Related Products Woocommerce 3.0+ By Post Author

问题:

I am trying to display the related product which is related to the post author since I only want to show products or the product that was created by the same user

global $post;
$authorid = $post->post_author;

      foreach ( $related_products as $related_product ) :       
      $post_object = get_post( $related_product->$authorid );
      setup_postdata( $GLOBALS['post'] =& $post_object );
      wc_get_template_part( 'content', 'product' ); 
      endforeach; 

however it doesn't show anything

You could do something like this which will remove any products not created by the product's author from the related products array. Place this code in your functions.php file.

add_filter('woocommerce_related_products', 'show_related_products_post_author', 10, 3 );

function show_related_products_post_author( $related_posts, $product_id, $filters ) {
    $author_id = get_post_field( 'post_author', $product_id );

    $query = new WC_Product_Query( array(
        'limit' => -1,
        'return' => 'ids',
    ) );

    $products = $query->get_products();

    foreach( $products as $loop_product_id ) {
        $product_author_id = get_post_field( 'post_author', $loop_product_id );

        if( $product_author_id !== $author_id ) {
            $key = array_search($loop_product_id, $related_posts);
            unset($related_posts[$key]);
        }
    }

    return $related_posts;
}
