Change author url in WP to Discourse profile

Product Support WordPress

AI-generated summary

The discussion revolves around changing the author link in WordPress to link to the author’s profile in Discourse. davidkingham initially shared a code snippet that attempts to achieve this goal, but was unable to retrieve the Discourse username from WordPress.

simon suggested using get_user_meta( $user_id, 'discourse_username', true ); to retrieve the Discourse username, where $user_id is the user’s WordPress user ID. However, davidkingham encountered issues implementing this solution.

simon identified the problem and provided a revised code snippet that passes the author’s ID as a parameter to the function and checks if the Discourse username has been set. If it has, the function returns the link to the author’s Discourse profile; otherwise, it returns the default author link.

The revised solution was successfully implemented, and davidkingham expressed gratitude to simon for their assistance.

I would like to change the author link in wordpress posts:

To link to the authors profile in Discourse. I found this snippet which is similar to what I want to achieve, I modified it slightly.

  add_filter( 'author_link', 'change_author_link', 10, 1  );

  function change_author_link($link) {
   $username=get_the_author_meta('user_nicename');


  $link = 'https://community.naturephotographers.network/u/' . $username;
   return $link;
 }

But I don’t know how to retrieve the discourse username from wordpress, the get_the_author_meta('user_nicename'); is what’s tripping me up. Thanks!

For users who have set their Discourse username on WordPress, you can get the username with:

get_user_meta( $user_id, 'discourse_username', true );

$user_id needs to be set to the user’s WordPress user ID. Since it’s possible that not all authors will have set their Discourse username, you should probably check that the value returned isn’t empty before creating the link.

Thanks Simon, any idea why this would not be working?

add_filter( 'author_link', 'change_author_link', 10, 1  );

$user_id=the_author_meta('ID');

function change_author_link($link) {
   $username = get_user_meta( $user_id, 'discourse_username', true );
   $link = 'https://community.naturephotographers.network/u/' .$username;
   return $link;
 }

Yes, $user_id isn’t available inside of your function. You need to pass the author’s id to the function as a parameter. Try this code. It also checks if the Discourse username has been set. If it’s not set, the default author link will be returned.

add_filter( 'author_link', 'wpdc_modify_author_link', 10, 2 );
function wpdc_modify_author_link( $link, $author_id ) {
    $discourse_username = get_user_meta( $author_id, 'discourse_username', true );
    if ( ! empty( $discourse_username ) ) {
        return "https://community.naturephotographers.network/u/$discourse_username";
    }

	return $link;
}

Brilliant, thank you Simon!
