我怎样才能获得Wordpress用户ID？

Question

I want to use the Twitter follow button for site authors on all posts.

The Twitter structure is here:

<a href="https://twitter.com/twitterapi" class="twitter-follow-button" data-show-count="false" data-lang="en">Follow @twitterapi</a>

Yes, it works but this place must be generic. I should import Wordpress $user->ID in this structure. How can I do this?

Answer 1

You can use get_current_user_id() in wordpress.

To get the author of the current post try the following

  <a href="https://twitter.com/<?php esc_attr_e(get_the_author()) ?>" 
     class="twitter-follow-button" 
     data-show-count="false" data-lang="en">Follow @<?php echo get_the_author() ?></a>
