WooCommerce 如何显示特定作者的产品存档信息

WooCommerce how to show Information on Product Archive IF by Certain Author

我想在产品存档页面(商店列表)上回显购物车前的一些文本,但仅限于特定作者的产品。

我有这段代码可以在我想要的地方显示我想要的信息:

add_filter( 'woocommerce_loop_add_to_cart_link', 'tomich_add_melody_vendor', 10, 3 );
function tomich_add_melody_vendor ( $add_to_cart_html, $product, $args )
{
    $before = 'Shop: <img class="vendor-image-tomich" src="https://melodypayne.com/wp-content/uploads/2019/06/cropped-Melody-Payne-Store-Logo-Pic-2019.png" alt="Melody Logo"><span class="tomich-shop-title"><a href="/shop/melodypayne">Melody Payne</a></span></br></br>'; // Some text or HTML here
    $after = ''; // Add some text or HTML here as well

    
    return $before . $add_to_cart_html . $after;
}

但现在我需要弄清楚如何限制它只显示在某个 author 的产品上,可以是 nicknameID

我尝试了此代码的一些变体,但 none 有效。

$author_id = get_post_field('post_author', get_queried_object_id());

if (get_the_author_meta('display_name', $author_id) === 'vivian') {
    // do something
}

您正在将 $product 传递给您的自定义回调函数,因此您可以使用它来获取作者信息,如下所示:

add_filter('woocommerce_loop_add_to_cart_link', 'tomich_add_melody_vendor', 10, 3);

function tomich_add_melody_vendor($add_to_cart_html, $product, $args)
{

  $author_nickname = get_the_author_meta('nickname', $product->post->post_author);

  // OR
  // $author_id = get_the_author_meta('ID', $product->post->post_author);

  // OR
  // $author_name = get_the_author_meta('display_name', $product->post->post_author);

  // You could also get the author with other paramaeters like:
  // display_name
  // first_name
  // ID
  // last_name
  // nickname

  if ($author_nickname == "vivian") { // pass the name you want

    $before = 'my custom element before'; // Some text or HTML here

    $after = 'my custom element after'; // Add some text or HTML here as well


    return $before . $add_to_cart_html . $after;

  } else {

    return $add_to_cart_html;
  }

}

在使用 Wordpress get_post() function you can use another Wordpress function get_userdata() 检索 post 作者后得到用户的昵称和其他数据。

add_filter( 'woocommerce_loop_add_to_cart_link', 'tomich_add_melody_vendor', 10, 3 );
function tomich_add_melody_vendor ( $add_to_cart_html, $product, $args ) {

    // Gets the "WP_Post" object of the product
    $post = get_post( $product->get_id() );

    // Gets the user ID
    $user_id = $post->post_author;

    // Gets "WP_User" object
    $user = get_userdata( $user_id );

    // Gets the user's data
    $user_login    = $user->user_login;
    $user_nicename = $user->user_nicename;
    $user_email    = $user->user_email;
    $display_name  = $user->display_name;

    // run your code here

}

代码已经过测试并且可以工作。将其添加到您的活动主题 functions.php.
