text_field', true );

    endforeach;
?>
