我从一个answer to a previous question:

add_action(\'add_attachment\', function( $attachmentID ) {
  if ( ! class_exists( \'WC_Product\' ) ) return; // if no WooCommerce do nothing

  // an attachment was jus saved, first of all get the file name
  $src = wp_get_attachment_image_src( $attachmentID, \'full\' );
  $filename = pathinfo( $src[0], PATHINFO_FILENAME );

  // now let\'s see if exits a product with the sku that match filename
  $args = array(
    \'meta_key\' => \'_sku\',
    \'meta_value\' => $filename,
    \'post_type\' => \'product\',
    \'posts_per_page\' => \'1\' // assuming sku is unique get only one post
  );
  $prods = get_posts( $args );
  if ( ! empty($prods) ) {

    // ok we have a match, exists a product having sku that match filename
    $product = array_pop( $prods );

    // set the thumbnail for the product
    set_post_thumbnail( $product, $attachmentID );

    // now "attach" the post to the product setting \'post_parent\'
    $attachment = get_post( $attachmentID );
    $attachment->post_parent = $product->ID;
    wp_update_post( $attachment );
  }
});

当我将图像添加到媒体库时，它将解决我将图像与现有产品匹配的问题。然而，我不知道我需要在wordpress的什么地方添加它。我对这一切都很陌生。

有人能帮忙吗？
