In this article, we aim to clear up your doubts by guiding you on how to return trackback URL in WordPress.
function wpturbo_get_trackback_url() {
global $post;
return get_trackback_url($post->ID);
}

This code snippet is quite straightforward yet vital. It establishes a function called wpturbo_get_trackback_url(), which aim is to fetch and return the trackback URL of a certain post within your WordPress site.
function wpturbo_get_trackback_url() {

}Now, let’s disintegrate the function in order to understand how it works.
The first line inside the function specification, global $post;, means that we are declaring the global variable $post. In the broad world of WordPress, $post is a global instance that contains all data relevant to the current post loaded by the loop, hence it’s the perfect method to retrieve the post ID which we need to get the trackback URL.
The next line, return get_trackback_url($post->ID);, incorporates a native WordPress function known as get_trackback_url(). The purpose of this function is to fetch the trackback URL for a specified post. The post is chosen by passing its ID as a parameter into the function. In this case, the ID is fetched by $post->ID, which refers to the ID of the current global $post.
After the function wpturbo_get_trackback_url() is defined, it is called using the echo statement echo wpturbo_get_trackback_url();. Consequently, the function fetches the trackback URL for the current post and returns it. By echoing the function, the returned trackback URL is displayed wherever this code snippet is used.
