Php 添加用户'；用户元数据中的注释计数

我使用以下代码获取用户在其他用户帖子上发表的总评论（不包括用户自己帖子上发表的评论）：

现在，我想用这个值更新所有用户的。因此，

$meta\u值

将是评论总数（如上所示），而

$meta\u键

可以是

自定义用户\u评论

如何为所有用户添加此元数据？以及如何使其在用户对其他用户的帖子发表评论时更新值？

使用插件：

• 在插件激活时修改所有用户元
• 检查每个张贴的评论，必要时更新

您必须使用每个函数中提供的用户ID来填补空白：

<?php
/**
 * Plugin Name: (SO) Comment to User Meta
 * Plugin URI: http://stackoverflow.com/a/25464099/1287812
 * Author: brasofilo
 */

/**
 * Modify all user meta on plugin activation
 */
register_activation_hook(   __FILE__, function() 
{
    # Security checks
    if ( ! current_user_can( 'activate_plugins' ) )
        return;

    $plugin = isset( $_REQUEST['plugin'] ) ? $_REQUEST['plugin'] : '';
    check_admin_referer( "activate-plugin_{$plugin}" );

    # ITERATE THROUGH USERS AND UPDATE METADATA
    foreach( get_users() as $user ) 
    {
        # http://codex.wordpress.org/Function_Reference/update_user_meta
        #
        $user_comment_count = grab_custom_user_comments_count( $user->data->ID );
    }
});

/**
 * Update user meta on comment post
 * looks like this hook only runs for logged users, checking for that just to be safe
 *
 * @param $id           Comment ID
 * @param $comment_obj  Full comment details
 */
add_action( 'wp_insert_comment', function( $id, $comment_obj ) 
{
    # Only on backend and for logged users
    if( is_admin() || !is_user_logged_in() )
        return; 

    # CURRENT LOGGED USER
    global $user_ID;
    get_currentuserinfo();

    # POST AUTHOR
    # http://codex.wordpress.org/Function_Reference/update_user_meta
    #
    $user_comment_count = grab_custom_user_comments_count( $comment_obj->user_id );
    // You can compare $user_ID and $comment_obj->user_id here
}, 10, 2 );

谢谢你的回答。如果可能的话，我需要进一步的澄清。首先，不推荐使用update\u usermeta，需要使用update\u user\u meta。请添加用户ID，以便我了解如何插入该ID？此外，该值是否仅在用户在其他人的帖子上发表评论时更新？因此，如果用户在自己的帖子上发表评论，值不会改变。是的，我从谷歌复制了URL，正确的是

update\u user\u meta

。我已经用一些用法示例和更多注释更新了答案，以澄清您的疑问。我的朋友，您为我节省了很多时间的麻烦，非常感谢！
