如果您正在使用Mvc来构建用户配置文件,那么最好是使用条件语句来计算模型或控制器中函数的注释的显示类型,如下所示：

例如
我有3节课

>评论
>会员
> Admin(扩展成员)

一些示例使用伪代码,其中缺少函数

选项1

依赖于登录showComments函数的用户类型,返回注释将返回不同的信息.

class user {

    function isLOGgedIn() { //Check if a user is logged in }

    function getUserTyPE() { // return user type }

    function showComments($id) { //comments code }
}

class admin extends user {
    function showComments($id) { //comments code }
}

然后使用控制器中的代码来确定依赖于登录的用户类型显示哪个？

$PRofileContent = $user->getOtherContent();

if ($user->isLoggedIn() && $user->getUserType() == "member") {
    $member = new member();
    $comments = $member->showComments($profileid);
}
elseif ($user->isLoggedIn() && $user->getUserType() == "admin") {
    $admin = new admin();
    $comments = $admin->showComments($profileId);
}
else
    $comments = $user->showComments($profileId);

require 'templates/profile.PHP';

选项2

由于这是一个自定义框架,我可以将所有内容移动到模型中的函数中,并在用户中使用一个函数来检查要显示的注释类型：

abstract class user {

    function isLoggedIn() { //Check if a user is logged in }

    function getUserType() { // return user type }

}

class profile {

    function showComments($profileId,$user) {

        if (User::isLoggedIn() && User::getUserType() == "member") {
            $comments = //database query and formatting for member
        }
        elseif (User::isLoggedIn() && User::getUserType() == "admin") {
            $comments = //database query and formatting for admin
        }
        else
           $comments = //database query and formatting for guest

        return $comments;
    }
}

使用如下控制器：

$profile = new profile($profileId);
$comments = $profile->showComments();

require 'templates/profile.PHP';

class user {
    function isLoggedIn() {}
    function getUserType() {}
    function showComments() {}
}

class admin extends user {
    function getUserType() {}
    function showComments() {}
}

class member extends user {
    function getUserType() {}
    function showComments() {}
}

if ($user->isLoggedIn()) {
    $comments = $user->showComments($profileId);
}
