自定义好友按压功能

Question

我写了一个功能来限制用户角色的用户活动更新，每天限制在一定数量。我遇到的问题是，在 switch 语句中，所有案例/块都被跳过并直接进入默认值并忽略所有 wp 角色。

默认不允许任何帖子并给出错误信息

感谢您提供的任何意见。

<?php

// Limit activity posts by day and user role
function limit_activity_posts($user_id)
{
    // get the current user role
    $user_role = get_userdata($user_id)->roles[0];

    // set the maximum number of posts based on user role
    switch ($user_role) {
        case "subscriber":
            $max_posts = 3;
            break;
        case "contributor":
            $max_posts = 5;
            break;
        case "editor":
            $max_posts = 10;
            break;
        case "administrator":
            $max_posts = -1;
            break;
        default:
            $max_posts = 0;
    }

    // check the number of posts for the current user
    $today = strtotime("today midnight");
    $args = [
        "user_id" => $user_id,
        "date_query" => [
            [
                "after" => $today,
                "inclusive" => true,
            ],
        ],
    ];
    $count = bp_activity_get($args, "total");

    // if the maximum number of posts is reached, prevent new post submission
    if ($max_posts >= 0 && $count >= $max_posts) {
        bp_core_add_message(
            sprintf(
                __(
                    "You have reached the maximum number of posts allowed for today (%d).",
                    "buddypress"
                ),
                $max_posts
            ),
            "error"
        );
        bp_core_redirect(bp_get_activity_directory_permalink());
    }
}
add_action("bp_activity_before_save", "limit_activity_posts");

我期待的结果是每个wp角色都有自己的每日限额

这个版本比我原来的版本简单，它是一个带有管理员选项的插件形式。遇到多个问题，所以为了安全起见，我决定只使用 wp codebox 来实现一个功能。
