更改评论作者显示名称

我试图将评论作者的名字（或者更具体地说，WooCommerce中的评论作者）改为名字的首字母（例如，“John D.”代表“John Doe”）。

我通过以下函数中的代码获得了大部分方法。php，但出于某种原因（可能是因为评论/评论是如何提交的），它倾向于将名称留空，并用句号（“.”）替换在一些（并非全部）评论中。

add_filter(\'get_comment_author\', \'my_comment_author\', 10, 1);

function my_comment_author( $author = \'\' ) {
    // Get the comment ID from WP_Query

    $comment = get_comment( $comment_ID );

    if ( empty($comment->comment_author) ) {
        if (!empty($comment->user_id)){
            $user=get_userdata($comment->user_id);
            $author=$user->first_name.\' \'.substr($user->last_name,0,1).\'.\'; // this is the actual line you want to change
        } else {
            $author = __(\'Anonymous\');
        }
    } else {
        $user=get_userdata($comment->user_id);
        $author=$user->first_name.\' \'.substr($user->last_name,0,1).\'.\'; // this is the actual line you want to change
    }
    return $author;
}

但是，如果我将代码这样调整为回退，它总是显示全名：

add_filter(\'get_comment_author\', \'my_comment_author\', 10, 1);

function my_comment_author( $author = \'\' ) {
    // Get the comment ID from WP_Query

    $comment = get_comment( $comment_ID );

    if ( empty($comment->comment_author) ) {
        if (!empty($comment->user_id)){
            $user=get_userdata($comment->user_id);
            $author=$user->first_name.\' \'.substr($user->last_name,0,1).\'.\'; // this is the actual line you want to change
        } else {
            $author = __(\'Anonymous\');
        }
    } else {
        $author = $comment->comment_author;
    }

    return $author;
}

我希望数据库中的实际名称保持不变，只需过滤网站面向公众一侧的输出以获取评论（我们可能需要在其他地方显示他们的全名，但在评论作者正确显示之前无法真正测试）。

add_filter( \'comment_author\', \'custom_comment_author\', 10, 2 ); function custom_comment_author( $author, $commentID ) { $comment = get_comment( $commentID ); $user = get_user_by( \'email\', $comment->comment_author_email ); if( !$user ): return $author; else: $firstname = get_user_meta( $user->ID, \'first_name\', true ); $lastname = get_user_meta( $user->ID, \'last_name\', true ); if( empty( $firstname ) OR empty( $lastname ) ): return $author; else: return $firstname . \' \' . $lastname; endif; endif; }

add_filter(\'get_comment_author\', \'comments_filter_uprise\', 10, 1); function comments_filter_uprise( $author = \'\' ) { $comment = get_comment( $comment_author_email ); if ( !empty($comment->comment_author_email) ) { if (!empty($comment->comment_author_email)){ $user=get_user_by(\'email\', $comment->comment_author_email); $author=$user->first_name.\' \'.substr($user->last_name,0,1).\'.\'; } else { $user = get_user_by( \'email\', $comment->comment_author_email ); $author = $user->first_name; } } else { $user=get_userdata($comment->user_id); $author=$user->first_name.\' \'.substr($user->last_name,0,1).\'.\'; $author = $comment->comment_author; } return $author; }
