概述

comment_post_redirect 是一个 WordPress 过滤器，用于在用户提交评论后重定向到指定 URI。它允许开发者自定义重定向位置，例如在自定义页面中处理评论时保持页面跳转。

关键要点

  • 过滤器名称：comment_post_redirect
  • 参数：$location（重定向 URI 字符串）和 $comment（WP_Comment 对象）
  • 用途：修改评论提交后的重定向目标，常用于自定义页面或特定帖子类型
  • 引入版本：WordPress 2.0.5

代码示例

add_filter( 'comment_post_redirect', 'redirect_comments', 10, 2 );
function redirect_comments( $location, $commentdata ) {
  if ( ! isset( $commentdata ) || empty( $commentdata->comment_post_ID ) ) {
    return $location;
  }
  $post_id = $commentdata->comment_post_ID;
  if ( 'my-custom-post' == get_post_type( $post_id ) ) {
    return wp_get_referer() . "#comment-" . $commentdata->comment_ID;
  }
  return $location;
}

注意事项

  • 使用此过滤器时，需同时处理 comment_reply_link 过滤器以修改评论回复链接
  • 确保检查 $commentdata 参数的有效性，避免空值错误

    Sometimes you want to build a page with various custom posts displayed on the same page and use one of these post’s comments to handle the page comments. However, when you submit a comment associate with a given post, the submit button redirects you to that post’s permalink, and not to your original page. To overcome this, you need to filter the redirect location such as,

    add_filter( 'comment_post_redirect', 'redirect_comments', 10,2 );
function redirect_comments( $location, $commentdata ) {
  if(!isset($commentdata) || empty($commentdata->comment_post_ID) ){
    return $location;
  }
  $post_id = $commentdata->comment_post_ID;
  if('my-custom-post' == get_post_type($post_id)){
    return wp_get_referer()."#comment-".$commentdata->comment_ID;
  }
  return $location;
}

    Don’t forget to also change the ‘Reply’ button links on comments using the filter comment_reply_link
