我正在使用PHP在我的localhost上创建一个竞赛网站。该项目的工作原理如下：
用户可以登录并定向到页面level.php?n=getUserData()['level']，逻辑是如果用户提交正确答案，则用户被重定向到下一级别，并且数据库中的级别字段必须更新，以便用户可以重定向到下一级level.php?n=2等等......在登录期间，用户凭据存储在会话变量中。（user_id，level，{{ 1}} ..等等。
我的登录控制器：
email我的验证课程：
include 'core/init.php';
$id = isset($_GET['n']) ? $_GET['n'] : null;
$validate = new Validator;
$template = new Template("templates/question.php");
$template->title = $validate->getQuestion($id)->body;
//$template->answer = $validate->getQuestion($id)->answer;
$userid = getUserData()['user_id'];
if(isset($_POST['submit']))
{
// echo getUserData()['level']; die();
$data = array();
$data['answer'] = $_POST['answer'];
$required_fields = array("answer");
if($validate->isRequired($required_fields))
{
if($validate->check_answer($_POST['answer']))
{
if($validate->update_level($userid))
{
redirect("level.php?n=".getUserData()['level'],"Correct Anwser","success");
}

else

redirect("level.php?n=".getUserData()['level'],"Incorrect","error");

功能：
getUserData()答案 0 :(得分：0)
我相信当用户得到正确答案时，您的问题就在您的更新部分中。您需要更新会话。我建议您重新编写脚本，将getUserData()转换为User类或类似内容：
include('core/init.php');
$id = (isset($_GET['n']))? $_GET['n'] : null;
$validate = new Validator;
$template = new Template("templates/question.php");
# Create User class
$User = new User();
# Create make sure you set the files to internal array
$User->init();
# Start template
$template->title = $validate->getQuestion($id)->body;
# Fetch the id here
$userid = $User->getUserId();
# Check post
if(isset($_POST['submit'])) {
$data = array();
$data['answer'] = $_POST['answer'];
$required_fields = array("answer");
if($validate->isRequired($required_fields)) {
if($validate->check_answer($_POST['answer'])) {
# Update the database
if($validate->update_level($userid)) {
# Increment the init() here to push the level up
redirect("level.php?n=".$User->init(1)->getLevel(),"Correct Anwser","success");
}
}
else {
# Since you are not updating, don't need the init() here
redirect("level.php?n=".$User->getLevel(),"Incorrect","error");
}
}
else {
# Since you are not updating, don't need the init() here
redirect("level.php?n=".$User->getLevel(),"Empty","error");
}
}
echo $template;
创建用户类
用户类
<?php
class User
{
private $userData;
public function init($increment = 0)
{
# Get the current level
$level = $_SESSION['level'];
# If there is an increment
if($increment > 0) {
# Increment the level
$level += $increment;
# !!!***Re-assign the session***!!!
$_SESSION['level'] = $level;
}
# Save the internal array
$userarray['username'] = $_SESSION['username'];
$userarray['user_id'] = $_SESSION['user_id'];
$userarray['email'] = $_SESSION['email'];
# Level will be set by variable now
$userarray['level'] = $level;
# Save to array
$this->userData = (object) $userarray;
# Return object for chaining
return $this;
}
# This will call data from your internal array dynamically
public function __call($name,$args=false)
{
# Strip off the "get" from the method
$name = preg_replace('/^get/','',$name);
# Split method name by upper case
$getMethod = preg_split('/(?=[A-Z])/', $name, -1, PREG_SPLIT_NO_EMPTY);
# Create a variable from that split
$getKey = strtolower(implode('_',$getMethod));
# Checks if there is a key with this split name
if(isset($this->userData->{$getKey}))
$getDataSet = $this->userData->{$getKey};
# Checks if there is a key with the raw name (no get though)
elseif(isset($this->userData->{$name}))
$getDataSet = $this->userData->{$name};
# Returns value or bool/false
return (isset($getDataSet))? $getDataSet : false;
}
}
