How to remove Author Tag from being visible in Discord's previews? - wordpress

Question

When sharing a post to Discord, the preview Discord generates shows the author name and URL. We removed all information about the author but it didn't stop the author tag from showing.

Answer 1

That’s done via oEmbed. Add below code in your functions.php file
add_filter( 'oembed_response_data', 'disable_embeds_filter_oembed_response_data_' );
function disable_embeds_filter_oembed_response_data_( $data ) {
unset($data['author_url']);
unset($data['author_name']);
return $data;
}
**disorc may have stored the response in cache so create new post or page and test that **

#hrak has the right idea but his answer lacks context for those of us not used to dealing with PHP.
What I ended up doing was check if there was already a filter for 'oembed_response_data' in /wp-includes/default-filters.php. Mine looked like this:
add_filter( 'oembed_response_data', 'get_oembed_response_data_rich', 10, 4 );
Add the previous line to the specified file if, for whatever reason, it isn't there already.
Afterward, I checked in wp-includes/embed.php for the get_oembed_response_data_rich function, which looked like this:
function get_oembed_response_data_rich( $data, $post, $width, $height ) {
$data['width'] = absint( $width );
$data['height'] = absint( $height );
$data['type'] = 'rich';
$data['html'] = get_post_embed_html( $width, $height, $post );
// Add post thumbnail to response if available.
$thumbnail_id = false;
if ( has_post_thumbnail( $post->ID ) ) {
$thumbnail_id = get_post_thumbnail_id( $post->ID );
}
if ( 'attachment' === get_post_type( $post ) ) {
if ( wp_attachment_is_image( $post ) ) {
$thumbnail_id = $post->ID;
} elseif ( wp_attachment_is( 'video', $post ) ) {
$thumbnail_id = get_post_thumbnail_id( $post );
$data['type'] = 'video';
}
}
if ( $thumbnail_id ) {
list( $thumbnail_url, $thumbnail_width, $thumbnail_height ) = wp_get_attachment_image_src( $thumbnail_id, array( $width, 99999 ) );
$data['thumbnail_url'] = $thumbnail_url;
$data['thumbnail_width'] = $thumbnail_width;
$data['thumbnail_height'] = $thumbnail_height;
}
return $data;
}
I just added the two lines of code that #hrak introduced in his answer to remove the author tag (name and URL) from $data before it was returned:
function get_oembed_response_data_rich( $data, $post, $width, $height ) {
(...)
if ( $thumbnail_id ) {
list( $thumbnail_url, $thumbnail_width, $thumbnail_height ) = wp_get_attachment_image_src( $thumbnail_id, array( $width, 99999 ) );
$data['thumbnail_url'] = $thumbnail_url;
$data['thumbnail_width'] = $thumbnail_width;
$data['thumbnail_height'] = $thumbnail_height;
}
unset($data['author_url']);
unset($data['author_name']);
return $data;
}
As before, add the get_oembed_response_data_rich function if it does not already exist. After about 5-10 minutes, Discord link embeds stopped showing the author tag.

I've done this by emptying the posted_by function like this article shows, in the "Use Code to Remove the Author Name" section
https://wpdatatables.com/how-to-hide-the-author-in-wordpress/
basically find the posted_by function and empty it
function twentynineteen_posted_by() {
}
endif;
