random color

Hi @djoni7811

If you select the option “Automatically determine background color for each user (Recommended)” the background of the image is determined from the user email. If the users have the same email, the background will be the same. There is also a remote possibility that different emails could have the same background color.
If you can post here the emails, (or at least the generated images in .svg format) so i can check them that would be great.
In case of the images without the letters,
Are you using other plugins? which one?
You “lose” the letters while showing comments? When you create the comment you fill the name and email of the commenter?

kind regards

I removed the ability to leave an email, left only the name field.

How can I generate it only from the name?

This snippet should do the trick (add it to your functions.php).
Keep in mind that your WP_Comment object most have comment_author field set. This is the default wp field for comments author, some plugins use a different field, if so, just make sure you use the correct one.
Let me know if it work for you.

function background_from_nickname( $url_args, $id_or_email ) {

	$user = false;
	if ( $id_or_email instanceof WP_Comment ) {

		if ( ! empty( $id_or_email->user_id ) ) {
			$user = get_user_by( 'id', (int) $id_or_email->user_id );
		}
		if ( ( ! $user || is_wp_error( $user ) ) && ! empty( $id_or_email->comment_author ) ) {
			$hash           = $id_or_email->comment_author . '@localhost.com';//add @localhost.com is optional
			$hash           = md5( strtolower( trim( $hash ) ) );
			$url_args['background'] = substr( $hash, 0, 6 );
		}
	}

	return $url_args;
}

add_filter( 'leira_letter_avatar_url_args', 'background_from_nickname', 10, 2 );

thank you, now everything works
