我试图私下发表评论。我的意思是评论必须对帖子作者和评论作者可见。我创建自定义注释节“；更好的评论。php；。我使用了pre\\u get\\u评论，但我无法工作。请帮忙
<?php
// My custom comments output html
function better_comments( $comment, $args, $depth ) {
// Get correct tag used for the comments
if ( \'div\' === $args[\'style\'] ) {
$tag = \'div\';

} else {
$tag = \'li\';
$add_below = \'div-comment\';
} ?>

您可以使用pre_get_comments 筛选以在获取注释之前修改注释查询的参数。特别是author_in 参数
我试着写一个例子，虽然我还没有测试过，但它类似于这样：
add_action( \'pre_get_comments\', \'author_and_self_comment_filter\' );
function author_and_self_filter( \\WP_Comment_Query $query ) : void {
// We need to do some checks first and return early if
// this filter doesn\'t apply, e.g. if you\'re the post
// author etc
// don\'t break the admin UI
if ( is_admin() ) {
return;
}
// only filter if we\'re grabbing the comments for a post
if ( $query->query_vars[\'post_id\'] === 0 ) {
return;
}
// only logged in users should see comments
if ( ! is_user_logged_in() ) {
// we need to return 0 results so I\'m asking for a
// comment type that doesn\'t exist so there are no
//results, there\'s probably a better way to do this:
$query->query_vars[\'type\'] = \'banana\';
return;
}
// this is already filtered to specific people! Skip!
if ( ! empty( $query->query_vars[\'author__in\'] ) ) {
return;
}
// Admins + super admins see everything!
if ( current_user_can( \'manage_options\' ) || is_super_admin() ) {
return;
}
// get my ID
$my_user_id = get_current_user_id();
// get the post author ID
$post_id = $query->query_vars[\'post_id\'];
$p = get_post( $post_id );
$post_author_id = $p->post_author;
// If I\'m the post author then I can see everything
if ( $my_user_id === $post_author_id ) {
return;
}
// now we need to set the `author_in` to an array with 2
// values, the authors user ID and the current users ID
$authors = [];
$authors[] = $my_user_id; // My user ID
$authors[] = $post_author_id; // Author ID
$query->query_vars[\'author_in\'] = $authors;
}
有一系列的检查来确定我们是否需要这样做，然后在最后我们将评论限制为仅针对作者和当前用户。
请注意，如果这样做，注释计数器将永远不会准确，并且可能非常不可靠。如果不取消限制，则无法对此进行修复，因此所有用户都可以看到所有注释。
